 Summow. Malay, 



Native of the Forests of Pulo Pinang. 



Root fibrous. Stem erect, from six inches to a foot in 

 height, oppositely branched, rounds tinged with red, fringed 

 with two opposite longitudinal lines of hairs (like that of the 

 Veronica Chamaedrys). Leaves opposite, petiolate, ovate- 

 lanceolate, acute at both ends, serrated, villous with erect 

 hairs, three-nerved, green above, reddish beneath. Petioles 

 nearly smooth. Stipules none. Peduncles terminal^ spring- 

 ing from the centre of a four-leaved verticil which terminates 

 the branch, and of which two opposite leaves are smaller. 

 The spike is unilateral, about four-flowered, recurved, 

 smooth ; each flower sessile on the upper side of the clavate 

 peduncle, which is there thickened and as it were scooped 

 out to receive it, and is attenuated downwards to the point 

 of insertion into the branch. Bracts none or very minute. 

 Calyx smooth, trifid, lacinife acute. Corolla of a light flesh 

 color, composed of three lanceolate ovate, acuminate, spread- 

 ing petals. Stamina three, alternating with the petals, erect, 

 scarcely so long as the corolla. Anthers two-celled, acute, 

 cordate at the base. Style erect, equal to the stamina. 

 Stigma obtuse. Ovarium long, linear, inferior. Capsule 

 oblong, obtusely three-angled, three-celled, three-valved, 

 many-seeded, the dissepiments opposite to the valves. Seeds 

 attached to a central columnar three-sided placenta. 



Ohs, — This plant differs considerably in habit from the 

 other species of Sonerila in having an erect slender brachiate
