Antennaria marginata

Jump to: navigation, search


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.
