Discussion
Variety reverchonii is common in parts of the Edwards Plateau, Texas, and extends to southwestern Missouri and northwestern Louisiana. It is the most abundant variety and, with its small flowers, 3–5 styles and pyrenes, the most distinctive; in other respects, it is far from uniform. The type form, with 10 stamens and pink anthers, is recorded from Texas; Crataegus stevensiana, with 10 stamens and cream anthers, occurs through most of the range. Less common variants, which may have slightly larger leaves and flowers and all occur in Missouri are: C. jasperensis Sargent (20 stamens and yellow anthers), C. parciflora Sargent and C. rotunda Sargent (both with 20 stamens and rose anthers), and C. discolor (10 stamens and rose anthers). These are in some respects intermediate with var. palmeri.
