Phalacnopsix aphrodite JJoiclib. f., Diclisonia smithii Hook., DaralUa 

 cumingn Hook., and Poli/podiuni tiwijcnUinuin Schott. This list of but 

 20 species is verv small Avlien compared with the list of over 50 known 

 exclusively from Celebes and the Philippines,^ the Celebes-Philippine 

 list including two genera confined to the two gi-oups, Walhiccodcndron, 

 monotypic. and Reinirardtiodendrou. two species; moreover the flora of 

 Formosa is infinitely better known than is that of Celebes. Three 

 species, Boea swinlioii Hanee, MoUotus playfairii Hemsl., and Gdulthrria 

 horncensis Stapf, have the peculiar distrilmtion of from Formosa to 

 Luzon and noi-thern Borneo. 



A certain number of species extend from Japan to southern China, 

 Formosa and Lvizon, and another group, Himalayan types, extends from 

 the Himalayan region eastward to the mountains of Formosa and Luzon, 

 and sometimes to Japan, but these can not be considered as throwing 

 much light on the individiuil relationships of the floras of Luzon and 

 Formosa, as, at least the Himalayan types, might have reached tlie two 

 islands independently, and at entirely different periods. 



The collections adds to our knowledge of the Philippine flora two 

 genei-a, Erythraea. represented by the introduced E. spicata (L. ) l^ers., 

 and Phoenix, represented by a new variety of P. hanceana Xaud., and
