point, the outermost pair much smaller than the other three. Flowers 
very numerous, in moderately dense short-peduncled terminal racemes 
reaching 5—6 in. long, 15-18 lines broad. Bracts minute, setaceous. 
Pedicels 1}—2 lines, finely grey-silky. Calyx 2}—8 lines, the lanceo- 
late-deltoid teeth shorter than the tube. Corolla bright uniform 
yellow, more than twice the calyx. Pod distinctly-stalked, linear,

leaves inhabit the shores of the Mediterranean, of which one extends into Tropical 
Africa.
