which ai)pear the first or second week in June, when the leaves are 

 nearly full grown, in large many-flowered compound glabrous corymbs, 

 are about 17 mm. wide and on slender nodding pedicels; calyx nar- 

 rowly obconic, glabrous, the narrow triangular lobes entire ; stamens 

 8-10, slender, anthers white ; styles 1-2. The fruit, which ripens 

 early in October, in large compound clusters on drooping pedicels, is 

 subglobose, about 13 mm. thick, dull dark red, and capped by the 

 persistent spreading lobes ; flesh hard, green, or white ; seeds oblong, 

 generally 2, the backs rounded. 



Separated from the other eastern plants which have been associated 

 under the name of C. cn/s-gal/i by the white anthers and broader foli- 

 age. Probably common throughout the mountains from eastern Ten- 

 nessee to Pennsylvania. W. W. Ashe, Glade Springs, Virginia ; J.

Crat.egus virella n. sp. A shrub forming thickets 3-5 m. in 

 height with numerous ascending stems and slender dark brown twigs 

 armed with numerous slender chestnut brown thorns 4-^ cm. long. 

 Leaves firm, dark green and glabrous above, iiiuch paler and rough 

 pubescent beneath especially on the veins, often nearly glabrous at 

 maturity, ovate or broadly ovate, 4-6 cm. long, 3-5 cm. wide, 

 rounded or cuneate at the base, acute at apex, sharply and coarsely 

 serrate, 2-3 pairs of shallow notches, 3-4 pairs of prominent veins ; 

 petiole 2-3 cm. long, broadly winged above by the decurrent blade. 

 The flowers which appear the last of May, in nearly simple few- 

 flowered pubescent or nearly glabrous cymes, are about 17 mm. 

 wide ; calyx-lobes broadly triangular, serrulate, ascending after 

 anthesis, stamens 20 ; styles 3-5. The fruit, borne in simple, 2- 

 5-fruited clusters, on erect or ascending nearly or (juite glabrous 

 pedicels, is depressed globose, concave at base, flattened at the apex, 

 about 1.2 cm. long, 1.3 cm. thick, more or less angled by the seed, 

 glabrous, sparingly pruinose, yellowish green, blotched with pink, 

 olive or russet, capped by the short erect calyx-lobes ; flesh firm, 

 hard, green and bitter; seeds usually 5, 6-7 mm. long, scarcely 

 grooved on the back ; cavity broad and deep. The fruit ripens in Oc- 

 tober and falls after the leaves, some of it persistent until November. 



C. virella is probably most closely related to C. pruinosa Wend, 

 from which it is separated by its smaller size, depressed green fruit 

 and pubescence. Fields and banks, Berks county, Pennsylvania, C.
