DECEMBER 15, 1910] URTICACEAE FROM THE Vicinity oF Mr. Aro 899 
the fine branchlets, diverse in size, copious, membranous, 
flat, the roughened sparsely strigulose upper surface light green, 
beneath much paler and soft tomentose, most of them de- 
scending, ovately oblong to broadly lanceolate, the larger blades 
8 em. long by 2.5 em. wide across the middle or just a 
trifle below it, apex gradually tapering into the acute or acu- 
minate point which is usually falcate, base obtusely rounded, 
serrately dentate except the entire basal portion, the lower side 
turning olivaceous brown and the upper nearly black when dry; 
midvein quite prominent beneath, densely subolivaceous pu- 
bescent, with 3 to 5 lateral pairs; the basal pair strict and 
extending two thirds up the blade, the other ones ascendingly 
arched, reticulations fine and quite conspicuous, all similarly hairy 
petiole 0.75 to 1.5 em. long, pubescent; stipule free, 7.5 mm. 
long, the sides hyaline and brown, deciduous, only the medium 
dorsal line and the basal portion strigulose, lanceolate, with 
a sharp point. Pistillate flowers and fruits mainly clustered 
in the fallen leaf axils along the branchlets; flowers upon pseu- 
dostalks, solitary or 2 to 3-clustered; the basal subtending bracts 
quite broad, less than 1 mm. in length, finely ciliate along 
the margin and on the exposed dorsal side especially along 
the median line; the inner ones smaller, narrower, less cil- 
iate; perianth 0.5 mm. long minutely 3-toothed, subglabrous 
or very finely ciliate especially toward the top; stigma pu- 
berulent, 1 mm. long, longer in the fruit, recurved at the 
tip, articulate at the base and sublaterally attached, pale white 
in the fresh state, dark brown when dry; fruit 1.5 mm. long, 
obliquely obovoid, 1 mm. thick above the middle, pointed 
toward the base; the pubescent perianth easily separating from 
the slightly compressed achene.

the vernacular Bagobo name.
