A tree, from twenty to twenty-five feet in height, with a short trunk a foot in diameter, and stout 
ascending branches forming a broad irregular head; or often shrubby and beginning to flower when 
only a few feet tall. The bark of the trunk is thin and separates freely into large pale reddish brown 
or gray-brown scales which in falling disclose the bright red-brown inner bark. The branchlets are 
stout, zigzag, and armed with thick or thin nearly straight dark red-brown ultimately gray spines from 
an inch and a half to two inches in length; when they first appear they are coated with thick hoary 
tomentum, and during their first summer they are dark red-brown and pubescent, becoming darker 
colored and glabrous the following season. The leaves are usually three-nerved, broadly ovate or 
orbicular, acute or rounded at the apex, generally narrowed and cuneate or concave-cuneate at the 
glandular entire base, serrate or doubly serrate above, with straight or incurved glandular teeth, and 
mostly divided above the middle into several short acute lobes; when they unfold they are coated with 
long matted snow-white hairs which are more abundant on the lower than on the upper surface, and 
when the flowers open about the middle of April they are more than half grown, blue-green and villose 
above and still tomentose below; in the autumn they are thin but firm in texture, blue-green and 
glabrous on the upper surface, pale and slightly pubescent on the lower surface, particularly along the 
slender nerves, and usually about an inch long and from three quarters of an inch to an inch wide; 
they are borne on slender tomentose ultimately pubescent or villose broadly grooved glandular petioles 
slightly widened above by the decurrent bases of the leaf-blades, and usually about a third of an inch in 
length. The stipules are lunate, coarsely glandular-serrate, from one sixteenth to one eighth of an inch 
long, and caducous. On vigorous leading shoots the leaves are broadly ovate or suborbicular, full and 
rounded at the broad base, coarsely serrate, often deeply divided above the middle into three wide acute 
lobes, and frequently broader than they are long. The flowers are about five eighths of an inch in diam- 
eter, and are produced on slender tomentose pedicels, in simple three to seven-flowered corymbs, with 
narrow obovate acute glandular bracts and bractlets. The calyx-tube is narrowly obconic, coated with 
pale tomentum, and the lobes are narrow, acute, glandular-serrate, with minute bright red glands, tomen- 
tose on the outer surface, glabrous on the inner surface, and reflexed after the petals fall. There are 
twenty stamens with small light yellow anthers, and from three to five styles surrounded at the base by a 
ring of pale tomentum. The fruit ripens late in August or early in September, and is borne on slender 
pubescent pedicels, in few-fruited clusters; it is subglobose or oblong, light red, puberulous toward the 
ends, and about a third of an inch in diameter, with a prominent calyx, and thin subacid yellow flesh. 
The nutlets vary from three to five in number, and are thick, rounded, and obscurely ridged on the back, 
dark brown, and a quarter of an inch long.’ 
Crategus dispar grows on the dry sand hills near Aiken and Trenton, South Carolina, and near 
Augusta, Georgia, where it is very abundant in Summerville its western suburb.
