Through publication of monographs, and other activities , the Society tries to stimulate geobotanical research and its appli
cation to practical and scientific problems . Membership is open to all who have a personal interest in the advancement of phytogeography .
Individual members and subscribers ( societies, institutes, libraries, etc . ) receive the A cta Phytogeographica Suecica for annual dues of 50 Skr plus postage . There are additional fees in years when more than one volume are i ssued. For member
ship please apply to the Secretary .
