ELYMUS viRGINICUS L., var. suBMUTICUS Hook. "There are three 
sheets of specimens of this very pronounced variety in the Club 
Herbarium, all collected in Revere by C. E. Perkins (August 13, 1880, 
and August 11, 1881). The plant is not known from elsewhere in 
New England and is possibly an introduction from the West, but the 
writer is inclined to class it with other species, more common from 
western New England westward, which are well known from Oak 
Island and other sections of Revere (see note under Pedicularis 
lanceolatus). 
ScIRPUS HETEROCHAETUS Chase is known in New England outside 
the Champlain Valley only in eastern Massachusetts. Mr. F. F. 
Forbes has a station of it on banks of the Charles River at Cow Bay, 
Dedham, and the writer has seen it at the margin of the Concord 
River near Carlisle Bridge in Bedford. 
SCIRPUS FLUVIATILIS (Torr.) Gray, another species not commonly 
seen east of the Connecticut River, was collected by Mr. W. H. 
Manning at Brighton (on the Charles River), June 30, 1879. Does 
it still occur there? 
RyNcHOSPORA ALBA (L.) Vahl, var. macra Clarke, a very large 
extreme of the species, more abundant on the coastal plain from New 
Jersey to Florida, is known to the writer from two stations in eastern 
Massachusetts: Fresh Pond, Cambridge, August 20, 1853 (Wm. 
Boott) and the wetter portions of the bog, Round Pond, Tewksbury, 
September 18, 1909 (M. L. Fernald & A. J. Eames). The Tewksbury 
specimens are nearly 8 dm. high, and their principal inflorescences 2 
em. broad. 
CAREX AENEA Fernald, not included in Mr. Joseph Jackson's recent 
(1909) Flora of Worcester County, was collected by Wm. Boott on 
Mt. Wachusett, June 27, 1878. 
CAREX TRISPERMA Dewey, var. BrtuiNGsSH Knight. If one may 
judge by the representation in the Club Herbarium, this recently 
recognized setaceous-leaved variety is about as common in north- 
eastern Massachusetts as the typical broader-leaved form of the spe- 
cies; the latter being represented by eight specimens, the former by 
seven: from Lynnfield, Tewksbury, Littleton, Wakefield and Melrose, 
all north of Boston. But, since the variety extends from the sandy 
bogs of central Newfoundland to the pine barrens of New Jersey, it 
should be expected, also, in the cranberry bogs of southeastern Massa- 
chusetts, a region from which we have altogether too little herbarium 
material.
