Flora of Virginia Name/Status
Eleocharis wolfii (Gray) Gray ex Britt. in H.N. Patterson
A Midwestern species resembling Eleocharis compressa in its compressed culms, but usually gray-green in color. It also has distinctive hyaline leaf sheaths and achenes with several distinct longitudinal ribs. Due to its immature condition, a 1995 collection from the Banister River went undetected until 2006; since then, additional stations have been found in this drainage. In 2019, Nelson Debarros discovered that Fairfax County populations previously misidentified as Eleocharis compressa were in fact E. wolfii. The Virginia populations, and one from Cabarrus Co., NC, are significantly disjunct from the species' main range and represent the only records from the Mid-Atlantic region.
Poorly drained oak flatwoods dominated by Quercus phellos, Q. palustris, and Q. bicolor, in a Triassic Basin floodplain of the southern Piedmont; upland depression swamps of the northern Piedmont Culpeper Basin with similar clay, hardpan soils. Rare, Piedmont, known only from Pittsylvania and Fairfax counties.
