fruited drooping clusters, depressed-globose, red; flesh thin, yellow, dry and mealy; 

 calyx enlarged, the lobes conspicuously serrate, puberulous on the upper surface, 

 reflexed and closely appressed, sometimes deciduous from the ripe fruit; nutlets 5, 

 thin, narrowed and rounded at the base, acute at the apex, rounded and obscurely 

 grooved on the back, about -fa' long. 



A tree, sometimes 20 high, with a trunk S'-KX in diameter, heavy wide-spreading

Leaves ovate to oval, concave-cuneate or rounded at the narrow base, sharply 

 doubly serrate above, with straight glandular teeth, and slightly divided into 3 or 4 

 pairs of narrow acuminate lateral lobes, unfolding with the opening of the flowers at 





the end of April or early in May and then light yellow-green tinged with bronze 

 color, lustrous and covered above with short shining caducous white hairs and hoary- 

 tomentose below, and at maturity membranaceous, light yellow-green and scabrate 

 on the upper surface, paler and pubescent on the lower surface, particularly along 

 the slender midribs and 4 or 5 pairs of thin primary veins extending obliquely to the 

 points of the lobes, 1'-2|' long, l'-2' wide; their petioles slender, more or less wing- 

 margined at the apex, villose early in the season, pubescent in the autumn. Flowers 

 1' in diameter, on short stout pedicels covered with matted pale hairs, in 3-10-flow- 

 ered compact compound or rarely simple villose corymbs; calyx-tube broadly ob- 

 conic, covered with matted pale hairs, the lobes glabrous, narrowed from the base, 

 with wide rounded sinuses between them, slender, acuminate, tipped with small red 

 glands, and glandular-serrate, with stipitate red glands; stamens 20; anthers pale 

 yellow; styles 4 or 5, usually 5. Fruit ripening at the end of September, on stout 

 erect villose pedicels, in few-fruited clusters, subglobose or often broader than high,
