Ecology & Habitat

Description

Miner's Candle is a slender annual herb with simple or branched stems that are 5-15 cm high. The alternate, narrow, strap-shaped leaves are 2-4 cm long; those at the base are usually brown by the time the plant is fruiting. Stems are sparsely covered with straight hairs appressed to the surface, while the leaves have some spreading hairs. Tiny, white flowers are borne on coiled stalks that unwind and elongate as flowering progresses from the base upward. The corolla is ca. 1 mm high and has a small united portion below and 5 spreading petals above. The narrow calyx is covered with bristly hairs and becomes 4-6 mm long in fruit. The 4 lance-shaped nutlets are ca. 2 mm long, ca 0.5 mm wide, and are finely bumpy.

Diagnostic Characteristics

Annual species of CRYPTANTHA are distinguished by characters of the seeds, so a hand lens or microscope is essential. C. SCOPARIA is distinguished by having 4 similar nutlets that are covered with fine bumps and that are ca. 4 times as long as they are wide.

Habitat

Dry open slopes in mixed desert shrub, sagebrush, and pinyon -juniper communities, 4750-6250 feet.
