CisToPTERIS MONTANA. 
It is well known that Mr. Wilson, of Warrington, dis- 
covered on Ben Lawers, in 1836, the Cistopteris montana, 
Link, (Aspidium montanum, Sw.) Swartz quotes under it, 
Pluk. Phyt. t. 89, f. 4,  Filix alpina Myrrhidis facie Cambro- 
Britannica, &c.,” from which some have inferred that it had 
been previously detected in Wales. We have, with the kind 
assistance of Mr. Brown and Mr. Bennett, searched the 
volumes of Plukenet in the British Museum, but no corre- 
sponding specimens exist there. Buddle’s Herbarium and 
Petivers Herbarium, however, contain Welsh specimens 
(gathered by Mr. Llwyd, in one instance) correspending with 
Plukenet's figure, whose synonym is quoted ; and these plants 
are Aspidium spinulosum, so that to us it appears clear that 
that is the species intended by Plukenet. Mr. Wilson will 
therefore remain the first discoverer of it in Britain. We 
may add, that it is a native of the Rocky Mountains, in North 
America, and, as such, is described in Hook. Fl. Bor.-Ame- 
ricana, 
SALICTUM Brirannicum ExsiccatuM; containing dried 
specimens of the British WiLLows, edited by the Rev. 
J. E. Leere, M.A. Fasc. II. Saffron Walden, 1844. 
Of the importance of this work and of the manner in which 
the author has accomplished the first Part of it, our 
Opinion is recorded in the 1st vol. of this Journal, p. 418, 
and in the 2nd vol. p. 156. The 2nd fasciculus, now before us, 
is executed with the same skill, and the same care is bestowed 
9n the preparation of the specimens as in the former one. The 
Synoptical table is not given with this, but is reserved for the 
third and last fasciculus, towards which some materials are 
already collected. The species are as follows: No. 50. Salix 
decipiens, Hoffm, 51—53. S. fragilis, E. Bot. 54, 55. S. 
Russelliana, Sm. 56—59.S. alba, L. 60—66. S. capræë, L. 
57. S. hirta, Sm, 68—71. S. rupestris, Donn. 72. S. tenuior
