A Supplement to Saines' Flora of Yorkshire ; with a Map. The Flowering 

 Plants. By John Gilbert Baker. Tlie Mosses. By John Newell. London : 

 Pamplin. 8vo. pp. 188. 



It is with sincere pleasure that we notice the appearance of a Supplement to 

 the valuable Flora of Yorkshire, by Henry Baines, which was published in 

 1840. The original work contained a long list of Flowering Plants, Ferns, 

 and Mosses, and an extensive series of localities for all the rarer species was 

 given : in addition to which, on many occasions, the peculiar insects to be 

 found on a plant were mentioned ; thus rendering the book a very much 

 more intei-esting one to the general Naturalist than any other Flora with 

 which we are acquainted. During the fourteen years which have elapsed 

 since the publication of the Flora, considerable additions have been made in 

 both departments of the work; and these additions, together with the 

 progress of Botanical Science, by whicdi species and varieties have been 

 better discriminated, rendered the issuing of a Supplement, if not necessary, 

 certainly most desirable. Under these circumstances Mr. Baines determined 

 to bring out the present work, and, as he states in a prefatory note, " Mr. 

 Baker, with the assistance of Mr. Nowell, having with great kindness under- 

 taken the management of the matter, (a task for which their labours in the 

 special field of research, and their acquaintance with the general literature of 

 the subject have rendered them so eminently fitted), I may with confidence 

 introduce the Supplement which they have furnished to the notice of my 

 friends and the public, as exliibiting not only a very complete list of the 

 botanical treasui'es of the county, so far as it professes to treat, but also as 

 a work calculated to lead its readers to the study and investigation of general 

 principles." The Supplement commences with a few pages of inti-oductory 

 remai-ks, explanatoiy of the plan adopted in the work, together with a general 

 summary of the contents ; and this is followed by an interesting Essay, by 

 Mr. Baker, on the Physical Geography of the County. We then liave a list 

 of all the Flowering Plants and Ferns which have occurred in Yorkshire, the 

 ai-rangement of the genera and species being that of the fourth edition of 

 the Catalogue of the London Botanical Society. In this section we have 

 1155 species enumerated, of Flowering Plants, and 53 Ferns ; the British list 

 only including 1445 and 60. Numerous localities are given for the rarer 

 species ; but those for the commoner are omitted. The work is in fact what 

 it purports to be, a Supplement; and although a valuable addition to, it does 

 not supersede the original Flora, which Avill still be found most valuable for 

 reference. The Plants are ai-ranged under the heads of Native, Denizen, 

 Colonist, Alien, and Incognit; a plan which gives us at a glance much
