Whitemargin Pussytoes

Antennaria marginata Greene

Comments

provided by eFloras
Antennaria marginata has rims of white hairs (from the abaxial faces) around its adaxially glabrous leaves. It has both dioecious and gynoecious populations and cytotypes ranging from diploid to decaploid (R. J. Bayer and G. L. Stebbins 1987). It is probably a primary sexual progenitor of the A. parvifolia polyploid complex; the two taxa sometimes overlap morphologically; they differ in induments of basal leaves. Antennaria marginata may also be a contributor to the parentage of the A. howellii and A. rosea agamic complexes.

Antennaria marginata

provided by wikipedia EN

Antennaria marginata is a North American species of flowering plant in the family Asteraceae known by the common name whitemargin pussytoes.[2] It is native to northern Mexico (Chihuahua, Coahuila) and the southwestern United States (Arizona, New Mexico, western Texas (Jeff Davis County), Colorado, Utah, southern Nevada (Clark County), and southern California (San Gregorio Mountain in San Bernardino County)).[2][3][4]

Antennaria marginata is a small plant rarely more than 20 cm (8 inches) tall. The scientific epithet "marginata" and the "whitemargin" part of the common name refer to the fact that the leaves are hairless over most of the blade but with a ring of white wool-like hairs along the edge. The plants are dioecious, meaning that male and female flowers are borne on separate plants; some populations are known with no male plants.[2][5]
