1922) SARGENT, NOTES ON NORTH AMERICAN TREES, X. 195 



paler below, 6-7 cm. long and 4-5 cm. wide, with a slender midrib and 

 primary veins; petioles slender, glabrous, occasionally glandular, 2.5-3 

 cm. in length; leaves on vigorous shoots, broad-ovate, rounded, truncate 

 or cordate at base, more deeply lobed and more coarsely serrate, 5-6 cm. 

 long and broad, with petioles only 1.5-2 cm. long. Flowers opening about 

 May 20, 1.5-1.7 cm. in diameter, on slender pedicels, in small compact 

 mostly 4-7-flowered glabrous corymbs with coarsely glandular-serrate 

 bracts and bractlets; calyx-tube broad-obconic, glabrous, the lobes separat- 

 ed by wide sinuses, short, broad, acuminate, tipped with a dark gland, 

 entire or obscurely glandular-serrate, glabrous; stamens 10; anthers pink, 

 styles usually 5. Fruit ripening early in October, subglobose but broader 

 than high, flattened at the ends, hard, green, 1-1.2 cm. in diameter, the 

 calyx sessile with a shallow cavity 5 or 6 mm. in diameter, the lobes 

 deciduous; flesh thin, hard and dry, nutlets 5, rounded at the ends, slightly 

 grooved on the back, 4 or 5 mm. long and wide, the pale hypostyle nearly 

 covering their inner faces. 



A tree 6 or 7 m. high, with a single small trunk covered with dark 

 gray bark, separating near the base in loose scales, ascending branches 

 forming an open head, and stout slightly zigzag glabrous branchlets 

 light yellow-green when they first appear, becoming dark chestnut-brown, 

 marked by pale lenticels and armed with numerous stout nearly straight 

 dark chestnut brown spines persistent and becoming compound on the 

 trunk and large branches. 



Ohio. Washington County, near Marietta, R. E. Horsey, No. 602 (type), 

 May 20 and September 30, 1917. 



From the other species of this group already described with depressed 

 globose fruit and a red shallow fruit calyx, this new species differs in the 

 shape of the leaves which are not cuneate at base as in those species, 

 but broad and rounded or truncate. 



Crataegus uvaldensis (§ Molles), n. sp. 



Leaves ovate, acute and short-pointed at apex, concave-cuneate at 

 base, slightly or on leading shoots more deeply lobed usually only above 

 the middle with short acuminate lobes, and deeply doubly serrate often 

 nearly to the base with slender acuminate gland-tipped teeth, covered 

 above when they unfold with short ridged pale hairs and pale and villose 

 below especially along the midrib and primary veins, and at maturity 

 thin, dark dull green and scabrate on the upper surface, pale and nearly 

 glabrous on the lower surface, 4-5 cm. long and 3-3.5 cm. wide, with a 

 slender slightly villose pale yellow midrib and primary veins; petioles 

 slender, slightly wing-margined at the apex by the decurrent base of the 

 blade, thickly covered early in the season with matted pale hairs, becoming 

 pubescent, 6-15 mm. in length; leaves on vigorous shoots more deeply 

 sometimes 3-lobed with large foliaceous coarsely and sharply serrate 

 stipules. Flowers opening early in April, about 1 cm. in diameter, on
