tion of thorns, however, planted by me in the garden perhaps about 
1875 and, like other trees and shrubs planted there at that time, it 
was probably raised from seeds at the Arnold Arboretum. 
FLABELLATAE. 
Stamens 5; anthers rose color. 
Crataegus ampla, n. sp. Leaves ovate, acuminate, rounded, 
truncate or rarely cuneate at the base, sharply often doubly serrate, 
with slender straight glandular teeth, and divided into 5 or 6 pairs 
of broad acuminate lateral lobes, slightly tinged with red and villose 
on the upper surface when they unfold, nearly half grown when the 
flowers open about the 20th of May and then membranaceous, light 
yellow-green and roughened above by short lustrous white hairs and 
pale and glabrous below, and at maturity thin, dark yellow-green and 
scabrate on the upper and paler on the lower surface, 6-7 cm. long 
and 5-6.5 cm. wide, with stout yellow midribs, and slender primary 
veins arching obliquely to the points of the lobes; petioles slender, 
nearly terete, glabrous, glandular near the apex, with occasional 
minute usually persistent glands, rose-colored in the autumn, 1.5-3 
cm. in length; stipules oblong-obovate, often falcate, glandular, 
fading brown, caducous; leaves on vigorous shoots truncate or 
slightly cordate at the base, more coarsely serrate and more deeply 
lobed, and 7-8 cm. long and broad. Flowers about 1.5 cm. in 
diameter, on slender elongated glabrous pedicels, in usually 7—10- 
flowered corymbs, with oblong-obovate to linear glandular rose-colored 
bracts and bractlets; calyx-tube broadly obconic, glabrous, the lobes 
wide, foliaceous, acuminate, coarsely laciniately serrate, glandular, 
with large dark red glands, glabrous on the outer, sparingly villose 
on the inner surface, spreading or reflexed after anthesis; stamens 5; 
anthers dark rose color; styles 3, surrounded at the base by a broad 
ring of hairy tomentum. Fruit ripening early in October, on slender 
drooping pedicels, in few-fruited clusters, obovate, rounded at the 
apex, gradually narrowed to the base, bright cherry red, lustrous, 
marked by small pale dots, about 1.2 cm. long and 1 cm. wide; calyx 
little enlarged, with a broad deep cavity and spreading appressed 
coarsely serrate lobes, their tips often deciduous from the ripe fruit; 
flesh thin, yellow, dry and mealy; nutlets 3, narrowed and rounded at 
the ends or acute at the apex, ridged on the back, with a broad high 
deeply grooved ridge, about 8 mm. long and 4-5 mm. wide. 
A shrub 4-5 m. high, with numerous stout ascending many- 
branched stems covered with dark gray bark and forming a broad 
round-topped compact head, and slender, slightly zigzag branchlets 
marked by small oblong pale lenticels, dark orange-green when they
