STUDIES ON PHILIPPINE RUBIACEAE, II 
By E. D. Merrill 1 
(From the Botanical Section of the Biological Laboratory , 
Bureau of Science, Manila, P. I.) 
The first paper of this series was published in the year 1913 2 
in which 35 new species were described with the addition of 
critical notes on previously described forms. The present paper 
is essentially similar to the first, consisting of critical notes 
especially in the genera Mycetia {Aclenosactne) , Chasalia, Psy- 
chotria, and Grumilea, with the descriptions of 42 new species 
in various genera. The genus Praravinia is new to the Philip- 
pines. The genus Coelospermum has been excluded from the 
Philippine flora by the reference of C. ahernianum Elm. to its 
proper genus, Psychotria. In connection with the recognition 
of Grumilea as a valid genus, it has been considered expedient 
briefly to enumerate all the Philippine species previously placed 
in the genus Psychotria, most of which are now transferred to 
Grumilea. The genus Psychotria, in the sense of Bentham and 
Hooker f., is a very large one in the Philippines, probably at 
least 90 distinct species being represented in the material already 
collected. In Psychotria, with the segregates Grumilea and 
Streblosa, 74 species are enumerated in the present paper, but 
a number of forms still remain to be described. As new forms 
are constantly being received as botanical exploration progresses 
many future additions are to be expected in this group.
