Visitors to Robert H. Treman park think nothing of crushing millipedes on the trail, it is concerning to encounter evidence of such disrespectful and boorish behavior. Here is an intact millipede I found last week.
Millipedes are a group of arthropods that are characterized by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name “millipede” derives from Latin for “thousand feet”, no species was known to have 1,000 or more until the discovery of Eumillipes persephone, which can have over 1,300 legs.
There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi or drink plant fluids, and a small number are predatory.
Millipedes are generally harmless to humans, although some can become household or garden pests. Millipedes can be an unwanted nuisance particularly in greenhouses where they can potentially cause severe damage to emergent seedlings. Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles. Its primary defense mechanism is to curl into a tight coil, thereby protecting its legs and other vital delicate areas on the body behind a hard exoskeleton. Reproduction in most species is carried out by modified male legs called gonopods, which transfer packets of sperm to females.
Millipedes are among the first animals to have colonized land during the Silurian period. Early forms probably ate mosses and primitive vascular plants. Millipedes also exhibit the earliest evidence of chemical defense, as some Devonian fossils have defensive gland openings called ozopores. Millipedes, centipedes, and other terrestrial arthropods attained very large sizes in comparison to modern species in the oxygen-rich environments of the Devonian and Carboniferous periods, and some could grow larger than one meter. As oxygen levels lowered through time, arthropods became smaller.
Most millipedes are detritivores and feed on decomposing vegetation, feces, or organic matter mixed with soil. They often play important roles in the breakdown and decomposition of plant litter: estimates of consumption rates for individual species range from 1 to 11 percent of all leaf litter, depending on species and region, and collectively millipedes may consume nearly all the leaf litter in a region. The leaf litter is fragmented in the millipede gut and excreted as pellets of leaf fragments, algae, fungi, and bacteria, which facilitates decomposition by the microorganisms.

Our home at Malloryville, New York has an orchard of three apple trees, seen here on early one spring morning in the year 2010. The varieties are Delicious, Cortland and McIntosh. Freeville, Tompkins County, New York State
The original wild ancestor of Malus domestica was Malus sieversii, found growing wild in the mountains of Central Asia in southern Kazakhstan, Kyrgyzstan, Tajikistan, and northwestern China. Cultivation of the species, most likely beginning on the forested flanks of the Tian Shan mountains, progressed over a long period of time and permitted secondary introgression of genes from other species into the open-pollinated seeds.
Chinese soft apples, such as M. asiatica and M. prunifolia, have been cultivated as dessert apples for more than 2000 years in China. These are thought to be hybrids between M. baccata and M. sieversii in Kazakhstan.
Among the traits selected for by human growers are size, fruit acidity, color, firmness, and soluble sugar. Unusually for domesticated fruits, the wild M. sieversii origin is only slightly smaller than the modern domesticated apple.
At the Sammardenchia-Cueis site near Udine in Northeastern Italy, seeds from some form of apples have been found in material carbon dated to around 4000 BCE.[20] Genetic analysis has not yet been successfully used to determine whether such ancient apples were wild Malus sylvestris or Malus domesticus containing Malus sieversii ancestry. It is generally also hard to distinguish in the archeological record between foraged wild apples and apple plantations.
There is indirect evidence of apple cultivation in the third millennium BCE in the Middle East. There was substantial apple production in the European classical antiquity, and grafting was certainly known then. Grafting is an essential part of modern domesticated apple production, to be able to propagate the best cultivars; it is unclear when apple tree grafting was invented.
The proverb, “An apple a day keeps the doctor away”, addressing the supposed health benefits of the fruit, has been traced to 19th-century Wales, where the original phrase was “Eat an apple on going to bed, and you’ll keep the doctor from earning his bread”. In the 19th century and early 20th, the phrase evolved to “an apple a day, no doctor to pay” and “an apple a day sends the doctor away”; the phrasing now commonly used was first recorded in 1922.

A large Fremont’s Cottonwood Offers shade and protection along the Pima Canyon Trail.
In the shade, a grapevine, offers a vain promise of grapes.
The cottonwood’s deep roots draw water from a mountain stream.
Native Americans in the Western United States and Mexico used parts of Frémont’s cottonwood variously for a medicine, in basket weaving, for tool making, and for musical instruments. The inner bark of Frémont’s cottonwood contains vitamin C and was chewed as an antiscorbutic – treatment for vitamin C deficiency. The bark and leaves could be used to make poultices to reduce inflammation or to treat wounds.
The Pima people of southern Arizona and northern Mexico lived along Sonoran Desert watercourses and used twigs from the tree in the fine and intricate baskets they wove. The Cahuilla people of southern California used the tree’s wood for tool making, the Pueblo peoples for drums, and the Lower Colorado River Quechan people in ritual cremations. The Hopi of Northeastern Arizona carve the root of the cottonwood to create kachina dolls.
Here are 8 flower bud growing from one cladode (pad). There is a 9th bud on a second cladode. What is interesting about these pads are the needle shadows. Although thin, each provides some protection from the sun.
Cactus Closeup
This delicate bud will develop into a flower and, then, into a cactus fruit (in spanish, tuna). The fruit retains those tiny spines, called glochids, which detach on the smallest contact. The pads are also covered with them.
Prickly pears are known for growing into thickets. The Cuban government created a “cactus curtain” of prickly pears around the Guantanamo naval base in the 1960’s, to prevent Cubans from escaping to refuge in the United States.
Cactus Flowers
Look closely at the anthers of these flowers. Each curls over when touched, depositing its pollen. The habit of prickly pears to grow together in thickets mean there are clusters of blossoms in springtime.
Like the previous year, spring 2022, though cold, is early. As I write this the peony blooms presented here, photographed May, 2021 are seeding. Every year, Pam and I marvel at the color. 2019 this peony was in full bloom only by the end of May, around Memorial Day.
These photographs were taken with a Canon EOS 5D Mark IV dslr, and the Canon EF 50 mm f/1.2L USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head. Color results from the Canon dslr are impressive. In prior years I favored shooting late evening in the shade with a slight underexposure. This year I experimented with full sunlight. I found a slight under exposure captured the plum – fine burgundy wine nature of this Japanese cultivar, “Shimadaijin,” planted in the 1970’s or 1980’s.
This set brings out the petal’s fiery nature. In the wild, woody (also called tree) peonies favored cliffs and scrub of western and central China, eastern Himalayas (southeastern Tibet).

By a happy accident our neighbor’s honeybees foraged the nectar and pollen of these newly opened blooms. The woody stems hold the profusion of large flowers each one erect. “Tree” is a misnomer as this plant is a shrub growing mid-thigh high. One of the classic ornamental genera of China, known there as moutan or hua wang “King of Flowers.”

We find boulders of crystalline rock, commonly derived from Adirondack sources, left behind on the surface of ablation moraine, in the Finger Lakes Region.
Cornell finds some and move them, maybe the case for this unremarked erratic found along the Allen Trail of FR Newman Arboretum.
Another enormous erratic, brought in from the Sixmile Creek valley, was carved into a seat as a memorial to Professor R.S. Tarr who deciphered much of the glacial history of the Finger Lakes Region. Find it at the southwest corner of McCraw Hall on the Cornell University Campus.
History (from wikipedia)
During the 18th century, erratics were deemed a major geological paradox. Geologists identify erratics by studying the rocks surrounding the position of the erratic and the rock of the erratic itself. Erratics were once considered evidence of a biblical flood, but in the 19th century scientists gradually came to accept that erratics pointed to an ice age in Earth’s past. Among others, the Swiss politician, jurist, theologian Bernhard Friedrich Kuhn [de] saw glaciers as a possible solution as early as 1788. However, the idea of ice ages and glaciation as a geological force took a while to be accepted. Ignaz Venetz (1788–1859), a Swiss engineer, naturalist and glaciologist was one of the first scientists to recognize glaciers as a major force in shaping the earth.
In the 19th century, many scientists came to favor erratics as evidence for the end of the Last Glacial Maximum (ice age) 10,000 years ago, rather than a flood. Geologists have suggested that landslides or rockfalls initially dropped the rocks on top of glacial ice. The glaciers continued to move, carrying the rocks with them. When the ice melted, the erratics were left in their present locations.
Charles Lyell’s Principles of Geology (v. 1, 1830) provided an early description of the erratic which is consistent with the modern understanding. Louis Agassiz was the first to scientifically propose that the Earth had been subject to a past ice age. In the same year, he was elected a foreign member of the Royal Swedish Academy of Sciences. Prior to this proposal, Goethe, de Saussure, Venetz, Jean de Charpentier, Karl Friedrich Schimper and others had made the glaciers of the Alps the subjects of special study, and Goethe,[15] Charpentier as well as Schimper had even arrived at the conclusion that the erratic blocks of alpine rocks scattered over the slopes and summits of the Jura Mountains had been moved there by glaciers.
Charles Darwin published extensively on geologic phenomena including the distribution of erratic boulders. In his accounts written during the voyage of HMS Beagle, Darwin observed several large erratic boulders of notable size south of the Strait of Magellan, Tierra del Fuego and attributed them to ice rafting from Antarctica. Recent research suggests that they are more likely the result of glacial ice flows carrying the boulders to their current locations.

Betula papyrifera, common names Paper Birch, (American) White Birch, Canoe Birch, is a short-lived species of birch native to northern North America. Paper birch is named for the tree’s thin white bark, which often peels in paper like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes and is an important species for moose browsing. The primary commercial uses for paper birch wood are boltwood and sawlogs, while secondary products include firewood and pulpwood. It is the provincial tree of Saskatchewan and the state tree of New Hampshire.
As you can see in the following photoghraph, Betula papyrifera is a medium-sized deciduous tree typically reaching 20 meters (66 feet) tall, and exceptionally to 40 m (130 ft) with a trunk up to 75 centimeters (30 inches) in diameter. Within forests, it often grows with a single trunk but when grown as a landscape tree it may develop multiple trunks or branch close to the ground.
Paper birch is a typically short-lived species. It handles heat and humidity poorly and may live only 30 years in zones six and up, while trees in colder-climate regions can grow for more than 100 years. Betula papyrifera will grow in many soil types, from steep rocky outcrops to flat muskegs of the boreal forest. Best growth occurs in deeper, well drained to dry soils, depending on the location.
White Birch is a pioneer species, meaning it is often one of the first trees to grow in an area after other trees are removed by some sort of disturbance. Typical disturbances colonized by paper birch are wildfire, avalanche, or windthrow areas where the wind has blown down all trees. When it grows in these pioneer, or early successional, woodlands, it often forms stands of trees where it is the only species, a feature emulated in this Cornell Botanical Garden planting. Paper Birch is considered well adapted to fires because it recovers quickly by means of reseeding the area or regrowth from the burned tree. The lightweight seeds are easily carried by the wind to burned areas, where they quickly germinate and grow into new trees. Paper birch is adapted to ecosystems where fires occur every 50 to 150 years for example, it is frequently an early invader after fire in black spruce boreal forests. As paper birch is a pioneer species, finding it within mature or climax forests is rare because it will be overcome by trees that are more shade tolerant as secondary succession progresses.
For example, in Alaskan boreal forests, a paper birch stand 20 years after a fire may have 3,000–6,000 trees per acre (7,400–14,800/ha), but after 60 to 90 years, the number of trees will decrease to 500–800 trees per acre (1,200–2,000/ha) as spruce replaces the birch. After approximately 75 years, the birch will start dying and by 125 years, most paper birch will have disappeared unless another fire burns the area.
Paper birch trees themselves have varied reactions to wildfire. A group, or stand, of paper birch is not particularly flammable. The canopy often has a high moisture content, the understory is often lush green. As such, conifer crown fires often stop once they reach a stand of paper birch or become slower-moving ground fires. Since these stands are fire-resistant, they may become seed trees to reseed the area around them that was burned. However, in dry periods, paper birch is flammable and will burn rapidly. As the bark is flammable, it often will burn and may girdle the tree.

It handles heat and humidity poorly and may live only 30 years in zones six and up, while trees in colder-climate regions can grow for more than 100 years. Betula papyrifera will grow in many soil types, from steep rocky outcrops to flat muskegs of the boreal forest. Best growth occurs in deeper, well drained to dry soils, depending on the location.
In older trees, the bark is white, commonly brightly so, flaking in fine horizontal strips to reveal a pinkish or salmon-colored inner bark. It often has small black marks and scars. In individuals younger than five years, the bark appears a brown-red color with white lenticels, making the tree much harder to distinguish from other birches. The bark is highly weather-resistant. It has a high oil content; this gives it its waterproof and weather-resistant characteristics. Often, the wood of a downed paper birch will rot away, leaving the hollow bark intact.
Birch bark is a winter staple food for moose. The nutritional quality is poor because of the large quantities of lignin, which makes digestion difficult, but is important to wintering moose because of its sheer abundance. Moose prefer paper birch over aspen, alder, and balsam poplar, but they prefer willow (Salix spp.) over birch and the other species listed. Although moose consume large amounts of paper birch in the winter, if they were to eat only paper birch, they may starve.
Although white-tailed deer consider birch a “secondary-choice food,” it is an important dietary component. In Minnesota, white-tailed deer eat considerable amounts of paper birch leaves in the fall. Snowshoe hares browse paper birch seedlings, and grouse eat the buds.
Porcupines and beavers feed on the inner bark. The seeds of paper birch are an important part of the diet of many birds and small mammals, including chickadees, redpolls, voles, and ruffed grouse. Yellow bellied sapsuckers drill holes in the bark of paper birch to get at the sap; this is one of their favorite trees for feeding on. As a species, Birches are commonly cultivated as fast-growing, graceful trees with ornamental bark.
The wood of Betula pendulas Roth. Is light and an excellent thermal insulator, so is used for the inside of saunas in Finland. The wood of Betula alleghaniensis is use for furniture, paneling, and plywood in North America.
Birch sap, collected in spring when it pours from the tree, can be used to make beer. Various species have been used medicinally, and Betula lenta was used as a source of oil of wintergreen, or methyl salicylate; American Indians used it to treat many ailments. Betulinic acid from the bark is reported to trigger cell death in melanomas in culture.
The bark of B papyrifera Marsh. Is waterproof and used for birch-bark canoes by American Indians, as well as for roofing in some parts of the world. Several species were used as paper, including Betula utilis, which has been found in the form of 1800-year-old Buddhist manuscripts in Afghanistan.

Acer rubrum is one of the most abundant and widespread trees in eastern North America. It can be found from the south of Newfoundland, through Nova Scotia, New Brunswick, and southern Quebec to the southwest west of Ontario, extreme southeastern Manitoba and northern Minnesota; southward through Wisconsin, Illinois, Missouri, eastern Oklahoma, and eastern Texas in its western range; and east to Florida. It has the largest continuous range along the North American Atlantic Coast of any tree that occurs in Florida. In total it ranges 2,600 km (1,600 mi) from north to south. The species is native to all regions of the United States east of the 95th meridian. The tree’s range ends where the −40 °C (−40 °F) mean minimum isotherm begins, namely in southeastern Canada. A. rubrum is not present in most of the Prairie Peninsula of the northern Midwest (although it is found in Ohio), the coastal prairie in southern Louisiana and southeastern Texas and the swamp prairie of the Florida Everglades. Red maple’s western range stops with the Great Plains where conditions become too dry for it. The absence of red maple from the Prairie Peninsula is most likely due to the tree’s poor tolerance of wildfires. Red maple is most abundant in the Northeastern US, the Upper Peninsula of Michigan, and northeastern Wisconsin, and is rare in the extreme west of its range and in the Southeastern US.
On the arboretum northeast side is a collection of native maples, this Red Maple is represented caught our eye.
These metal tags are excellent signposts hanging from the branches on coated wire. Red maple’s maximum lifespan is 150 years, but most live less than 100 years. The tree’s thin bark is easily damaged from ice and storms, animals, and when used in landscaping, being struck by flying debris from lawn mowers, allowing fungi to penetrate and cause heart rot.[8] Its ability to thrive in many habitats is largely due to its ability to produce roots to suit its site from a young age. In wet locations, red maple seedlings produce short taproots with long, well-developed lateral roots; while on dry sites, they develop long taproots with significantly shorter laterals. The roots are primarily horizontal, however, forming in the upper 25 cm (9.8 in) of the ground. Mature trees have woody roots up to 25 m (82 ft) long. They are very tolerant of flooding, with one study showing that 60 days of flooding caused no leaf damage. At the same time, they are tolerant of drought due to their ability to stop growing under dry conditions by then producing a second-growth flush when conditions later improve, even if growth has stopped for 2 weeks.
Acer rubrum is one of the first plants to flower in spring. A crop of seeds is generally produced every year with a bumper crop often occurring every second year. A single tree between 5 and 20 cm (2.0 and 7.9 in) in diameter can produce between 12,000 and 91,000 seeds in a season. A tree 30 cm (0.98 ft) in diameter was shown to produce nearly a million seeds. Red maple produces one of the smallest seeds of any of the maples. Fertilization has also been shown to significantly increase the seed yield for up to two years after application. The flowers are generally unisexual, with male and female flowers appearing in separate sessile clusters, though they are sometimes also bisexual. These pistillate (female) flowers have one pistil formed from two fused carpels with a glabrous superior ovary and two long styles that protrude beyond the perianth. These flowers were formed on the tree labeled “Frank’s Red.”
These staminate (male) flowers are sessile (grow direct from tip of branch without a stalk) containing between 4 and 12 stamens, often with 8. These seem to have 12 stamens.
The above flowers were formed on a “Schlesinger I” Red Maple Tree (see following lable).

After spreading 15,000 square feet of crabcrass/fertilizer and before attending a frigid first baseball game of a grandson, I capture eight photographs of five different flowers from our home.
More about the Magnolia, from Wikipedia: The name Magnolia first appeared in 1703 in the Genera of Charles Plumier (1646–1704), for a flowering tree from the island of Martinique (talauma). It was named after the French botanist Pierre Magnol.
More about the Hydrangea, from Wikipedia: Hydrangea is derived from Greek and means ‘water vessel’ (from ὕδωρ húdōr “water” + ἄγγος ángos or αγγεῖον angeîon “vessel”), in reference to the shape of its seed capsules.
More about these Quince, from Wikipedia: Although all quince species have flowers, gardeners in the West often refer to these species as “flowering quince”, since Chaenomeles are grown ornamentally for their flowers, not for their fruits.
More about Forsythia, from Wikipedia: The genus is named after William Forsyth (1737–1804), a Scottish botanist who was a royal head gardener and a founding member of the Royal Horticultural Society.
More about Forsythia, from Wikipedia: Narcissus is a genus of predominantly spring flowering perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil, narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting colored tepals and corona.

I read the New York Times on our porch on a spring Sunday afternoon, taking a moment to capture these fair weather cumulus clouds. Visible are Ithaca’s East Hill, downtown, and a forsythia bush in flower.
More about the flowers, from Wikipedia: Forsythias are popular early spring flowering shrubs in gardens and parks, especially during Eastertide; Forsythias are nicknamed the “Easter Tree”, the symbol of the coming spring.
More about this view, from Wikipedia: Cumulus clouds can form in lines stretching over 480 kilometers (300 mi) long called cloud streets. These cloud streets cover vast areas and may be broken or continuous. They form when wind shear causes horizontal circulation in the atmosphere, producing the long, tubular cloud streets. They generally form during high-pressure systems, such as after a cold front.
