 8 mm. long, 6 mm. across. 



Type specimen No. 5863 (A. D. E. Elmer), Baguio, Province of Benguet, 

 Luzon, March, 1904 (flower) ; also No. 128 (D. L. Topping), same locality, 

 February, 190.3 (fruit); No. 3876 (Merrill), Mount Arayat, Province of 

 Bataan, Luzon, August, 1904 (fruit). No. 3836 (Merrill), Mount Mari- 

 veles. Province of Bataan, Luzon, May, 1904, is closely related if not 

 identical. 



This species grows in Benguet in tliickets along streams in the pine 

 region at an elevation of about 1,700 m. above the sea, and on Mount 

 ^lariveles and Mount Arayat on exposed wind-swept ridges near the 

 summit of the mountain in each case. It is apparently related to 

 Pitliecolohium suba(nittim Benth., and P. montanum Benth., difi'ering from 

 both especially in its very small leaflets.
