ASPLENIUM SERPENTINI, Tausch, A RECENT ADDITION 
TO THE BRITISH FERNS. 
. It may be interesting to the readers of the ‘Journal of Botany’ to 
learn that the true Asplenium Adiantum-nigrum, var. obtusum, has been 
found in Great Britain. By the true od¢usum is meant the Asplenium 
obtusum of Willdenow, and the Asplenium Serpentini of Tausch, which 
are synonymous, included by Heufler under the name of 4. Adiantum- 
nigrum Serpentini. This Fern, not hitherto recorded as British, was. 
sent to me last autumn, by Mr. A. Christie, from the serpentine rocks 
in the Banffshire and Aberdeenshire divisions of the parish of Cabrach. 
I hope to be able to give in this Journal a more complete notice of this 
interesting plant at some future time, and in the meanwhile send this 
brief record of the fact of its discovery.—Tuomas Moore.

VIVIPAROUS REPRODUCTION OF S4GINA4 NODOSA. 
In the * Bulletins de la Société Royale de Botanique de Belgique,’ i 
160, M. J. A. Henrotay gives an interesting account of his having disco- 
rere that the fascicles of leaves found upon Sagina nodosa do not de- 
cay at the same time as the stems upon which they grow, and the larger g —— 
leaves in the axils of which they are produced, but live through the 
winter, root, and produce the rosettes or “ primary stems” of indepen- 
dent plants in the succeeding spring. He noticed that the plant 
rarely ripens any seed, and that the species is therefore chiefly repro-
