New York Natural Heritage Program
Large Fruited Fireweed
Erechtites hieraciifolius var. megalocarpus (Fern.) Cronq.
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: G5T3
A Global Rarity Rank of G5T3 means: Vulnerable globally - The subspecies/variety is at moderate risk of extinction due to rarity or other factors; typically 80 or fewer populations or locations in the world, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. (The species as a whole is common globally.)

Did you know?
The Latin genus name was traditionally treated as grammatically feminine but the International Code of Botanical Nomenclature (naming code) states that names ending in "-ites" are to be treated as masculine. (Weldy, Troy and David Werier 2010). Therefore the species name has been changed from hieraciifolia in previous lists to hieraciifolius.

State Ranking Justification [-]
There are four existing populations but many thousands of plants on Fishers Island in the Long Island Sound. More populations are expected to be found on the North Fork and elsewhere on Eastern Long Island with more intensive surveys. There is only one, possibly two, historical records from the early 1900s.
