The following- description of Hydnocarpus hutchinsoniii is 

 quoted from Bureau of Science press bulletin No. 105, January 

 27, 1922: 



Found in the eastern part of Mindanao, on Basilan Island, in the Sulu 

 Archipelago, and in British North Borneo. The tree grows to a height 

 of 25 meters but is usually not over 15 meters in height. Most of the 

 trees have a diameter of 10 to 15 cm, one meter from the ground, but 

 the larger specimens attain a diameter of 35 cm. The bark is rather 

 smooth, often stippled. It is found in the primary forest, but the largest 

 specimens are found in the bog or cut-over forest. It is found from sea 

 level to at least 600 meters altitude. 



Leaves. — The leaves are oblong, smooth edged, 15 to 30 cm long, 5 to 12 

 cm wide, the base distinctly inequilateral, usually rounded or obtuse 

 on the broader side, and often acute on the narrower side, the apex rather 

 abruptly and distinctly pointed. The upper surface is dark green, shining, 

 smooth, the lower surface brownish, distinctly showing reticulated veins. 

 The lateral veins 12 to 14 on each side of the midrib, prominent, curved, 

 anastomosing close to the margin. Petioles usually about 1 cm long. 



Flowers. — Small, yellow flowers about 1 cm long. 



Fruits.— The tree fruits in July or August although a few fruits are 

 found at other times of the year. The fruit is almost spherical, from 

 7 to 10 cm in diameter, with a short stocky stem. The shell (pericarp) is 

 rather thin and brittle when dry, with a smooth surface. The fruit con- 

 tains from 20 to 45 seeds in a small amount of pulp. The fruit is a 

 light brownish green on the tree, turning to a brown when dried. The 

 appearance roughly resembles that of an orange. 



Seeds.— The seeds are packed tightly in the fruit and hence have a 

 rounded polygonal shape not over 2.5 cm long. When dried, part of the 

 seed is smooth with slight ridges, and part covered with tiny warts. The 

 shell of the seed is thin, brittle, and brown when ripe. The kernel is solid, 

 white, oily, odorless, and rather tasteless. 



Local names.— The tree is known by the people of various districts as 

 follows: Basilan — mansaloka, mangasalokag ; Zamboanga Peninsula — ka- 

 mupang, dinagas, tioto, sugalingayan; Lanao — bagarbas, kalumpang; Jolo — 

 kaumpang, kamupang. 



Collection of fruit.— The fruit falls about July or August and should 

 be collected at that time, and the seeds removed and dried immediately 

 to prevent molding. 



Dr. H. I. Cole, of the Bureau of Science, in a recent extensive 

 survey found a large supply of these seeds in Mindanao forests, 

 but the difficulty in collecting them and the relatively high price 

 of Moro labor have prevented us from obtaining a regular 

 supply. The samples used in this study were collected at Ba- 

 silan, Zamboanga, by Doctor Cole with the cooperation of the 

 Bureau of Forestry.
