Dicots |  Printer Friendly Version (PDF) |
Family: Bladderwort Family (Lentibulariaceae)
State Protection: Threatened Species 
This level of state protection means: 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 ½ 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? Butterwort is New York's only insectivorous plant which is not found in a marsh, bog, or swamp. Sometimes its pollinators are also unlucky enough to be caught and absorbed by the leaves. The name butterwort comes from its old world reputation of having medicinal and culinary uses. The juices from the leaves were rubbed onto cows' udders to protect them from infection. Another reference to butter was the use of its leaves to curdle milk. The genus name Pinguicula can be translated as little fat one or fattish for the greasy texture of the leaves. |

| State Ranking Justification |
| There are six known populations and approximately six additional historical populations of this plant. Most of these populations are on well-protected cliffs, but some cliffs may be subject to natural or artificial sloughing. This plant has a limited range, and an even greater limited habitat. As a plant at the southern limit of its range, it has always likely been rare in New York. |
