Comments

Although Arnica dealbata lacks pappi, morphologic, cytologic, and molecular data (B. G. Baldwin and B. L. Wessa 2000; Baldwin et al. 2002) clearly support its inclusion in Arnica.

Arnica dealbata is a species of Californian plants in the tarweed tribe within the aster family[3][4]

The species is known by the common name mock leopardbane.[5]

Distribution and habitat

It is endemic to California, where it is known from the Sierra Nevada and the southernmost slopes of the Cascade Range.[5][6] It occurs in forest and meadow habitat in the mountains and foothills.

This plant is uncommon throughout its limited distribution and is listed as a sensitive species of Yosemite National Park, where it occurs in two locations.[7]

Description

It is a hairy, glandular, rhizomatous perennial herb producing an erect stem up to about 35 centimeters tall. The leaves have lance-shaped or pointed oval blades up to 10 centimeters long which are borne on petioles. They are arranged in opposite pairs, mostly near the base of the stem. The blades are coated densely in short curly hairs, some glandular. The inflorescence is a solitary flower head or cluster of a few heads. The head contains up to 12 yellow ray florets up to 2.5 centimeters long with many yellow disc florets at the center.[8]
