1082 LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 58 
fruits of the other three species are similar in the hull 
which in the younger stage of devolopment is covered with 
brown somewhat stinging hairs and are 3-angled. The sides 
of Merrill’s species are plane, the ridges conspicuous and sim- 
ilarly curving from both ends. The sides of C. nervosum 
Elm. has a secondary ridge with 2 obscure lateral ones, and 
are deeply concave at the base, its main ridges are less 
pronounced and abruptly truncate at the base. The stone of 
C. costulatum Elm. is very different, not only from the species 
here discussed but also from all other Philippine species 
known to me except C. racemosum Merr., from which it differs 
in the leaves as well as in the character of the fruits. 
Canarium toncalingii Elm. n. sp. 
A medium-sized tree; stem 4.5 dm. thick, 15 m. high, terete 
but rather crooked, branched chiefly at the top; branches rigid, 
crookedly branched and widely spreading, the slender suberect 
twigs 2 cm. thick; wood rather tough and hard, whitish, 
without odor or taste; bark smooth, grayish white. Leaves 
clustered at the ends of the brown twigs, radially spreading, 
5 to 8 dm. long; leaflets 11 to 13, descending, very deep 
green and shining upon the upper slightly curved surface, 
chartaceous, lighter green beneath, the veins yellowish, drying 
dull green, oblong, the acute or acuminate tips recurved, 
base obtusely rounded, entire, 15 cm. long, nearly 5 cm. 
wide across the middle, the basal ones somewhat smaller; 
midrib conspicuous beneath and brown in the dry state, 
with about 17 lateral pairs whose tips are more or less 
united, the reticulations quite evident beneath; stipule seta- 
ceously acuminate, 8 mm. long, rufous puberulent but ulti- 
mately glabrous. Infrutescence axillary, varying up to 2.5 
dm. long, spicate or the larger ones few branched, ascend- 
ing, rufous brown, stout; nuts dark green, covered with a 
dirty yellowish gray pubescence, triangularly ellipsoid, equally 
tapering at both ends, at most 2.5 cm. long, 1.25 cm. 
thick across the middle, subtended by a thick persistent 
calyx 7 mm. across, upon short pedicels; flowers not seen.
