Every part of the plant thickly clothed with long 
spreading villous hairs. Stem frutescent, erect, not much 
branched: branches somewhat flexuose, rather succu¬

and the points and margins slightly reflexed, sharply 
toothed with unequal rigid horny teeth, underneath 
strongly nerved, the nerves branched all over the leaf. 
Petioles flattened on the upper side, and convex on the 
lower, a little thickened at the base. Stipules oblongly 
or ovately lanceolate, tapering to a long slender point. 
Peduncles cylindrical, mostly 4-flowered. Flowers very 
large, pale purple. Involucre of 6 bractes, more or less 
connected: bractes ovate or oblong, with a short sharp
