臺灣南部之植物

Phytogeographical Affinities of Southern Taiwan

The phytogeographical relations between Taiwan or Formosa and the Philippines have been discussed in an illuminating essay by Professor Merrill (25). In that he emphasizes the great differences between the two floras in spite of their geographical proximity. Subsequently, the interesting fauna and flora of two small islands, Ho-shao-tao (Kasyoto) and Botel Tobago or Hung-tou-yu (Kotosho), which lie in the Pacific southeast of Taiwan, are made known by several Japanese biologists, such as Kano (14, 15, 16), Sasaki (31), and Kane hira (12). Their general similarities to the southern, rather than to the Taiwan fauna and flora have lead the first named author to propose extending the Neo-Wallace or Merrill and Dickerson’s Line northward to pass between the main island of Taiwan and these two small islands.
