 very membranous ; petiole slender. Ot/me-pedtmcles ^-^ in., longer in fruit. Corolla 

 1 in. long, cylindric, lobes narrow. Capsules crowded, \ in. diam. 



Var. ?Johnsoni; coroUa narrower and longer f in. puberulous. — Cochin, John-

I have seen a single specimen only. It is at once distinguished by the very long- 

 slender points of the membranous leaves, which are 5-9 in. long and rather oblique.

 slender creeping, leaves small ovate-cordate or orbicular obtuse glabrous above

 corolla small, lobes short keeled on the back. 



Cetlon ; Central Province, Gardner, Thwaites. 



Stems flexuous, a foot long, rooting at every node. Leaves J-| in. diam. Cyme- 

 peduncles usually shorter than the leaves, but sometimes longer. Corolla J-J in. iang> 

 Fruit not seen. 



13. O. opposltiflora, Hook. /. ; stem erect woody and petioles leaf.- 

 nerves beneath and peduncle appressedly rusty-pubescent, leaves ovate-lanceolate

Stem rigid, scabrid, 1-2 ft. Leaves 2-3 in. ; petiole slender. Cymes often in th» 

 axils of all the 3-S upper pairs of leaves, j-l in. diam. ; peduncles slender, J-l in. ; 

 branches erect ; flowers numerous, slender, erect. — A very remarkable species, tlie 

 only one with opposite cymes. 



** Bracteoles very slender, persistent or suhpet'mtent. Corolla an inch or mare-
