full descnption is given of tlie methods of planting (roots), various 

 types, special uses (pasture and lawns), and field trials of this grass. 

 It compares favourably with timothy, and does well with white clover. 

 This grass {Cynodon Dactylon) seems to be thoroughly hardy at 

 Oklahoma. — G. F. S.-E. 



Bohemia, Flora of. By Dr. Karl Domin {Beih. Bot. Cent. 

 xxvi. 2. Abt. Heft ii. pp. 247-287 ; with 2 tables and 7 text figs. ; 

 2910). — This paper gives some interesting notes on the plant associa- 

 tions of Bohemia, and a critical discussion of some of the more difficult 

 species. Several new varieties are described, and also a new species 

 of Oarex (C. Valenovskyi). 



Perhaps the most interesting varieties are those of Primula offici- 

 fialis, of which one {montana) has flowers 17 to 20 millimetres in 

 diameter. 



Other varieties of interest are those of Scorzonem hispanica, 

 Anemone nemorosa, Raphanus Raphanistruiii, &c. — G. F. S.-E. 



Bolivia, Mountain Flora of. By Dr. T. Herzog {Beih, Bot. 

 Cent. xxvi. 2. Abt. Heft i. pp. 45-102 ; with 3 plates and 16 t.ext figs. ; 

 1909). — This paper is of very great importance to bryologists, but it 

 is also exceedingly interesting to other botanists. The brief sketch 

 which he gives of the affinities and distribution of the Bolivian mountain 

 flora is not only important but unusually clear. 



On the south slopes of the Cordillera are dry and arid mountain 

 steppes, which change towards the base into a flora of thorn shrubs 

 and giant Cacti. The northern sides of the Cordillera are absolutely 

 different. 



Here one finds lovely alpine meadows full of flowers, interrupted 

 here and there by some moss-covered rock. At from 3000 to 2900 

 metres is a " Krummholz " region, rather like the zone of Alpine roses 

 and alders found in the Alps. This is a transitional formation between 

 the alpine cushions and the mountain woods. There is luxuriant tree- 

 growth even at 2800 metres, especially in the steep-sided mountain 

 valleys. This mountain forest (2700-2000 metres) is low-growing, 

 very thick, and characterized by an extraordinary development of 

 epiphytes. The mosses are more abundant even than in Ceylon. 



In one place he gathered 113 species in two days, which would, 

 he thinks, have been impossible even in the richest valley in the Alps.

Brown-rot and Plum Curculio on Peaches, Control of the. 



By W. M. Scott and A. L. Quaintance {U.S.A. Dep. Agr., Bur. 

 Entom., Giro. 120). — The punctures on the fruit caused by the 

 plum weevil {Conotrachelus nenuphar Herbst.) in the course of its 

 feeding and egg-laying form a resting-place for the spores of the fungus 

 of brown rot {Sclerotinia jructigena (P.) Schrot.) and greatly favour 

 infection. The authors stare that both these troubles can be prevented
