Dicots |  Printer Friendly Version (PDF) |
Family: Aster Family (Asteraceae)
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: G2
A Global Rarity Rank of G2 means: This species is imperiled globally because of rarity (typically 6 - 20 known populations or few remaining individuals) or very vulnerable to extinction throughout its range because of other factors. Did you know? Boott's Rattlesnake-root is restricted to the northeastern United States where it only grows on a few mountain summits in New York and New England. The genus name comes from the Greek "prenes", drooping, and "anthe", flower, and it describes the habit of the flower (Fernald 1970). It is named after John Wright Boott (1788-1845) who first collected the plant in 1829 in the White Mountains of New Hampshire (Fernald 1970, Wallner and DiGregorio 1997). |

| State Ranking Justification | [-] |
There are six known populations in New York with only one that has over 500 individuals and two that have under 50. This species is globally limited in number of individuals and in extent of range being endemic only to the mountains of New England and New York.
| Short-term Trends | [-] |
In the past 20 years or so populations appear to have remained stable or to have fluctuated up and down slightly. These data may be somewhat inaccurate due to the difficulty of noticing and assessing all basal rosettes as well as the different levels of survey effort.
| Long-term Trends | [-] |
No populations are known to have become extirpated but there are no other clear data indicating what the long-term trends are for this species.
