but not similarly brown on both sides, quite variable in 
size, the larger blades 8 cm. long by 3.5 em. wide across 
the middle, elliptic or oblongish so, entire and subinvolute 
in the dry state at least; midrib conspicuous beneath, usually 
with only 2 pairs of lateral nerves arising from near the

chiefly terminal or from the uppermost leaf axils, 8 to 5 cm. 
long, suberect; rachis green, angular when dry, subtended 
at the base by short and broad imbricated bracts, in the 
flowering state finely puberulent; pedicels scattered divari- 
cately all along, strict, also puberulent, 5 mm. long, stout, 
subtended by vestiges of bracts, articulate or jointed at the 
base; calyx also articulate, short turbinate, 9 mm. high,

corolla crimson red, tapering from the more or less inflated 
base to the minutely 5-toothed apex, 7 mm. long, 3.5 mm. 
wide at the base, glabrous; stamens 10, inserted upon the corol-
