Ecology & Habitat

Description

Common Clarkia is an annual with mostly unbranched stems that are 15-50 cm tall. The few leaves are opposite and have 1-3 cm long petioles and lance-shaped to elliptic, entire-margined, 2-7 cm long blades. The herbage is sparsely covered with short hairs. The few flowers are borne in a loose, narrow, nodding inflorescence which terminates the stem; the 4 separate petals are spoon-shaped, 5-10 mm long, and rose-purple, often with purple dots. The ovary is club-shaped and below the point of attachment of the petals. The fruits are capsules which are 1.5-3 cm long; each has a short beak at its tip.

Diagnostic Characteristics

The species is most easily confused with EPILOBIUM, but can be distinguished by having seeds without a tuft of hairs at the tip.
