CONFERVA isogona.
Equal-jointed Verdigrise Conferva,.
CRYPTOGAMIA Alga.
Gen. Char. Seeds produced within the substance of
the capillary or jointed frond, or in closed tubercles
united with it.
Spec. Char. Green. Filaments unbranched, straight.
Joints all equal, scarcely so long as broad; their
partitions pellucid and constricted.
COMMUNICATED from the piers of Yarmouth jetty by
Mr. Turner and Mr. W . J . Hooker in March last.
It appears to be a nondescript species, very nearly allied to
C. area, t. 1929, but differing in the following particulars.
Its size is very much smaller; its colour less inclining to
glaucous ; its joints are all uniform and equal, their edges by
far less disposed to become pellucid than in cerea, and never
so but in decay. The interstices are indeed, as in that, colourless
very soon after the plant is taken out of the water,
and are at all times so constricted as to give a beaded aspect
to the filament.
