rounded at the other end and with a short mucronate 
point, beneath punctately glandular; midrib raised beneath, 
impressed above, usually with 3 lateral pairs; the basal pair 
arising a few mm. above the base and extending one half 
way of the blade, the middle pair more conspicuous and 
arched clear around to the apex, the upper pair obscure 
or obsolete; petiole glabrous or sparsely hairy, stout, not 
exceeding 5 mm. in length. Flowers in small axillary fas- 
cicles, subpendulous; pedicels 5 mm. long, subrecurved, pro- 
vided with few crisp hairs, subtended at the base by short 
rather thick imbricate bracts; calyx green, subtended at the

3 mm. wide, 5 mm. long, glabrate except the glandular 
margins of the triangularly shaped 5 teeth; corolla green- 
ish yellow, short cylindric, 5 mm. long, nearly as wide, the 5 
small recurved segments forming a truncate apex, glabrous;
