Not uncommon in the PLAINS of INDIA from Kohilkund southwards and eastwards, 

 but local. EAST BENGAL, Griffith (Kew Distrib. 2912). CHITTAGONG, C. B. Clarke. 

 DECCAN not uncommon. (Not found yet in East Himalaya, Assam, the Khasia or 

 Malay Peninsula). DISTRIB. Java. 



A diffuse flaccid herb ; branches 2-3 in. Leaves |- in. The large calyx-teeth 

 well distinguish this from any of the foregoing species. The tissues are sometimes 

 full of raphides, as in some states of 0. corymbosa. 



** Peduncles from the upper axils chiefly, many-flowered. 



5. O. umbellata, Linn.; DC. Prodr. iv. 425-, annual, diffuse, glabrous 

 or scaberuloiis, leaves often fascicled linear flat or almost acicular with recurved 

 margins acute nerveless, peduncles in the upper axils stout 3-many-flowered, 

 pedicels short, calyx-teeth a little shorter than the corolla-tube subulate, capsule 

 didymous, crown low. Roxb. Coi\ PL t. 3 ; Fl. 2nd. i. 421. O. puberula, G. Don

WESTERN PENINSULA, from Orissa southwards, Roxburgh, &c. CEYLON, common. 

 DISTBIB. N. Birnia, Kurz. 



Stem woody, much branched from the base. Leaves |-1 in., spreading or recurved. 

 Cymes sometimes sessile and terminal. Capsules much as in 0. corymbosa. 



6. O. Wight!!, Hook. f. ; perennial, scabrid, stem woody flexuous, 

 branches rigid diffuse leafy, leaves squarrose linear-lanceolate acuminate, 

 margins revolute, peduncles chiefly in the upper axils strict with terminal 

 capitate cymes, calyx-teeth triangular-lanceolate pungent equalling the broad 

 hemispheric didymous capsule. 



WESTERN PENINSULA, Herb. Wight (Kew Distrib. 1511). 



Stems creeping in red soil or prostrate, several inches long ; branches 4-6 in., 

 tufted, erect or ascending. Leaves -1 in., sessile, pungent, scabrid on both surfaces ; 

 stipules short, bristly. Peduncles usually exceeding the leaves, stout, scabrid. Heads 

 $ in. diam. ; flowers sessile. Capsules large, scabrid, with a broad low crown and 

 long spreading teeth. This approaches a Hedyotis of the section Scleromitrion, but 

 the foliage is not that of the majority of that groxip, and the form of the capsule and 

 distant calyx-teeth well distinguish it. 



*** Flowers sessile, chiefly in the upper axils, solitary or crowded; corolla 

 rotate. (See also 2. 0. diffusa.) 



7. O. trinervia, Retz Obs. iv. 23; annual, glabrous or hairy, branched 

 low diffuse leafy, leaves small subsessile ovate elliptic or orbicular, nerves 

 distinct, flowers solitary or clustered in the axils sessile or subsessile, calyx- 

 teeth very short equalling the rotate corolla, capsule small cUdymous hairy 

 crown low. 0. repens, Burm. Fl. Ind. t. 15, f. 2 ? Hedyotis trinervia, W.
