1905] Sargent, Recently Recognized Species of Crataegus 211 
side, glabrous, glandular toward the apex, with minute deciduous 
glands, often rose color in the autumn, 2—2.5 cm. in length; stipules 
linear, acuminate, glandular, fading brown, caducous; leaves on vig- 
orous shoots suborbicular to broad-obovate, coarsely serrate, only 
slightly lobed, subcoriaceous, often 6-7 cm. long and wide, with stout 
glandular petioles. Flowers 1.6—1.8 cm. in diameter, on slender gla- 
brous pedicels, in compact usually 12-15-flowered corymbs, with 
linear glandular rose-colored bracts and bractlets; calyx-tube nar- 
rowly obconic, acuminate and red at the apex, glandular with minute 
dark red stipitate glands, reflexed after anthesis; stamens 7-10; an- 
thers rose color; styles 3 or 4. Fruit ripening the end of September 
and persistent until winter, on slender reddish pedicels, in drooping 
few-fruited clusters, subglobose to short-oblong, orange-red, marked 
by small pale dots, 1.2-1.4 cm. long and about 1 cm. wide; calyx 
only slightly enlarged, with a wide deep cavity and spreading red 
lobes, their tips often deciduous from the ripe fruit; flesh thin, yel- 
low, dry and mealy; nutlets 3 or 4, full and rounded at the ends, 
ridged on the back, with a high rounded ridge, 7-8 mm. long and 
4-5 mm. wide. 
An arborescent shrub 4-5 m. high, with ascending stems 5-7 cm. 
in diameter near the ground, and stout nearly straight branchlets 
marked by small oblong pale lenticels, light orange-green and gla- 
brous when they first appear, light orange-brown and very lustrous 
during their first winter and dark gray-brown the following year, and 
armed with numerous stout nearly straight bright chestnut-brown and 
shining ultimately dull gray-brown spines 3-3.5 cm. long.

The relationship of this species is with C. Zgg/estoni, Sarg., from 
which it differs in its much thicker semiorbicular leaves, larger flow- 
ers, glabrous corymbs and calyx-lobes, larger fruits and darker-colored 
nutlets, with dorsal ridges without grooves or only slightly grooved, 
and in the color of the branchlets and the length and color of the 
spines. 
Crataegus Ideae, n. sp. Leaves, oval to ovate or obovate, short- 
pointed and acute at the apex, concave-cuneate and entire at the base, 
finely and occasionally doubly serrate above, with incurved conspicu- 
ously glandular teeth, and slightly divided above the middle into broad 
acute lobes, faintly tinged with red when they unfold, more than half 
grown when the flowers open at the end of May and then thin, light 
yellow-green and covered above by short white hairs and pale and 
glabrous below with the exception of a few axillary hairs, and at
