Morphology
The leaves of the common sundew are arranged in a basal rosette. The narrow, hairy, 1.3–5.0 cm long petioles support 4–10 mm long laminae. The upper surface of the lamina is densely covered with red glandular hairs that secrete a sticky mucilage.
A typical plant has a diameter of around 3–5 cm, with a 5–25 cm tall inflorescence. The flowers grow on one side of a single slender, hairless stalk that emanates from the centre of the leaf rosette. White or pink in colour, the five-petalled flowers produce 1.0–1.5 mm, light brown, slender, tapered seeds.
In the winter, D. rotundifolia produces a hibernaculum to survive the cold conditions. This consists of a bud of tightly curled leaves at ground level.

Famous quotes containing the word morphology:
“I ascribe a basic importance to the phenomenon of language.... To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization.”
—Frantz Fanon (1925–1961)
