Dicots |  Printer Friendly Version (PDF) |
Family: Evening-Primrose Family (Onagraceae)
State Protection: Endangered Species 
This level of state protection means: 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 ½ 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: G5T5
A Global Rarity Rank of G5T5 means: Secure globally - Both the species as a whole and the subspecies/variety are common in the world; widespread and abundant (but may be rare in some parts of its range). Did you know? The genus Epilobium was named by the Swedish botanist Linnaeus, the creator of our modern system of taxonomy. "Epilobium" is derived from Greek, and may be translated as "upon a capsule", a reference to how each flower sits atop an elongated ovary. The ovary then ripens into a long cigar-shaped fruit (the capsule). Epilobium species have long been used for medicinal purposes, and are the subject of current research into their anti-inflammatory and anti-bacterial properties. |

| There are currently only 5 confirmed locations for this species in New York. Only one of these has ever been observed to have a population of more than 50 individuals, and no population count has ever been made at 2 of the other sites. There are 2 historical occurrences, from Essex and Jefferson counties. |
