Description

provided by Flora of Zimbabwe
Annual or perennial herbs, usually with short stems. Leaves narrow, spirally arranged in a crowded basal rosette (rarely (setaceum) borne on elongated stems). Inflorescence capitate, white, dirty grey, brown or black. Capitula of many small unisexual flowers on a central receptacle, surrounded by 1-several whorls of involucral bracts; each flower often subtended by a floral bract. Flowers (2-)3-merous, ± actinomorphic to strongly zygomorphic. Perianth usually composed of 2 distinct whorls; calyx of free to almost connate sepals, sometimes spathe-like especially in male flowers. Petals free or partly connate, often with a subapical black gland. Male flowers: stamens as many as or twice the number of sepals. Female flowers: ovary 2-3-locular, superior; style branched. Fruit a loculicidally dehiscent capsule; each loculus 1-seeded.

Eriocaulaceae

provided by wikipedia EN

The Eriocaulaceae are a family of monocotyledonous flowering plants in the order Poales, commonly known as the pipewort family. The family is large, with about 1207 known species described in seven genera.[3] They are widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly the Americas. Very few species extend to temperate regions, with only 16 species in the United States, mostly in the southern states from California to Florida, only two species in Canada, and only one species (Eriocaulon aquaticum) in Europe. They tend to be associated with wet soils, many growing in shallow water. This is also reported from the southern part of India and the regions of Western Ghats hot spots.

The species are mostly herbaceous perennial plants, though some are annual plants; they resemble plants in the related families Cyperaceae (sedges) and Juncaceae (rushes), and like them, have rather small, wind-pollinated flowers grouped together in capitulum-like inflorescences.
