Family: Flax Family (Linaceae)

State Protection: Threatened
listed species are those with: 1) 6 to fewer than 20 extant sites, or 2) 1,000 to fewer than 3,000 individuals, or 3) restricted to not less than 4 or more than 7 U.S.G.S. 7 minute topographical maps, or 4) listed as threatened by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S2
A State Rarity Rank of S2 means: This plant is threatened/imperiled in New York because of rarity (typically 6-20 populations or few remaining individuals) or is 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?
This beautiful little wildflower was first collected on Nantucket Island in 1899 by Eugene Bicknell and for many years was thought to be Linum floridanum. When he realized it was a distinct species he described it as Linum intercursum (Bicknell 1912). He did not give a reason for the species name (intercursum = running between) but we can surmise that it meant it was a species that had the characters between Linum floridanum and Linum medium. He called it one of the noteworthy plants of the Hempstead Plains on Long Island. It was first collected there in 1904 but remains elusive today and may now be gone from that site.

State Ranking Justification [-]
There are 10 existing populations which are highly threatened. Only 4 populations have more than 100 plants. There are 29 historical occurrences, but most of the habitat is gone.
