ters, obovoid until nearly fully grown, becoming short-oblong when fully ripe, rounded at 

 the ends, bright scarlet, lustrous, marked by numerous small dark dots, f long, and -o'-f 

 in diameter; calyx large and conspicuous, the lobes much enlarged, coarsely serrate, and 

 usually erect and incurved; flesh pale, thin, dry and mealy; nutlets 5, narrowed and acute 

 at the ends, rounded and deeply grooved on the back, about |' long. 



A tree, 18-20 high, w f ith a tall trunk sometimes a foot in diameter, covered with close 

 red-brown scaly bark, long comparatively slender spreading or ascending branches 

 forming a handsome symmetrical head, and thin branchlets dark chestnut-brown and 

 slightly villose at first, becoming very lustrous and ashy gray in their second year, and 

 armed with straight or slightly curved shining chestnut-brown spines l|'-2' long. 



Distribution. Central and western New York to western Pennsylvania (Allegheny and 

 Crawford counties), and to southern Ontario to the neighborhood of Toronto and London; 

 common; passing into var. gloriosa Sarg. differing in its rather larger flowers with pink 

 anthers, larger and more lustrous fruit often mammillate at base and ripening a few days 

 earlier and in its convex leaves. A tree, 20-25 [high, with a trunk often 1 in diameter, 

 and a symmetrical round-topped head; Rochester, Munroe County, New York; not 



100. Crataegus Holmesiana Ashe. 



Leaves oval or ovate, acute or acuminate at apex, rounded or broad-cuneate at base,

minate lateral lobes, when they unfold dark red, roughened by rigid pale hairs on the upper

 green and nearly half grown when the flowers open early in May, and at maturity thick 

 and firm, almost smooth, conspicuously yellow-green, usually about 2' long and If wide, 

 with a prominent midrib often bright red on the lower side tow r ard the base, and 4-6 pairs 

 of slender primary veins arching to the point of the lobes; petioles slender, nearly terete, 

 glandular, glabrous or sometimes puberulous while young, I'-l^' in length; leaves at the 

 end of vigorous shoots often broad-ovate to oval, rounded, truncate or slightly cordate at 

 base, more coarsely serrate and more deeply lobed, and frequently 4' long and 3' wide. 

 Flowers cup-shaped, \'-\' in diameter, on long slender glabrous pedicels, in loose 

 glabrous or rarely puberulous many-flowered corymbs, with oblanceolate or linear acute 

 glandular caducous bracts and bractlets; calyx-tube narrowly obconic, glabrous, more or 

 less deeply tinged with red, the lobes long, acuminate, glandular-serrate, or often nearly
