CRYPTOGAM1A Algce.
Gen. Char. Seeds produced within th e substance of
th e capillary or jo in ted frond, or in closed tubercles
united with it.
Spec. Char. Dark green, ascending, tufted. Filaments
simple, cylindrical, even, without any
visible jo in ts .
C o m m u n ic a t e d to Mr. Sowerby, by the Rev. Dr. Davies,
who observed it in the celebrated warm waters of Bath, Somersetshire,
spreading, rather unequally, in broad velvet-like patches,
of a dark green colour. The irregularity of its appearance arises
from the filaments being collected together into little ascending
tufts, apparently rooted in the muddy deposit of the water. Each
tuft proves, on examination, to consist of simple, uniform, even
filaments; crowded together, quite pellucid, and equally destitute
of joints and branches. Their diameter is not more than eight or
ten thousandth parts of an inch; this being one of the most
minute species that we have examined. We can refer it to none
in Mr. Diilwyn’s work.
