CRATAIGUS ANOMALA. 
Haw. 
STAMENS 10; anthers bright red. Leaves ovate, acutely lobed, membranaceous, 
yellow-green. 
Crataegus anomala, Sargent, Rhodora, iii. 74 (1901). 
A bushy tree, sometimes twenty feet in height, with a short trunk six inches in diameter covered 
with pale gray-brown scaly bark, and stout ascending branches. The branchlets, which are slender 
and somewhat zigzag, are marked by pale lenticels and armed with numerous stout straight or slightly 
curved bright chestnut-brown spines from an inch and a quarter to two inches in length; when they 
first appear they are dark green and villose, with long matted white hairs, and during their first season 
they are puberulous and light orange-brown, becoming in their second year orange-brown or bright red. 
The leaves are ovate, acute, divided above the middle into five or six pairs of short acute or acuminate 
lobes, and coarsely doubly serrate, with spreading glandular teeth except toward the broadly cuneate or 
occasionally rounded base; as they unfold they are conspicuously plicate, scabrous above, with short 
appressed pale hairs, and villose below, particularly along the slender midribs and thin remote primary 
veins which arch to the points of the lobes and are only slightly impressed on the upper side; at 
maturity they are membranaceous, yellow-green, smooth and glabrous on the upper surface, paler 
and villose on the lower surface, from two and a half to three inches long and from two to three 
inches wide; they are borne on stout slightly grooved petioles glandular on the upper side, with 
scattered dark glands, and from three quarters of an inch to an inch in length. The stipules are 
linear-lanceolate or, on leading vigorous shoots, falcate and very oblique at the base, and often half 
an inch long. The flowers, which are half an inch in diameter and become distinctly saucer-shaped 
when fully expanded, open at the end of May, and are borne on elongated slender pedicels, in broad 
loose many-flowered thin-branched villose corymbs, with lanceolate or oblanceolate finely glandular- 
serrate bracts and bractlets. The calyx-tube is narrowly obconic and covered with a thick coat of long 
matted pale hairs, and the lobes are elongated, acuminate, coarsely glandular-serrate, pubescent on the 
lower surface, and tomentose on the upper surface. There are usually ten but occasionally seven or 
eight stamens with large bright red anthers, and four or five styles which are surrounded at the base 
by a narrow ring of pale tomentum. The fruit ripens in October and hangs on slender stems from 
one half to three quarters of an inch in length, in loose many-fruited slightly villose clusters ; it is 
obovate to oblong, gradually narrowed to the rounded base, crimson, lustrous, marked by large pale 
scattered dots, and slightly villose, particularly toward the full and rounded apex, from three quarters 
to seven eighths of an inch long and from one half to five eighths of an inch wide; the calyx 1s large 
and prominent, with a broad shallow cavity, and elongated acuminate lobes which are abruptly narrowed 
from broad bases, dark red on the upper side, tomentose, finely glandular-serrate, spreading or closely 
appressed, and often deciduous before the ripening of the fruit; the flesh is thin, light yellow, and 
somewhat juicy. The four or five nutlets are thin, prominently and irregularly ridged on the back, and 
from one quarter to five sixteenths of an inch in length. 
Crategus anomala, of which only a few individuals are now known, inhabits the low hmestone 
ridges near the banks of the St. Lawrence River in the Caughnawaga Indian Reservation opposite 
Lachine in the Province of Quebec. It was discovered in May, 1900, by Mr. J. G. Jack.
