1080 LEAFLETS OF PHILIPPINE BoTANY [Vor. III, Arr. 58 
yellowish, conspicuous, with 7 to 9-arched and united lateral 
pairs, reticulations coarse and faint beneath; petiole terete, 
brownish when old, thickened and expanded at the base; pet- 
iolule 1 to 1.5 em. long, the terminal one at least twice as 
long; stipule stout, 1 em. long, flattened, gradually tapering 
from the base to the acute apex, glabrous, attached 5 or more 
mm. from the base of the stalk. Inflorescence erect, mostly 
terminal; the stalk green, more or less flattened, glabrous, 
flower bearing toward the top, varying from 3 to 7 em. in 
length, always unbranched; flowers normally in small clus- 
ters of 3, rounded by rigid yellowish subglabrous and broadly 
rounded involucral bracts, upon 7 to 12 mm. long and divaricate 
stalks; sepals 3, free, rotund or orbicular, 4 mm. across, 
finely puberulent on both sides; petals of the same number, 
similarly puberulent on the outer exposed side, giving it & 
yellowish gray appearance, broadly oblong, 7 mm. long, 
obtusely rounded at apex; stamens 6, free; filaments gla- 
brous, equal, 2.5 mm. long, tapering from base to apex, 
inserted upon the outer basal portion of the thick rugose 
and pubescent sterile ovary; anthers basifixed, oblong, 1.75 
mm. long; fruits not seen. 
Type specimen 11007, A. D. E.' Elmer, Todaya (Mt. Apo), 
Distriet of Davao, Mindanao, June, 1909. 
This species was collected in damp though well drained 
soil of wooded ravines along the Baracatan creek at 1500 feet. 
The natives or Bagobos call it ''Ogat-biau-an."' 
From C. ovatum Engl. or Cuming 604 it can be recog- 
nized notably by the fewer leaflets with different apices, and 
in not having a fulvous rachis, peduncles and involucral 
bracts. It seems Dr. Perkins in Frag. Fl. Philip. page 94 
redescribed Engler’s species under C. pachyphyllum. Her mis- 
conception of what C. ovatum Engl. really was is shown 
when she referred 2472 Merrill under it. In the field it 
reminded one of a Meliaceous tree. 
Canarium costulatum Elm. n. sp. 
A rather small tree; stem 10 m. high, 2.5 dm. thick; 
branches few toward the top only, sparingly rebranched; 
the ultimate ones 2.5 cm. thick, suberect, ferruginous; wood
