Ecology & Habitat

Description

Obscure Evening-primrose is a small annual herb with stems, 3-15 cm high, that branch from the base and make the plant broader than it is tall. The strap-shaped leaves, 5-25 mm long, are clustered at the base of the plant and at the upper portions of the stems. Foliage is finely hairy. Tiny flowers are attached to the stem at the base of upper leaves. The 4 separate, yellow petals are 1-2 mm long, and the 4 sepals are reflexed. The stigma is ball-shaped. Petals and sepals are attached at the top of the ovary, which matures into a narrowly club-shaped capsule, 4-8 mm long, with the widest point attached to the stem.

Diagnostic Characteristics

C. ANDINA can be distinguished from other annual members of the genus by the small, yellow petals, ca. 2 mm long, and by its sessile capsules. A hand lens may be necessary for positive determination.
