incurved teeth, when they unfold tinged with red and sparingly villose above and on the 

 midrib below, soon glabrous, nearly fully grown when the flowers open at the end of April, 

 becoming at maturity thick and firm or subcoriaceous, bright green and lustrous on the 

 upper surface, pale on the lower surface, \\'-9L\' long, and I'-l-J-' wide, with a stout yellow 

 midrib and primary veins; turning in the autumn yellow, orange, and brown; petioles stout, 

 reddish brown toward the base, about 1' in length; leaves at the end of vigorous shoots 

 broadly oval, coarsely serrate, mostly slightly incisely lobed, 3'-4' long, and l'-2' wide, 

 with a thicker midrib and veins. Flowers \' in diameter, on long slender pedicels, in broad 

 many-flowered corymbs; calyx-tube narrowly obconic, the lobes linear-lanceolate, entire or 

 remotely serrate; stamens 10 ; anthers yellow; styles 2 or 3. Fruit ripening in September or 

 October, on slender stems, in few-fruited drooping clusters, short-oblong, \'-\' long, green 

 tinged with red; calyx-lobes slightly enlarged, reflexed and often deciduous from the ripe 

 fruit; flesh yellow, dry and mealy; nutlets 2 or 3, about |' long. 



A tree, often 20 high, with a tall trunk 8'-12' in diameter, stout ascending or spreading
