Leaves ovate or oblong, acuminate, short-pointed or sometimes rounded at the 

 apex, gradually narrowed below, entire, with undulate margins, and coarsely reticu- 

 late-venulose, when they unfold yellow-green and lustrous above, pubescent below, 

 and ciliate on the margins, and at maturity 4'-8' long, ^'-4' wide, thick and firm, 

 dark green on the upper, pale and glabrous on the lower surface except along the 

 stout midribs and conspicuous arcuate primary veins more or less covered with short 

 white hairs, turning bright clear yellow before falling early in the autumn ; their 

 petioles stout, puberulqus, ^'-1' long. Flowers slightly and agreeably fragrant, 

 appearing when the leaves are about one third grown, in loose pubescent drooping

 cence oblong, glabrous on the upper, pubescent on the lower surface, and sometimes 



1' long, those at the base of the upper branches oval, successively smaller, and grad- 

 ually passing into the minute laciniate bracts subtending the lateral pedicels of the 

 3-flowered clusters terminating the last divisions of the panicle; some individuals 

 bearing flowers functionally perfect, others flowers with sterile anthers and well- 

 developed stigmas, and others flowers with imperfectly developed stigmas and fertile 

 anthers; calyx light green, glabrous, with acute entire or laciniately cut lobes; corolla
