the end of vigorous shoots often 4 '-5' long, and frequently rather broader than long. Flow- 

 ers I'-lf in diameter, on slender elongated hairy pedicels, in broad, loose, usually 8-12- 

 flowered slightly villose corymbs, with lanceolate bracts and bractlets glandular like the 

 inner bud-scales with dark red glands; calyx-tube broadly obconic, covered toward the 

 base with matted pale hairs, nearly glabrous above, the lobes broad, acuminate, coarsely 

 glandular with large scattered red glands, glabrous on the outer surface and generally 

 slightly villose on the inner surface; stamens 20; anthers large, rose color; styles usually 5, 

 surrounded at base by small tufts of white hairs. Fruit ripening and falling early in Sep-

spreading coarsely serrate lobes bright red on the upper side toward the base; flesh thin, 

 sweet and yellow; nutlets 5, thin, rounded and prominently ridged on the back, about J' 

 long. 



A tree, occasionally 20 high, with a tall straight trunk, covered with light gray-brown

Leaves nearly orbicular to oval or rarely to oblong, short-pointed at apex, broad and 

 rounded or broad-cuneate at the entire base, sharply doubly serrate above with slender 

 straight or incurved glandular teeth, and often divided above the middle into 3 or 4 pairs of 

 short acute lobes, when they unfold pale yellow-green and somewhat villose on the upper 

 surface toward the base and below in the axils of the principal veins, about a third grown 

 when the flowers open during the first week of June, and at maturity thin and firm in tex- 

 ture, dull dark green above, paler below, usually about 1%' long and broad, with a slender 

 midrib and 4 or o pairs of thin primary veins; petioles slender, slightly glandular, more or 

 less winged above, f '-!' in length; leaves at the end of vigorous shoots nearly orbicular to 

 oval, more coarsely serrate and more deeply lobed, and frequently 3' long and wide, their 

 petioles often broadly winged and conspicuously glandular. Flowers i' in diameter, on 

 short stout pedicels, in compact 6-12-flowered glabrous corymbs; calyx broadly obconic, 

 the lobes gradually narrowed from a broad base, long, acuminate, entire or occasionally
