A native of Cape Colony. 
Lower part of the stem woody to the height of sometimes a 
foot, the upper part herbaceous, firm, erect, copiously branched 
and striated, densely clothed throughout with conspicuous 
spreading gray hairs. Stipules membranous, broad deltoid, 
three or four lines long, cuspidate. Peézoles firm, erecto-patent, 
pubescent, of the upper leaves an inch, of the lower reaching 
three or four inches long. Leaves deltoid in general outline, 
when well-developed three to five inches long and broad, deeply 
cordate at the base, with numerous palmate lobes reaching about 
half down to the midrib, which are again pinnatifid, and the edge 
all round finely serrato-denticulate, the texture quite herbaceous, 
the upper surface full green, the lower paler, both soft with 
copious shining gray hairs, the numerous veins conspicuous on 
both sides, being channelled above and raised beneath. A well- 
developed stem, copiously dichotomously branched at the top, 
and producing twenty to thirty wmbels of three to eight flowers 
each, on erecto-patent downy peduncles, one to two inches long. 
Pedicels at the flowering time three or four lines long, hispid; 
the lanceolate-acuminate membranous bracts rather shorter; the 
calyx-tube two lines deep ; the oblong-lanceolate sepals three and
