A plant of more or less robust habit and often much branched ; 

 in open fields either suberect and compact, or, generally later in 

 the year, more or less diffuse ; in bushy places and in shade often 

 rampant and climbing by its cirrhose petioles. Leaves 2-3 

 pinnatisect, usually somewhat glaucous, with leaflets cut, some- 

 time more or less divaricately, into flat, lanceolate or linear - oblong , 

 acute or slightly mucronate lobes. Bacemes dense at first, but 

 afterwards lengthening, many-flowered (flowers normally more 

 than 20, sometimes many more), exceeding the peduncles. Bracts 

 linear-lanceolate, acuminate, generally a little shorter than the 

 fruiting pedicels, but occasionally only half as long. Fruiting 

 pedicels of moderate thickness, straight and erect -spreading. Sepals 

 2-3| mm. long and 1-1-|- mm. broad, ovate or ovate-lanceolate, 

 scarcely peltate, irregularly dentate or laciniate towards the base, 

 acuminate or cuspidate, pinkish or less often white in colour, with 

 a fine purple or greenish median nerve, narrower than the corolla- 

 tube. Corolla 7-8 (rarely 9) 7nm. long, purplish-pinh in colour, 

 with the tip of the inner petals and the loings of the upper one 

 blackish-red. Upper petal broad and dorsally compressed, obtuse 

 or rarely apiculate, with a spathulate dilation of the erect-spreading 

 wings exceeding the keel and usually extending to its apex. 

 Lower petal tvith spreading margins narrow below but more or 

 less abruptly dilated towards the apex in a spathulate outline. 

 Fruits of moderate size, about 2 mm. long and 2|-3 mm. broad, 

 truncate or retuse and almost obre^iiform in profile (broadest above 

 the middle) with, occasionally, a small apiculus, little compressed 

 laterally and obscurely keeled, and narrowed below to an almost 

 obsolete neck nearly equalling the tip of the pedicel ; when dry, 

 rugose with rather broad and shallow apical pits.
