120 THE JOURNAL OF BOTANY 



Several papers have been published in recent years by Prof. W. 

 A. Setcheil and Dr. N. L. Gardner on the marine algte of Western 

 America. These results are now being combined by the authors into 

 a complete account of the flora, the first part of which is issued under 

 the title — The Marine Algce of the Pacific Coast of North America^ 

 Part I. : Mg.rophi/cece (University of California Publications, Botany, 

 viii. 1919, pp. 1-13S, 8 plates) ; and the three remaining parts are 

 stated to be in advanced preparation. The Myxophyceae contain 

 thirty genera, under Avhich are placed ninety-six species and some 

 varieties. These are all clearly and concisely described, and are often 

 illuminated with valuable critical notes. Further, the identification of 

 specimens is facilitated by the keys provided. Judging from the present 

 part, this monograph, long needed, will provide a complete and most 

 valuable account of the algae of the west coast of Noi-th America. — A. G. 

 The second part of the Account of the Herharium of the 

 Vniversitij of Oxford, by S. H. Vines, M.A., and G. C. I)ruce, 

 LL.D., which has lately been issued by the Clarendon Press, contains 

 an Index of contributors to the Herbarium and of other collections 

 existing in Oxford, on which there are interesting notes. They 

 include volumes at Merton College, collected by Robert Huntingdon 

 and Charles Willughby in the seventeenth century ; two herbaria 

 bequeathed to Wadham College by Richard Warner (1713 ?-75) ; the 

 herbarium of Edward Morgan (fl. 1639-72) and that of Sir George 

 Wheler (1650-1724)— these at the Bodleian. 



The Adventive Flora of Tweedside, by Ida M. Hayward, F.L.S., 

 and George Claridge Druce, LL.D. (Arbroath, Buncle) is an exhaustive 

 account of the adventitious or alien flora of Tweedside which during 

 recent years has attracted much notice. The work, which is fully 

 descriptive and is prefaced by a useful introduction, contains much 

 interesting matter, but as a copy has not reached us for review we 

 must content ourselves with calling attention to its publication. 

 Dr. Thellung, to whom the book is dedicated, has lately published 

 (Mitth. Bot. Mus. Zurich, Ixxxiii.) a third instalment of his " Beitrage 

 zur Adventivflora der Schweiz." 



The Kew Bulletin (No. 1, 1920 ; March) contains papers on 

 *' The Indian Species of Mimosa,'", by J. S. Gamble, which includes 

 descriptions of three novelties : on the seeds of Momordica cochin- 

 chinensis ; on '' Clematopsis, a primitive genus of Cleraatideae," by 

 Mr. J. Hutchinson, mth five new species ; " Diagnoses Africanae," relat- 

 ing to various orders : a note on "the Rev. H. F. Tozer [1829-1916] 

 and plants collected by him in the Nearer East " ; and a notice of Sir 

 William MacGregor (1846-1919), whose plants, like those of Tozer, 

 are at Kew. 



The vacancy in the Regius Professorship of Botany in Aberdeen 

 University, caused by the death of Prof. Trail, has been filled by the 

 appointment of Mr. W. G. Craib, who has lately been lecturing on 

 forestry in Edinburgh under Prof. Balfour. Mr. Craib was at one 

 time Superintendent of the Calcutta Botanic Gardens, and on his 

 return to England became Assistant for India at Kew. 



The Transactions of the Perthshire Societi/ of Natural Science, 

 vol. vii. pt. 1. contains a list of the Biscoini^cetes of Perthshire by 

 Mr. James Menzies.
