Morphology General Habit
Procumbent or ascending much-branched annual or perennial, up to 1 m. tall.
Morphology Stem
Stem rather densely spreading pilose.
Morphology Leaves
Leaves 3-foliolate; leaflets variable, with the lower ones ovate-lanceolate to elliptic or obovate, up to 35–60 mm. long, 20–42 mm. wide, the upper ones narrower, narrowly oblong-lanceolate to ovate-lanceolate, glabrous above, thinly subappressed pilose beneath; petiole up to 25–50 mm. long.
