Observation Date: 6/23/19
Observation Time: 10:45 a.m.
Observation Location: Billings Loop Botanical Trail
Common Name: Indian Pipe
Scientific Name: Monotropa uniflora
Comments: Indian pipe, also known as ghost plant (or ghost pipe) or corpse plant, is a herbaceous perennial plant native to temperate regions of European Russia, Asia, North America and northern South America, but with large gaps between areas. It is generally rare in occurrence.
Unlike most plants, it is white and does not contain chlorophyll. Instead of generating energy from sunlight, it is parasitic, more specifically a myco-heterotroph. Its hosts are certain fungi that are mycorrhizal with trees, meaning it ultimately gets its energy from photosynthetic trees. Since it is not dependent on sunlight to grow, it can grow in very dark environments as in the understory of dense forest. It is often associated with beech trees. The complex relationship that allows this plant to grow also makes propagation difficult.

Observation Location: Moose Hill Farm (TTOR)
Common Name: Interrupted fern
Scientific Name: Osmunda claytonia
Comments: The species name (claytoniana) is a tribute to John Clayton, an 18th century botanist and one of the earliest collectors of plant specimens in what later became the Commonwealth of Virginia.
The common name (Interrupted Fern) is a reference to the fact that the blade of fertile fronds is interrupted by several fertile leaflets in the midsection. Early sources refer to this fern as Clayton’s Fern.

Observation Location: Moose Hill Audubon Wildlife Sanctuary
Common Name: Jack-in-the-pulpit
Scientific Name: Arisaema triphyllum
Comments: Jack-in-the-pulpits grow in largely deciduous forests with plenty of shade. They prefer rich, moist soil and can often be found near wetlands and vernal pools.
In the late summer, after the plant’s flower has been pollinated, it produces a large clump of bright red berries. Each berry contains several seeds, which are spread by birds and other small animals after ingestion.
The plant’s leaves, berries, and corms contain calcium oxalate, which is a chemical compound that takes the form of tiny crystalline structures. Getting this on your bare skin can cause irritation, and ingesting the plant raw can be dangerous, sometimes resulting in choking or blisters. It is therefore recommended to avoid touching any part of the plant unless you’re wearing gloves and other skin protection.
Please do not dig up wildflowers. Leave them for others to enjoy.

Observation Time: 3:15 p.m.
Observation Location: end of Lee Road
Common Name: Japanese Barberry
Scientific Name: Berberis thunbergii
Comments: This specimen was a few yards beyond the end of Lee Road near the Atlantic White Cedar Swamp drainage ditch. Japanese barberry is often planted for hedges, and easily spreads to natural areas, as this specimen evidently did.
“In recent years the plant has been recognized as an invasive species in parts of the eastern United States; it is avoided by deer and has been replacing native species. Further, the plant raises the pH of the soil and affects its nitrogen levels. In Canada its cultivation is prohibited as the species can act as a host for Puccinia graminis (black rust), a rust disease of wheat. Currently there are breeding and selection programs aimed at producing cultivars that are either sterile or produce relatively little seed.” Wikipedia

Observation Location: Gavins Pond Road near soccer fields
Common Name: Jerusalem Artichoke
Scientific Name: Helianthus tuberosus
Comments: Before the arrival of Europeans, Native Americans cultivated H. tuberosus as a food source. The tubers persist for years after being planted, so that the species expanded its range from central North America to the eastern and western regions. Early European colonists learned of this, and sent tubers back to Europe, where it became a popular crop and naturalized there. It later gradually fell into obscurity in North America, but attempts to market it commercially have been successful in the late 1900s and early 2000s.
The tuber contains about 2% protein, no oil, and little starch. It is rich in the carbohydrate inulin (8 to 13%), which is a polmer of the monosaccharide fructose. Tubers stored for any length of time convert their inulin into its component fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times as sweet as sucrose.
It has also been reported as a folk remedy for diabetes : since inulin is not assimilated in the intestine, it doesn’t cause a glycemic spike as potatoes would. Temperature variances have been shown to affect the amount of inulin the Jerusalem artichoke can produce. It makes less inulin in a colder region than when it is in a warmer region.

Observation Location: 4 Gavins Pond Road
Common Name: Lingzhi mushroom
Scientific Name: Ganoderma tsugae
Comments: This mushroom specimen was growing in the tamarack (larch) grove in my back yard. It is probably growing on a root, as it was growing on the ground right next to a big tamarack tree. Since tamaracks are coniferous, this specimen is presumably Ganoderma tsugae, rather than Ganoderma lucidum, which grows on deciduous trees.
Apparently, these mushrooms are valued for their medicinal properties.

Common Name: Milkweed
Scientific Name: Asclepias syriaca
Comments: Monarch butterflies depend on milkweed as a food source for their caterpillars. The advent of genetically modified “Roundup-ready” corn and soybeans has facilitated large-scale application of herbicides, reducing the availability of milkweed to migrating monarchs. Hence, the monarch population is in steep decline. Homeowners wanting to help monarchs can inadvertently hurt them by planting the wrong kind of milkweed (Ophryocystis elektroscirrha). Unfortunately, native milkweed that monarchs need is harder to propagate.

Common Name: Mulberry tree
Scientific Name: Morus (family)
Comments: Mulberry is a tree belonging to the Moraceae family (also including the fig, jackfruit, and other fruits). Generally, the genus has 64 subordinate taxa, three of which are well-known and are ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry (Morus alba, M. rubra, and M. nigra, respectively). M. alba is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. M. alba is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States.
The taxonomy of Morus is complex and disputed. Fossils of Morus appear in the Pliocene record of the Netherlands Over 150 species names have been published, and although differing sources may cite different selections of accepted names, less than 20 are accepted by the vast majority of botanical authorities. Morus classification is even further complicated by widespread hybridisation.

Common Name: Old Man’s Beard lichen
Scientific Name: Usnea strigosa
Comments: Also called bushy beard, this epiphytic (i.e. growing on trees) lichen is a composite organism that emerges from algae or cyanobacteria living among the filaments of the fungi in a symbiotic (mutually beneficial) relationship. The fungi benefit from the carbohydrates produced by the algae or cyanobacteria via photosynthesis. The algae or cyanobacteria benefit by being protected from the environment by the filaments of the fungi, which also gather moisture and nutrients from the environment, and (usually) provide an anchor to it.

Observation Location: 4 Gavins Pond Rd.
Common Name: Peony
Scientific Name: Paeonia spp.
Comments: Long ago, some observant gardener noticed that ants on peony buds always meant the flowers would open soon. And so a bit of folk wisdom was born: Peonies cannot open until ants eat away the seal that keeps the buds closed. But it isn’t true. The thing the ants are eating is nectar, not glue, and what this does for the peony is make sure there are plenty of ants around to eat any soft-bodied insects that might like to eat peonies.

Observation Location: Moose Hill Farm (TTOR)
Common Name: Poison Ivy
Scientific Name: Toxicodendron radicans
Comments: Everyone should learn to identify poison ivy and avoid contact with its glossy, notched leaves. As both its common name and its scientific name suggest, the triplicate leaves of this plant can cause an intensely itchy rash that lasts for weeks. Jewelweed, which often grows near poison ivy, is also an antidote for poison ivy.
Poison ivy is often seen in disturbed areas along roads and paths, but it can also climb up trees as a thick vine. When ripe, the white fruits are a favorite food of many migrant and game birds, as well as white-tailed deer. The seeds are adapted for sprouting after digestion softens the seed coat.
