This species comes very near to the Javanese P. bifida, Blume, but the latter 

 has narrower and longer leaves, with very many (20 to 25) pairs of main nerves and 

 many secondary ones with the intramarginal nerve much nearer the margin. The 

 peduncles and branches of the cyme and the pedicels are stouter and longer and the 

 corolla more fleshy. The anthers are similar, but the pollen-carrier appendicles are 

 more obliquely funnel-shaped (see t. xxii. in Bl. Mus. Bot. Lugd.-Bat. I.). The only 

 specimen in the Kew Herbarium is " Coll. T. Lobb, India 1868," and may be possibly 

 from the Peninsula. In the Calcutta Herbarium are specimens from Sumatra (H. U. 

 Forbes 2436). 



2. Pentanuea, Blume. 



Glabrous climbing shrubs. Leaves opposite, with nerves at right 

 angles to the midrib or nearly so. Flowers 1 to 3, on bracteate pedun- 

 culate racemose cymes in the axils of or opposite to one leaf of the pair. 

 Calyx small, 5 -fid, with 5 membranous scales alternate with the lobes 

 within. Corolla campanulate-rotate, fleshy, deeply 5-fid, papillose 

 within ; lobes oblong, concave, overlapping to the right. Corona none. 

 Stamens affixed near the base of the corolla, the bases distant, geniculate ; 

 filaments free ; anthers agglutinated with the style-apex, oblong, not 

 bearded ; appendages lanceolate, bearded, caudiform, erect at tip. 

 Pollen granular, composed of 3 to 4 granules cross-wise adherent 

 pollen-carriers discoid, bearing slender caudicles and spathulate often 

 truncate appendicles which carry the poUen-masses. Style-apex 

 capitate, sharply 5-angied. Fruit of 2 slender divaricate follicular 

 mericarps. Seeds oblong, with few silky hairs ending in a tufted long 

 silky coma ; testa thin ; albumen thin ; cotyledons oblong ; radicle 

 cylindric. — Disteib. Species 2, one of the Khasia Hills and Yunan, 

 the other of the Malay Peninsula and Archipelago. 



This genus comes very near to Phyllanthera, with which we are inclined to 

 think it might be incorporated. It differs in the markedly pentagonal style-apex, the 

 bearded anther appendages, and the spathulate not funnel-shaped appendicles of the 

 pollen-carriers. P. khasiana, Kurz, Fl. Br. Ind. IV. 4, hardly seems to us to belong 

 to this genus. 



Pentanuea sumateana, Blume Mus. Bot. Lugd.-Bat. I. 125, t. xxi. 

 (1849). A glabrous slender climbing shrub, with thin angled or 

 striate branchlets, bearing occasional round lenticels. Leaves charta- 

 ceous; elliptic, rather abruptly acuminate at apex, cuneate at base; 

 glabrous on both sm'faces, the lower pale, almost glaucous ; the margins 

 strongly recurved ; 3 to 4 in. long, 1-25 to 1-75 in. broad ; midrib 

 slender, slightly impressed above, raised beneath ; main nerves 7 to 8 

 pairs, slightly raised beneath, at or a little less tlian right angles with
