Abstract

Dwarf caespitose perennial herb; rhizome short; roots dense, thin and long, fibriform; leaves acerose, dorsiventral, ventrally subsemiorbicular and 2-canaliculate, dorsally flattened and 1-canaliculate, sheathed at the base. Inflorescence a compound capitulum on a scape arising from the rhizome, at the base usually surrounded by 3 leaflike aristate bracts, the peduncle bearing 5–8 few-flowered capitula, the flowers subtended by aristate bractlets. Flowers hermaphroditic, actinomorphic, epigynous, shortly pedicellate; perianth corollinic, pink, tubular; perianth lobes 3 + 3, the inner lobes slightly smaller than the outer; stamens 3 + 3, borne upon the corolla lobes; filaments short; anthers oblong, bisporangiate, dorsifixed, introrse, dehiscing by longitudinal slits; ovary inferior, syncarpous, in lower part trilocular with axile placentation, in upper part unilocular with parietal placentation; ovules numerous, anatropous, bitegmic; style elongate, with trilobate stigma; fruit capsular, trigonous, shortly rostrate; seeds oblong, brown; endosperm starch-containing; embryo large, central.
