80 LXXV. EUBiACEJ!. (J. D. Hooker.) [Opkiorrhiaa* 



late acute, stipules subulate, cymes subcorymbose many-flowered rounded, brae- 

 teoles long linear or filiform deciduous, calyx-teeth subulate, corolla glabrous 

 tip 5-angled in bud, capsules glabrous. 



NILGHERRY MTS., Wight, &c. COCHIN, Johnson. 



The rounded cymes, and numerous long subpersistent bracteoles, are good charac- 

 ters for the species. Leaves 3-4 in., usually ovate or ovate-lanceolate, base acute,, 

 very membranous ; petiole slender. Cyme-peduncles - in., longer in fruit. Corolla 

 i in. long, cylindric, lobes narrow. Capsules crowded, in. diam. 



VAR. ?Johnsoni; corolla narrower and longer in. puberulous. Cochin, John- 

 son. 



VAR. ? hirsutior, Wight mss. ; branches petioles and cymes densely tomentose. 

 Nilgherry Mts., Gardner. I have seen neither flower nor fruit of this. 



11. O. gracilis, Kurz in Joum. As. Soc. 1872, ii. 311 ; annual, erect, 

 perfectly glabrous, leaves lanceolate with very long slender points, cyme long- 

 peduncled, branches slender, bracteoles subulate, calyx-teeth minute, corolla- tube 

 | in. terete glabrous. 



TENASSERIM, Kurz ; BIRMA, Brandis. 



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. 



12. O. radicans, Gardn. in Thw. Enum. 139; stems densely tufted' 

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

 nerves beneath petioles and cymes pubescent, stipules minute subulate, cymes 

 small few-flowered contracted, bracteoles few subulate, calyx-teeth subulate,, 

 corolla small, lobes short keeled on the back. 



CEYLON ; Central Province, Gardner, Thwaites. 



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

 peduncles usually shorter than the leaves, but sometimes longer. Corolla - in. long* 

 Fruit not seen. 



13. O. oppositiflora, Hook. f. ; stem erect woody and petioles leaf- 

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

 acute glabrous rather rigid, stipules subulate, cymes terminal and opposite in the 

 leaf-axils corymbose many-flowered, bracteoles minute or 0, calyx-teeth lanceolate 

 obtuse, corolla ^ in. glabrous within and without tubular 5-angled, lobes oblong 

 obtuse keeled. 



KHASIA MTS. (tropical ?), C. B. Clarke. 



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

 axils of all the 3-5 upper pairs of leaves, f-1 in. diam. ; peduncles slender, -1 in. ; 

 branches erect ; flowers numerous, slender, erect. A very remarkable species, the- 

 only one with opposite cymes. 



** Bracteoles very slender, persistent or subpersistent. Corolla an inch or more 

 long, pubescent or hairy, lobes broad acute. 



14. O. grandiflora, Wight Ic. t. 1069 ; erect, glabrous except the hairy 

 corolla, leaves elliptic-lanceolate acuminate, stipules minute lanceolate, cymes 

 contracted, bracteoles very long filiform, calyx-tube ribbed teeth lanceolate, 

 corolla 1-1 in. hairy, tube slender funnel-shaped above glabrous within, lobes 

 large broadly ovate acute, capsules glabrous. 



THE CARNATIC ; Shevagherry hills, Wight. 



An erect undershrub. Leaves 5-7 in., membranous, almost caudate- acuminate. 

 Cymes 1-1 in. diam.; peduncles short, -1 in.; branches suberect; bracts and 

 bracteoles -1 in. Calyx-teeth equalling the tube. Corolla f in. across the lobes. I 

 have seen no fruit.
