CLADOPHORA GATTYÆ, n. sp.
C la d om io k a Gattyoe; filaments an inch long, dingy-green, capillary,
matted together in dense tufts, not much branched, dichotomously
divided, flexuous, with few ramuli ; articulations in all parts of the
frond nearly uniform, about once and half as long as broad, filled
with endochrome ; th e dissepiments very narrow, contracted.
H a b . On rocks (?) near low-water mark. Locality uncertain, Mrs. Gatty.
Descb. Filaments about an inch long, as thick as human hair, or somewhat
thicker, matted together in dense ropy tufts, irregularly branched, somewhat
dichotomous, the angles rounded ; ramuli few and patent. Articulations
very uniform, about once and half as long as broad; filled with olivaceous
(?) or dull green endochrome, and separated by exceedingly narrow
dissepiments. Apices on my specimen often broken,
branaceous, adhering to paper.
A puzzle, figured with the hope that it may lead to more
certain information. The external habit is between that of
C. uncialis and Ectocarpus Uttoralis, but the threads are very
much more robust than in the former; and diiferently branched
from the latter, as well as more robust. The plant is, however,
much battered and water-worn, having most of its upper
branches and ramuli broken off:—^and I am not prepared to
say whether it be not some species in a dilapidated condition,
whose proper character is thus concealed, or as it were shown
in caricature.
