372 MERRILL. 



This is a critical species, tlie exact range of which outside of Celebes and tlie 

 rhilipi)ines is somewliat doubtful, but extending to Borneo, Malacca and Perak 

 according to King and (iainlilc i had previously identified the small congested 

 form from the sununit of Moiuit Apo with Blume's species, but an examination 

 of liis type in Herb. Leiden shows that the lax form, typified by Vaccinium 

 viifidorense Rendle. is closer to it. From the notes I made on the types of V. 

 mindorense and V. niicrophi/lluin. and from a reexamination of the Philii^pine 

 material I can not find any distinguishing characters, and accordingly have here 

 i-ediU'cd Rendle's species. On ]Moiuit Halcon, according to my own observations, 

 ami oil tlie Cuernos ISIountains 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 tlie 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 

 liigher altitudes in exposed situations and naturally having smaller and more 

 densely crowded leaves than has the epiphytic form, wliile the whole plant is 

 much congested. 



Diplycofiia inivrvpliijlhi Becc, was described by Beccari without any reference 

 to Vacciniiiiii microphylUnn Illume, 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 Diplycosia microphyUa Becc. is really the 

 same as Blume's species. L'nfortunately I have no specimens for c()m]>arison and 

 this question will have to be determined at a later date.
