for fuller particulars and a further analysis. In our plate, fig. 3
is a little out of proportion, the sheaths and filaments being too
short in proportion to their breadth, a distortion arising from
their having been strongly pressed between glasses, for the
purpose of separating them. Professor Kiitzing, who has founded
the genus, describes no less than thirty-two species, several of
which, probably, may be detected in this country. Whether
om- Ä JFarreniee be referable to any of those enumerated, I
cannot say, not having had the opportunity of comparing
specimens; and being unable to determine the point from the
author’s short descriptions, in reading over which one is tempted
to believe that the thirty-two might well be reduced at least one-
half. Be this as it may, the plant now figured was added to
our Plora by Dr. Caspary, and has been named by him in
honour of Miss Elizabeth B. Warren, of Palmouth, a lady whose
researches in natural history amply entitle her to this compliment.
