Eleocharis acuminata (Muhl.) Nees, a characteristic species in 
calcareous regions of northern New York, should be sought in western 
New England, especially in northern Vermont. 
E. Engelmanni Steud. and its var. detonsa Gray, although very local 
in our region, are to be expected throughout southern New England. 
E. intermedia (Muhl.) Schultes is common in wet calcareous soils 
in the northern half of Maine and frequent in northern Vermont. 
It should be sought in such places, especially marly bogs, in northern 
New Hampshire. 
E. intermedia (Muhl.) Schultes, var. Habereri Fernald, now known 
only from the shores of Oneida Lake, New York, should be sought 
throughout the range of the species. It is distinguished by its lack 
of perianth-bristles. 
E. interstincta (Vahl) В. & S., extending from "Tropical America 
along the coastal plain to ponds of Rhode Island and eastern Massa- 
chusetts is likely to be found in southeastern Connecticut. 
E. melanocarpa Torr., likewise, is a coastal species, found in south- 
eastern Massachusetts, in Rhode Island and on the eastern end of 
Long Island. It is, therefore, probable that it reaches southeastern 
Connecticut. 
E. ovata (Roth) R. & S. is found in wet, places in northern Maine 
and northern Vermont. In Maine it apparently prefers calcareous 
soils and it should be looked for in such soils in northern New Hamp- 
shire. It is readily distinguished from E. obtusa (Willd.) Schultes 
(E. ovata of many American authors, not R. & S.) by its very purple- 
brown scales and by the very narrow tubercle. 
E. palustris (L.) R. & S., var. calva (Torr.) Gray is apparently 
a very local plant and any information as to its occurrence is desir- 
able. 
E. palustris (L.) R. & S., vars. glaucescens (Willd.) Gray and vigens 
Bailey are probably of general distribution in New England. 
E. Robbinsii Oakes is abundant in ponds of the coastal region of 
New England, and it extends inland in the Connecticut valley at least 
to west-central Massachusetts. It should be confidently watched for 
in ponds of southeastern Vermont, especially at low altitudes, where 
occur many other common coastal species, such as Aspidium simula- 
tum, Selaginella apus, Potamogeton pulcher, Cyperus diandrus, Fim- 
bristylis Frankii, Scirpus Torreyi, Xyris caroliniana, Rhexia virginica, 
&с.
