adding another synonym to the six already perpetrated by Euro- 
pean bryologists for the varieties of this much-abused American 
species. We note three ew species (?) from eastern localities, all 
of which are cited with his usual clearness and succinctness, 
Drummondia canadensis, Weisia pusilla and Grimmia Austini. He 
also founds a new genus to include M/nium lucidum and M. simplex 
in the following words: 
“The both species are very differing from the other ones of 
Mnium that they are consisting at least a subgenus (or rather a 
proper genus), to which I propose the name Xoe//ia to the honor 
of Dr. J. Roell.” E. G. B.

The author proves conclusively that the habit of reproduc- 
ing asexually is not confined to the leafy moss-plant, but is also 
resorted to by the protonema, which forms irregular masses of 
gemmae, differing from the regular cup-shaped ones which are so 
characteristic of this genus. He disagrees with previous writers 
in attributing the gemmae to modified antheridia, claims that they 
originate from the paraphyses, and states that the green globose 
terminal cell of the paraphyses in /unaria, is a step in this direc- 
tion. He places the Georgiaceae between the Andreaeceae and the 
Bryineae, as a well-marked and distinct group. He also studied 
the gemmae in Webera annotina, Orthotrichum Lyelli, O. obtusifoliun, 
Encalypta streptocarpa and Zygodon viridissimus. + BGs Be

This series of papers is to include only the mosses of France, 
it seems, though the author does not say so. He proposes to re- 
view the works in the following order, first those treating of geo- 
graphic distribution ; second, the descriptive works ; third, those on 
anatomy, and lastly, those on the physiology of the Mosses. He 
solicits contributions from authors. E. G. B.
