Taxonomic Comments
Kartesz (1999) accepted Lagophylla ramosissima ssp. congesta as distinct, however, the treatment in FNA (vol. 21, 2006) says that W.C. Thompson concluded in 1983 that this was a variant, unworthy of taxonomic recognition. Baldwin et al. (2012) agrees.

Ecology & Habitat

Description

Slender Hareleaf is an annual with simple or branched stems that are 1-6 dm high. The alternate, narrowly lance-shaped, entire-margined leaves lack petioles and are 1-8 cm long, becoming smaller upward. The foliage is densely covered with short, white hair, especially above. Short-stalked flower heads are borne in small, loose clusters at the tips of branches that arise from the axils of the upper leaves. Each head has a single series of 5 narrowly lance-shaped involucral bracts that are covered with long hairs and stalked glands, each enclosing a 3-lobed, pale yellow ray that is 2-6 mm long. Each of the 6 yellow disk flowers is enveloped by a scale. The achenes are shiny black and naked on top.

Diagnostic Characteristics

Species of MADIA are smaller and lack the long hairs on the involucre. Other annual members of the Asteraceae have more disk flowers or lack lobed rays. A hand lens and technical manual are required for positive determination.

Habitat

This species grows in grasslands or in the openings within chaparral, scrub, woodlands, and forests at elevations of 10 to 1,800 m asl (FNA 2006).
