Onosmodium virginianum plant Stephen M. Young
Family: Borage Family (Boraginaceae)

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: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
The genus name Onosmodium comes from this plant's similarity to the Eurasian genus Onosma, also in the Borage family.

State Ranking Justification [-]
There is one existing population of approximately 20 plants. There are 22 historical records mostly from the late 1800s and early 1900s from open disturbed areas on Long Island and the Lower Hudson region. The probability of relocating more populations is low because many of the areas have been developed or have been previously searched.
