NEW OR INTERESTING PHILIPPINE VITACEAE 



By E. D. Merrill * 



(From the Botanical Section of the Biological Laboratory, 



Bureau of Science, Manila, P. J.) 



In the present paper are included notes on various of the older 

 and better known species of Vitaceae, with descriptions of new 

 species in the genera Ampelocissus, Cissus, Columella (Cayratia) , 

 Tetrastigma, and Leea. Fourteen new species and a few new 

 varieties are described, while some new combinations are made. 

 The most radical change in proposed or accepted nomenclature is 

 the adoption of the generic name Columella of Lourerio, dating 

 from the year 1790, for those species placed by Planchon in Cissus 

 § Cayratia, but more recently by Doctor Gagnepain placed under 

 Cayratia as a valid genus. The adoption of Columella of Loure- 

 rio for this genus of Vitaceae will invalidate the genus Columel- 

 lia of Ruiz & Pavon which typifies the family Columelliaceae. 

 This action in restoring Lourerio's generic name is taken delib- 

 erately in order that the case may be brought to the attention 

 of botanists generally, and that at some later date perhaps 

 Cayratia may be included in the lists of nomina conservanda 

 supplementary to those already adopted by the Vienna and 

 Brussels Botanical Congresses.
