Discussion

Usually scarce, Crataegus alabamensis occurs in south-central Alabama and northern Florida near Tallahassee. The type location is recorded as being on clay soil near Montgomery, Alabama, a somewhat unusual habitat for this series.

Crataegus alabamensis, with its crenate-serrate leaves, resembles the larger forms of C. condigna (subser. Tenues); it is a more robust plant with much larger flowers and fruits. The type form has leaves particularly wide relative to length. The rare C. adunca has, unusually for this series, violet anthers.
