, occasionally thinly filiform
, often thin and transparent, fenestrate, base
sheathing
. Inflorescences capitate, globose

and subtropical
regions; one genus and 35 species (13 endemic) in China.[1]

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

). Leaves linear-attenuate,
1--10 cm (--20 cm when submersed), apex filiform
. Inflorescences:
scape sheaths
mostly shorter than leaves in emergents, exceeding
them in drier sites; scapes linear
, 1 mm wide, 4--7-ribbed; heads
(young or mature
) very pale
, hemispheric
to nearly globose
, rarely
short-cylindric, 4--10 mm wide, soft, flattened when pressed; receptacle
glabrous
; involucral bracts
sometimes squarrose, obscured by reflexed
bracteoles and flowers of mature heads, straw-colored, orbiculate
to ovate
, 2--2.5 mm, margins
entire, apex rounded
, with white, club-shaped
hairs
; receptacular
bracts and bracteoles pale except for grayish
midzone, obovate
to cuneate, 2 mm, margins entire, apex acute, ciliate
,
distal abaxial
surfaces with white, club-shaped hairs. Staminate
flowers: sepals 2, grayish, oblong-linear, curvate
, 1.5--2 mm, apex
acute with white, club-shaped hairs; androphore
club-shaped; petals
2, pale, triangular, 0.5 mm, ciliate, hairs club-shaped; stamens
4; anthers
black. Pistillate
flowers: sepals 2, basally pale, darkening
distally to grayish, gray-green, or gray-brown, narrowly oblong-obovate,
curved
, 2 mm, apex rounded, abaxially with white, club-shaped hairs;
petals 2, yellow-white, broadly spatulate
, flat, 1.5--2 mm, apex
rounded, abaxially with white hairs, adaxially with white or clear
hairs; pistil 2-carpellate. Seeds dark red-brown, ovoid
or ellipsoid
,
0.5--0.75 mm, faintly rectangular-reticulate, often papillate
in
lines
. [source]
Eriocaulon lineare closely resembles E. texanum, although it has
paler bracts and flowers and a glabrous (rather than pilose
) receptacle.
Eriocaulon lineare blooms
later and is most common in the margins
or shallows of ponds
, rather than in the sphagnous
bogs
favored by
E. texanum. [source]
Habit: Forb/herb
Flowers: Bloom Period: May, June, July, August, September, October.
Habitat
Sandy or peaty shores , hypericum ponds , wet savanna , southern coastal plain terraces ; 0--100 m [3].
Typically found in the intertidal zone at the water's edge at a mean distance from sea level of 46 meters (150 feet).[4]
Biome: Coastal.
