thick yellow midribs and 5 or 6 pairs of slender primary veins extend- 
ing obliquely to the points of the lobes; petioles stout, narrowly wing- 
margined to the middle, puberulous while young. deeply grooved on 
the upper side, 1-2 cm. long; leaves on vigorous shoots oblong- 
obovate, more coarsely serrate, slightly lobed, often 8-9 cm. long 
and 5-6 cm. wide, with stout petioles about 3 cm. in length. Flow- 
ers 1.2-1.4 cm. in diameter, on long slender glabrous pedicels, in 
loose lax 15-20-flowered compound corymbs; calyx-tube narrowly 
obconic, glabrous, the lobes wide, acuminate, glandular-serrate, vil- 
lose on the outer and covered on the inner surface with matted 
pale hairs, reflexed after anthesis; stamens 9—11, usually 10; anthers 
pale pink; styles 1-3. Fruit ripening from the first to the middle of 
September and remaining on the branches until after the leaves have 
fallen, on long drooping pedicels, in many-fruited clusters, ovate, 
rounded at the apex, nearly truncate at the base, red or greenish 
red, 9-10 mm. long and wide; calyx little enlarged, with a deep nar- 
row cavity, and closely appressed lobes red below the middle and 
villose on the upper side, and often deciduous from the ripe fruit ; 
flesh thin, dry and yellow; nutlets 2 or 3, full and rounded at the 
base, gradually narrowed and rounded at the apex, rounded and 
ridged on the back, with a low broad ridge, penetrated on the inner 
faces by long narrow cavities, about 6 mm. long and 4 mm. wide. 
A shrub 2—5 m. high, with numerous stems 5-7 cm. in diameter 
near the ground and covered with gray-brown bark, the lower 
branches horizontally spreading, the upper ascending, and slender 
slightly zigzag branchlets marked by occasional oblong pale lenticels, 
dark orange-green and glabrous when they first appear, becoming 
bright chestnut-brown and very lustrous in their first season and 
dull gray brown the following year, and armed with slender slightly 
curved red-brown shining spines 6—8 cm. long.

Crataegus Bristolensis, n. sp. Leaves ovate to rhombic, acute 
or acuminate, gradually narrowed and concave-cuneate at the entire 
base, finely doubly serrate above, with straight glandular teeth, and 
divided into 4 or 5 pairs of small acuminate lateral lobes, nearly half 
grown when the flowers open about the middle of May and then 
membranaceous, light yellow-green and roughened above by short 
rigid white hairs and glaucous below, and at maturity thin but firm 
in texture, smooth, yellow-green and lustrous on the upper and paler 
on the lower surface, 7-8 cm. long, 5-6 cm. wide, with stout midribs 
and slender primary veins arching obliquely to the points of the lobes;
