Family Eriocaulaceae

Herbs perennial or annual . Leaves in a rosette, grasslike, linear , occasionally thinly filiform , often thin and transparent, fenestrate, base sheathing . Inflorescences capitate, globose to ovoid ; scapes thin, twisted, angled , base surrounded by a bladeless, tubular sheath . Flowers 2- or 3-merous, bracteate , with both sexes usually in same head . Male flowers: sepals 2 or 3, connate or free ; petals 2 or 3, often inconspicuous; stamens 6. Female flowers: sepals 2 or 3, free or connate; petals absent to 4, free; ovary (1--) 3-loculed; ovules 1 per locule, basal; style 1, 1--3-branched. Fruit a capsule, thin, loculicidal. Seeds small; testa usually reticulate and prickly; endosperm with abundant starch grains.

Ten genera and ca. 1150 species: mainly in tropical and subtropical regions; one genus and 35 species (13 endemic) in China.[1]

Genus Eriocaulon

Herbs, annual or perennial , often cespitose, rosulate. Roots : larger roots unbranched, pale , septate , thickened, spongy . Stems rarely sparingly branched, short or elongate . Leaves many ranked in flat or high spiral ; blade basally pale, distally greener, linear-attenuate or triangular-acuminate, lingulate , narrowing gradually or abruptly from base , base noticeably lacunate , less distinctly so distally. Inflorescences: scape sheaths tubular , orifice oblique (often 2--3-cleft) ; scapes 1--several per rosette, glabrous ; heads pale to dark, white, gray, or gray-brown, hemispheric to globose or short-cylindric; receptacle hairy or glabrous; involucral bracts obscured or not obscured by inflorescence, pale to dark, chaffy or scarious ; receptacular bracts narrower, thinner than involucral bracts, often scarious. Flowers mostly with staminate and pistillate on same plants , 2--3-merous; sepals 2(--3), adnate to stipelike base, boat-shaped , scarious, apex often covered with multicellular hairs , hairs mealy white or translucent , frequently club-shaped; petals 2(--3), narrower, shorter than sepals, apex hairy, hairs club-shaped, glands adaxial , subapical , dark, rarely pale. Staminate flowers : androphore apically dilated stalk ; petals separated from sepals by androphore, diverging as lobes from apex; stamens 3--4 or 6, 2--3 alternating with petals; apex of staminal column with 2--3 glands, glands unappendaged; filaments arising from androphore rim; anthers 2-locular, 4-sporangiate, dorsifixed , usually versatile, well exserted at anthesis , jet black (except in E. cinereum) . Pistillate flowers: gynophore separating petals from sepals, stipelike; pistil 2(--3) -carpellate; style 1, unappendaged, style branches 2(--3) .

Species ca. 400: mostly pantropic, mostly aquatic or on wet, mainly acidic substrates.[2]
