 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-subulate brac- 

 teoles, above 6 lin. long, 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 ( Welivitsch) ; midpetaline areas trinerved and 

 bearing in the upper portion a few of the characteristic hairs. Capsule 

 dehisced, apparently subspherical, about 3 lin. in diam., valves rather 

 thin, 2-celled, 2-seeded. Seeds blackish, minutely pubescent. — Hiern in
