S-2 State rare. Imperiled in Maryland because of rarity.
S-3 Watchlist. Rare to uncommon in Maryland, worthy of attention due to limited distributions, declining populations, or ecological vulnerabilities.
S-H Historically known from Maryland, but not verified for an extended period (usually 20 or more years), with an expectation that it may be rediscovered.

State Status

E Endangered: A species whose continued existence as a viable component of the state's flora or fauna is determined to be in jeopardy.
T Threatened: A species of flora or fauna which appears likely, within the foreseeable future, to become endangered in the state.
X Extirpated: A species that was once a viable component of the flora or fauna of the state, but for which no naturally occurring populations are known to exist in the state.
* Historic Occurrence - These plants are known to have historically occurred in the indicated watershed, however it is not known if they still exist there today.

Note: the area historically known as the "Powder Mill Bogs" occurred in BOTH watersheds. There were numerous bog sites in this area, nearly all of which have been destroyed.
