H a b . Observatory Inlet, N. W. America. D r Scouler.— Neatly allied, as Dr Torrey well observes, to
S. sylvaticus, (indeed I think it can hardly be specifically distinct from that species, or atro-virens), “ but
differs in its laiger spike, lenticular nuts, diandrous flowers, and bifid style.”—The true S. sylvaticus has a
lenticular seed, and the other characters are perhaps variable.

Drummond.—/3. Saskatchawan.—y. Newfoundland. Mr Cormack. Lake Huron. Dr Todd—This is certainly
a. highly variable species, not only in the length of the leaves, which are generally shorter, though
sometimes twice as long as the culms, but also in the spikes, which, according to some of Mr Drummond’s
specimens, do vary not only in the length of the hairs, but also in the form of the spike, being sometimes
oblongo-ovate, and sometimes spherical. Thus I am not surprised at Dr Torrey, who. remarks in his valuable
account of North American Cyperacece, that E. capitatum is very difficult to be distinguished from E.
vaginatum.

H ab. Canada to Arctic America.—I have the same difficulty in determining the limits of the many-spiked
Eriophora of North America, as regards those of Britain (as expressed in Brit. Flora, ed. 4. p. 30), E.
Virginicum alone excepted. Dr Torrey indeed observes, that the present species is easily distinguished
from E. polystachyon by its narrow triangular leaves, one-leaved involucre, and narrow nut. This is the case
with the extreme states of the plant; but Dr Torrey proceeds, “ Mr Brown thinks that the Arctic plant,
collected in Parry’s 1st voyage, may prove a distinct species, between E. angustifolium and E.polystachyon;"
and further, “ he notices two varieties of it, one with smooth, the other with scabrous peduncles,”—thus appearing
to include the E.pubescens of Smith.
