as to turn the central bud of each whorl inwards, and to
become so incorporated with the globule as to be indistinguishable,
or possibly to form the outer coat, which seems
distinct from the cells. The rays would then represent
the whorl; the pedestal within, the continuation of the
central stalk or branch ; the filaments new contiguous
whorls, and the bell the central bud. This, however, will
hardly agree with the supposition of the bells being open
at one end. Agardh does not figure them as open, but
implies that they are so ; his expression is, speaking of the
narrow end of the bell, “ an dem geschlossenen oder un-
tern Ende, wo ich die Faden angeheftet gefunden habe”
(p. 140),—“ at the closed or lower end, where I have found
the threads (meaning the confervoid threads) fastened.”
My drawings were made in 1828, and I have had no opportunity
of further investigation since ; but I have no
doubt that I have accurately represented what I saw in
the specimens under examination : the matter, however, is
open to correction.—M. J . B.
Fig. a, Chara Hedwigii; b, one of the branchlets with its
nucules and globules magnified; c, a morsel of Nitella
Jlexilis magnified; d, e, the globule ; f one of the triangles
seen from within, with its pedestal; g , pedestal when dry;
h, cup with pedestal and filaments ; k, cup and filaments
without pedestal; l, filaments and granules. The larger
figure of the plant, with the accompanying representation
of part of one of its ramuli, is from a specimen gathered
by Mr. Borrer, at Henfield, in June 1826.
