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]

Habitat

Typically found in a lake with a depth of 0 to -1,142 meters (0 to -3,747 feet).[3]

Ecology: Eriocaulon truncatum is an annual herb grows in marshy places (Yadav and Sardesai 2002), inundated places, wet rocks, common in rice fields (Cook 1996), river banks, drains (Khanna et al. 2001) and also near ponds (Laksminarasimhan 1996).[4].
