On the Shafer farm in Moor Township, west of Carnot, in Alle- 

 gheny County, J. A. Shafer, May 20 and October 8, 1901, May 18 and 

 20 and October 26, 1902. 



Mr. Ashe has described the leaves as "at first villose on the petioles 

 and midrib above and veins beneath," but the leaves of Shafer's 

 specimens from which my description has been drawn are entirely 

 glabrous even when they are unfolding. 



Crataegus Shafer i is near Cratcegus cognata Sarg., but differs from 

 that species in the broader leaves of the young shoots, in its sub- 

 globose not obovate fruit, and by the much larger clayx of the fruit. 

 22. Crataegus bedfordensis n. sp. 



Glabrous with the exception of a few hairs on the upper surface 

 of the young leaves. Leaves ovate, acute or acuminate, rounded or 

 broadly cuneate at the entire sometimes unsymmetrical base, finely 

 doubly serrate above, with minute straight or incurved glandular 

 teeth, and very slightly divided above the middle into 2 or 3 pairs 

 of small acute spreading lobes; when they unfold slightly tinged with 

 red and sparingly hairy above, with deciduous hairs, nearly half- 

 grown and almost glabrous when the flowers open the middle of May 

 and then thin, light yellow-green, smooth and lustrous above and 

 paler below, and at maturity dark yellow-green and lustrous on the 

 upper surface, dull bluish green on the lower surface, 3-4 cm. long 

 and 2-2.8 cm. wide, with thin yellow midribs and primary veins; 

 petioles slender, glabrous while young, with minute stipitate deciduous 

 glands, 1.5-2 cm. in length; leaves on vigorous shoots broadly ovate, 

 rounded at the wide base, 3.5-4 cm. long and broad. Flowers 1.5 cm. 

 in diameter, on long slender pedicels, in 4-8-, usually 5-flowered 

 corymbs, with oblong-obovate to linear glandular-serrate rose-colored 

 bracts and bractlets often persistent until the flowers open, the elon- 

 gated lower peduncles from the axils of upper leaves; calyx-tube 

 narrowly obconic, the lobes gradually narrowed fron the base, short, 

 broad, acuminate, entire or occasionally minutely dentate near the 

 middle, reflexed after anthesis; stamens 20; anthers white; styles 3 or 

 4, surrounded at the base by a narrow ring of pale tomentum. Fruit 

 ripening in October, on slender pedicles, in few-fruited drooping 

 clusters, short-oblong to slightly obovate, full and rounded at the 

 ends, green and pruinose when fully grown, turning pale red, marked 

 by small dark dots, 8-10 mm. in diameter; calyx little enlarged, with 

 a short tube, a broad shallow cavity wide in the bottom, and small 

 spreading and reflexed lobes; flesh thin, green and firm; nutlets 3 or 4, 

 gradually narrowed and rounded at the ends, rounded and slightly
