coarsely serrate and more deeply lobed and often 3-8 cm. long and 
broad. Flowers 2-5 cm. in diameter, on long stout glabrous pedicels, 
in generally 5—12-flowered broad lax corymbs, the lower branches 
from the axils of upper leaves; calyx broadly obconic, glabrous, 
tinged with red, the lobes gradually narrowed, short-acuminate, 
finely glandular-serrate above the middle, green, glabrous on the 
outer, sparingly villose on the inner surface, reflexed after anthesis ; 
stamens 20; anthers large, pale rose color; styles 5. Fruit ripening 
in September, on stout erect pedicels, in few-fruited clusters, subglo- 
bose to short-oblong, bright apple-green (September roth), about 1 
cm.in diameter; calyx prominent, with a wide deep cavity and small 
spreading and reflexed lobes hairy on the upper side and mostly per- 
sistent; flesh thin, green, dry and mealy ; nutlets 5, full and rounded 
at the base, acute at the apex, rounded or occasionally obscurely 
ridged on the back, dark-colored, about 7 mm. long and 5-6 mm. 
wide. 
A tree about 5 m. high, with a short trunk 20-25 cm. in diameter, 
covered with pale gray scaly bark, large spreading and ascending 
branches forming a wide open irregular head, and slender nearly 
straight branchlets marked by oblong pale lenticels, glabrous and 
deeply tinged with red when they first appear, soon becoming light 
orange-brown, light gray tinged with red in their second year, and 
armed with numerous slender nearly straight bright chestnut-brown 
shining spines 3.5-4.5 cm. long, elongated, much-branched, and very 
abundant on the trunk and branches.

Crataegus fusca, n. sp. Leaves ovate, acuminate, rounded, 
cuneate or almost truncate at the broad entire base, sharply often 
doubly serrate above, with straight glandular teeth, and divided into 
4-6 pairs of narrow acuminate spreading lobes, nearly one-third 
grown when the flowers open about the rst of June and then thin, 
yellow-green slightly tinged with red, and glabrous with the excep- 
tion of a few scattered pale caducous hairs above and pale and gla- 
brous below, and at maturity thin, bluish green and lustrous on the
