This is a critical species, the exact range of which outside of Celebes and the 
Philippines is somewhat doubtful, but extending to Borneo, Malacca and Perak 
according to King and Gamble. I had previously identified the small congested 
form from the summit of Mount Apo with Blume's species, but an examination 
of his type in Herb. Leiden shows that the lax form, typified by Vacciniuyn 
mindorense Rendle, is closer to it. From the notes I made on the types of V. 
mindorcnse and V. microphyllum, and from a reexamination of the Philippine 
material I can not find any distinguishing characters, and accordingly have here 
reduced Eendle's species. On Mount Halcon, according to my own observations, 
and on the Cuernos Mountains in Negros, according to Elmer, the species occurs 
both as an epiphyte and terrestrial, and I have both terrestrial and epiphytic 
forms from Mount Apo. At first sight the Apo epiphytic form appears to be 
very different from the terrestrial one, but careful examination shows no distin- 
guishing characters except vegetative ones, the terrestrial form occurring at 
r ^^ 
higher altitudes in exposed situations and naturally having smaller and more 
densely crowded leaves than has the epiphytic form, while the whole plant is 
much conj'ested. 
Diplycosia microphyJIa Becc, was described by Beccari without any reference 
to Vaccinium microphyllum Blume, but was considered by Hooker f. to represent 
Blume's species, in which he was followed by King and Gamble. It is possible 
that Hooker f. was correct and that Diphjcosxa microphylla Becc. is really the 
same as BIuuie*s species. Unfortunately I have no specimens for comparison and 
this question will have to be determined at a later date.

An erect terrestrial and epiphytic shrub 0.7 to 3 m high, in vegetative char- 
acters closely resembling the Bornean Vaccinium coriaceum Hook., but differing 
from that species in its axillary solitary flowers, Y. coriaceum having 8- to 10- 
flowered racemes.

The Mindoro specimen differs from the type in having a glabrous inflorescence, 
somewhat broader flowers and longer filaments which are prominently pilose. 
Additional material may prove it to be distinct.
