Root tuberous, succulent, clothed with a dry rigid shell. 
Leaves radical, crowning the root, hairy all over, and 
bearded at the points, generally entire, but sometimes one 
or two of them a little divided near the base: lower ones 
ovate and bluntish, the others erect or slightly spreading, 
lanceolate, tapering to both ends, acute. Petioles rather 
long, clothed with a dense tomentum, and long hairs in¬ 
termixed. Scapes leafy, branching, producing many um¬ 
bels of flowers. Peduncles cylindrical, also densely to- 
mentose and hairy. Umbels generally about 6-flowered. 
Involucre of several linear, taper-pointed, fringed, woolly 
bractes. Calyx densely tomentose, hairy, and bearded with 
tufts of long hairs at the points: segments 5, lanceolate, 
acute. Nectariferous tube sessile, densely tomentose, a 
little longer than the calyx. Petals 5, white, stained with 
blush, and marked with light red veins; the two upper 
ones largest, spatulate, reflexed from about the middle, 
marked at the base with a dark purple patch, which bran¬ 
ches into lines over the petals: lower ones narrower, spread¬ 
ing, and not marked at the base. Filaments 10, short, con¬ 
nected at the base, 5 only bearing anthers, two of the fila¬
