R. lussoniense Rendle in Journ. Bot. 34 (1896) 356; Merr. 1. c., 43. 
Luzon, Province of Cagayan, Caua Volcano, R. N. Clark s. n., altitude 930 m:

Elmer 71/75 ; Mount Malaraya, For. Bur. 7839 Curran dc Merritt, altitude 1,000 m. 
A shrub, usually of small size and epiphytic, the flowers white. The type of 
the species was from the District of Bontoc, while the type of R. lussoniense 
Rendle, in Herb. Mus. Brit., is labeled Bagnen, Mount Polis, which is also in the 
same district. The species is somewhat variable in the form of its leaves. 
10. R. mindanaense Merr. in Govt. Lab. Publ. (Philip.) 29 (1905) 41. 
Mindanao, District of Davao, Mount Apo, Copeland 101/2 ; DeVore & Hoover 73, 
altitude about 3,000 m. 
A species known only from Mount Apo. 
11. R. copelandi Merr. in Govt. Lab. Publ. 29 (Philip.) (1905) 42.

12. R. curranii Merr. in Philip. Journ. Sci. 3 (1908) Bot. 255. 
Luzon, Province of Zambales, Mount Tapulao, For. Bur. 8061 Curran & 
Merritt; Bur. Sci. 1/988 Ramos, December, 1907, altitude 2,000 m. 
A species allied more closely to R. whiteheadii Rendle, than to R. lussoniense 
Rendle, but with longer and relatively narrower, quite differently shaped leaves. 
Additional material may prove the two species too closely allied to be kept 
separate. 
13. R. whiteheadii Rendle in Journ. Bot. 34 (1896) 356; Merr. 1. c. 43. 
Luzon, District of Bontoc, Mount Polis, Whitehead, in Herb. Mus. Brit. 
I have seen only the type of this species, which is from Mount Polis, according 
to the label. 
14. R. mal indangense Merr. in Philip. Journ. Sci. 3 (1908) Bot. 256. 
Mindanao, Province of Misamis, Mount Malindang, For. Bur. 1/705 Mearns & 
Hutchinson, May, 1906, altitude about 1,800 m. 
In the original description of this species the leaves are erroneously described 
as oblong-ovate, which should be corrected to oblong-obovate.
