ALPINE PLANTS IN THEIE NATIVE HAUNTS.

climate lies entirely beyond our control. We may study the conditions 

 of soil under which the individual species of alpine plants grow in their 

 native haunts, and we may, by careful experiment, learn how best to 

 treat them in this respect in our own gardens. For the rest, we must 

 rely on the capacity which most alpines exhibit for adaptation to new 

 surroundings, and even if, in the course of undergoing this adaptation, 

 they lose some of the beauty which is theirs when growing under their 

 native skies, they are still well worthy of the care which we bestow 

 upon their cultivation.

BOOKS OF REFERENCE. 

 Floras. 



J. Hoffmann. Alpine Flora, for tourists and amateur botanists. Translated 



from the German by E. S. Barton. (Mrs. A. Gepp.) 



This book can be carried in the Riick-sac when touring in the Alps. Its 



coloured plates are probably the best of any flora of small dimensions. 



(Longmans, Green. 7.s. 6cl. net.) 

 C. AND L. ScHROETER. Taschen Flora des Alpen- Wanderers. Another handy 



pocket flora. The coloured illustrations are, however, not so good as the 



foregoing. (A. Ranstein : Zurich. 7 francs 50 cents.) 

 G. Bonnier and G. de Layen. Flore complete de la France et de la Suisse. This 



work contains a very complete and carefully systematized flora of the French 



and Swiss Alps. It is a work of over foiu" hundred pages, and more adapted 



for serious study than either of the foregoing. (Paris : Librairie Generale 



de I'Enseignement. 1908. 11 francs.) 



Books on Alpine Plants. 



C. ScHROETER. Pjianze^dehcn der Alpen. A scientific work containing much 

 information. More for botanists than for amateurs. Published in German 

 only. 



Dr. Christ. Das Pflanzenlehen der Schweiz. A classical work on Alpines 

 in their native haunts. Charmingly written, but not yet translated into 

 English. A French edition can, however, be obtained. (H, Georg : Bale, 

 Geneva, and Lyons. 15 francs.) 



E. A. Newell Arber, M.A., F.L.S., F.G.S. Plant Life in Alpine Switzerland. 

 An admirable work. Quite the best book written in the English language 

 for amateur botanists to read. It gives an admirable summary of the results 

 of the experiments of Kerner and Bonnier. (John Murray. 1910. 7s. 6d.) 



Books on Plant Physiology and Ecology which deal with Alpine Plants-. 



A. Kerner. The Natural History of Plants. A work of the very first 

 importance. Translated from the German by F. W. Oliver, M.A., D.Sc. 

 (Blackie & Son.) 



A. F. W. ScHiMPER. Plant-Geograpliy. An important work on the ecology 

 of plants, containing several chapters on the mountain climate and vegeta- 

 tion. Translated from the German by Percy Groom, M.A., D.Sc, F.L.S., 

 and Isaac Bayley Balfour, M.A., M.D., F.R.S. (Clarendon Press. 1903.) 

 Gaston Bonnier. Le Monde Vegetal. In chapter 10 the author gives an 

 account of his most interesting experiments in cultivating plants under 

 artificially created Arctic and Alpine conditions. In French, not trans- 

 lated into English. (Paris : Ernest Flammarion. 1907. 3 francs 50 cents.) 



I Leclerc du Sablon. Traite de Physiologie Vegetale. Contains a concise sum 

 mary, page 485 et seq., of the latest opinions of the modern French school of 

 botanists on the effect of the Alpine climate upon vegetation. (Paris : 

 Librairie J. B. Bailliere et Fils. 1911.)

 with Ecology. (Clarendon Press. 1909. 8s, (id. net.)
