Flowers in large erect terminal panicles exfending into tlie axils of tlie 

 upper leaves, 8-16 in. long, 6-8 in. across, composed of alternate crowded 

 corymbs 3-4 in. long, 2 in. across; lower pedicels 1 in. long solitaiy in 

 axils of small lanceolate bracts 2 in. long, grey-pubescent as are the 

 branches and main rachis. Calyx 6-partite to base, segments distinctly 

 unequal, ovate-obtuse, greenish-yellow, downy externally, the larger '35 

 in. the smaller '2 in. long. Petals 5 suborbicular, '75 in. long, '6 in. 

 wide, except the upper obcordate '6 in. long, 5 in. wide, all rather 

 pale nniform-yellovv. Stamens 7 (the 3 upper reduced to staminodes) 

 the 3 lower with much larger anthers and longer filaments than the 

 2 lateral pairs. Pod nearly straight, flat, thin, sliglitly swollen opposite 

 the seeds, sutures faintly thickened, valves thickly coriaceons, sparsely 

 puberulous, 6-9 in. long, '5 in. wide, with a distinct stalk '5 in. long. 

 Seeds biseriate 20-30, oval, '3 in. long, '25 in. across, very thin, testa
