rather inconspicuously, pubescent on both surfaces, the pubes- 
cence being more pronounced on the lower side and along the 
principal veins, which are disposed in about 5-7 pairs; acute 
at the apex, contracted at the rounded, truncate or sometimes 
subcordate base into a margined or winged petiole 1-4™ long, 
the borders very sharply and irregularly serrate, or frequently 
doubly serrate or incisely lobed, the serratures tipped with 
minute dark colored glands. 
Crategus austromontana is distributed throughout the Sand 
mountain region of Alabama, and has also been collected at 
several stations in the Cumberland mountains and hill country 
of eastern and middle Tennessee. The new species is closely 
associated with C. triflora Chapm., but may be recognized by its 
smaller size, broader leaves, fewer stamens, and by the larger 
and coarser seeds. The type material is preserved in the Bilt- 
more Herbarium. 
Crategus Harbisoni, n. sp.—A tree 5-8 meters in height, 
frequenting rocky slopes and ridges: leaves obovate, oval, or 
broadly ovate, 3-12 long including the petiole, 2-9 wide, 
acute at the apex, narrowed at the rounded or tapering base into 
margined or winged petioles; they are harshly and rather 
| Inconspicuously pubescent on the upper and more densely coated 
on the lower surface and along the 5-7 principal veins, sub- 
coriaceous, dark green and lustrous above, pale below, the 
borders doubly and irregularly serrate to near the base, or fre- 
quently incisely lobed: petioles 6™-2™ long, bearing, = does 
the extreme base of the blade, a number of stalked, black-tipped 
glands : stipules glandular-serrate or pectinately-glandular, 
deciduous, foliaceous on the stronger shoots, acute or lanate:

Tennessee (type locality), produced in broad, pubescent, or 
Pilose, divergently-branched corymbs, the lower branches from 
the axils of leaves: bracts subtending the branches of the 
orymbs large, 7-18™ long, 2-4™ broad, pectinately or
