Reports on the luternational Congress of Bolanists, 

 held at Brussels in May 1910. 



[Presented 15th December, 1910.] 



Dr. O. Stapp introduced his report on the International Botanical 

 Congress, held at Brussels between May 14-22 of the present 

 year, with a short account of the working programme of the 

 Congress as it arose out of the decisions of the last International 

 Botanical Congress which met at Vienna in 1905 and the disposi- 

 tions of the Belgian Bureau. There were altogether 5 sections. 

 Sections I. and II. were charged with the discussion and codifica- 

 tion of the special arrangements necessary with respect to the 

 nomenclature of fossil and non-vascular plants on account of 

 their special nature. Tacked on to them were two propositions 

 dealing with an extension of the list of ' nomina conservanda ' 

 for phanerogams and vascular cryptogams, adopted at Vienna. 

 Section III. was reserved to ' phytogeographical nomenclature.' 

 Section IV. was to deal with bibliography and botanical documen- 

 tation, and Section V. with botanical instruction. Sections I. 

 and II. continued the work of the Vienna Congress in so far as it 

 concerned nomenclature. Section III. was the result of the 

 deliberations of a new Commission appointed by the Vienna 

 Congress. The other two sections were added by the; Belgian 

 Bureau. 



The Liunean Society appointed five delegates for the Congress 

 with a view to have the different departments concerned in the 

 discussion on taxonomic nomenclature as far as possible repre- 

 sented. The delegates were Messrs. Arber (fossil plants). Cotton 

 (Alg?e, Licliens, and Fungi), Gepp (Musci and Ifepaticse), Henry 

 Groves and Dr. Stapf (Phanerogams and Vascular Cryptogams,
