Perennial. Rootstock probably a tuber. Stem dividing at ground-level into 2–3 erect or ascending branches 1/2–8 in. long, puberulous. Leaves alternate or at the inflorescence opposite or subopposite, of rather thick texture, 1/4–2 1/4 in. long, 2/3–2 1/2 lin. broad, linear or linear-lanceolate, acute, very shortly narrowed to a subsessile base or into a short petiole, glabrous on both sides or sometimes with a few minute curved hairs on the keel-like midrib beneath, sometimes minutely ciliate when young. Stipules minute and gland-like, or none. Peduncles solitary, arising in the forkings of the stem or falsely axillary, 1/4–1 in. long, erect, puberulous. Involucre 2–2 1/2 lin. long and 3–3 1/2 lin. in diam., broadly cup-shaped with 5 glands and 5 lobes, puberulous or tomentose, with minute curved hairs outside; glands 2/3– 3/4 lin. long and 3/4–1 1/4 lin. broad, peltate, 2-lipped, lips somewhat pressed together, forming an oblique flattened funnel-shaped cavity, with the lip on the inner side half as long as the outer, both broadly rounded, entire; lobes transversely oblong, 1 1/4–1 1/3 lin. broad, truncate and cut into a fringe of many ciliate teeth at the top. Ovary densely tomentose when young; styles short and thick, bifid at the recurved tips. Capsule not seen.
