178 TRIANDR1A MONOCYNIA. XyTlS. 



sules erect, three-sided, clavate; pedicel included, about half 

 an inch long-, three-celled, opening- at the apex. Seeds very 

 numerous, and too minute to admit of my ascertaining their 

 internal structure. 



2. S. emacitlata. Roxb. 



Leaves opposite, unequally narrow-cordate, acute, bristly, 

 but void of spots, serrulate, ciliate. 



A native of the Khassee mountains on the north-east 

 border of Bengal, where it flowers in July, and differs from 

 the preceding- species, in the leaves being- destitute of the 

 little round white spots, into which the bristles are inserted, 

 (viz. one in the centre of each spot.) It is also less robust 

 than that plant, with longer peduncles to the racemes, which 

 are sometimes leaflet-bractcd at the middle. 



The flowers and seed vessels are alike. 



3. S. megustifolia. Roxb. 



Leaves opposite, unequally oblong-lanceolar, serrulate, 

 hairy. 



A native of the mountains on the north-east border of 

 Bengal, and like the two former species in habit, but the 

 shape of the leaves widely different, and only a little hairy. 



4. S. moluccana. R. 



Sub-caulescent. Leaves in pairs, entire, hairy, one minute 

 and nearly round, the other unequally cordate. Racemes 

 umbelled.
