72 THE JOURNAL OF BOTANY 



The recently issued part of the Flora of Tropical Africa (vol. ix. 

 part 2, " 1918 ") continues Dr. Stapf's monograph of the Andro- 

 pogonece. The genus Andropogon is restricted on lines already laid 

 down in the first part of the volume : a large number of the 

 species formerly referred here are transfeiTcd to Hyparrlieiiia, here 

 apparently first treated as a genus although it was adopted as a 

 section by Hackel in his monograph. The name stands as '• [N. J.] 

 Anderss. (name onh'), in Nov. Act. Soc. Scient. Upsal. Ser. 3, ii. 

 254 [1856] " ; it may, we think, be questioned whether it can claim 

 recognition, as it stands only in synon3Tiiy : *^ Anthistiria Pseudo- 

 Cymbaria Steud. = Est Hyparrhenia? sp." A new genus — Dyhowskia — 

 is established for Andropogon Dyhowshii Franch. The species, of 

 which a large proportion are new, are described at great length — 

 many occujjy a page or more : it is not quite easy to see for whose 

 benefit these minutety detailed descriptions, testifying as they do to 

 the carefulness which characterizes Dr. Stapf's work, are intended, as 

 the botanist will, we think, find sufficient for his purpose in the keys 

 to the species, which are very full ; their extent must materially 

 hinder the completion of the Flora, which was begun fifty years ago. 

 "We presume that steps have been taken, as in the case of the Floras 

 of Madras and Jamaica, to secure the validity of the new names by 

 the publication of a Latin diagnosis, in accordance with Art. 3G of 

 International Kules : we note that the adjectival form of names 

 of persons is spelt with a small initial (see Ai*t. 26, Eec. 10). 



The contents of the Journal of Genetics (vol. viii. no. 1) issued 

 January 22 are mainly botanical. They include papers "On tlie 

 Origin of a Mutation in the Sweet Pea," by Prof. K. C. Punnett ; 

 On Hybridization of some Species of Salix " conducted by S. Ikeno at 

 Tokyo (with plate) ; and " Studies of Inheritance in the Japanese 

 Convolvulus," b}' B. Miyazawa (with coloured plate). 



Science Progress for January contains a comprehensive summary 

 of recent botanical research by Dr. E. J. Salisbury, the notices of 

 plant physiology being contributed by Mr. Walter Smith. In the 

 interests of the reader we venture again to call the attention of the 

 editor, Sir Ronald Ross, to the singularly unhelpful and unilluminative 

 headings of the right-hand pages, which with very little trouble might 

 be made of great assistance to those who consult the Review. 



Botanical Abstracts is the title of a new botanical journal, which 

 has been set on foot by American botanists to take the place of the 

 Botanisches Centralblatt, which, for various reasons connected with 

 the War, has become unsatisfactory. It will be conducted by an 

 editorial board, the vanous sections being undertaken by specialists. 



We have received two numbers of the Bulletin of Scientific 

 and Technical Societies, which is issued fortnightly at Burlington 

 House at the cost of i5d. by the Conjoint Board of Scientific Societies. 

 Each number contains a diary of meetings to be held in the fortnight 

 succeeding its publication, with titles of the papers to be read at each 

 and an indication of future meetings. Communications regarding it 

 should be sent to Prof. R. A. Gregorv, 10 St. Martin's Street, W.C. 2.
