Heads 25-30-flowered, solitary, terminal, broadly eampanulate, 1.5-2 cm long, nearly 2 cm in diameter. Involucral bracts 3-4-seriate; the outermost resembling the leaves and scaly outside, oblong-lanceolate, rounded at the apex, about 7 mm long, with very broad membranous margins, gradually increasing in length upwards; the innermost about 1.5 cm long and more or less of the same shape as the outer; all glabrous. Receptacle small and convex. Corolla-tube gradually widened upwards, 8 mm long, glabrous; lobes lanceolate, subacute, 2.5-3 mm long. Anthers slightly exserted.
