Description
Species Description - Glabrous, slightly punctate perennial herb or with new growth from old stems, said to be malodorous. Stems usually clustered and branched, mildly stipitate-glandular, from a rhizomatous or heavily woody base, 2-5 dm. Lowermost leaves 1-pinnate with ca 4 pairs leaflets, remainder 2-pinnate (to 15 cm including terminal pinnae); leafstalk 2-8 cm, often flexuous; pinnae (1-)2-5 pairs plus 1, the terminal considerably the longest; leaflets 4-6 pairs on lateral pinnae, 9-12 pairs on terminal pinna, subpetiolulate, asymmetrically ovate, basally rounded, truncate to subcordate, 2-9 mm, .9-1.6 r, diminishing in size distally, glabrous to glaucous and blue-green, sparsely and inconspicuously punctate, evidently nerved, apically mucronulate. Stipules irregularly deltoid to broadly ovate, acute, membranous. Flowers 5-15 in exserted racemes, divergent or nodding. Pedicels initially ascending, then divergent, to 1 cm, not jointed, evidently stalked-glandular; calyx lobes 7-10 mm, slightly imbricate and unequal, pubescent, reflexed, deciduous after anthesis; petals yellow, red-streaked, 9-12 mm, obovate, short-clawed, conspicuously punctate; filaments approximating or exceeding petals, pubescent below. Legume elastically dehiscent, half-ovate or lunate to asymmetrically oblong, flat, 2-5 cm long, 10-17 mm broad; valves moderately punctate and stipitate-glandular. Seeds 2-4.
