able that such a distinct and beautiful plant as C. de//u/a could if gen- 
erally distributed have escaped notice. 
Crataegus incisa, n. sp. Leaves ovate-oblong, acuminate, cune 
ate or rounded at the entire glandular base, sharply doublv serrate 
above, with straight or incurved glandular teeth, and deeply divided 
into numerous narrow acuminate spreading sometimes reflexed lateral 
lobes, more than half grown when the flowers open from the 2oth to 
the end of May and then membranaceous, light yellow green, smooth 
and glabrous above, and pale or glaucous and slightly hairy along 
the midribs and veins below, and at maturity subcoriaceous, dark 
blue-green and lustrous on the upper and pale-green on the lower 
surface, 5-8 cm. long and 4-6 cm. wide, with prominent yellow mid- 
ribs, and slender obscure primary veins arching obliquely to the points 
of the lobes; petioles slender, slightly wing-margined at the apex, 
nearly terete, yellow, sometimes glandular while young, with minute 
dark red deciduous glands, 2-3 cm. in length; leaves on vigorous 
shoots ovate, truncate or rounded at the broad base, coarsely serrate, 
3-lobed by deep narrow sinuses, the terminal lobe incisely lobed, 
coriaceous, 7—9 cm. long and wide, with stout winged conspicuously 
glandular petioles, and foliaceous lunate long-pointed laciniately di- 
vided stipules. Flowers 1.8—2 cm. in diameter, on slender elongated 
glabrous pedicels, in lax 4-6-flowered corymbs, with linear acuminate 
glandular bracts and bractlets, fading brown and mostly deciduous 
before the flowers open ; calyx-tube narrowly obconic, glabrous, the 
lobes gradually narrowed from wide bases, acute and glandular at 
the apex, entire or finely glandular-serrate near the middle, glabrous, 
reflexed after anthesis; stamens s-ro ; anthers pale rose color; 
styles usually 3, surrounded at the base by a narrow ring of pale hairs. 
Fruit ripening late in October, and persistent until after the fall of 
the leaves on erect or spreading pedicels, in compact few-fruited 
clusters, obovate, full and rounded at the apex, gradually narrowed 
to the base, green covered with a glaucous bloom, late in the season 
often becoming crimson or tinged with crimson, r.3—1.5 cm, long and 
1—1.2 cm. wide; calyx little enlarged, without a tube, and with a nar- 
row shallow cavity and spreading lobes, their tips often deciduous 
from the ripe fruit; flesh thin, hard and green ; nutlets 3, gradually 
narrowed to the rounded ends, ridged on the back, with a broadly 
grooved ridge, about 8 mm. long and 5 mm. wide. 
A shrub or small tree 3-4 m. high, with slender stems, and stout 
slightly zigzag branchlets marked by small dark lenticels, green 
tinged with red when they first appear, soon becoming bright red- 
brown and very lustrous, and dark dull gray-brown in their second 
year, and armed with slender straight or slightly curved shining 
spines 3.5—5 cm. long.
