An essentially slender and usually small plant, sometimes 

 suberect, compact and much branched in open fields, more often 

 diffuse or climbing by its cirrhose petioles. Leaves irregularly 

 2-3 pinnatisect, sometimes more or less glaucous, with leaflets 

 (which are frequently very small) cut into oblong or lanceolate, 

 mucronate or acute lobes. Bacemes rather lax and feio (usually 

 sub-12) floiuered, about equalling the straight or incurved peditn- 

 cles. Bracts linear-lanceolate, acuminate, usually two-thirds as 

 long as the slender fruiting pedicels, which are normally straight 

 and erect-spreading or sub-patent but occasionally flexuous and 

 somewhat recurved. Sepals 3-4 mm. long and 1^-2 mm. broad, 

 ovate, peltate, often much toothed, especially towards the base and 

 along the lower margin, and generally acuminate ; whitish in 

 colour or suffused with pink, with a greenish median line ; as 

 broad as the corolla tube. Corolla 9-11 mm. long, but rarely 

 exceeding 10 mm., pink in colour, with the tip of the inner petals 

 and the loings of the upper one blackish red. Upper petal some-
