to nearly 11 lines long, sharply and irregularly serrate to or below the middle, entire 
or nearly so at the base, more or less pubescent when young, dark green and lus- 
trous above, pale below, becoming thick and coriaceous; flowers numerous, large, 
from 7 to 8 lines in diameter, disposed in slender, elongated, and often flexuous, 
bracteate corymbs, more or less hairy at flowering time; calyx narrow-obconie, 
mostly glabrous, with linear-lanceolate, mostly entire or slightly glandular-serrate 
lobes retlexed after flowering, the orbieular petals with undulate or erose borders; 
stamens normally 20, styles 3 to 5; fruit globose, about 4 lines in diameter, dark red 
or greenish red or covered with black blotches; nutlets 3 to 5, thick-walled. 
Crataegus mohri has usually been confounded with C. erus-galli L., or more recently 
with C. collina Chapm. From the former it may be distinguished by the pilose 
corymbs, smaller and more globular fruit, and more numerous and smaller nutlets, 
and by the outline of the leaf and habit of growth, and from the latter by the later 
time of flowering, and smaller lustrous leaves. This beautiful and most distinct 
species is dedicated to Dr. Charles Mohr, of Mobile, Ala. (Beadle. ) 
Carolinian area, Mississippi northward to middle Tennessee. 
ALABAMA: Mountain region toCentral Prairie belt. Reaches its best development 
in the rich and fresh soil of flat woods in the center of the State, but not infrequently 
ascends into the poorer and drier soils of the mountains and hills. Flowers about 
Ist of May; fruit ripens in October, remaining until early in the winter.

Crataegus triflora Chapm. Fl. ed. 2, Suppl. 2, 681. 1892. 
Chapm. FI. ed. 3, 139. 
A large shrub or small tree from 6 to 20 feet high, with the main stem simple or 
branching near the base into several shoots, armed with numerous spines, the 
branches ascending, intricately divided near the summit into many short pilose or 
pubescent branchlets, forming an oblong, occasionally rounded or flat-topped head. 
Leaves at first thin, dark green above, paler beneath, somewhat roughish and 
sparsely pubescent on the upper surface, more densely so below, ovate, elliptical, or 
slightly obovate, acute at the apex, rounded or abruptly contracted at the base into 
winged or argined petioles, ou the fertile branches from 1 to 4 inches long and from 
Linch to 2 inches wide, on vigorous shoots 5 and 6 inches long and about 3 inches 
wide, sharply and irregularly serrate, or doubly serrate and incisely lobed, with a 
number of black-tipped glands near the base, as also on the petiole; stipules lanceo- 
late, densely glandular, caducous; flowers } inch wide, in mostly 3-flowered, pilose, 
sottly pubescent corymbs, the lateral pedicels longer; calyx densely pilose, with per- 
sistent glandular-serrate lobes twice as long as the tube; stamens 20; styles 3 to 5; 
fruit globose, 6 to 7 lines in diameter, pubescent, bright red, 
Carolinian area. Northwestern Georgia. 
ALABAMA: Mountain region to Lower hills. Rocky hills, Jefferson County, Bir- 
mingham (C. 1. Boynton). DeKalb County? Flowers early in May; fruit ripe in

Type locality: ‘Clifis of the Coosa River, Georgia.” 
Crataegus austromontana Beadle, Bot. Gaz, 28:412. 1899. 
A straggling shrub 3 to 12 feet high, two or three main stems arising from large 
roots or horizontal rootstocks, or forming more or less united groups or clumps, 
occupying a surface of 5 to 10 square feet, the branches unarmed or with an occa- 
sional spine on a young plant or vigorous shoot, the branchlets pubescent or 
tomentose. Leaves orbicular or broadly ovate, 1} to 4 inches long, roughish-pubes- 
cent on both surfaces, acute at the apex, contracted at the rounded truncate or 
sometimes subecordate base into the margined petiole, sharply irregularly serrate or 
incisely lobed, and at the base glandular like the petioles; flowers large, in simple 
2 to 5 tlowered, mostly 3-flowered cymes, borne on stout hairy pedicels from ¢ to 1 
inch long; stamens 10; styles 3 to 5; calyx pubescent, broad with glandular-serrate 
lobes; fruit large, } inch or a little over in diameter, bright red, and frequently 
punetate, containing 3 to 5 bony uutlets. 
Close to C. triflora, but may, as stated by the author, be recognized by its smaller 
size, broader leaves, fewer stamens, and the larger and coarser seeds, 
Carolinian area. Eastern and middle Tennessee (Cumberland district). 
ALABAMA: Mountainregion, Rocky woods and banks throughont the Sand Moun-

A tree in low and moist woods, from 18 to 30 feet high, with the trunk sometimes
