Crataegus ouachitensis var. minor

E. J. Palmer

J. Arnold Arbor. 7: 124. 1926.

Conservation concernEndemic
Treatment appears in FNA Volume 9. Treatment on page 592. Mentioned on page 591.

Leaves: petioles ca. equal to length of blade; blade 2–3.5 cm, longer than wide to as long as wide, lobes somewhat more deeply incised, margins sharply serrate (more so than var. ouachitensis), abaxial surface more densely hairy on veins, adaxial more densely scabrous young. Inflorescences: branches sparsely villous. Pedicels ± tomentose young. Flowers: sepal margins subentire.


Phenology: Flowering Apr; fruiting Sep–Oct.
Habitat: Thickets along streams
Elevation: 100–300 m

Discussion

Of conservation concern.

Variety minor is very different from the typical variety. The entire plant is more or less glabrescent by maturity. It is quite possible that var. minor is a hybrid of C. marshallii, as originally suggested on the type material, in which case it is not a form of C. ouachitensis.
