BOOK-NOTES, NEWS, dc. 



We have received from Mr. Upcott Gill the second and con- 

 cluding part of the Century Supplement to the Dictionary of Gardening, 

 of which the earlier portion was noticed on p. 48. We have already 

 expressed our opinion of the merits and demerits of the work, the 

 former of which greatly outweigh the latter. The coloured plate of 

 daffodils, which faces the ugly title-page, is a disfigurement rather 

 than an ornament to the book — a criticism which applies to several 

 of the illustrations in the text — and is made uglier by the blue 

 lettering employed ; and some of the information given — e. g. as to 

 the apparatus used for "spraying" — reads like an advertisement. 

 We note many references — e. g. under Quercus — to the discrepancies 

 m nomenclature between the '' Kew Hand-list" and the Index 

 Keivensis. 



It is announced that Prof. C. E. Sargent's Silva of North America 

 will be supplemented by two extra volumes, containing plates and 

 descriptions of trees added during the last ten years to the region 

 covered by the work. The new volumes will contain 115 plates, 

 and will be published next spring. 



Messrs. W. & G. S. West are issuing in the Transactions of the 

 Yorkshire Naturalists' Union a localized list of tbe freshwater algae 

 of the county. A hundred pages of the list, embracing 470 species 

 and many varieties, have already been issued, this being less than 

 half the number to be recorded. Many species are recorded for the 

 first time in Britain. The authors give those synonyms which they 

 consider will be useful to future workers, and they express a hope 

 that the list " will be deemed worthy to form an acceptable and 

 substantial basis-list, serving as a useful guide to future workers 

 both in the matter of the classification of these plants and in the 

 species they may expect to find." Judging by the numerous 

 localities under a large number of the species, much of the ground 

 seems to have been well worked. It is probably the most complete 

 list of fresh-water nlgse ever issued for any district. 



The first part of vol. viii. of the Flora of Tropical Africa has 

 been issued. The following botanists have contributed : Mr. N. E. 

 Brown {Pontederiacece, Xyridea, Aroidea) ; Mr. C. B. Clarke (Com- 

 melinacecB) ; Mr. J. G. Baker (Juncacea) ; Mr. C. H. Wright {Palmea
