Descriptions of Malayan Plants. 



The stem is nearly erect, from one to two feet in height, 

 herbaceous or somewhat shrubby, villous. Leaves alternate, 

 petiolate, obovate, acuminate, narrowing to the base, ser- 

 rated, pilose above, villous below. Peduncles axillary, so- 

 litary, elongated, bearing several dense fascicles of flowers, 

 all turned to one side, depressed or bent at an angle to the 

 peduncle, and spreading in a kind of half-circle, somewhat 

 in the manner of the Lotus corniculatus. Flowers many, 

 white ; pedicels articulate below the calyx, covered as well 

 as the calyx with glandular hairs. Bracts linear, acute. 

 Calyx five-parted; segments linear. Corolla white, much 

 longer than the calyx, infundibuliform, wide at the faux; 

 Umh somewhat oblique, bilabiate, the lower lip longer, 

 three-lobed. Stamina two fertile, connected above by their 

 anthers, whose lobes are transverse. Style as long as the 

 stamina. Stigma capitate. Capsule silique-shaped, two- 

 celled ; cells bipartite (as if four-locular), two-valved, gene- 

 rally bursting at one side, many-seeded. Seeds naked. 



The disposition of the flowers and fruit is peculiar, the 

 capsules spreading horizontally like radii in a sort of semi- 

 circle, of which the peduncle is the axis. 



5. DIDYMOCARPUS ELONGATA. 



D. herbacea erectiuscula didynama, foliis oppositis ovatis 

 utrinque acutis serratis, spicis axillaribus secundis, pedicellis 

 binatis remotis, corolla elongata. 



Found on Pulo Bintangor, an island lying ofl* the west 

 coast of Sumatra. 



A small erect herbaceous plant, about half a foot high, 

 pilose. Leaves opposite, petiolate about five inches long, 

 ovate, acute at both ends, serrated, papillous, and pilose 

 with rather long hairs above, villous beneath with short hairs. 

 Petioles channelled above and ciliate along the edges of the 

 furrow. Stipules none. Peduncles axillary, solitary, bear- 

 ing an unilateral spike rather longer than the leaf. Pedicels
