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 1,150-1,200 species described in 10 genera. 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. ;Genera *''Actinocephalus'' *''Comanthera'' *''Eriocaulon'' - pipewort *''Lachnocaulon'' - bogbutton *''Leiothrix'' *''Mesanthemum'' *''Paepalanthus'' *''Philodice'' *''Rondonanthus'' *''Syngonanthus'' *''Tonina'' ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eriocaulaceae」の詳細全文を読む スポンサード リンク
