1922J SARGENT, NOTES ON NORTH AMERICAN TREES. X. 191 



base, slightly dentate, glabrous on the outer surface, villose on the inner 

 surface, usually deciduous from the ripe fruit; stamens 20; anthers pale 

 yellow; styles 4 or 5. Fruit ripening early in October, subglobose, scarlet, 

 7-8 mm. in diameter, with thin dry flesh, the calyx little enlarged, with 

 a wide deep cavity broad in the bottom; nutlets 4 or 5, rounded at the ends, 

 rather broader at apex than at base, only slightly grooved on the back, 

 the wide hypostyle extending to the middle. 



A tree 4-5 m. high, with a slender stem covered with close gray bark, 

 separating into small scales, erect dark gray branches and slender straight 

 or slightly zigzag branchlets thickly covered when they first appear 

 with matted white hairs, becoming glabrous and reddish brown in their 

 first season and ashy gray the following year, and armed with numerous 

 nearly straight or slightly curved ashy gray spines. 2-3.5 cm. in length. 



Texas. Fort Bend County, rich prairies near Duke, E. J. Palmer, Nos. 

 5082 (3) (type), and 6894 (3). 



From related species this little tree can be distinguished by the often 

 nearly orbicular or occasionally slightly 3-lobed leaves on vigorous branch- 

 lets and by the small loosely attached scales of the bark of the trunk. 



Crataegus antimima (§ Virides), n. sp. 



Leaves ovate, elliptic or rarely obovate, acute or acuminate at apex, 

 abruptly or acutely cuneate at base, finely doubly serrate above the middle 

 with straight teeth and slightly lobed with acute lateral lobes; covered 

 above when they unfold with short caducous white hairs and usually 

 furnished below with axillary tufts of white pubescence, and at maturity 

 thin, yellow-green and lustrous on the upper surface, dull and paler on 

 lower surface, 3-4 cm. long and 2.5-3 cm. wide, with a thin midrib and 

 primary veins impressed above; petioles slender, slightly wing-margined 

 at apex, thickly coated until after the flowers open with matted white 

 hairs, becoming glabrous, 5-12 mm. in length; leaves on vigorous shoots 

 oblong to ovate or obovate, more coarsely serrate and usually more deeply 

 lobed, up to 6-7 cm. long and 4-4.5 cm. wide. Flowers opening late in 

 March or early in April, 2 cm. in diameter, in small compact usually 

 7-12-flowered glabrous corymbs; calyx-tube broad-obconic, glabrous, the 

 lobes abruptly narrowed from a broad base, slender, acuminate, entire, 

 glabrous, often deciduous from the ripe fruit; stamens 20; anthers pink, 

 styles 5, surrounded at base by a conspicuous ring of white tomentum. 

 Fruit ripening early in October, on slender pedicels in drooping clusters, 

 subglobose to slightly obovoid, dark orange-red, 7-8 mm. in diameter; 

 with thin soft flesh, the calyx little enlarged, with a narrow cavity not 

 contracted in the bottom; nutlets 5, rounded at the ends, broader at apex 

 than at base, only slightly grooved on the back, 4-5 mm. long, 2.5-3 mm. 

 wide, the narrow hypostyle extending to the middle. 



A shrub 4-5 m. high, with stems covered with dark slightly scaly bark, 

 small erect dark gray branches, and slender nearly straight branchlets
