ON THE FLORA OF BORNEO. 93 



short pale hairs. Leaves subcoriaceous, entire, oblong to 

 oblong-elliptic, 9 to 16 cm. long, 4 to 6 cm. wide, subequally 

 narrowed to the acute, scarcely glandular base and to the acute 

 or blunt apex; lateral nerves 8 to 10 on each side of the mid- 

 rib, prominent on both surfaces, curved, anastomosing, the 

 reticulations prominent; petioles 1.5 to 4 cm. long. Stamin- 

 ate inflorescences axillary, solitary, paniculate, up to 12 cm. 

 in length, glabrous or nearly so, branched from near the base, 

 the branches few, distant, spreading, the lower ones up to 4 

 cm. in length, the flowers white, cymosely disposed on the 

 branchlets, their pedicels up to 5 mm. long. Calyx about 4 

 mm. long, rather irregularly splitting into three oblong-ovate 

 lobes which extend nearly to the base, two of the lobes cleft at 

 the apex, somewhat contracted above and bearing two thin, 

 suborbicular lobules about 1 mm. in diameter, the third lobe 

 with a single terminal lobule. Petals 5, free, oblong-elliptic, 

 obtuse, entire, about 4.5 mm. long, rather densely villous with 

 pale hairs on the inner surface below. Disk glands prominent, 

 glabrous, up to 1 mm. in length. Stamens usually 7, their 

 filaments slightly united, pale-villous, up to two mm. in length. 

 Eudimentary ovary none. Pistillate flowers and fruits un- 

 known.

A characterises species apparently not closely allied to 

 any previously described form. It is somewhat anomalous in 

 the genus Ostodes in its few stamens, in this character aproach- 

 ing Ostodes minor, Muell.-Arg. The orbicular terminal ap- 

 pendages of the calyx lobes are characteristic, these correspond- 

 ing to the petals in number, arranged on the irregular lobes, 

 two lobes bearing two each, the third a single one.

 swamps at the mouth of the river; known to the Dyaks as 

 galctn. British North Borneo, Segalind Eiver, Foxworthy

The Bornean material perfectly matches Ridley 121/81 

 from Johore. The minute appressed teeth on the leaf-margins 

 are not mentioned by King in the original description of the 

 species.
