g between each furca-tion ; that is to say, every internode consists of a single cell.There is no other British species in which this takes place regu-larly, in all parts of the frond. It thus happens that the indi-vidual cells, ill this species, are of extraordinary length, those ofthe lower parts of the filament being sometimes more than aninch in length, very frequently three quarters of an inch. Conferva pellucida was first described by Hudson, in the FloraAnglica, and has been adopted by all subsequent authors withthe exception of Lyngbye, who unaccountably confounds itwith C. rupestris, a plant which is well distinguished by thedifference in its articulations, if there be no other character, asthere are many, to separate it. Hudsons expression articuliscylindricis longissimis, is alone characteristic of C. pellucida. Fig. 1. Cladophora pellucida:—of the natural size. 2. Portion of a branch:—magnified. 3. Terminal articulation of the same :—more highly magnified. Plate Til.
