Leaves decussate, in four distinct rows, spreading, triquetrous-canaliculate, straight but apically somewhat recurved, mid-ribbed, linear or narrowly obovate, 3-8 mm long, 1-2 mm wide, glabrous or sparsely tomentose mainly marginally and apically, acute, with hooked apex. Capitula solitary, sessile, terminal. Involucre cyathiform, 3-7 mm wide. Involucral bracts 20-30, outer ovate, inner gradually longer and oblong, innermost narrowly oblong with a spreading apical limb, up to 6.5 mm long, up to 2 mm wide, obtuse. Receptacle flat-convex, paleate. Paleae canaliculate, linear or sometimes narrowly spatulate, 4.5-6 mm long, 0.4-1 mm wide, dorsally gland-dotted, acute. Ray-florets 6-14. Tube cylindrical, 1.8-2.7 mm long, glandular. Lamina elliptic, 3.5-5 mm long, 1.3-2 mm wide, 4-veined. Style 3.3-5.5 mm long; style-branches 1.5-2.5 mm long. Achenes flattened, narrowly oblong, 1.8-3 mm long, 0.5-0.8 mm wide, laterally ± densely pilose; pappus as in disc-florets. Disc-florets 20-65, perfect. Corolla 3-4.1 mm long, 0.6-1 mm wide. Tube cylindrical, ± glandular. Limb narrowly cyathiform; corolla lobes 0.5-0.8 mm long, often dorsally gland-dotted. Style 4-5.5 mm long; style-branches 0.7-1 mm long, apically penicillate and truncate; stylopodium distinct. Anthers 2-2.5 mm long; tails c. 1/3 of the length of the anther.
