Name: Juncus militaris - Eriocaulon aquaticum Marsh
Reference: NatureServe Biotics 2019
Description: This Coastal Plain pondshore vegetation of southern New England and possibly Ontario occurs in shallow standing water at the shore of permanent water bodies. The sandy or gravelly substrate generally supports an organic layer of variable depth. <i>Juncus militaris</i> dominates the association. Regular associates include <i>Gratiola aurea, Nymphoides cordata, Nymphaea odorata</i>, and <i>Eriocaulon aquaticum</i>. Other species occurring in this type include <i>Pontederia cordata, Hydrocotyle umbellata, Eleocharis robbinsii, Eleocharis olivacea, Sagittaria teres, Lysimachia terrestris, Sium suave</i>, and <i>Triadenum virginicum</i>. This vegetation is similar to ~<i>Eriocaulon aquaticum - Lobelia dortmanna</i> Marsh (CEGL006346)$$ in its similar topographic position and apparently similar hydroperiod, and in the presence of <i>Eriocaulon aquaticum, Gratiola aurea</i>, and <i>Nymphoides cordata</i>. It differs in its physiognomy, being dominated by a tall, coarse rhizomatous graminoid, and although environmental measures are lacking, organic layer depth is suspected to be deeper in this type because of the presence of such plants as <i>Pontederia cordata, Eleocharis olivacea</i>, and <i>Triadenum virginicum</i>.
