Cratzgus Peoriensis, Sargent, Bot. Gazette, xxxi. 5 (1901). 
A nearly glabrous tree, usually from twenty to twenty-five feet in height, with a trunk occasionally 
a foot in diameter covered with dark brown scaly bark, and stout spreading branches forming a broad 
flat-topped symmetrical head. The branchlets are slender, somewhat zigzag, marked by numerous small 
pale lenticels, and armed with straight or slightly curved thin dull chestnut-brown spines from two inches 
to two inches and a half in length; green more or less tinged with red when they first appear, they 
become light orange-brown and lustrous during their first season, lighter colored during their second 
year, and ultimately ashy gray. The leaves are obovate, short-pointed or occasionally rounded at the 
broad apex, gradually narrowed, cuneate, and entire below, sharply and often doubly serrate, usually 
only above the middle, with straight or incurved glandular teeth, and sometimes irregularly lobed, with 
short broad terminal lobes; when they unfold they are villose on the upper surface, particularly 
toward the base of the midribs, and are bright bronze color, and when the flowers open during the 
latter part of May they are nearly fully grown and still slightly villose; in the autumn they are thick 
and firm, glabrous, dark green and very lustrous on the upper surface and pale on the lower surface, 
an inch and a half to two inches long and three quarters of an inch wide, with four or five pairs of thin 
primary veins raised and conspicuous on the under side, deeply impressed on the upper side, and 
extending very obliquely from the slender midribs to the ends of the lobes; they are borne on broad 
deeply grooved petioles usually about a quarter of an inch in length, more or less wing-margined and 
slightly glandular above the middle, and covered early in the season with short pale deciduous hairs. 
The stipules are linear-lanceolate, glandular-serrate, and caducous. On vigorous leading shoots the 
leaves are sometimes deeply divided into broad acute lateral lobes, and are from two to three inches 
long and an inch and a half wide, and their stipules are foliaceous, lunate, coarsely glandular-serrate, 
and sometimes an inch in length. The flowers are cup-shaped and about half an inch in diameter, 
and are borne on slender elongated pedicels, in broad loose compound many-flowered thin-branched 
glabrous corymbs, with linear conspicuously glandular caducous bracts and bractlets. The calyx-tube is 
narrowly obconic, and the lobes are narrow, acuminate, entire or irregularly glandular-serrate, with 
minute scattered dark red glands, pubescent below the middle on the upper surface, and spreading or 
reflexed when the flowers open. There are ten stamens with slender elongated filaments and small 
rose-colored anthers, and two or three styles surrounded at the base by a narrow ring of pale tomentum. 
The fruit ripens early in October, and hangs in droopmg many-fruited clusters, on slender elon- 
gated pedicels; it is oblong or obovate, full and rounded at the ends, slightly depressed at the 
insertion of the stalk, bright scarlet marked by many small dark dots, and from one half to three 
quarters of an inch in length; the calyx-cavity is broad and deep, and the enlarged lobes are usually 
erect and incurved and persistent; and the flesh is thick, nearly white, firm, and dry. The two or 
rarely three nutlets are thick, prominently ridged on the back, with broad rounded ridges, and about a 
quarter of an inch long. 
Crategus Peoriensis grows in open woods by the moist borders of streams and depressions in the
