to 16 in the upper pinnae, 6 to 10 in the lower ones, decreasing in size down-

Flowers small, perfect, 5-merous, in globose heads which are solitary, fas- 
cicled, or paniculate. Calyx campanulate or funnel-shaped, shortly toothed. 
Corolla narrowly funnel-shaped, the petals united below the middle. 
Stamens exserted, monadelphous; anthers not gland-crested. Ovary many- 
ovuled; style filiform; stigma capitate. Pod strap-shaped, variously 
faleate, or circinate, usually much twisted at maturity, dehiscent. Seeds 
arillate or not. (Greek “monkey” and “pod.’’)
