Mountain Tail Leaf

Pericome caudata A. Gray

Comments

provided by eFloras
Populations of Pericome caudata may vary in leaf shape, head size, and indument, particularly in some far western and eastern populations. Central populations (e.g., in Colorado, New Mexico, and Arizona) tend to have relatively large, deltate-hastate leaves with long-attenuate tips and capitulescences of medium-sized heads. Specimens from Nevada and California often have smaller, ovate or cordate distal leaves with short-attenuate tips, as well as larger and fewer heads per capitulescence. Oklahoma specimens are often coarsely pubescent with copious glands and have leaves similar to the Nevada and California populations. This variability does not appear to warrant taxonomic distinction, nor does the presence or absence of pappus bristles appear to be taxonomically significant.

Pericome caudata

provided by wikipedia EN

Pericome caudata is a species of flowering plant in the aster family known by the common name mountain tail-leaf. It is native to the southwestern United States as far east as Colorado, Oklahoma, and Texas, as well as northern Mexico, where it grows in rocky habitat, often in hills and mountains, and sometimes in disturbed areas. It is a large, branching, leafy perennial herb or subshrub approaching 2 meters in maximum height. It is glandular, resinous, sparsely hairy, and aromatic. The leaves are somewhat triangular, sometimes with a few large teeth or sharp lobes, the blade measuring up to 12 centimeters long and borne on a petiole. The leaf size and shape is variable across the species' range.[1] The inflorescence is a cluster of many flower heads each under a centimeter wide and filled with golden yellow disc florets. The Navajo used this plant for a variety of medicinal and ceremonial purposes.[2]
