Among Fallen Leaves

The red berries of the Jack-in-the-Pulpit plant play a key role in seed dispersion, wildlife sustenance, and fueling its energy storage organ, the corm.

As the crisp air of autumn settles in and the leaves begin their spectacular transformation into hues of red, orange, and yellow, the forest floor comes alive with a myriad of hidden wonders. Among these wonders, the Jack-in-the-Pulpit (Arisaema triphyllum) stands out for its striking red berries and the role they play in the fall glory of the woodland ecosystem. In this essay, we will explore the beauty and significance of these red berries and how they are intrinsically linked to the plant’s corm.

The Jack-in-the-Pulpit, a native perennial herbaceous plant of North America, is known for its distinctive appearance, featuring a hood-like structure known as the spathe and a tall, slender stalk called the spadix. It is during the fall season that the plant’s fascinating red berries make their appearance, contrasting vividly against the backdrop of autumn’s colors. These berries are the result of a process that begins in the spring, when the plant first emerges from its underground corm.

Throughout the growing season, the Jack-in-the-Pulpit devotes its energy to producing these striking red berries, which serve several important ecological functions. The red berries are not only visually appealing but also function as a means of reproduction for the plant. They contain seeds that, once mature, can be dispersed to establish new Jack-in-the-Pulpit plants. These seeds are often transported by animals that consume the berries, such as birds and rodents, which then disperse them in their droppings, contributing to the plant’s spread throughout the forest.

The bright red color of the berries is a key feature that attracts birds, making them an essential food source during the fall and early winter months. Birds like thrushes, cardinals, and robins are known to feed on the Jack-in-the-Pulpit berries, aiding in seed dispersal while benefiting from the nutrient-rich fruits. This mutualistic relationship between the plant and its avian dispersers showcases the interconnectedness of the forest ecosystem, where each species relies on the other for survival and propagation.

The significance of the Jack-in-the-Pulpit’s red berries extends to the corm beneath the surface. The corm serves as an energy storage organ for the plant, helping it survive through the harsh winter months when the above-ground parts of the plant wither and die. During the fall, as the plant directs its energy toward producing berries, it also transfers nutrients to the corm, ensuring its vitality and readiness for the following spring.

Furthermore, the corm itself can serve as an energy reserve for the production of future berries and the growth of new shoots. As the plant enters dormancy, it relies on the stored energy in the corm to fuel its growth when conditions become favorable in the next growing season. In this way, the corm and the red berries are intricately linked, with the berries representing the culmination of a year-long process of energy accumulation and reproduction.

In conclusion, the red berries of the Jack-in-the-Pulpit are a captivating and vital component of the fall glory that graces our woodlands. Their vibrant color and ecological role in seed dispersal highlight the plant’s contribution to the forest ecosystem’s richness and diversity. Moreover, these berries are a testament to the interconnectedness of nature, as they are not only visually stunning but also an essential food source for wildlife. As we marvel at the beauty of fall and explore the wonders of the natural world, let us take a moment to appreciate the significance of the red berries of the Jack-in-the-Pulpit and their role in the intricate web of life that surrounds us.

ScienceCenter with Grandchildren

The ScienceCenter museum encourages learning about nanotechnology’s prevalence and unpredictable, unique behaviors.

Our day of science began with measurement: each grandchild’s growth is represented on this corner. Even as young adults they visit and are re-measured. Here Rory is making his mark.

Our science inspired museum, ScienceCenter, is full of fun activities.

Nothing like touching a space object: an iron-nickel meteorite.

So much to learn and discover. Here is Sam perusing a “nano” display.

Nanotechnology is pervasive, existing both in nature and within our technological innovations. Nature offers numerous instances of nanoscale phenomena. For instance, the iridescent hues seen in certain butterflies and the adhesive properties of geckos’ feet are both outcomes of nanostructures.

In our everyday products, nanotechnology plays a significant role. You’ll find it in items you use regularly, such as computer chips featuring minuscule nano-sized components and sunscreen containing nanoparticles. Looking ahead, nanotechnology will play an even more prominent role in our lives.

The question is: Where can you spot the influence of nanotechnology in your own life?

Materials exhibit distinct behaviors at the nanoscale. Tiny particles of gold appear red or purple, as opposed to their conventional shiny, golden appearance. When nanoparticles of iron are dispersed in a liquid, they give rise to a remarkable substance known as ferrofluid, which is a liquid that exhibits a magnetic attraction.

The nanoscale realm also harbors other surprising phenomena. Here, different physical forces dominate, leading to unexpected behaviors. For instance, at nanoscale the force of gravity becomes nearly imperceptible, while static electricity exerts a much greater influence.

Scientists are actively exploring ways to harness these unique nanoscale properties in the development of novel materials and cutting-edge technologies.

Nanotechnology enables us to construct structures much like nature does: atom by atom. Everything in the world is composed of “building blocks” known as atoms. In nature, varied combinations of atoms create diverse materials. For instance, diamond, graphite, and carbon nanotubes are all composed entirely of carbon atoms, but their unique properties emerge from the distinct arrangements of these carbon atoms.

In the field of nanotechnology, we are gaining the knowledge and capability to craft small, functional objects from individual atoms. Remarkably, some new nanomaterials have the capacity to self-assemble, opening up new possibilities for nanotechnology.

Baker Lab with Autumn Trees

Double Irony

Baker Lab

Baker Laboratory dates back to World War I.  With 200,000 square feet of space, the lab is home to Cornell’s Chemistry and Chemical Biology Department, the Chemistry Research Computing Facility, the Nuclear Magnetic Resonance Facility, and the Advanced ESR Technology Research Center (whew!!).

Trees on a Knoll

On the right, on a knoll, is a European beech tree (Fagus sylvatica).  The Latin name holds a double irony. Standing, alone, high above East Avenue on the Cornell campus  (sylvatica means “of forests”) as a memory of the forests growing above Cayuga Lake is a being once worshiped as a god.   In Celtic mythology, Fagus is the god of beeches.

A maple is on the left, genus Acer of unknown species.  I recognize it from the shape.

Red Maple (Acer Rubrum)

The Red Maple (Acer Rubrum) is tolerant of diverse conditions, making it a perfect choice for this  spot on the short of Beebe Lake.

Maple Syrup

Even though it is not a “Sugar Maple, early spring, the sap can be boiled down to syrup.

Turning Tree

The first to flower in spring and the first to turn in autumn.

From the Top Down

This maple turns from the top down and is already bare for most top branches.

Lib Slope Hickory

the largest and brightest yellow canopy on Libe Slope.

Libe Slope

Cornell University is on a west-facing hill above Cayuga lake.  Libe Slope is between the West Campus and Quadrangle / Libraries.

Besides the exercise of walking the 18 degree incline several times each day,  Cornell students and alumni remember The Slope for autumn color.

Built in 1868, McGraw Hall has the honor of having the first of Cornell’s towers. The building is built of Ithaca stone and is home to the American Studies Program, Department of History, Department of Anthropology, and Archaeology Intercollege Program. The first floor of McGraw Hall houses the McGraw Hall Museum, a collection of roughly 20,000 objects from around the globe used for teaching by the Anthropology Department.

Hickory

This is a Pignut Hickory (Carya glabra),  the largest tree  according to a 2009 Campus Tree Inventory (see link, below).

Seen from the north on a cloudy October day, this Pignut Hickory (Carya glabra) is the largest tree on the Cornell Campus, at 79 inches in diameter.

This hickory grows south of the Johnson Museum and among the autumn glories, it is the largest and brightest yellow canopy on Libe Slope.

Contrast

I remember this hickory for the contrast between the canopy and trunk, the way the clumps of yellow hang from dark boughs.  An overcast day is the best to capture this spectacle.  October 20, 2012 provided both bright sun and dark, rolling autumn clouds.  I waited on the north side, sheltered from the glare of the sky, for these perfect moments.

Leaves and Nuts

The pignut hickory is native to these Eastern United States.  It is known to favor moist slopes and this specimen has thrived on The Slope.  The ground beneath it is thick with nuts.

One week later as Hurricane Sandy approached the east coast

Just one week later, late afternoon on a sunny Friday as hurricane Sandy approached the east coast the hickory has fewer, tawny golden leaves.

Later in October the bright yellow leaves of the Libe Slope Hickory darken to a tawny gold. The Johnson Museum is in the right background.

Wonderful Flow of Limbs among Gold

Seen from the north on a cloudy October day, this Pignut Hickory (Carya glabra) is the largest tree on the Cornell Campus, at 79 inches in diameter.

Newgrange VIII

The Newgrange facade and kerbstones consists of stones from various locations, believed to be transported by sea and river.

The Newgrange façade and entrance of today is a creation from the large quantity of small stones unearthed and conserved during excavation given form by a steel-reinforced concrete retention wall. 

The brilliant white quartz cobblestones were collected from the Wicklow Mountains, 31 miles to the south.  Our guide called them “sunstones” for the way they reflect sunlight. In the following photograph is white quartz, the same excavated 1967-1975 from the Newgrange site and incorporated into the facade, I collected from “Miners Way” along R756 (above Glendalough).

You can also see in these photographs dark rounded granodiorite cobbles from the Mourne Mountains, 31 miles to the north.  Dark gabbro cobbles from the Cooley Mountains and banded siltstone from the shore at Carlingford Lough both locations on the Cooley Peninsula where my mother’s family still has farms.

The stones may have been transported to Newgrange by sea and up the River Boyne by fastening them to the underside of boats at low tide. None of the structural slabs were quarried, for they show signs of having been weathered naturally, so they must have been collected and then transported, largely uphill, to the Newgrange site. The granite basins found inside the chambers also came from the Mournes.

Geological analysis indicates that the thousands of pebbles that make up the cairn, which together would have weighed about 200,000 tons, came from the nearby river terraces of the Boyne. There is a large pond in this area that is believed to be the site quarried for the pebbles by the builders of Newgrange.

Most of the 547 slabs that make up the inner passage, chambers, and the outer kerbstones are greywacke. Some or all of them may have been brought from sites either 3 miles away or from the rocky beach at Clogherhead, County Louth, about 12 miles to the northeast.

Treman Early Autumn Walk XIV

The post discusses the Hepatica acutiloba plant, highlighting its characteristics, growth, historical medicinal use, and its natural habitat in central eastern North America. It also includes an observation made in Robert H. Treman Park.

These characteristic leaves are Hepatica plants growing on the sun dappled southern rim of Robert H. Treman Park captured on a bright late September morning.

“Hepatica acutiloba, the sharp-lobed hepatica, is a herbaceous flowering plant in the buttercup family Ranunculaceae. It is sometimes considered part of the genus Anemone, as Anemone acutiloba, A. hepatica, or A. nobilis. Also generally known as Liverleaf and Liverwort.”


“The word hepatica derives from the Greek ἡπατικός hēpatikós, from ἧπαρ hêpar ‘liver’, because its three-lobed leaf was thought to resemble the human liver.”


“Each clump-forming plant grows 5 to 19 cm (2.0 to 7.5 in) tall, flowering in the early to mid spring. The flowers are greenish-white, white, purple or pinkish in color, with a rounded shape. After flowering the fruits are produced in small, rounded columned heads, on pedicels 1 to 4 mm long. When the fruits, called achenes, are ripe they are ovoid in shape, 3.5–4.7 mm long and 1.3–1.9 mm wide, slightly winged and tend to lack a beak.”

Hepatica Flowers in early spring on the Rim Trail

“Hepatica acutiloba is native to central eastern North America where it can be found growing in deciduous open woods, most often in calcareous soils. Butterflies, moths, bees, flies and beetles are known pollinators. The leaves are basal, leathery, and usually three-lobed, remaining over winter.”

“Hepatica was once used as a medicinal herb. Owing to the doctrine of signatures, the plant was once thought to be an effective treatment for liver disorders. Although poisonous in large doses, the leaves and flowers may be used as an astringent, as a demulcent for slow-healing injuries, and as a diuretic.”

Treman Early Autumn Walk XIII

The Red Pine, Minnesota’s state tree, is a tall, conical, long-lived evergreen with distinctive orange-red bark.

Returning from a Rim Trail walk one April my boots were yellow from a prolific release of pollen from flowers of these tall trees that develop into the woody cones.

Pinus, the pine, is the largest genus in the family Pinaceae, with around 100 species throughout the northern hemisphere.


Red Pine (Pinus resinosa) is Minnesota’s state tree, known there as the Norway Pine. The use of the name “Norway” may stem from early Scandinavian immigrants who likened the American red pines to the Scots pines back home.


“Red pine is a coniferous evergreen tree characterized by tall, straight growth. It usually ranges from 20–35 meters (66–115 feet) in height and 1 m (3 ft 3 in) in trunk diameter, exceptionally reaching 43.77 m (143+1⁄2 ft) tall. The crown is conical, becoming a narrow, rounded dome with age. The bark is thick and gray brown at the base of the tree, but thin, flaky and bright orange red in the upper crown; the tree’s name derives from this distinctive character. Some red color may be seen in the fissures of the bark. The species is self-pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.”


“It is a long-lived tree, reaching a maximum age of about 500 years. Another member of Pinus, Pinus longaeva D.K. Bailey, the intermountain bristlecone pine, is the longest-lived tree in the world; one in the White Mountains of Nevada is estimated to be 5,000 years old, and by matching rhe rings with even older dead trees, a sequence going back 8,500 years has been established.”

“Red pine is notable for its very constant morphology and low genetic variation throughout its range, suggesting it has been through a near extinction in its recent evolutionary history. A genetic study of nuclear microsatellite polymorphisms among populations distributed throughout its natural range found that red pine populations from Newfoundland are genetically distinct from most mainland populations, consistent with dispersal from different glacial refugia in this highly self-pollinating species.”
