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 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.”

Treman Early Autumn Walk IX
The post discusses various unique kennings, their meanings, and reflects on the term “Swan-Road” symbolizing a serene river.
Below Lucifer Falls this quiet water flows beneath a bridge linking Gorge and Rim trails. The reflection of blue sky between river trees brings to mind the kenning “Swan-Road.” To me it is more fitting than the established meaning: “The Sea,” also associated more appropriately with Whale-Road.
The seldom used English verb “ken.” The Oxford English dictionary proposed the word was borrowed from Norse based on a confluence of meaning, i.e. to know. When it is turned into a noun with the -ing ending, it is a phrase that brings to mind and object described.
Other kennings from : “Whale road = sea (e.g., a place where whales travel); Treasure seat = throne (e.g., the source of treasure or reward, or the role of the king in rewarding his men); Ring giver, ring breaker = king (e.g., the person who bestows rings, or breaks off a piece of his golden bracelet as a reward); Sword sleep = death (e.g., a “sleep” caused by a sword wound); Rapture of heaven = sun (e.g., the sun, brightest of heavenly objects, the joy of heaven); Weaver of peace = wife (e.g., a person whose grace and mildness instills peace, or one who creates domestic tranquility); Earl’s defense = Beowulf (e.g., the one who defends Hrothgar); Mead seats = benches in Heorot (e.g., the places where people sit and drink).”

Treman Early Autumn Walk VII
Unnamed though memorable
An unnamed waterfall along the Gorge Trail is memorable for the steps alongside.
I have captured it in all seasons from the beginning of my photography interest. Here it is at midday, early autumn, 2023, taken with the Apple Iphone 14 proMax. Bright sunlight ruins the shot.
Here, evening, early summer 2003, the foreground shaded, late day sunlight on trees beyond. The Sony dsc F828 camera, on a tripod, was used.
Here, bright sunlight at midday is handled by framing the brightly lit waterfall, April, 2002. A handheld Sony Mavica was used.
Daring visitors jump from the wall at right into a plunge pool, seen here as the quiet water at base of wall. It is a doubly dangerous activity as the force of water can hold a swimmer under indefinitely, missing the narrow pool results in striking the rocks. Robert H. Treman New York State Park, Tompkins County, Ithaca, New York.
“Plunge pools are formed by the natural force of falling water, such as at a waterfall or cascade; they also result from man-made structures such as some spillway designs. Plunge pools are often very deep, generally related to the height of fall, the volume of water, the resistance of the rock below the pool and other factors.[4] The impacting and swirling water, sometimes carrying rocks within it, abrades the riverbed into a basin, which often features rough and irregular sides. Plunge pools can remain long after the waterfall has ceased flow or the stream has been diverted. Several examples of former plunge pools exist at Dry Falls in the Channeled Scablands of eastern Washington. They can also be found underwater in areas that were formerly above sea level, for example Perth Canyon off the coast of Western Australia.”
“Plunge pools are fluvial features of erosion which occur in the youthful stage of river development, characterized by steeper gradients and faster water flows. Where softer or fractured rock has been eroded back to a knickpoint, water continues to bombard its base. Because this rock is often less resistant than overlying strata, the water from the higher elevation continues eroding downward until an equilibrium is achieved.”

Treman Early Autumn Walk VI
Fairy Forest
Over a period of 11,000 years this former stream bed, abandoned when a melting tongue of the Laurentide Ice Sheet deposited drift across Enfield Creek, transformed to this sun dappled glade, one of two along the Gorge Trail of Treman Park.
Pam calls this the Fairy Forest for the feeling of peaceful expectation she feels here. Another reason is the small flowers of this native myrtle after which the periwinkle is named.
Fallen trees are left be to return to the soil.
“Vinca minor (common names lesser periwinkle, dwarf periwinkle is a species of flowering plant in the dogbane family, native to central and southern Europe, from Portugal and France north to the Netherlands and the Baltic States, east to the Caucasus, and also southwestern Asia in Turkey. Other vernacular names used in cultivation include small periwinkle, common periwinkle, and sometimes in the United States, myrtle or creeping myrtle.”
“Vinca minor is a trailing subshrub, spreading along the ground and rooting along the stems to form large clonal colonies and occasionally scrambling up to 40 centimeters (16 in) high but never twining or climbing. The leaves are evergreen, opposite, 2–4.5 centimeters (0.79–1.77 in) long and 1–2.5 centimeters (0.39–0.98 in) broad, glossy dark green with a leathery texture and an entire margin.“
“The flowers are solitary in the leaf axils and are produced mainly from early spring to mid-summer but with a few flowers still produced into the autumn; they are violet-purple (pale purple or white in some cultivated selections), 2–3 centimeters (0.79–1.18 in) diameter, with a five-lobed corolla. The fruit is a pair of follicles 2.5 centimeters (0.98 in) long, containing numerous seeds.”
“The species is commonly grown as a groundcover in temperate gardens for its evergreen foliage, spring and summer flowers, ease of culture, and dense habit that smothers most weeds.”
“Vinca minor contains more than 50 alkaloids, including vincamine. Other alkaloids include reserpine, rescinnamine, akuammicine, majdine, vinerine, ervine, vineridine, tombozine, vincamajine, vincanine, vincanidine, vinburnine, apovincamine, vincaminol, desoxyvincaminol, vincorine[ and perivincine. Vinpocetine (brand names: Cavinton, Intelectol; chemical name: ethyl apovincaminate) is a semisynthetic derivative alkaloid of vincamine.”
It is possible this is a cemetery as myrtle was once commonly planted in cemeteries in parts of the United States and naturalized periwinkle may indicate the presence of graves whose other markers have disappeared.

Treman Early Autumn Walk V
a drift filled stream bed
Wisconsin Glacial Episode was only the latest of a series of ice wall incursions. For this walk I went off the path to bushwack, following a drift filled stream bed, evidence of multiple glacial incursions with subsequent changing the stream bed of Enfield Creek. Here I am walking on glacial deposition to the north of the current creek bed. A park ranger informed us of this location, it is difficult to comprehend or imaging a 50 foot hill of material deposited in this way. The creek does bend at this point and the deposition is easily seen from above.
The surface of the hill is hummocky, typical of glacial deposition.
Eventually the former stream bed intersects with a work road sloping back down to the Gorge Trail. It was here I found the oak apple gall of yesterday’s posting.

Cultivated vs Wild
“Dennstaedtia punctilobula, the eastern hayscented fern or hay-scented fern, is a species of fern native to eastern North America, from Newfoundland west to Wisconsin and Arkansas, and south in the Appalachian Mountains to northern Alabama; it is most abundant in the east of its range, with only scattered populations in the west.”
“It is a deciduous fern with fronds growing to 40–100 cm (rarely 130 cm) tall and 10–30 cm broad; the fronds are bipinnate, with pinnatifid pinnules about three times as long as broad. It occurs in damp or dry acidic soils in woods or open woods, from sea level up to 1,200 m altitude.”
“Dennstaedtia punctilobula can exhibit varying degrees of phototropism. The common name “Hay-scented Fern” comes from the fact that crushing it produces an aroma of fresh hay.“
“The presence of D. punctilobula influences the dynamics of the understory vegetation of many forests in the eastern United States. An abundance of highbush blackberry (Rubus allegheniensis) in open areas encourages new tree seedlings. Where the effects of herbivorous animals (such as deer) reduce the abundance of R. allegheniensis, D. punctilobula, which is not browsed by deer, takes over. Where D. punctilobula becomes common, the growth of tree seedlings is restricted.”

Cultivated vs Wild
Today I walked the Gorge Trail to below Lucifer Falls, crossed the bridge and returned via the South Rim Trail, a trip of over 5 miles according to the Apple IPhone 14 Pro Max used for these photographs.
Thankful I was not here when this tree gave way across the trail.
