Discussion

Three races of Aphanes occidentalis are recognizable, apparently corresponding to previously described species. Some apparently intermediate plants exist, and not all specimens can be confidently assigned to these races, which are, therefore, not recognized as formal taxa here. The names under which they have been recognized and their distinguishing features and distributions are as follows:

Aphanes cuneifolia (Nuttall) Rydberg: hypanthium and calyx ovoid, 1 mm, smooth, often subglabrous; hypanthium contracted at apex, not densely hairy; epicalyx bractlets often present; sepals erect-connivent, 0.3–0.4 mm, 1/4–1/3 flower length. California; Mexico (Baja California).

Aphanes macrosepala Rydberg: hypanthium not contracted at apex, usually densely hairy, hairs spreading; epicalyx bractlets present; sepals spreading-erect, 0.5 mm, ca. 1/3 flower length. California, Oregon, Washington.

Aphanes occidentalis in the narrow sense: hypanthium and calyx ellipsoid, 1.5 mm, ± ribbed, sparsely short-hairy; hypanthium contracted at apex, not densely hairy; epicalyx bractlets usually absent; sepals usually connivent, 0.3–0.4 mm, 1/4–1/3 flower length. British Columbia; California, Oregon, Washington.
