 sometimes caudately sometimes abruptly, cuneate at the base ; glabrous 

 above except on the midrib, covered beneath with a silky golden-brown 

 pubescence, afterwards glabrate ; 6 to 9 in. long, 2 to 3 in. broad ; mid- 

 rib prominent, minutely pubescent above or glabrous ; main-nerves 20 

 to 25 pairs, "3 to -5 in. apart, starting at an angle of about 70° with the 

 midrib, at first parallel, ultimately ending in a looped intramarginal 

 nerve ; secondary nerves between the main-nerves, obscure like the 

 reticulations ; petiole 1 in. long, bordered above by the decurrent 

 margins of the blade ; stipules linear, subulate, -3 in. long, golden- 

 pubescent, quickly caducous. Flowers fascicled, 2 to 6 together in
