A decumbent or prostrate ‘annual, with stems 6-12 inches long or longer, villous 
or glabrescent, in 8. hispid or hirsute. Leaves opposite, unedual, the longest 1-11 
inch ; leaflets oblong, acute, green above, sparingly appressedly villous, below ap- 
pressedly pubescent, often whitish or silky. Stipules ovato-lanceolate, 2-3 lines 
long. Peduncles axillary, solitary, shorter than the leaf, the fruit- stalk nearly as 
long, villous or, in 8., hairy. Flowers yellow or whitish. Sepals 14-2 lines long. 
Petals } as long again as the calyx, obtuse. Stigma roundish-conical, 5-rayed, with 
inconspicuous style. Carpels crested and tubercled on the back, or prickly and

upper spines much divaricate, 3 lines long ; 2 lower turned downwards and shorter. 
In var. y. the upper spines are not more than I line long, often much shorter, some- 
times very short and confounded with the dorsal prickles. Var. B. is not unlike 7’,

long styles. é
