former is ''To-tot-tot" the latter “Tolling” in the Bagobo

On account of several very important characters it does 
not belong here and it may represent a new genus. 
ALSTONIA R. Br. 
Alstonia iwahigensis Elm. n. sp. 
A middle sized tree; stem 6 dm. thick, strongly wadded 
toward the base, otherwise terete and nearly straight, 12 m. 
high at least; wood very light and soft, white and with a yellow- 
ish tinge or more yellow toward the center, odorless and with 
a slight bitter taste; bark dull brown and gray mixed, minutely 
checked, the middle portion yellowish brown, the inner side sappy 
White, eontaining on abundance of latex; main branches at the 
top, spreading and forming a flat crown, ultimately numerously 
rebranched; the branchlets subverticellate, soft, green, easily 
breaking, glabrous, the young portion wrinkled in the dry state. 
Leaves rotately spreading, similarly disposed, profuse, coria- 
ceous, eonduplicate on the upper shining deep green surface, 
glaucug green beneath, drying characteristically grayish or 
dull caesius, quite variable in size, gradually tapering to the 
obtusely rounded apex, base bluntly obtuse, the larger lamina 
8 em. long and 3 em. wide across the middle, oblong, the entire 
margins slightly recurved or straight, glabrous; midvein raised 
beneath, sunken above; lateral nerves equally evident from 
both sides at least in the dry leaves, at right angles to the mid- 
vein, their tips distinetly united just under the margin, 25 to 30 
pairs, reticulations none; petiole 1 to 1.5 cm. long, also glabrous 
expanded by the narrow continuation of the basal leaf portion. 
Inflorescence erect, always terminal; the 3 to 5 peduncles strict, 
green, 5 to 8 em. long, somewhat angular or compressed, glabrous, 
or very finely puberulent toward the top, 1 to 3, verticellately 
branced from above the middle; the second branching 2 to 3 em. 
above the first, the ultimate one short; flowers umbellately group- 
ed at the ends of very short thick stalks which are themselves ver- 
ticellately arranged, numerously subtended by pubescent bracts, 
the 3mm. long pedicels densely olivaceus tomentose; calyx 3 mm.
