TheEriocaulaceae are afamily ofmonocotyledonousflowering plants in the orderPoales, commonly known as thepipewort 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 intropical regions, particularly theAmericas. Very few species extend totemperate regions, with only 16 species in theUnited States, mostly in the southern states fromCalifornia toFlorida, only two species inCanada, and only one species (Eriocaulon aquaticum) inEurope. 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 mostlyherbaceousperennial plants, though some areannual plants; they resemble plants in the related familiesCyperaceae (sedges) andJuncaceae (rushes), and like them, have rather small, wind-pollinatedflowers grouped together incapitulum-likeinflorescences.
