Anisocarpus scabridus, the leafy raillardiopsis, is a North American species of flowering plants in the family Asteraceae.

Distribution It is found only in northwestern California, primarily in scree slopes at relatively high elevations in the Coast Ranges of Humboldt, Mendocino, Trinity, Lake, Tehama, and Colusa Counties. There are also a few isolated populations in the southern Cascades of northern Shasta County.Biota of North America Program 2014 county distribution mapCalflora taxon report, University of California, Anisocarpus scabridus (Eastw.)

Description Anisocarpus scabridus is a small plant rarely more than 2 inches (5 cm) high. It has blue-green leaves and flower heads containing both ray florets and disc florets.Flora of North America Vol. 21 Page 301 Anisocarpus scabridus (Eastwood) B. G. Baldwin

The plant is quite different in ecology and appearance from the only other species in the genus, A. madioides. The two were classified in different genera for many years until molecular and anatomical studies in the 1990s demonstrated their close relationship.Baldwin, Bruce G. 1999. Novon 9(4): 462-471.
