dark green, smooth and lustrous, 4'-5' long and l|'-2' wide, persistent; their petioles 

 stout, wing-margined toward the apex, channeled, about ^' long. Flo"wers about 

 2^ in diameter, expanding in July and continuing to open successively during 

 several weeks, on stout red peduncles thickening from below upward, and 2^'-3' 

 long, with usually 3 or 4 ovate minute subfloral bracts; sepals ovate to oval, \' long, 

 ciliate on the margins, with long white hairs, and covered on the outer surface with 

 dense velvety pale lustrous pubescence; petals rounded at the apex, gradually con- 

 tracted at the base, silky-puberulent on the back, white, 1|'-1^' long and V broad; 

 stamens united into a shallow fleshy deeply o-lobed cup pubescent on the inner surface 

 and adnate to the base of the petals; ovary ovate, pubescent, gradually contracted 

 into the stout style. Fruit ovoid; seeds winged, nearly square, slightly concave 

 on the inner and rounded on the outer surface, rugose, dotted with small pale brown 

 excrescences, nearly ^^' long and half the length of the thin membranaqeous oblique 

 pale brown wing pointed or rounded at the apex; embryo filling the cavity of the 

 seed, nearly straight; cotyledons subcordate, foliaceous. 



A short-lived tree, 60-75 high, with a tall straight trunk 18-20' in diameter, 

 small branches growing upward at first and ultimately spreading into a rather nar- 

 row compact head, and dark brown rugose branchlets marked during several years 

 by the horizontal slightly obcordate leaf-scars; or rarely alow shrub. "Winter-buds 

 \'-\' long, and covered with pale silky lustrous pubescence. Bark of the trunk 

 nearly V thick, deeply divided into regular parallel rounded ridges, their dark 

 red-brown scaly surface broken into many irregular shallow furrows. Wood light,
