genus Hormotriclum for this latter group, adding to it, as that
author has done, Conferva bangioides, C. Youngana, and probably
C. collabens, a species of which but little is yet known.
In any future work I should probably bring these species together
under one generic head, as they certainly have characters
in common with each other, and such of them as have, like the
present, been classed with the Lyngbyce differ from the type of
that genus in having a distinctly articulated filament.
I have frequently observed C.facca put forth the root-like,
proliferous branches given in our plate.
