mately separating clear to the base; stamens as many, deeply

This pretty species forms dense masses on very moist 
humus covered soil, or encirling small tree trunks a few feet 
from the ground in a deep forested oak basin at 3750 feet, 
south of the Baruring river. The Bagobos call it ''Rader^ 
and ''Piadar." This same species seems to extend through 
Negros to Luzon. 
Elatostema integrifolium Wedd. 
Dense thickets, 1 to 2m. high; stem suffrutescent, with 
slender fibrous roots, soft, green, the thickness of an or- 
dinary lead pencil, reclining toward the base and branched 
from near it, more numerously branched above the middle; 
branches covered with minute cystoliths, the apical portion 
yellowish brown strigose, widely and laxly spreading. Leaves 
alternatingly scattered along all the more or less numerous 
branchlets, nearly equally sided and straight, thinly coriaceous, 
dark green except the paler underside, divaricately spreading 
on a horizontal plane, flat or the caudate tips only slightly 
recurved, dull green when dry, densely covered with cystoliths 
on both sides, glabrous except the nerves beneath, the larger 
ones 1 dm. long, nearly 2 cm. wide across the middle, oblong-
