Decidedly the same as the European aud North American plant.

C. Plumulæ simiUimum, sed rigifliusculum, ramis latioribus, ramulis robustioribus articulisque brevioribus.
This so closely resembles the C. Plumula, that it is difficult by mere words to discriminate them ; yet, ou
comparing them under the microscope, they are obviously distinct. C. simile is a much coarser and more rigid
plant, -with the ramuli more robust in proportion to tbe diameter of the articulation they spring from, and the articulations
themselves are shorter. Again, from the circumstance of the tme C. Plumula occurring at Cape Horn, where
this, (the only Kerguelen’s Land species), does uot appear, we incline to regard the present as a representative
species rather than a variety.
