240 THE JOURNAL OP BOTANY 



on p. 40, in interest. More than half of it is occupied by an 

 account of Mr. R. P. Gregory's experiments with Primula sinensis, 

 undertaken by himself and Mr. Bateson, of which some account 

 has already been published. The present paper deals with the 

 inheritance of heterostylism and of colour, especially the latter, 

 which is illustrated by three excellent plates (two of them coloured) 

 from what are evidently accurately described as "the beautiful 

 and accurate water-colour drawings of Miss M. Wheldale, of 

 Newnham College." The question of colour is discussed with 

 regard to the stem as well as the flower. Miss Wheldale herself 

 contributes an important paper on the formation of Anthocyanin, 

 the ultimate object of the inquiry being the identification of the 

 Mendelian factors for colour. The Journal, which is beautifully 

 printed by the Cambridge University Press, costs ten shillings net ; 

 the subscription for four numbers is thirty shillings. 



The Twenty-first Report of the Missouri Botanical Garden is 

 largely occupied with papers relating to cryptogams. Miss Ada 

 Hayden writes on the Algal Flora of the Garden ; Mr. Perley 

 Spaulding on Botrytis on Chrysanthemums and Poinsettias and 

 on the fungi of clay mines ; Mr. C. H. Danforth on periodicity in 

 Spirogyra ; and Mr. E. G. Arzberger on the fungous root 

 tubercles of various trees. Mr. David Griffiths continues his 

 useful studies on Opuntia, of which he describes and figures 

 several new species ; Mr. R. R. Gates writes on abnormalities in 

 Oenothera ; and Mr. F. E. Lloyd contributes the longest paper in 

 the volume, on the development and nutrition of the embryo, 

 seed, and carpel in Phcenix dactylifera. 



The Lloyd Library of Cincinnati issued in April as one of its 

 "Bibliographical Contributions" a "Bibliography relating to the 

 Floras of Europe in General and the Floras of Great Britain." 

 The second part of the subject is very fully treated, and the list 

 forms a useful foundation for that more complete enumeration 

 which we had always hoped to persuade the late W.-A. Clarke to 

 undertake. It is very well and correctly printed, arranged under 

 the authors' names; to these we regret that the dates.of birth and 

 death, in most cases easily ascertainable, are not attached, in 

 accordance with the useful custom which is now prevalent in lists 

 of the kind. 



The Education Department of Wellington,, New Zealand, has 

 reprinted in a neat little volume entitled New Zealand Plants and 

 their Story some papers contributed to periodicals by Dr. L. 

 Cockayne. They are informing and pleasantly written, but their 

 chief interest lies in the 71 illustrations, taken from photographs, 

 showing aspects of the vegetation of the forests, meadows, coast, 

 &c., as well as individual plants. The book is well calculated to 

 foster a taste for botany among youthful New Zealanders. 



A HANDSOME Catalogue of the Botanic Garden at Buenos Aires 

 comes to us from Senhor Carlos Thays, its founder and director. 

 It is well printed and fully illustrated with views of the Garden 

 and pictures of special plants contained therein.
