FRUIT. Oblong-obovate to elliptic; % inch long; wing shorter 

 than and extending to below middle of terete seed cavity. 



TWIGS. Rounded; slender; velvety pubescent first year. 



BARK. Thin; furrowed; gray, slightly tinged with red.

GENERAL. F. velutina passes into the following varieties: 

 1. coriacea Rehd., with leathery leaves. 2. glabra Rehd., with 

 glabrous leaves and branches. 3. toumeyi Rehd., with lanceolate,
