Paronychia argyrocoma
Plants of Paronychia argyrocoma with glabrous or barely scabrous leaves and glabrous sepal awns have sometimes been recognized as var. albimontana. They are found in both the southern and northern areas of the species range, but, curiously, not in the central portion (M. N. Chaudhri 1968).
