S ummary The seed production of hand pollinated flowers indicates that distylous Cryptantha flava (A. Nels.) Payson is both intramorph and self‐compatible. In addition, there is no inhibition of pollen tube growth following either intramorph or self‐pollinations. Despite the potential for crosses between individuals of the same style length and thus the production of unequal morph ratios, pins and thrums occur in equal numbers in natural populations.
