Christmas Island Flora— Additional 

 Notes. 



By H. N. Ridley. 



Tristiriopsis nativitatis, Hemsl. 



Mr. Hemsley has since the publication of this report 

 given a figure of this plant from specimens collected by 

 me in the Icones Plantarum No. 2812, as Tristiropsis 

 Ridleyi order Sapindaceae tribe Melicocceae. He says 

 it almost certainly belongs to the same species as a 

 specimen collected by Lister in 1887, but the leaves 

 and leaflets of that were twice the size, and Lister notes 

 the tree is 100 feet high and 13 feet through. I never 

 saw one nearly as large as this, in the island. Flowers 

 are much wanted of this. 



Dendrobium pectinatum, Ridl. 



I find that this name is already occupied by another 

 species, so the name must be changed to D. nativitatis. 

 Dr. Christ has examined some of the ferns T sent him 

 which were somewhat doubtful and gives the following 

 identifications. 



Asplerium paradoxum^ Bl. 



One specimen I got in Christmas Island proves 

 to belong to this species. It is very doubtful how- 

 ever how far this can be kept distinct from A. 

 macrophylhim. 



Pleocnemia gigantea, Hook. 



Common in the Plateau, Phosphate Hill and Flying 

 Fish cave. An addition to the Flora.
