Leaves decussate, in four indistinct rows or sometimes alternate, spreading, triquetrous, mid-ribbed, obovate-oblong, 2-7 mm long, 1-1.5 mm wide, glabrous or sparsely tomentose mainly marginally and apically, acute, with somewhat hooked apex. Capitula solitary or paired, almost sessile, terminal. Involucre narrowly cyathiform, 3-4 mm wide. Involucral bracts 25-30, outer ovate, inner gradually longer and oblong, innermost obovate with a spreading apical limb, up to 6 mm long, up to 1.8 mm wide, innermost dorsally sparsely gland-dotted, obtuse. Receptacle convex-conical, epaleate. Ray-florets 5-7. Tube cylindrical, 1.5-2 mm long, glandular. Lamina elliptic, 3-4 mm long, c. 1 mm wide, 4-veined. Style 3.5-4 mm long; style-branches 1-1.5 mm long. Achenes as in disc-florets, but more densely glandular. Disc-florets c. 18, perfect. Corolla 3.5-4.3 mm long, 0.7-0.9 mm wide. Tube cylindrical, glandular. Limb cyathiform; corolla lobes 0.6-0.8 mm long, dorsally gland-dotted. Style 4-4.5 mm long; style-branches 0.6-0.8 mm long, apically penicillate and truncate; stylopodium distinct. Anthers 2.1-2.4 mm long; tails c. 1/3 of the length of the anther.
