''Eriocaulon decangulare'', commonly known as ten-angled pipewort, hat pin and bog button, is a monocotyledonous plant native to the eastern United States, Mexico and Nicaragua. The plant's distribution is quite irregular, with several disjunct populations and a discontinuous primary range. Most of its habitat in the United States runs along the Atlantic Coastal Plain, but some populations also occur in more mountainous regions. It is found in areas of relatively low elevation and the plant does not occur higher than 300 metres above sea level. This pipewort is found in peat and sand that is moist to wet and associated with savannahs, bogs, low pinelands, ditches and the banks of cypress domes. ==Distribution and habitat== ''Eriocaulon decangulare'' is found in the United States, Mexico and Nicaragua.〔 In the United States it is mainly confined to the Atlantic Coastal Plain, but several significant outlying populations also exist in more mountainous and inland regions.〔 It does appear to be absent from the intermediate Piedmont region, however. The northernmost populations are in coastal New Jersey and Delaware, stretching south to Florida. There is a significant break in the range along the coast in Georgia. The range then extends along the Gulf Coast though Alabama and Mississippi and just enters Louisiana. There is also a relatively large disjunct distribution in northern Alabama. The primary range breaks once more before starting again in central Louisiana, whence it extends into eastern Texas. Southern Arkansas supports another large disjunct distribution.
