 between the seeds on the lower margin. Seeds 5 to 10, ovoid, compressed, 

 8 mm. long, 6 mm. across. 



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

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

 February, 1903 (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 thickets along streams in the pine 

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

 Mariveles and Mount Arayat on exposed wind-swept ridges near the 

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

 Pithecolo'blum subacutum Benth., and P. montanum Benth., differing from 

 both especially in its very small leaflets.

 subglobose inflorescence. Flowers 2.5 to 3 cm. long, their pedicels slender, 

 glabrous, about 3 cm. long. Calyx tubular, slightly inflated, 6 to 9 mm. 

 long, 5 to 6 mm. wide, glabrous, the teeth very short, rounded, the bracts, if

 corolla light azure blue. Stem about 2.5 cm. in diameter, soft and ropelike,
