and alpine, elements are more or less numerously represented 

 in this flora. Elements of Tropical America, North America, 

 the Himalayas, and Malay, are shown under special headings. 

 As the elements of central and southern China and those of 

 Japan are most numerously represented in this flora, the writer 

 has especially called his attention to the comparison of the floras 

 of these three regions, i.e. Japan, Formosa and China. He has 

 here mentioned 9 species peculiar to Formosa and China, w^hich 

 are Hoeckia Aschersoniana Engl, et Gr/Ebn., Senecio monanthus 

 DiELS, Petasites tricholobus Franch., Gentiana humilis Stey., 

 Salvia scapiformis Hance, Daphne Championi Benth., Liboce- 

 drus macrolepjs Benth., Pinus Armandi Franch. and Keteleeria 

 Davidiana Beissn. Two genera, Hoeckia and Keteleeria are 

 found in Formosa and China, but nowhere else. He has also 

 pointed out that there are 16 species which are known to 

 exist only in Formosa and Japan. They are Clematis lasiandra 

 Maxim., Mitella japonica Miq., Trochodendron aralioides S. et 

 Z., Fatsia, Galium hrachypodium Maxim., Lysimachia sikokiana 

 MiQ., Conandron ramondioides S. et Z., Tsuga diversifolia 

 Maxim., Pseudotsuga japonica Shirasawa, Abies Mariesii Mas- 

 ters., Chamsecyparis pisifera S. et Z. (represented by C formo- 

 sensis Matsum,), Chamaecypaiis obtusa S. et Z., Pinus parviHora 

 S. et Z. (represented by P. formosana Hayata), Metanarthesium 

 foliatum yiAXiM., Juncus Maximowiczii Fr. et Say. and Plagio- 

 gyria Matsumureana Making. He has also mentioned that 

 there are 4 genera peculiar to Japan and Formosa. They are 

 Trochodendron, Fatsia, Conandron and Metanarthesium. The 

 Japanese elements are, on the whole, a little less numerously 

 represented in the Formosan flora than the elements of China, 

 so far as the figures of the elements are concerned. The 

 author, however, has emphatically stated that the number 

 of the plants peculiar to both islands far exceeds the 

 number of those which are confined to the continent and 

 Formosa. Endemic plants are, he says, comparatively nume- 

 rous as is to be expected in an island. Among the plants 

 treated in this work, the most striking species, with endemic 

 genus, Taiwania, are as follows: — Fatsia polycarpa Hay.,
