160 NEW PUBLICATIONS. 
pilosum of Thuillier, which has been found by Mr. H. 8. Fisher in the 
neighbourhood of Liverpool, is worthy of further attention. It is well 
figured in Reichenbach’s ‘Icones, and is said to differ mainly from Æ. 
cicutarium by its invariably and truly bipinnate leaves. We hope on a 
future occasion, as the work progresses, to return to it again. 
Pinetum Britannicum: a Descriptive Account of all Hardy Trees of the 
Pine Tribe cultivated in Great Britain. With Faesimiles of original 
Drawings made for the Work. Edinburgh and London: Private 
press of Peter Lawson and Son. Folio. 
The first three parts of this work have come to hand, and they con- 
tain figures and descriptions of Picea nobilis, Pinus Lambertiana, Picea 
Cephalonica, and Picea Pinsapo. Both the plates and the letterpress, 
especially the latter, are done satisfactorily; and the only incon- 
venience of which working botanists have to complain is, that the 
plates are not numbered and the letterpress is not paged consecutively, 
so that on the completion of the work it will be difficult to find a 
plant. The dissections on the plates ought also to have been lettered. 
At the close of the ‘Pinetum ° a. synoptical table will be printed, in 
which all the species of Conifere hardy in Great Britain will be classi- 
ed. We regret not to find the name of the author on the title-page, 
as it would have imparted to the work a scientific value to which no 
anonymons publication, however ably executed, can lay claim. His 
name has been mentioned to us, but as there were probably sound 
reasons for not making it public, we refrain from repeating jt. We 
shall return to this work after more parts have been issued.

Species Filicum. Part XVII. By Sir W. J. Hooker. London: 
Dulau and Co. 
In this part the distinguished author carries the genus Polypodium 
to the 395th species. The work will be completed in the next part, 
now almost réady, when we shall have a complete enumeration of this 
Order of plants, with numerous illustrations of interesting and other- 
wise unfigured species. We defer till then any lengthened notice of 
this important publication, which must be in the hands of every one 
who would do any satisfactory work with Filices.
