1903] Sargent,— Recently Recognized Species of Crataegus 151 
full and rounded at the broad base, coarsely serrate, more deeply 
lobed than the leaves on lateral branchlets, often 7-8 cm. long and 
nearly as wide. Flowers 1.3—1.4 cm. in diameter on slender pedicels, 
in small usually 5 or 6-flowered thin-branched compact corymbs ; 
bracts and bractlets linear, acute, glandular-serrate, caducous ; calyx- 
tube broadly obconic, the lobes slender, acuminate, entire or rarely 
sparingly serrate above the middle, tipped with minute red glands, 
reflexed after anthesis; stamens 5-8 ; anthers light rose color; styles 
3-5, surrounded at the base by a broad ring of pale tomentum. Fruit 
in few-fruited drooping clusters, obovate, full and rounded at the 
apex, gradually narrowed from above the middle to the slender base, 
bright scarlet, 1.4-1.8 cm. long, 1-1.4 cm. wide; calyx enlarged, 
sessile with a broad shallow cavity and reflexed closely appressed 
lobes often slightly dentate toward the apex, bright red on the upper 
side at the base, mostly persistent ; flesh thick, sweet, nearly white, 
dry and mealy; nutlets 3-5, thick or thin according to their number, 
acute at the ends, rounded and prominently ridged on the back, with 
a high rounded ridge, about 8 mm. long. 
An arborescent shrub 3-4 m. in height with erect branches and 
slender slightly zigzag branchlets, light yellow-green when they first 
appear, dull dark red-brown and marked by occasional large oblong 
pale lenticels during their first season, orange color and rather lus- 
trous the following year, and armed with numerous slender slightly 
curved dark purple shining spines 4-6 cm. in length. Flowers dur- 
ing the last week of May. Fruit ripens early in October.

This interesting species with its small flowers in few-flowered 
corymbs, small number of stamens, leaves at first hairy on the upper 
surface but dark green and subcoriaceous at maturity, and pear- 
shaped fruits without bloom or a calyx-tube, appears intermediate 
between the Zenutfolia and Pruinosa sections of the genus and 
might be referred with equal propriety to either.

Crataegus Forbesae, n. sp. Leaves ovate to oval, acuminate, 
gradually narrowed and rounded or broadly concave-cuneate at the 
mostly entire base, serrate, often doubly with small straight or incurved 
glandular teeth, and slightly divided into 3 or 4 pairs of short acute 
lateral lobes; tinged with red when they unfold and coated above 
until after the flowers open with short soft pale hairs, at maturity 
dull dark bluish green and glabrous on the upper surface, paler on
