State Protection: Endangered
listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
The genus name comes from the Greek "ips homoios" meaning "resembling a worm". This refers to its vining habit (Wikipedia contributors). The species name comes from the resemblance of its leaves to the pandura, an ancient musical instrument originally from Persia and Assyria (Wikipedia contributors) and refers to the leaf shape of some of the leaves when they widen again toward the apex. The roots of this plant can grow very large and were used by Native Americans for food and medicine. At first bite the taste of sweet potato is followed by a bitter aftertaste (Wikipedia contributors).

State Ranking Justification [-]
There are only two existing populations, and both of them are very small with fewer than 50 plants each. Both of them grow along the roadside and are not protected. There are 10 records from the late 1800s through 1968, but five of these are considered gone because their habitat, mostly from the New York City area, has been destroyed. Five of these populations have not been rechecked.
