324 PENTANDRIA monogynia. Argostemma. 



haY an inch long, lanceolate, acute, rather narrow downward?, three- 

 nerved, reticulate, that in the middle rather larger, the other two 

 placed oppositely, and forming a straight line, in the centre of wh ch 

 are still to be seen the small subulate teeth which were noticed above ; 

 they are somewhat thick and convex at their base and separable to 

 the bottom of the fruit, which perhaps is three-valved. — N. W. 



ARGOSTEMMA, Wall 



Calyx four or five-toothed. Corolla rotate, fl^t, four or five-part- 

 ed. Anthers conniving, exserted. Berrii^ interior, two-celled, ma- 

 ny-seeded; seeds angular, inserted on a septal placenta. 



A small, succulent, sub-diaphanous, pubescent, elegant, herbaceous 

 plant, growing on rocks; with a simple stem, terminated by a few, 

 opposite, unequilateral leaves. Flowers snow-white, largish with res- 

 pect to the size of the plant, valvate and pyramidal during aestivation, 

 disposed in terminal racemes or umbells. 



In the Linnean system they claim almost an equal right to Te- 

 trandria and Fenlandria Monogynia, in the section with mouope- 

 talous, superior flowers. 



It belongs to Rubiacea of Juss. ; I know of no genus in that ex- 

 tensive family to which it has any very particular resemblance. 



1 A. sarmentosum, Wall, 



Somewhat villous, creeping at the base and stolouiferous. Leaves 

 in two most approximate pairs, ovate, sub-sessile. Elowen tetran- 

 drous.

1 found this elegant little plant on the hills at Shukragin near 

 Rajmahwl, growing on rocks aud blossoming in August. During my 

 stay in Nipal, my people brought me also specimens from the moun- 

 tains to the Northward of the valley on the route to Gosam-Than, 

 in flower during the rainy season*
