17,6 Merrill: Studies on Philippine Rubiaceae, IV 469 
While the present species does not present any remarkably 
distinctive vegetative characters, its flowers are unusually small 
and slender for the genus. It does not appear to be very closely 
allied to any other described form. : 
To this species I also refer the following specimens, which 
were mostly identified by Mr. Elmer with Stylocoryne macro- 
phylla Bartl.: LUZON, Bataan Province, Mount Mariveles, Whit-

This species is of very wide distribution in the Philippines, 
and is somewhat anomalous in Tarenna in the reduction in the 
number of ovules. In most cases there appear to be but one or 
two ovules in a cell; but some of the Philippine material, that 
I cannot otherwise distinguish, presents fruits with as many 
as five seeds. The usual number of seeds is apparently two in 
each fruit. I am by no means convinced that Tarenna incerta 
Koord. & Val: is the oldest valid specific name for this species, 
but feel certain that the Philippine synonyms are properly placed 
under it. I have a specimen from Burma, Prazer 79, that is 
a close match for Koorders 39255, 39260, 6770, from Java, of 
which I have specimens before me. I refer here the following
