EBENACEiE. 



112. [Maba elegans, n. sp. 



A small slender tree about lo feet tall, with drooping 

 branches covered with rather long stiff hairs. Leaves alternate, 

 elliptic-lanceolate, obtuse, narrowed at the base, above 

 glabrous, smooth, beneath the midrib covered with long hairs, 

 nerves invisible, ^ inch long, ^ inch wide, nearly sessile, with 

 *a very small petiole. Flowers solitary, sessile or nearly so, on 

 the underside of the branches entirely silky hairy, \ inch long. 

 Sepals 4, ovate-rounded ; tube of corolla elongate bottle-shaped, 

 narrowed upwards; lobes lanceolate-obtuse, 3, hairy outside, 

 glabrous inside. Pistil club-shaped, hairy, shorter than the 

 tube of the calyx. Styles short, thick, glabrous; stigmas 

 subtriangular, toothed, white. Disc hairy. Staminodes fili- 

 form, 3, slender, shorter than the pistil. Male flowers not seen. 



Kuala Teku woods behind the Camp. 



Apparently allied to M. Beccarii, Hiern, of Borneo. 

 Altogether the smallest Ebony-tree I know, not much more 

 than a shrub, and with very small leaves and flowers.] 



APOCYNACE^. 



113. Alyxia angustifolia, n. sp. 



Usually a slender climber in woods, suberect on the open 

 Padang. Stems dark brown. Leaves coriaceous, elliptic- 

 lanceolate, blunt or subacute, glabrous, margin thickened, 

 midrib on the back very thick, channelled above, nerves 

 invisible on both surfaces, i to 2 inches long, \ inch wide, in 

 pairs or whorls of 3; petiole | inch long. Flowers in terminal 

 or axillary cymes, half an inch long, about 12 in a cyme; 

 peduncle and pedicels short, scurfy, pubescent, ribbed. Sepals 

 linear or lanceolate-linear, ^^ inch long, pubescent. Corolla 

 white, \ inch long, glabrous; tube slender, cylindric, dilated 

 slightly just below the lobes; lobes short-ovate, obtuse; mouth 

 of tube with a thickened ring inside, below white hairy. 

 Stamens 5; filaments very short; anthers tapering upwards, 

 lanceolate. Style not longer than the anthers, glabrous. 

 Stigma clubbed. Ovary white, villous. Fruit black, elliptic- 

 obovoid, \ inch long. 



Very common on the Padang, and in the woods, one of 

 the very few climbers there. 



Allied to A pmnila, Hook fil., of Mount Ophir and other 

 parts of the Peninsula, but with very narrow stiffly coriaceous 

 leaves with invisible veins.
