 foot high, glabrescent, or pubescent in the upper younger portion. 

 Leaves membranous, subsessile or shortly stalked, obliquely elliptic, 

 apex abruptly acuminate, base unequal, on the broader side

 more or less pubescent on the prominent nerves, rarely glabrous; 

 petiole up to 3 lin. long. Stipules lanceolate-acuminate to subulate,
