EASTERN CANADA AND NEW ENGLAND,— V. 
C. S.: SARGENT. 
§ TOMENTOSAE 
Anthers pink or rose color. 
* Stamens 10 or less. 
Crataegus fertilis, n. sp. Leaves oval to obovate, acuminate, 
gradually narrowed from near the middle and concave-cuneate at 
the entire base, sharply doubly serrate above, with straight teeth 
tipped with minute glands, and slightly divided above the middle into 
numerous narrow acuminate lobes ; nearly fully grown when the flow- 
ers open and then membranaceous, sparingly villose, dark yellow- 
green above, pale below; at maturity thin but firm in texture, glab- 
rous, dark green and lustrous on the upper surface, pale yellow-green 
on the lower surface, 7-9 cm. long, 5—6 cm. wide, with slender yellow 
midribs and 5-7 pairs of primary veins deeply impressed above ; 
petioles slender, grooved, more or less broadly wing-margined often 
nearly to the middle by the decurrent base of the leaf blades, 1.5-2.5 
cm. in length ; stipules linear, acuminate, minute, caducous. Flowers 
about 1.6 cm. in diameter on long slender pedicels, in broad thin- 
branched many-flowered compound villose corymbs; bracts and 
bractlets linear, glandular, small, mostly deciduous before the flow- 
ers open; calyx-tube broadly obconic, villose at the base, glabrous 
above, the lobes broad, acuminate, coarsely glandular-serrate, villose 
on the inner surface, reflexed after anthesis; stamens 8—r3, usually 
10; anthers rose color; styles 2 or 3. Fruit on stout slightly villose 
pedicels, in wide many-fruited slightly drooping clusters, subglobose, 
short-oblong or rarely ovate, dark red, very lustrous, marked by few 
small pale dots, about 1 cm. long; calyx prominent with a broad deep 
cavity and enlarged coarsely serrate lobes villose on the upper side, 
erect and incurved, mostly persistent; flesh yellow, thick and succu- 
lent; nutlets 2 or 3, about 7 mm. in length, thick, full and rounded at 
the ends, ridged on the back, with a broad deeply grooved ridge, the 
ventral cavities broad and deep. 
A shrub with numerous stems 3 or 4 m. in height and slender 
slightly zigzag branchlets marked by few large pale lenticels, orange- 
green when they first appear, soon becoming chestnut-brown and 
lustrous, darker during their second year and ultimately ashy gray, 
and armed with stout nearly straight bright red-brown spines 3.5-8.5 
cm. in length. Flowers early in June. Fruit ripens about the 2oth 
of September.
