nodes 5-10 cm. long; leaves alternate, but forked from the very 
base and thus appearing opposite, each fork pinnately decom- 
pound with filiform segments, 10-20 cm. long, one fork usually 
much more copiously bladder-bearing than the other; mature 
bladders I-1.5 mm. in diameter; scapes solitary, borne at alter-

nate, about 2 mm. long, slightly accrescent and spreading under 
the mature fruit; corolla yellow, the upper lip subtriangular, 
emarginate, about 3 mm. long and broad, the lower lip rounded, 
truncate or slightly emarginate, broader than long, 5-7 mm. long, 
10-12 mm. broad, the palate prominent, faintly 2-lobed, the spur 
conic-subulate, porrect, slightly shorter than the lower lip; ovules
