1903] Sargent, — Recently recognized Species of Crataegus 115 
This species, which is common in the valley of the St. Lawrence 
River in the neighborhood of Montreal, has been found at Walpole, 
New Hampshire, by W. W. Eggleston, October 1902, and at Crown 
Point, New York, by W. W. Eggleston, June and September, 1902, 
and by C. ZA. Peck, September 1902. A specimen with immature 
fruit collected by Ezra Brainerd at Ferrisburg, Vermont, July 1901, 
should perhaps be referred to this species. 
Crataegus contigua n. sp. Leaves ovate, acuminate, full 
and rounded or broadly cuneate at the glandular base, coarsely and 
often doubly serrate, with straight gland-tipped teeth and deeply 
divided into five or six pairs of acuminate spreading lobes; about 
one third grown when the flowers open and then membranaceous, 
covered above with short white hairs and glabrous below; at 
maturity thin but firm in texture, dark green, lustrous and scabrate on 
the upper surface, pale yellow-green on the lower surface 6-8 cm. 
long, 4.5—7 cm. wide, with slender yellow midribs and thin primary 
veins extending to the points of the lobes ; on vigorous shoots often 
broader than long, 7 cm. long, 7.5-8 cm. wide; petioles slender, 
nearly terete, frequently slightly wing-margined at the apex, glandu- 
lar with scattered minute dark glands 3-5 cm. in length. Flowers r.3— 
1.5 cm. in diameter on elongated slender pedicels, in many-flowered 
thin-branched glabrous compound corymbs; calyx-tube broadly 
obconic, the lobes abruptly narrowed from broad bases, linear, acu- 
minate, entire or rarely furnished with a few small scattered glandu- 
lar teeth, reflexed after anthesis; stamens 20; anthers small, pink; 
styles 3-5. Fruit in few-fruited drooping clusters, obovate at first 
when fully grown, becoming oblong and full and rounded at the ends 
at maturity, scarlet marked by occasional small pale dots; calyx 
cavity broad and shallow, the lobes spreading and appressed, often 
wanting from the ripe fruit; flesh thin, yellow; nutlets 3—%, usually 
4, thin, acute at the ends, conspicuously ridged on the back, with a 
broad grooved ridge, about 8 mm. long. 
A shrub 2-3 m. in height with numerous erect stems spreading 
into small thickets and stout nearly straight branchlets marked by 
few large pale lenticels, yellow-green when they first appear, light 
red-brown and lustrous during the first season and dull gray-brown 
the following year, and armed with stout nearly straight bright red- 
brown shining, ultimately ashy gray spines, 2.5—4.5 cm. long. 
Flowers during the first week of June. Fruit ripens about the 2oth 
of September and soon falls. 
VERMONT: banks of White River, Stockbridge, W. W. Eggleston, 
June, July and September 1901. Common.
