An erect shrub with 3-foliolate leaves on slender gray silky branchlets; leaflets 

 oblong-lanceolate, entire, subcoriaceous, thinly silky above, densely so beneath; stip- 

 ules minute, lanceolate; flowers yellow, or the standard veined with red, growing in 

 sparsely flowered racemes, often forming a terminal panicle; pod 5 to 7.5 cm. long, 

 finely downy, tipped with the lower half of the style. 



This plant grows spontaneously in the Sudan, and is cultivated in India, Mada- 

 gascar, New South Wales, Jamaica, Malabar, Brazil, and other warm countries. 

 The seeds are nutritious and are eaten either green or dry, like peas. The plant will 

 live several years, and in good soil begins bearing the first year. It was introduced 

 into Guam in 1772 by the French ship Castries, whence its local name, which signi- 

 fies " French lentil." It is planted at the beginning of the rainy season.
