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 the 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: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery. Did you know? These plants are difficult to find when they are not in flower, because their tall thin stems and narrow leaves blend in well with other wildflowers and grasses. The species name is Latin for grooved and refers to the grooved stems of these plants. It was given that name by John Riddle, a 19th century botanist who received his early training in botany from Amos Eaton at Rensselaer Polytechnic Institute in Troy, New York (Dexter 1988). |

| State Ranking Justification | [-] |
There are eight existing populations, but only four of them have populations that contain hundreds of plants. Some smaller populations are threatened by succession, and one population from the 1980s that contained 200 to 300 plants may have been lost to succession. There are 14 historical occurrences, but the likelihood of relocating them is low because many of them were from the fields or roadsides of the first half of the 20th century, that have long since succeeded to forest or have been developed.
| Short-term Trends | [-] |
The short-term trend seems stable with some variability in numbers from year-to-year, but no existing populations have become extirpated.
| Long-term Trends | [-] |
This species was never common in New York, but there has been a decline from historical numbers, as open areas have become more forested and land has been developed.
