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.

Common Name: Skunk Cabbage
Scientific Name: Symplocarpus foetidus
Comments: Skunk cabbages are among the first plants to emerge in early spring. They can maintain an internal temperature significantly warmer than the surrounding air – as much as 15-35 degrees warmer – by consuming carbohydrates stored in their fleshy rhizomes. The warmth they generate helps in attracting cold-blooded, early-emerging pollinating insects in early spring when temperatures are typically quite chilly.
More Information: National Park Service
Observer: Paul Lauenstein
Observation Date: 6/24/10
Observation Time: 3:40 p.m.
Observation Location: Beaver Brook near tennis courts
Common Name: Skunk cabbage
Scientific Name: Symplocarpus foetidus
Comments: Tearing a leaf produces a pungent but not harmful odor, the source of the plant’s common name; it is also foul smelling when it blooms. The plant is not poisonous to the touch. The foul odor attracts pollinators, such as scavenging flies, stoneflies, and bees. The odor in the leaves may also serve to discourage large animals from disturbing or damaging this plant which grows in soft wetland soils.
Eastern skunk cabbage is notable for its ability to generate temperatures of up to 15–35 °C (27–63 °F) above air temperature by cyanide resistant cellular respiration in order to melt its way through frozen ground, placing it among a small group of thermogenic plants. Even though it flowers while there is still snow and ice on the ground, it is successfully pollinated by early insects that also emerge at this time. Carrion-feeding insects that are attracted by the scent may be doubly encouraged to enter the spathe because it is warmer than the surrounding air, fueling pollination.
Eastern skunk cabbage has contractile roots which contract after growing into the earth. This pulls the stem of the plant deeper into the mud, so that the plant in effect grows downward, not upward. Each year, the plant grows deeper into the earth, so that older plants are practically impossible to dig up. They reproduce by hard, pea-sized seeds which fall in the mud and are carried away by animals or by floods.

Common Name: Spotted knapweed
Scientific Name: Centaurea maculosa
Comments: Knapweed is a pioneer species found in recently disturbed sites or openings. Once it has been established at a disturbed site, it continues to spread into the surrounding habitat. This species outcompetes natives through at least three methods:
- A tap root that sucks up water faster than the root systems of its neighbors,
- Quick spread through high seed production, and
- Low palatability, meaning it is less likely to be chosen as food by herbivores. It is also suspected to be allelopathic, releasing a toxin from its roots that stunts the growth of nearby plants of other species.

Common Name: Spreading Dogbane
Scientific Name: Apocynum androsaemifolium
Comments: Spreading dogbane is a showy member of the dogbane family (Apocynaceae) that is found in nearly all of the 50 states except some in the southeast. The common name, dogbane, and the genus name, “Apocynum,” meaning “away from dog,” are testaments to the toxic nature of this plant, not only to dogs, but to humans, livestock, and other mammals as well. The plant is poisonous due to the cardiac glycosides it contains.
Spreading dogbane is common in North America, and is widespread across most of the United States and Canada, and in Alaska, California, and northeast Mexico.

Common Name: Staghorn Sumac
Scientific Name: Rhus typhina
Comments: Staghorn sumac grows in gardens, lawns, the edges of forests, and wasteland. It can grow under a wide array of conditions, but is most often found in dry and poor soil on which other plants cannot survive. Some landscapers remove all but the top branches to create a “crown” effect in order to resemble a small palm tree.

Common Name: Summer Grape
Scientific Name: Vitis aestivalis
Comments: Vitis aestivalis, the summer grape, or pigeon grape, is a species of grape native to eastern North America from southern Ontario east to Maine, west to Oklahoma, and south to Florida and Texas. It is a vigorous vine, growing to 10 m or more high in trees.
Unlike most other species in genus Vitis, V. aestivalis does not propagate well through dormant cuttings. This has been a limiting factor for its use in commercial viticulture despite the species’ promising oenological characteristics.

Common Name: Sweetfern
Scientific Name: Comptonia peregrina
Comments: Sweetfern leaves are very aromatic. Edible fruit ripens in July and August. Sweetfern partners with actinomycete fungus that live in its root nodules to fix atmospheric nitrogen, so it can flourish in infertile soil. The soil in the area near Gavins Pond is relatively infertile because fill for the nearby Highway I-95 was taken from this area. It appears on some maps as “Sand Pits.”
The common name, sweetfern, is confusing, as it is not a fern. It is a deciduous shrub, growing to a maximum of five feet tall.
