176 Rhodora [OCTOBER 
petioles slender, slightly wing-margined at the apex, grooved on the 
upper side, glabrous, often dark rose color late in the season, 3-4 cm. 
in length. Flowers about 1.5 cm. in diameter, on slender elongated 
glabrous pedicels, in wide lax usually 8—10-flowered corymbs, with 
linear glandular bracts and bractlets fading rose color and mostly 
deciduous before the flowers open; calyx-tube narrowly obconic, 
glabrous, the lobes slender, entire or occasionally glandular-dentate 
near the middle, tinged with red toward the acuminate apex, glabrous 
on the outer and puberulous on the inner surface, reflexed after 
anthesis; stamens 10; anthers pale pink; styles 2 or 3. Fruit 
ripening the end of September, on slender red pedicels, in few-fruited 
drooping clusters, oval, bright scarlet, covered with a slight bloom, 
marked by small pale dots, 1.2-1.4 cm. long; calyx little enlarged, 
with a narrow deep cavity, and closely appressed lobes pubescent on 
the upper side, their tips often deciduous from the ripe fruit; flesh 
thin, greenish yellow; nutlets 2 or 3, full and rounded at the ends, 
or when 3 narrowed and acute at the apex, ridged on the back, with 
a broad low deeply grooved ridge, penetrated on the inner faces by 
broad shallow irregular cavities, about 6 mm. long and 4 mm. wide. 
A broad shrub, with stout nearly straight branchlets marked by 
small oblong pale lenticels, dark orange-green and glabrous when 
they first appear, becoming bright chestnut-brown and lustrous dur- 
ing their first season, orange-brown and lustrous in their second year, 
and ultimately light gray tinged with red, and armed with numerous 
stout straight or slightly curved chestnut-brown shining spines 3-5 
cm. long.

The relationship of this species is with Crataegus fertilis, Sarg., of 
the Penobscot Valley, Maine (see RHODORA, v. 182), but it differs 
from that species in its scabrate leaves, smaller at the flowering time, 
more slender petioles, glabrous pedicels and corymbs, narrow nearly 
entire and less hairy calyx-lobes, in its less lustrous fruit in fewer- 
fruited clusters, and in its shorter and more slender spines. 
Crataegus baccata, n. sp. Leaves rhombic to oval or rarely 
obovate, short-pointed and acuminate at the apex, gradually nar- 
rowed and concave-cuneate at the entire base, finely often doubly 
serrate above, with straight glandular teeth, and slightly divided 
above the middle into 4 or 5 pairs of small acuminate lobes, more 
than half grown when the flowers open during the first week of May 
and then membranaceous, light yellow-green, roughened by short 
white hairs and pubescent or villose along the midribs above and 
pale and glabrous with the exception of a few axillary hairs below, 
and at maturity thin but firm in texture, smooth, lustrous, and yellow-
