 gen. Bot. XXI. p. 257—273. 1909.) 



Un bref apergu orographique et geologique precede la descrip- 

 tion des etages entre lesquels se repartit la Vegetation de la chaine 

 des Grandes Rousses dans les Alpes du Dauphin e. L'auteur 

 aborde ensuite l'analyse des principales associations et dresse le 

 catalogue de la flore alpine du massif d'apres ses recherches et les 

 travaux anterieurs de Ravaud, Gaston Bonnier, Cariot et 

 Saint-Lager, etc. Quelques especes sont specialement etudiees au 

 point de vue de leur distribution geographique. Enfin l'auteur com- 

 pare la flore des Grandes Rousses avec celle de la chaine voi- 

 sine de Belledonne, beaucoup moins riche en plantes rares et 

 essaye de determiner les causes des particularites fioristiques de 

 chaque massif. J. Offner.

Rankin, W. M., The Peat -Moors of Lonsdale. (The Natu- 

 ralist. 638 — 639, 12 pp. 86 figs. 1910). 



Lonsdale, the drainage area round Morecambe Bay in 

 north-west England, includes a number of peat moors, some of 

 which are lowland near sea-level, others being upland. In this 

 introductory paper the upland moors are briefly referred to as they 

 do not differ much from those already described by other recent 

 writers. With regard to the lowland peat moors, the author distin- 

 guishes two groups according tp development: lacustrine moors in- 

 clude plant accumulations in and around small lakes; littoral moors 

 are developed in long silted-up Valleys which formerly extended as 

 fiords from the sea at Morecambe Bay into the neighbouring hilly 

 countr3^ The lacustrine peat moors exhibit a succession of Vegetation 

 from open water associations to the Molinia swamp, and these are 

 grouped as Swamp Moors („Flach-moor"); in course of time peat is 

 formed and Sphagnum, Eriophonini , Calluna and Erica become 

 dominant, these the author groups as Heath Moors („Hochmoor"), 

 and in time they may become Birch wood. The littoral peat moors 

 are a distinct feature of this part of England, and the Vegetation 

 Shows relationship with the Fen district of eastern England. The 

 first Vegetation grew on silt under water, and in time became 

 swamp moor, to be followed later by heath moors; these phases
