lower surface ; tertiary nerves subparallel or branched, distinct below ; 
petiole 3-34 in. long, rather slender, setulose ; stipules foliaceous, broadly 
falcate, 7 lin. long, 4 lin. broad, glabrous on one side, setulose and with a 
strong nerve near the concave margin on the other side. Male racemes
