My principal motive in remarking on Mr. Archer’s papel on Palmoglœa macrococca was not so much to question the independent existence of the forms of which he wrote, as to urge him to direct his unfettered attention to the study of these forms in their life-history ; and also to rouse the attention of Algologists to the unstable basis on which the genera of so many of these lower forms were resting. I am glad to find that, to a considerable extent, Mr. Archer agrees with the observations then made, though he appears yet to hold that there are some plants which can always be recognised by the eye, although it is difficult to convey the exact appearance by word or drawing. No doubt this is so ; but yet it must be admitted as a very insecure basis on which to stand.
