nating the furrow of the leafstalk just above its swollen 
base. Racemes few-flowered, corymbose, axillary, much 
shorter than the leaves. _ Flowers deep yellow, showy. Pe- 
tals nearly equal, spreading. Stamens 10, of which eight 
are fertile, declinate, and by degrees smaller upwards; two 
sterile, very small.
