crowded very compact 10-22-flowered corymbs, the lower peduncles 

 from the axils of upper leaves; calyx-tube narrowly obconic, the lobes 

 glandular-serrate, villose on the inner surface, reflexed after anthesis; 

 stamens 10-15; anthers rose color. Fruit ripening at the end of 

 September, on long drooping glabrous pedicels, in many-fruited 

 clusters, subglobose to ovate, full and rouucled at the ends, crimson, 

 lustrous, marked by large pale dots, 1.2-1.4 cm. in diameter; calyx 

 little enlarged, with a deep narrow cavity, and small spreading serrate 

 lobes villose on the upper side; flesh yellow, soft and succulent, nutlets 

 2 or 3, gradually narrowed and rounded at the ends, ridged on the 

 back, with a broad high deeply grooved ridge, only slightly penetrated 

 on the inner face, by short narrow cavities, 5.5-6 mm. long and about 

 4 mm. wide. 



A handsome tree 3-4 m. high, with a short trunk covered with 

 dark scaly bark, large spreading and ascending branches forming a 

 broad symmetrical head, and stout slightly zigzag branchlets, light 

 chestnut-brown and marked by small dark lenticels in their first 

 season and dull gray-brown the following year, and armed with num-

 8. Crataegus diaphora n. sp. 



Leaves obovate to oval, acute and often short-pointed at the apex, 

 gradually narrowed and cuneate and entire at the base, finely often 

 doubly serrate above, with straight glandular teeth, and occasionally 

 slightly divided above the middle into 2 or 3 pairs of small acute 

 lobes; nearly fully grown when the flowers open about the 10th of 

 June and then thin, light yellow-green, smooth, lustrous, and slightly 

 hairy along the midribs above and pale and slightiy hairy in the axils 

 of the leaves below, and at maturity thick, yellow-green, glabrous 

 and lustrous on the upper surface, pale and still slightly hairy on the 

 lower surface, 4-5 cm. long and 3.5-4 cm. wide, with thin midribs 

 and primary veins; petioles slender, slightly wing-margined often to 

 the middle, 1-1.5 cm. in length; leaves on vigorous shoots thicker, 

 oval to obovate, more coarsely serrate and often 6-7 cm. long and 5-6 

 cm. wide, with stout broadly winged rose-colored petioles. Flowers 

 1.8 cm. in diameter, on long slender glabrcms or occasionally slightly 

 hairy pedicels, in wide lax many-flowered corymbs, the lower pedun-
