1. Crataegus Burkeana n. sp. 



Leaves ovate, acute or acuminate, abruptly cuneate or rounded 

 at the base, sharply often doubly serrate, with straight glandular 

 teeth, and slightly divided into 4 or 5 pairs of small acute lateral 

 lobes ; nearly half-grown when the flowers open about the 10th of May 

 and then thin, light yellow-green and roughened above by short white 

 hairs and paler and sparingly villose on the midribs and veins below, 

 and at maturity thin, yellow-green and scabrate on the upper surface, 

 nearly glabrous on the lower surface, 5-8 cm. long and 4.5-8 cm. wide, 

 with stout midribs, and thin prominent primary veins; petioles 

 slender, slightly wing-margined at the apex, densely villose early 

 in the season, becoming almost glabrous, 1.5-3 cm. in length; leaves 

 on vigorous shoots usually cordate at the broad base, more coarsely 

 serrate and more deeply lobed and often 8-10 cm. long and broad, with 

 thicker midribs and primary veins and stout glandular petioles. 

 Flowers 1.2-1.6 cm. in diameter, on short densely villose pedicels, in 

 small compact hairy mostly 5-10-flowered corymbs, the lower pedun- 

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

 slightly villose, the lobes long, slender, acuminate, coarsely glandular- 

 serrate, glabrous on the outer surface, villose on the inner surface, 

 reflexed after anthesis; stamens 5-8; anthers dark purple; styles
