elliptic-lanceolate, sub-acute, the base narrowed into the petiole ; upper 

 surface shining ; lower dull, sub-glaucous ; nerves 8 to 10 pairs, not pro- 

 minent, reticulations minute ; length 3 to 4 in., breadth 1 in. to 1'4 in. ; 

 petiole rather thick, less than *25 in. Flowers -25 in. long, otherwise as 

 in X. Griffithii. Fruit globose when quite ripe, slightly warted, and 1 

 in. in diam. Hook. fil. Fl. Br. Ind. I, 209 ; Hassk. in. Miq. Ann. Mus.

This differs from X. Griffithii chiefly by having many more nerves 

 in its leaves. 



5. Xanthophtllum Palembanicum, Miq. Ann. Mus. Lugd. Bat. I, 

 317. A glabrous tree 30 to 40 feet high ; branchlets slender, pale. 

 Leaves membranous, drying pale green, lanceolate, rarely elliptic, caudate- 

 acuminate, the base narrowed ; acute or cuneate ; upper surface shining, 

 the lower dull, pale but not glaucous, main nerves 4 to 5 pairs, slightly 

 prominent, reticulations minute ; length 3 to 4*5 in., breadth 1*1 to 1*3 

 in. ; petiole "2 in., slender. Flowers '4 in. Bacemes axillary, few- 

 flowered, slender, shorter than the leaves. Sepals unequal, rhomboid, 

 spreading, flat, puberulous externally. Petals spathulate, glabrous except 

 the pubescent keel. Filameyits thickened and pubescent in the lower 

 half. Ovary shortly stipitate, villous ; the annular disc surrounding it 

 small ; style sparsely villous. Ovules 4, from near base of ovary. Fruit 

 globose, '75 in. in diam., glabrous, boldly verrucose and with several 

 irregular vertical grooves ; pericarp "l in. thick, crustaceous. 



Perak, rather common. Distrib. Sumatra. 



This is not unlike X. Maingayij but is at once distinguished from 

 that by its deeply grooved fruit. 



6. Xanthophtllum eurhtnchum, Miq, Ann. Mus. Lugd. Bat. I, 

 277. A glabrous tree 30 to 60 feet high ; branchlets terete, brown. 

 Leaves drying pale green, sub-coriaceous, elliptic-lanceolate tapering at 

 both ends, to elliptic with rounded base and apex shortly acuminate ; 

 both surfaces smooth, the upper shining, the lower dull slightly paler ; main 

 nerves 4 to 5 pairs, prominent beneath ; length 4 to 5-5 in., breadth 1-75 

 to 2-5 in., petiole '3 in. Flowers '25 in. long, the pedicels not longer 

 than the calyx. Bacemes shorter than the leaves, pubescent, axillary 

 and solitary or in terminal few-branched panicles. Sepals unequal, ovate- 

 oblong, blunt, spreading, minutely tomentose externally. Petals spathu- 

 late, glabrous except the pubescent keel. Filaments slightly flattened 

 and pubescent in the lower half. Ovary villous, 4-ovuled. Style slight- 

 ly curved, villous. Fruit globose, -75 in. in diam., puberulous, rather 

 minutely verrucose, not vertically ridged ; pericarp crustaceous, brittle, 

 '2 in. thick.
