REVIEWS AND BOOK NOTICES. 



Students' Handbook of British Mosses. By H. N. Dixon, M.A., 



F. L.S. With Illustrations and Keys to the Genera and Species by H. Q. 

 Jameson, M.A. Second edition revised and enlarged ; pp. xlix. + 586 

 and 65 plates. Eastbourne: V. T. Sumfield. r8s. 6d. net. 



The appearance of a second edition of this invaluable hand- 

 book testifies to its popularity. Since the first edition was 

 published in 1896 thirty species or sub-species have been 

 detected, tog"ether with numerous varieties ; these have been 

 included and are illustrated by five new plates. Two of the 

 new species figured are Tortiila cerniia Lindb., found by Mr. 



G. Webster at Aberford, and Tetmplodon IVorfjiskjoldii Lindb. 

 from Widdy Bank FelL Among- the new varieties are several 

 from Yorkshire and Lancashire, discovered by Messrs. Ingham 

 and Wheldon. Numerous changes have been made and some 

 genera have undergone considerable revision, viz.: — Sphagnum, 

 the Systegium section of Weisia, Pottia, and the Harpidioid 

 Hypna ; in the latter Mr. Wheldon's paper in 'The Naturalist' 

 (1902, p. 65), receives due acknowledgment. Other alterations 

 found in this edition, and which students will fully appreciate, 

 are the insertion of the derivations of the generic names, and in 

 the index the pronunciation of both generic and specific names 

 is indicate"H. The index is further improved by the addition of 

 the page number to each genus. In all the text of this edition 

 is increased by 60 pages. The work is indispensable to and 

 ought to be in the hands of all students of British mosses. 



Manual of British Botany. By the late C. C. Babington, M.A., 



F.R.S., &c. Ninth edition. Edited by H. and J. Qroves. Pages lii. + 

 580. London : Gurney & Jackson. 9s. net. 



A special interest attaches to this edition, the primary object of its issue 

 being- to publish the notes in the late Prof. Babing-ton's interleaved copy of 

 a former edition. Owing- to Mrs. Babington's particular wish that the text 

 as amended by the late author should not be interfered with the editors 

 have not been able to make alterations in the treatment of some of the 

 critical g-enera which mig-ht have been desirable. Still many important 

 additions have been made. An entirely new account of the g-enus Hieraclum 

 has been drawn up by Miss R. F. Thompson under the direction of Mr. F. J. 

 Hanbury. In the g-enus Rubus we have in addition to Prof. Babing-ton's 

 account, an appendix containing a conspectus of the groups and species 

 from the Rev. W. Movie Rog-ers' ' Handbook of British Rubi,' while the aid 

 of Messrs. Fryer and Townsend has been secured with Potomogeton and 

 Euphrasia. In following the law of priority, many chang-es in nomenclature 

 appear, some very unfamiliar ; let us hope it is a step near finality. In the 

 synopses of Natural Orders and also of the genera at the head of each 

 order it would have g-reatly facilitiited reference if the page number had 

 been given. Great care has been taken by the editors, with the assistance 

 of manv specialists, to bring- this edition up to date, and it will be welcomed 

 by all field botanists.
