Pelargonium rutaceum. Swt. hort. Irit. p. 84. n. 389. 
Root large, branching out into numerous tubers, of 
various shapes and sizes. Stem fruticose, succulent, 
knotted unequally in irregular large swellings at the joints, 
of a brownish glaucous colour, the upper part thickly 
clothed with long spreading white hairs, and producing a 
few long slenderish flowering branches. Leaves like a 
large fern or umbelliferous plant, the upper ones like Rue, 
to which the scent also bears a strong resemblance, suc- 
culent, glaucous : lower ones very large and spreading, 
decompoundly divided ; others pinnate, the leaflets pinna- 
tifid or bipinnatifid ; segments oblong, or sometimes lan- 
ceolate, acute, incised or sharply toothed, or sometimes 
entire. Petioles nearly cylindrical, swollen at the base, 
thinly clothed with long spreading hairs, very slender when 
compared with the large leaf, which it can scarcely support 
without assistance. Stipules variable, some broadly cor- 
date, and others lanceolate, acute, slightly hairy and 
fringed. Peduncles very long, slightly angular, glaucous, 
also hairy. Involucre of numerous lanceolate, acute, 
fringed bractes, their points terminated by a little tuft of 
bristly hairs. Pedicles very short, not half the length of 
the bractes. Calyx 5-cleft; segments ovate, bluntish, . 
pubescent, all tipped with a tuft of long white hairs. Nec- 
tariferous tube pubescent, a little flattened on each side,
