Name: Pinus palustris / Eryngium integrifolium - Rhynchospora spp. - (Ctenium aromaticum) Woodland Reference: NatureServe Biotics 2019 Description: This is a saturated longleaf pine woodland community of central to west-central Louisiana, presumably ranging into adjacent or related areas of Texas. The <i>Pinus palustris</i> canopy in frequently burned, relict stands is typically open. Shrubs are absent to patchy. The herbaceous layer in this woodland is well-developed and very species-rich. Dominants include <i>Ctenium aromaticum</i> (within its range, east of the Sabine River), <i>Muhlenbergia expansa, Rhynchospora plumosa, Rhynchospora globularis, Rhynchospora glomerata, Rhynchospora</i> spp., <i>Panicum virgatum, Eriocaulon decangulare, Eryngium integrifolium, Rhexia lutea</i>, and <i>Eupatorium</i> spp. Residual stands of this community are known from intermediate and high Pleistocene terraces. Soils are poorly drained to very poorly drained, acidic, silt loams and also perhaps fine sandy loams. Average fire-return time historically was believed to be 1-3 years, few remaining examples are subject to such frequencies. This community is geographically isolated from the larger belt of <i>Pinus palustris</i> flatwoods that occurs in southwestern Louisiana and southeastern Texas. For now, this community includes poorly studied variants which occur on the Fleming Formation in central Louisiana and Texas ('Westcentral Tertiary Flatwoods Variant' of Smith 1995a); further study of these may reveal that they warrant recognition.  Accession Code: urn:lsid:vegbank.org:commConcept:32518-{6F6712AF-3D60-4096-B57A-7E57E573C61B} Plot-observations of this Community Concept: 0
