moreland County, (No. 86) O. E. Jennings, September 21, 1907; 

 rich hillsides, Bedford, Bedford County, B. H. Smith and C. S. Sargent, 

 (No. 301) September 30, 1905, B. H. Smith, May 18, 1906. 



The leaves of the Bedford County plant are usually acuminate, or 

 they are acute and do not show on the specimens collected by Mr. 

 Smith any tendency to become broad and rounded at the apex — a 

 form which is not uncommon on trees in the neighborhood of Pittsburg. 

 The young leaves of the Bedford County plants are slightly more hairy 

 along the upper side of the midribs, and the spines are rather lighter 

 colored. Otherwise they appear identical with the type of the species. 



3. Crataegus recedens n. sp. 



Leaves broad obovate to orbicular-obovate or rarely elliptical, 

 acute or acuminate and often abruptly pointed at the apex, gradually 

 narrowed to the cuneate or rarely rounded entire often unsymmetrical 

 base, sharply doubly serrate above, with straight glandular teeth, and 

 slightly divided above the middle into 4 or 5 pairs of slender acuminate 

 spreading lobes ; more than half grown when the flowers open about 

 the 20th of May and then thin, yellow-green, roughened above by 

 numerous white hairs and sparingly villose on the midribs and veins 

 below, and at maturity thin, dull deep yellow-green, smooth and 

 glabrous or occasionally scabrate above and pale and still slightly 

 villose below on the thin prominent midribs and 6 or 7 pairs of thin 

 primary veins extending obliquely toward the apex of the leaf, 4.5- 

 5.5 cm. long and 3.5-4.5 cm. wide; petioles slender, wing-margined 

 at the apex, villose early in the season, becoming nearly glabrous, 

 1.5-3 cm. in length; leaves on vigorous shoots more coarsely serrate 

 and more deeply lobed and often 7-8 cm. long and broad. Flowers 

 1.8-2.2 cm. in diameter, on long stout slightly hairy pedicels, in broad 

 5-15-flowered corymbs, the lower peduncles from the axils of upper 

 leaves; calyx-tube broadly obconic, glabrous, the lobes gradually 

 narrowed from wide bases, long, acuminate, minutely glandular- 

 serrate below the middle or entire, glabrous on the outer, sparingly 

 villose on the inner surface, reflexed after anthesis; stamens 18-20; 

 anthers pink ; styles 3-5. Fruit ripening early in October, on slender 

 glabrous or slightly hairy erect or spreading pedicels, in few-fruited 

 clusters, nearly globose, sometimes slightly tapering toward the 

 base, dark red more or less blotched with green or russet green, hardly 

 punctate, glabrous or rarely puberulous, 1.1-1.5 cm. in diameter; 

 calyx prominent, with a long tube, a wide deep cup-shaped cavity, 

 and elongated reflexed persistent lobes hairy on the upper surface;
