Canby's dropwort [Oxipolis canbyi]

Canby's dropwort, which has a dill fragrance, is a perennial with stems up to 3.9 feet tall and bear quill-like leaves. Its white flowers are displayed in flat-topped clusters from May through early August. the plant spreads by rhizomes and prefers moist habitats such as swamps, pineland ponds and wet pine savannahs.

Historically, this species was widely spread along the coastal plain of stretching from Delaware to Georgia. When listed, ten sites were known: one each in Burke, Lee and Sumter counties, Georgia; one in Scotland County, N. Carolina; five in the counties of Bamberg, Barnwell, Colleton and Richland, S.Carolina; and one in Queen Anne's County, Maryland.

Major factor affecting Canby's Dropwort survival is draining and ditching of wetlands for agriculture, pine plantations, pasture and road building. The lowering of the water table has allowed other plants to become established, crowding out the dropwort.

Efforts for recovery of this species are focusing on reintroduction of individuals into suitable habitats within its former range.
