	abstract = {Isoetes microvela, sp. nov., is described from cytologically confirmed hexaploid populations from the coastal plain of North Carolina. At least one population grows over thinly-buried calcareous bedrock, a rare condition on the predominantly acidic southeastern coastal plain. It is a large quillwort of periodically inundated and scoured stream banks and shallow water. It is characterized by a densely short-crested to reticulate-tuberculate megaspore ornamentation pattern intermediate in appearance between that of I. appalachiana and I. hyemalis, an exceptionally small velum covering {\textpm} 10\% of the heavily brown-streaked sporangium, and by obscurely tuberculate microspores. A key to the Isoetes of the southeastern coastal plain is presented. Isoetes microvela is suspected to represent an allopolyploid derived from the doubling of a sterile triploid hybrid, most likely I. {\texttimes}bruntonii (= I. engelmannii {\texttimes} I. hyemalis) or I. appalachiana {\texttimes} I. engelmannii. Isoetes microvela is a rare species, presently known from only two populations.},
