to nearly 11 lines long, sharply and irregularly serrate to or below the middle, entire 

 or nearly so at the base, snore or less i»iibesceut when young, dark green and lus- 

 trous above, pale below, becoming thick and coriaceous; flowers nnuierous, large, 

 from 7 to 8 lines in diameter, disposed in slender, elongated, and often Hexnous, 

 bracteato corymbs, more or less hairy at dowering time; calyx narrow-obconic, 

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

 lobes redexed after liowering, the orbicular petals with undulate or erose borders; 

 stamens normally 20, styles 3 to 5; fruit globose, abont 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. n-KS-cjaUi L., or more recently 

 with ('. colliiia Chapm. From the former it may be distinguished by the pilose 

 corymbs, smaller aud 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 liowering, and smaller lustrous leaves. This beantiful 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 Centr.al Prairie belt. Reaches its best development 

 in the rich and fresh soil of Hat woods in the center of the State, but not infrequently 

 ascends into the poorer and drier soils of the mountains and liills. Flowers about 

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

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 

 ])ubescent branchlets, forming an oblong, occasionally rounded or tlat-top]ied 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, on the fertile branches from 1 to 4 inches long and from 



1 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 austromontaua 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 iinited 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, 1^ to 4 inches long, roughish-pubesr 

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

 sometimes subcordale base into the margined petiole, sharply irregularly serrate or 

 inciseh lobed, and ;it the base glandular like tlie iietioles; flowers large, in simple 



2 to rt flowered, 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 iu 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 

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