from Michigan to Nebraska and Missouri. Crataegus submodé/is differs from 
that species in its smaller and less deeply lobed cuneate leaves, which are 
not truncate or cordate even on vigorous leading shoots; in its ten, not 
twenty, stamens ; smaller, less downy fruit on much longer, more slender and 
drooping peduncles ; in its more zigzag orange-colored branchlets, those of 
Crataegus mollis being of a bright chestnut-brown color during the first sum- 
mer ; longer and much more numerous spines ; and in its smaller size. 
Crataegus dilatata, n. sp.— Leaves ovate from a broad, trun- 
cate, cordate, or slightly rounded base, coarsely irregular glan- 
dular-serrate, unequally lobed usually with two or three pairs of 
acute lateral lobes, membranaceous, with slender midribs and 
four or five pairs of thin primary veins, when the flowers open 
roughened on the upper surface with short ridged white hairs, 
light yellow-green, and conspicuously plicate, at maturity dark 
green, 2 to 2% in. long, usually as wide as long, and on vigor- 
ous leading shoots often 4 to 4% in. long and usually rather 
broader than long; petioles slender, terete, glandular, at first 
more or less villous but soon glabrous, 1 to 1% in. long, dark 
red toward the base; stipules linear-lanceolate and on vigorous 
shoots lunate and foliaceous, glandular with dark red glands, 
% in. long, caducous, Flowers 1 to 1% in. in diameter when 
expanded, in broad, open, nearly glabrous, villous or tomentose 
compound cymes, the bracts and bractlets, like the bud-scales, 
glandular with stalked red glands; calyx villous with soft white 
deciduous hairs, the cup broad and shallow; calyx-lobes broad, 
acuminate, coarsely glandular-serrate, much enlarged and spread- 
ing on the fruit, and bright red on the upper surface below the 
middle ; stamens 20; filaments slender, elongated ; anthers large, 
rose color; styles usually five, surrounded at the base by small 
tufts of white hairs. Fruit subglobose with sweet, yellow, thick 
flesh, 34 in. in diameter, bright scarlet, punctuate with minute 
dark spots; nutlets five, comparatively small, prominently 
ridged on the back, about ¥% in. long. 
A tree sometimes 20 feet in height, with a tall straight 
trunk, wide-spreading branches forming a broad round head, or 
bushy with numerous spreading stems and slender, glabrous, 
slightly zigzag branchlets marked with large pale lenticels, at first
