the median dorsal line, oblongish lanceolate, terminating 
into a slender point, deciduous. Flowers and fruits in 
dense glomerules less than 1 cm. across, usually encir: 
cling the branchlets at the fallen leaf axils; involucral 
bracts irregular, glabrous, brown, rather thin, 1.5 mm. long; 
floral bracts numerous, hyaline, narrower and slightly shorter, 
also glabrous; pedicel of staminate flowers nearly 2 mm. long, 
without hairs; perianth similar in vestiture, campanulate, a 
trifle shorter, lobed to the middle; segments 4, ovately triangular, 
the apical margins with a few fine hairs; stamens as many, 
opposite the segments; filaments 1.5 mm. long, glabrous, 
conspicuously flattened below the middle; anthers broadly 
elliptic, 0.75 mm. long, emarginate at both ends, basifixed; 
pistillate flowers upon short branched stalks densely bracteate; 
achenes obovoidly lenticulate, 0.5 mm. long, closely surrounded 
by the perigonia which terminate about the base of the stigmas 
into minute teeth, subglabrous or with only a few strigulose 
hairs at the neck; stigma persistent, strongly recurved above 
the middle, finely puberulent except the basal portion. 
Type specimen 11641, A. D. E. Elmer, Todaya (Mt. Apo), 
District of Davao, Mindanao, September, 1909. Also my number 
11587. : 
In very rich humid soil of dense woods at 4000 feet. 
The last cited number is not exactly as the type, and was 
associated with OC. microphyllus Elm. at 6000 feet along the 
Cati creek. The former the Bagobos call ‘‘Salabogan,’’ the 
latter ‘‘Rami-rami.’’ 
PIPTURUS Wedd. 
Pipturus succulentus Elm. n. sp. 
Scandent; stem terete, 5 cm. thick, numerously branched; 
twigs slender, lax, brown, curved and drooping, with sube- 
rect tips; wood soft, porous, watery, odorless and tasteless; 
bark brown, smoothish except the puberulent tips. Leaves 
dull brown in the dry state, alternatingly scattered along the 
branchlets, the upper side deep green and glabrous, paler beneath 
and with a very fine puberulence, linearly oblong to lanceolate, 
quite variable in size, flat except the recurved acute to acuminate 
tips, the longer blades 1 dm. in length, 2.5 em. wide across the
