Discussion
Of conservation concern.
Crataegus austromontana is a possibly extinct species; it was last collected in 1916. Beadle reported that it occurred throughout the Sand Mountain region of Alabama and had also been collected in the Cumberland Mountains and hill country of eastern and middle Tennessee. The species is similar to C. triflora but has wider, usually larger and more deeply incised leaves, and only ten stamens.
