134 The Philippine Journal of Science wig 



This species has previously been reported only from. Hongkong and 

 southern China, and most of the specimens cited above have here been 

 determined as Cissus japonica Willd. In fact Gagnepain, conforming 

 with this identification, recently cited Whitford 23, fruiting specimen only, 

 under Willdenow's species. An examination of the material in all stages, 

 however, shows that the petals are very prominently corniculate, and 

 the anthers are not longer than broad, so that the material cannot be 

 referred to Cissus japonica. In all essential characters the Philippine 

 specimens appear to agree with Cissus corniculata Planch., and with a 

 single Hongkong specimen, Hongkong Bot. Gard. 1982, April 22, 1904, in 

 the herbarium of the Bureau of Science. This latter specimen has some- 

 what narrower, differently shaped, and fewer-nerved leaflets than has the 

 Philippine material, and comparison of a full series of specimens may show 

 sufficiently constant characters to warrant the later separation of the 

 Philippine plant as a distinct species. At any rate our material cited 

 above represents a form as distinct from Cissus japonica Willd., as is 

 the Hongkong (typical) Cissus corniculata Planch.

The specimens cited above previously have been referred to Cissus 

 japonica Willd., but following Gagnepain's recent arrangement of the 

 species of Cayratia they can hardly represent Willdenow's species, as the 

 anthers are orbicular or suborbicular. The Philippine specimens cited 

 above certainly represent the same species as Gallery 93, and Bodinier 

 2290, in our herbarium, both cited by Gagnepain under Cayratia tenuifolia 

 Gagnep.

I have seen no Philippine material that I consider to be referable to 

 Cayratia japonica (Willd.) Gagnep. In the present paper most of the 

 specimens previously so named are referred to Columella corniculata 

 (Benth.) Merr., and the remaining material to the present species.

 This species is common and widely distributed in the Philippines, being 

 found throughout the Archipelago at low altitudes in the settled areas. 

 India to China and southward to tropical Australia.
