 short, about as long as, or longer than the leaf, 1-3-flowered ; pedicels 

 very short ; bracts linear, resembling the leaf-segments. Calyx covered 

 with the characteristic hairs, about 2 lin. long; sepals subcoriaceous, 

 elliptic, with the apex drawn out into a long point, the two inner much 

 smaller. Corolla naiTowly funnel-shaped, yellow, scarcely exceeding 

 the calyx. Anthers ultimately slightly twisted. Ovary densely hairy, 

 1-celled, 2 ovules in each cell. Capsule small, globose, hairy, 3 lin. in 

 diam. Seeds glabrous. — Hallier f. in Engl. Jahrb. xxx. 386 ; Dammer in
