STAMENS usually 10; anthers dark purple. Leaves oval, acute, thin, bright 
yellow-green, drooping, and often convex. 
Cratzegus Pringlei, Sargent, Rhodora, iii. 21 (1901). 
A tree, occasionally twenty-five feet in height, with a tall trunk ten or twelve inches in diameter 
covered with thin bark readily separating in large flakes broken into small loose dark red-brown 
scales, and stout branches which form a wide symmetrical head. The branchlets are of medium 
stoutness, slightly zigzag, marked by small pale lenticels, and armed with thick straight or somewhat 
curved chestnut-brown spines often an inch and a half in length; when they first appear they are 
dark green and villose, and soon becoming glabrous they are chestnut-brown and lustrous during their 
first summer, bright orange-brown during their second year, and ultimately ashy gray. The leaves are 
oval, acute at the apex, rounded or often abruptly narrowed and cuneate at the base, occasionally 
irregularly lobed above the middle, with short broad acute lobes, and coarsely and often doubly serrate, 
with glandular teeth ; as they unfold they are villose on both surfaces and often more or less tinged 
with red, and when the flowers open, usually during the last week of May, they are roughened above 
by short closely appressed pale hairs and glabrous below with the exception of a few hairs on the 
slender midribs and remote primary veins ; and at maturity they are thin, glabrous and bright yellow- 
green on the upper surface, pale on the lower surface, from two inches to two inches and a half 
long and from an inch and three quarters to two inches and a quarter wide; they are usually con- 
spicuously concave by the gradual turning down of the blades from the midribs to the margins, and 
droop on thin slender glandular petioles which, villose at first, are ultimately glabrous, and from an 
inch to an inch and three quarters in length. The stipules are slightly faleate, conspicuously glandular- 
serrate, and caducous. On vigorous leading shoots the leaves are sometimes truncate or slightly cordate 
at the base, and frequently three inches long and broad. The flowers, which are about three quarters 
of an inch in diameter, are produced in many-flowered compound thin-branched villose corymbs, with 
linear acute straight or faleate bracts and bractlets. The calyx-tube is narrowly obconic and villose, 
particularly toward the base, and the lobes are narrow, acuminate, coarsely glandular-serrate, and villose 
on both surfaces or only on the inner surface, and generally reflexed after the flowers open. There are 
usually ten but occasionally from five to ten stamens with slender elongated filaments and small purple 
anthers, and from three to five styles surrounded at the base by conspicuous tufts of pale tomentum. 
The fruit, which ripens and falls late in September or early in October, is borne on stout pedicels 
often three quarters of an inch in length, in erect villose mostly few-fruited clusters ; it is oblong, dark 
dull red marked by a few large dark dots, villose at the ends, with long scattered pale hairs, three 
quarters of an inch long and about five eighths of an inch thick; the calyx-cavity is deep and narrow, 
and the lobes are gradually narrowed from broad bases, acuminate, glandular-serrate, and often erect ; 
the flesh is thick, yellow, dry, and acid, with a disagreeable flavor. The nutlets, which vary from three 
to five in number, are rounded and slightly ridged on the back, and a third of an inch in length. 
Crategus Pringlei is distributed from southern New Hampshire through the Champlain valley, 
where it is common on both sides of Lake Champlain as far north at least as Burlington, Vermont, to 
Rochester, New York, and Toronto, Canada, and through the southern peninsula of Michigan to 
Barrington, Illinois.
