ing on the upper surface, only the short obtuse to acute tips 
recurved, glabrous, elliptic, base broadly obtuse, entire, the 
average blades 10 cm. long, 6.5 cm. wide across the middle, green- 
ish brown when dry; midvein very prominent beneath, straight 
from base to apex, smooth and glabrous; lateral nerves oblique, 
numerous, parallel, tips interarched and forming a conspicuous 
submarginal nerve from base to apex, similar to the nerves in 
Calophyllum, reticulations evident; petiole 2.5 em. long, also 
glabrous, deeply grooved along the upper side; bud bracts rigid, 
sharply acuminate, smooth, 1.5 em. long, one half as wide across 
the base, deciduous. 
Receptacles solitary or in pairs from the leaf axils, ellipsoid, 
2.5 cm. long, smooth, hard, yellowish when mature; peduncle 
very short, 5 &um. long, 3.5 mm. thick; bracts obsolete or occa- 
sionally present by a thick rim which usually does not encircle 
the base of the fruit; umbilicus minute, the inner bracts rather 
short and broad, smooth, light brown; flowers male and gall only 
or perhaps the intermixed young ones are fertile females; the 
male in a circle beneath the umbilical scales, 3.5 mm. long, sub- 
tended at the base by an involucre; stipe nearly 2 mm. long, 
brown, angular and curved, 1 mm. thick; basal bracts 3 to 5, 
unequal, also brown, glabrous, oblong to lanceolate; anther 1, 
subsessile upon the pedicel, 2-celled, 0.75 mm. long, a trifle 
narrower, closely enveloped by 3 rather rigid spoon shaped bract- 
eoles; gall flowers scattered, of diverse ages, very similar to the 
male flowers except that the basal bracts are thinner and nar- 
rower; gall ovary obliquely subglobose, 1.5 mm. across, smooth 
and shining, yellowish brown; style slender, 2 mm. long, similar in 
color, arising laterally, terminated by a flattened stigmatic portion. 
Type specimen 11921, A. D. E. Elmer, Todaya (Mt. Apo), 
District of Davao, Mindanao, October, 1909. 
Discovered on a steep densely wooded bench along the Sibulan 
river at 2500 feet altitude. The Bagobo name is “Marobutum.” 
Judging from both leaf character and fruits ours is most 
closely related to F. dubia Wall. and F. calophylla Blm. yet 
quite distinct from either.
