しだ植物の分布からみた台湾とフィリピン(<記念号>本岡武教授退官記念号)

Abstract

Pteridophytes in Taiwan and the Philippines are compared from a floristic point of view. The area of distribution for each species known in the two countries is considered, and the local florae are studied in detail for Orchid Island, Batan Island, and the Mt. Burnay area in northern Luzon. From these observations, a considerable disparity between the distribution of pteridophytes in Taiwan and Luzon emerges. Although pteridophytes do extend their area rather easily beyond the miles of discontinuity, their present distribution seems to have also been influenced by the geohistorical isolation of the areas concerned.
