EOSE FAMILY. 549 



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-obconic, 

 mostly glabrous, with linear-lanceolate, mostly entire or slightly glandular-serrate 

 lobes reflexed after flowering, the orbicular 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. crus-galli L., or more recently 

 with C. coUina Chapm. From the former it may be distinguished by the pilose 

 corymbs, smaller ami more globular fruit, and more numerous and smaller nutlets, 

 and by the outline of the loaf 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 to Central 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 

 1st of May; fruit ripens in October, remaining until early in the winter.

Crataegus triflora Chapm. Fl. ed. 2, Suppl. 2, 684. 1892. 



Chapm. Fl. 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 margined petioles, ou the fertile branches from 1 to 4 inches long and from 

 | inch 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, 

 softly 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.

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 

 tomeutose. Leaves'orbicular or broadly ovate, H to 4 inches long, roughish-pubes- 

 cent on both surfaces, acute at the apex, contracted at the rounded truncate or 

 sometimes subcordaf e 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 flowered, mostly 3-flowered cymes, borne on stout hairy pedicels from f 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 

 punctate, containing 3 to 5 bony nutlets. 



Close to C. triflora, but may, as stated by the author, be recognized by its smaller 

 sixe, broader leaves, fewer stamens, and the larger and coarser seeds. 



Carolinian area. Eastern and middle Tennessee (Cumberland district).
