 obscurely ridged on the back, about ^ long and ^-^' wide. 



A tree, 20-25 high, with a trunk 6'-8' in diameter, branches spreading out into

Leaves oblong or obovate-cuneiform, rounded or acute at the apex, gradually 

 narrowed and wedge-shaped at the slender entire base, and sharply serrate above 

 the middle, with straight or incurved glandular teeth, when they unfold more or less 

 pubescent on the two surfaces, and at maturity subcoriaceous, dark green, lustrous 

 and glabrous or glabrate above, pale and covered below with short matted pale 

 hairs most abundant on the thin midribs and obscure primary veins, l^'-2' long, ^'-1' 

 wide, turning in the autumn orange, yellow, or brown; their petioles slender, nar- 

 rowly winged above, puberulous, about \' long. Flovrers opening at the end of April 

 when the leaves are fully grown, ^-f in diameter, on short villose pedicels, in com- 

 pact few-flowered villose corymbs; calyx narrowly obconic, coated with matted white 

 hairs, the lobes narrowed, acute, entire or sparingly serrate, glabrous on the outer, 

 slightly villose on the inner surface toward the apex; stamens 20; anthers yellow; 

 styles usually 2 or 3. Fruit ripening in October, oval or oblong, nearly ^' long, 

 yellow, the calyx prominent, with elongated mostly recurved lobes; flesh thin, dry 

 and mealy; nutlets usually 2, narrowed and acute at the ends, ridged on the back, 

 about 1' long.
