Discussion
Subspecies macrocarpa has rarely been collected; it is common within its limited range on western slopes of the Sierra Nevada. Its cypselae are the largest of any of the annual stephanomerias. Unlike the other subspecies of Stephanomeria exigua, which are self-incompatible and obligately outcrossing, subsp. macrocarpa is self-compatible and highly self-pollinating. In Kern County, hybrid individuals may be found wherever subsp. macrocarpa and subsp. coronaria make contact.
