MONOGRAPHIE DES BERNINAGEBIETES 351 



(one year ten specimens were counted) ; but is very erratic as to 

 the part of the field in which it appears. I need hardly say that 

 strict watch is kept over it, and the owners will not allow it to be 

 gathered. — Arthur Bennett. 



Arenaria leptoclados var. viscidula Eouy & Fouc. — I have 

 lately found this plant at Gwbert-on-Sea, Cardiganshire. It was 

 named for me by Mr. Hiern. — A. Wood Morris. 



Prunella laciniata in Hants. — In the Selborne Magazine for 

 April Mr. F. A. Keddie writes from Brockenhurst that he has 

 found there both cream-coloured and purple varieties of Prunella 

 laciniata, the naming being confirmed at the National Herbarium. 

 He also records Neottia Nidus-avis and Sparassis laminosa.

PflanzengeographiscJie Monograyhie des Berninagehietes. By Dr. 

 E. KiJBEL. (Reprinted from the Botanische Jahrhucli, vol. 

 xlvii. pp. 615, with an ecological map, coloured frontispiece, 

 fifty-eight whole-page plates of vegetation, and twenty 

 figures in the text.) Leipzig : Wilhelm Egelmann. 1912. 

 Price 8 marks. 

 This is an excellent example of those intensive studies of the 

 flora of a small area that we owe to the ecological standpoint of 

 the present century. The many visitors to Pontresina and its 

 neighbourhood may well be glad of a guide to its plants ; but this 

 somewhat bulky and weighty volume is far more than the average 

 tourists' flora. The third and concluding part of the work 

 (pp. 297-545) is occupied by a flora, in which Dr. Riibel has 

 secured the assistance of Dr. Herzog for the Mosses, Professor 

 Lindau for Lichens, Dr. Volkart for Fungi, and Dr. G. Huber for 

 Plankton. A special feature of this section is that most species 

 are individually referred to the various constituent elements of 

 the flora. The first part, however (pp. 4-86), contains a detailed 

 discussion of the local ecological factors, in three chapters, dealing 

 respectively with the geography, climate and geology of the 

 region, the last being by Dr. Blosch ; and the second (pp. 86-296) 

 treats of the vegetation under its various types, formations, and 

 associations, separate sections being devoted to forest, underwood, 

 upland, grassland, moorland, freshwater, and rock floras, the 

 influence of soil receiving full treatment under the last head. 

 The vertical distribution and the geographical origin of the various 

 elements of the flora are here discussed. Each of these sections 

 of the work is thoroughly equipped with all necessary tables and 

 curves. The large-scale folding contoured map, in which, by a 

 judicious use of various forms of coloured shading, some twenty 

 different "tints " are obtained, separating, for example, tall Pinus 

 montana from the stunted form of the same species, and indicating 

 by a special colour the " Curvuletum " or Association of Carex 

 curvula, is alone worth almost the whole of the very small price 

 asked for the volume. Some of the illustrations of one or two
