Drosera rotundifolia L.
Droseraceae (Sundew Family)
USDA Symbol: DRRO
Insectivorous; white or pinkish flowers bloom near the bent end of a slender stalk that grows from a small basal rosette of reddish, sticky leaves.
The genus name, Greek for "dewy," refers to the moist, glistening drops on the leaves, to which small organisms stick. Longer-stalked glands near the edge of a leaf slowly bend inward, securing and placing an entrapped organism in the digestive area of stalkless glands. Sundews are able to survive on nutrient-poor soils where other plants are at a disadvantage. A similar species, the Spatulate-leaved Sundew (D. leucantha, currently considered synonymous with D. brevifolia), has oval or spoon-shaped leaves. The very similar, northern Narrowleaf Sundew (D. anglica) has much narrower, erect leaves and only grows as far south as northern Maine, Michigan, and Wisconsin. The Dwarf Sundew (D. brevifolia), which has wedge-shaped leaves with shorter stalks in a more compact rosette, is a more southerly species, occurring in damp areas from southern North Carolina to Florida, and west to Tennessee, Arkansas, and Texas.
