1899 ] STUDIES IN CRATA:GUS 417 
20, 3-5" long: styles 3-5, surrounded at the base with pale 
hairs: fruit globose, 8—-9"" in diameter, dull, dark-red or green- 
ish-red, or frequently covered with black spots and blotches, 
tripe about the first of October and hanging until early winter, 
the cavity 2-3"" wide and deep, bordered by the remnants of 
the calyx lobes and stamens: nutlets 3-5, thick-walled, 5—7"" 
long, about 3°" wide measured dorso-ventrally, with a promi- 
nent ridge and two deep grooves on the back, the inner faces 
nearly plane. 
Crategus Mohri is distributed from Georgia westward through 
upper and central Alabama and Mississippi, and northward to 
middle Tennessee. It reaches its best development in the rich 
and moist soil of the ‘“flat-woods” of central Alabama, though 
not infrequently it ascends into the poorer and drier soil of the 
hills and mountains. The species has been usually confounded 
with Crategus crus-galli L.,3 or more recently with C. collina 
Chapm.6 From the former it may be recognized by the pilose 
corymbs, smaller and globular fruit, more numerous and smaller 
nutlets, habit of growth, and by the outline of the leaves; while 
from C. collina it may be separated by the later time of flower- 
ing, smaller fruit and nutlets, and by the luster of the leaves. 
I take pleasure in associating with this beautiful and most 
distinct hawthorn, the name of Dr. Charles Mohr, of Mobile, 
Alabama. 
The type material is preserved in the Biltmore Herbarium.
