Canarium sibulanense Elm. n. sp. 
Strict tree; stem 10 m. high, 2 dm. thick; branches 
mainly toward the top and forming a rather dense crown; 
twigs brownish and with suberect tips; wood odorless and 
tasteless, reddish brown toward the center, moderately hard; 
old bark checked in small plates, that on the branches smooth 
and yellowish gray. Leaves 5 dm. long, ascending, im- 
paripinnate; rachis finely puberulent along the upper side, 
with 5 to 7 pairs of leaflets; leaflets nearly flat, mostly 
descending, only the acute to acuminate tips recurved, sub- 
lucid on both sides, chartaceous, drying dull green, elongate 
oblong or ovately elongated, the basal pair much smaller, 
the terminal one largest and symmetric at the base, the 
lateral ones obtusely rounded and inequilateral at the base, 
‘margins entire, the largest ones nearly 2 dm. long, 3 cm. wide 
across the middle or toward the base, glabrous except the 
nerves beneath; midrib conspicuous beneath, brown, sparsely 
hairy; lateral nerves 13 to 23 on each side, oblique, rela- 
tively prominent, their tips interarched, reticulations coarse 
but quite evident, all more or less sparsely puberulent; pe- 
tiolule 0.75 em. long, terminal one 3 em. long, ends somewhat 
thiekened and in the young state ferruginous pubescent; stip- 
ule densely ferruginous, usually 3-forked from the base, the 
middle of the rather rigid setaceous segments 2 cm. long, 
the divergent lateral ones scarcely more than one half as 
long. Inflorescence from 2,5 dm. to nearly 6 dm. long, dense- 
ly covered with a ferruginous pulverulence, interspersed with 
lighter colored hairs, ascending, axillary, panieulately branched 
from near the base, the secondary stalks very short, the 
larger branches subtended by stipular-like bracts, the upper 
ones very much reduced; flowers erect, few-clustered at the 
ends of the very short stalks, sessile, subtended by short 
triangularly acute bracts; calyx thick, green and covered with 
the same puberulence but usually mixed with more hairs, ap- 
pressed canescent on the inner side, 5 mm. long or longer,
