THE COUPE BOTANJQUE HES ALPES 
Abbreviated from a Report made bj' Miss M. S. Campbell to the 
Council of the Society. 
In August 1950 I attended, as the Society’s official representative, 
the CoLiim Botanique des Alpes, the 78th Session Extraordinaire of the 
Societe Botanique de France. 
This remarkable excursion, which may be described as an ai)])endix 
to the International Congress at Stockholm, was organised with the 
co-operation of the Societe Botanique Suisse and Austrian botanists. 
Its object was to review the princi])al biological and biogeographical 
problems raised by the Flora of the Alps and the solutions arriA'ed at 
by the leading si)ecialisks on the subject. We were able to follow, with- 
out being encumbered with too much detail, the transformation of the 
alpine Flora from east to rvest and the ecological contrasts produced by 
different rock formations and exposures, and rvere given a fine impres- 
sion of the vegetation of 'the great massif around which is grouped the 
European Flora. 
An admirable guide for the excursion was issued to all participants, 
the quality of which is best summed up by a list of the contributors, 
all of whom were Avith us in the field:- — Prof. H. Gams (Innsbruck), 
Dr. E. Schmid (Zurich), Dr. "W. Liidi (Zurich), Dr. W. Rytz (Berne), 
O. Hirschmann (Saas Fee), Prof. F. Chodat (Geneva), Dr. P. Guinier 
(Paris), Dr. B. de Vilmorin. C. Guinet, Prof. Humbert (Paris), Dr. 
Becherer (Geneva) and Prof. Braun-Blanquet (Montpellier). Among 
the official representatiA*es Avere : — Dr. Rousseau and Prof. Prat from
