much-branched perennial, with a thick fusiform woody root. Stem 
branched from the base; branches (4-6 in. long) and_ branchlets 
subspreading, generally thin, densely leaved and clothed like the leaves 
with dense long spreading yellowish hairs. ‘Leaves nearly sessile, oval, 
becoming more or less oblanceolate to obovate, shortly acute to obtuse, 
base obtuse to subacute; blade rarely exceeding 1 in. in length often 
less. Flowers solitary on short pedicels (4 lin. long or less) from the 
axils of the upper leaves with a pair of long linear-subuiate brac- 
teoles, above 6 lin. Jong, below the flower. Sepals linear-lanceolate 
below with a long linear-subulate upper portion, nearly 8 lin. long, 
densely ciliate like the young shoots. Corolla probably 1 in. long 
when spread, infundibuliform-campanulate, pale rose outside, in- 
tensely blood-red inside (Welwitsch); midpetaline areas trinerved and 
bearing in the upper portion a few of the characteristic hairs. Capsule
