first collections, supplemented by material secured by other 

 collectors, brought the number of species up to about one thou- 

 sand twenty-five, while his second and more-extensive collections 

 have increased the list to approximately one thousand three 

 hundred seventy-five species, including the ferns and fern allies. 

 Future explorations will unquestionably greatly increase this list. 

 It is impracticable here to enumerate all the species now 

 known to occur in Hainan that are new to the Chinese flora. 

 The value of the collections, aside from the numerous new 

 species represented, may be estimated by the fact that one 

 family, Ochnaceae, has been added to the Chinese list, as well 

 as the following genera : Arthropteris, Scleroglossum, Mapania, 

 Arenga, Plagiostachys, Hedyosmum, Mitrephora, Polyosma, Elli- 

 panthus, Luvunga, Heynea, Azadirachta, Xanthophyllum, Cleis- 

 tanthus, Trewia, Ostodes, Gonocaryum, Arytera, Xerospermum, 

 Mischocarpus, Ochna, Taraktogenos, Decaspermum, Rhynchosia, 

 Epigynum, Kopsia, Fagraea, Rhynchotechum, Litosanthes, and 

 Erechtites. The genus Tsoongia of the Verbenaceae is described 

 as new. One of the most remarkable finds is a representative 

 of the genus Hedyosmum, of the Chloranthaceae, all other 

 representatives of the genus being confined to tropical .

Ng Chi Leng and Ka La to Ta Hon, McClure 9347 (type), 

 9213, April 20 and 21, 1922, on moist rock faces in ravines 

 and on forested slopes. Local name: Tsat ip yat chi fa. 



A species belonging in the group with Paris polyphylla Sm., 

 but, as variable as that species is, I do not see how the present 

 form can correctly be referred to it. The sepals and petals are 

 green, the stamens green and maroon, and the pistil is purple.
