Bruce Roberts was re-elec- ted Chairman and Suzanne Warwick Secretary. The executive agreed to prepare a brief summary of current ecological activities in Canada for the CBA/ABC Bulletin, similar to that prepared by the THOMAS M.C. TAYLOR Systematics Phytogeography Section. Symposium topics for the Fredericton meeting were discussed. I received notification of a new publication General Section by Dr. Thomas M.C.
