oil dots are small but very numerous. Inflorescences 1- or 2- 
flowered, axillary, pedicels slender with a few minute bracts. 
The flower buds are very large, 35 to 45 by 10 to 12 mm, greenish- 
white. The petals are 35 to 40 by 5 to 10 mm, bluntly pointed 
at the apex and narrowed gradually to the base. Stamens 10, 
unequal, filaments long, slender, free. Pistil 20 to 25 mm long, 
slightly hairy, with a clavate ovary narrowing abruptly into 
the cylindric style 12 to 15 mm long, which ends in a capitate 
stigma. Ovary 5- or 6-celled, narrowing gradually toward the 
base. Fresh fruits subglobose, when dry often slightly oval, 
70 to 80 mm in diameter, nearly smooth, gray-green with a 
leathery pericarp 10 to 12 mm thick with irregular branched 
lacunae filled with a resinous gum; loculae 5 or 6, with carti- 
laginous solid walls 3 to 4 mm thick, the locules filled with a 
transparent jellylike gum surrounding the seeds. Seeds 8 to 
10 in a locule, lenticular, 9 to 10 by 7 to 8 by 3.5 to 4 mm, 
gray-green in color, abundantly provided with very thin, elon- 
gated, hairlike, slightly fimbriate paleae 6 to 10 mm long, 0.26 
to 2 mm wide. Near the hilum on the angle of the seed is a 
light yellowish-gray ariloid ridge 5 to 7 mm long and 1 to 2 
mm high; because of the numerous hairlike fimbriate paleae 
the seeds almost completely fill the space, the interstices alone 
being filled with transparent jellylike gum. In the fresh fruits 
the paleae of the seeds being embedded in the transparent gum 
are very inconspicuous, but become increasingly conspicuous as 
the fruit dries. 
On germination the cotyledons remain buried, the first pair 
of foliage leaves are opposite, entire, broadly lanceolate, the 
next few foliage leaves are pinnate with more and more leaflets. 
The leaflets often have sharply serrate margins. 
The specimens studied at Manila, collected in March, 1918, 
as well as the fruits sent to Washington and the seeds planted 
at Los Banos, all come from a tree in the Singapore Botanic 
Gardens. It is probable that it was grown from seeds taken 
from the fruit sent to the former director, H. N. Ridley, “some 
years” before 1908, collected by F. G. Penney in southern Siam, 
especially as Ridley states in his original description of the 
species that he then had seedlings in the botanic garden. If 
planted, say in 1904, the tree would have been old enough to 
bear fruit in 1917 when Professor Baker collected fruits. 
POSSIBLE ECONOMIC USES OF THE KATINGA 
If the katinga proves to be rather closely related to Chaeto- 
spermum it is not improbable that, like Chaetospermum gluti-
