320 NOTICES OF BOOKS. 
Now ** Hooker," following immediately on the name of the plant, would 
lead to the inference that he was the author of the name, and not 
H. B. K., with whom however it originated. Again, under the same 
plant, “ Adiantum cuneatum, Hook. ;” this should be Hook. fil. In 
quoting M. Fée, the accent is invariably omitted. Cavanilles is written 
Cavanelles. "These errors are pointed out in no hostile spirit. The 
author has much before him; and the work is capable of great improve- 
ment, which we believe an educated gentleman like Mr. Lowe is quite 
capable of effecting, and of thus rendering his book, which is really 
undertaken with the best of motives, and from no love or expectation 
of luere, really useful to horticulturists and lovers of Ferns.

This fine work is continued with great regularity. The sixth Fasciculus 
is now before us, containing Tab. 18, Lastrea rigida, with its numerous 
the middle and south of Europe, extending to Asia Minor and to Siberia. 
The Aspidium argutum of Kaulfuss, from California, is pronounced to 
be the same, and it is a native of Massachusetts, on the east side of 
North America. 
Tab. 19 admirably represents the normal state of Lastrea cristata ; 
Tab. 20 the var. uliginosa (Lophodium uliginosum, Nem.) from Oxton 
Bog, Nottinghamshire. The two left-hand figures are derived from 
_ authentic specimens, which were communicated to the authors of the 
x British Flora,’ and which they also refer to a state with broader and 
more deeply-divided fronds, of Aspidium (or Lastrea) cristatum, in the 
seventh edition. The right-hand figure in the plate, however, has à 
. very different aspect; and, unless ascertained that it is derived from 
one and the same root with the left-hand specimens, would seem to 
deserve to be noticed as a third variety; or possibly it may be a separate 
species, and one of the states of Asp. spinulosum, as defined by Hooker 
and Arnott. In outline it resembles the 4. cristatum, in composition 
the 4. spinulosum. We shall be glad to see how Mr. Moore will treat 
his Lastrea spinulosa, which is here indicated “ Var. spinulosa” under 
L. cristata, but reference is made to L. spinulosa (Plate XXL) as 4 
synonyms; for, though a rare plant in Britain, it is not unfrequent in .
