Crategus pyriformis, Britton, Bull. N. Y. Bot. Gard. i. 449 (1900) ; Man. 522. 
A tree, twenty-five or thirty feet in height, with a trunk a foot in diameter covered with thick dark 
scaly bark, and spreading branches forming a broad symmetrical head. The branchlets are slender, 
somewhat zigzag, marked by small oblong pale lenticels, and armed with occasional thin nearly straight 
bright chestnut-brown lustrous spines usually about an inch and a half in length; light green and 
villose when they first appear, with long matted pale hairs, they are dull red-brown and pubescent in 
their first summer, light brown and glabrous the following year, and ultimately ashy gray. The leaves 
are oval or broadly ovate, acute and often short-pointed at the apex, gradually narrowed and concave- 
cuneate at the entire base, sharply and sometimes doubly serrate above, with straight glandular teeth, 
and often slightly and irregularly lobed above the middle; when the flowers open about the tenth of 
May they are fully grown and membranaceous, light yellow-green, roughened on the upper surface by 
short rigid pale hairs and pubescent on the lower surface, particularly along the slender midribs and five 
or six pairs of remote primary veins; and at maturity they are thin and firm, lustrous and scabrous on 
the upper surface, pale and pubescent on the lower surface, and generally about three inches long and 
two inches wide ; they are borne on slender grooved tomentose ultimately pubescent petioles broadened at 
the apex by the decurrent bases of the leaf-blades, and from an inch to an inch and a quarter in length. 
The stipules are minute, linear-lanceolate, bright red, and caducous. On vigorous leading shoots the 
leaves are usually ovate, coarsely serrate, more deeply lobed than the leaves of fertile branchlets, and 
frequently four or five inches long and three or four inches wide, with foliaceous lunate acuminate 
villose coarsely serrate stipules sometimes half an inch long. The flowers are an inch in diameter, and 
are produced on elongated slender tomentose pedicels, in broad compound many-flowered lax corymbs, 
with linear-lanceolate or oblanceolate glandular-serrate elongated caducous bracts and bractlets. The 
calyx-tube is narrowly obconic and villose, and the lobes are narrow, acuminate, glandular-serrate, and 
more or less villose. There are twenty stamens with pale rose-colored anthers, and four or usually five 
styles surrounded at the base by a broad ring of white tomentum. The fruit ripens in October, and 
hangs on long slender pubescent pedicels, in drooping few-fruited clusters; it is obovate, full and 
rounded at the ends, bright cherry-red, lustrous, marked by occasional large pale dots, and about five 
eighths of an inch long and one half of an inch wide; the calyx is prominent, with a broad shallow 
cavity, and linear glandular-serrate closely appressed lobes often deciduous before the fruit ripens ; the 
flesh is thin, light yellow, and juicy. The four or usually five nutlets are deeply divided along the back 
into two rounded ridges, dark brown, and five eighths of an inch in length. 
Crategus pyriformis grows on the rich bottom-lands of streams in Ripley County, southeastern 
Missouri, where it was discovered near Monteer in August, 1899, by Mr. B. F. Bush.
