NEW OR INTERESTING PHILIPPINE VITACEAE 
By E: D. Merrill * 
( From the Botanical Section of the Biological Laboratory, 
Bureau of Science, Manila, P. I.) 
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.
