ROHH.K.UND, Royle, T. Tkomson. BEHAR, Hamilton. WESTERN PENINSULA, Wight, 

 &e. 



A very slender erect species, resembling a state of 0. bijlora, with paniculate 

 terminal inflorescence. According to the rules of priority, the name of 0. piusttla 

 should take precedence, but it is not applicable. 



9. O. dichotoma, Koen.\ Roth Nov. Sp. 93 (Hedyotis); annual, very 

 slender, glabrous or sparsely hairy, stem erect terete, nodes distant, branches 

 filiform, leaves linear-lanceolate acute flfft nerveless, peduncles capillary axillary 

 and in open terminal panicles, pedicels very long, calyx-teeth subulate much 

 shorter than the slender corolla-tube, capsule globose. O. linarifolia, Herb.

BANDELKTJND and southward through the WESTERN PENINSULA to Travancore, on 

 <lry hills, alt. 1-3000 ft., Bottler, &c. 



Stem simple in small plants, much branched in large ones, 18 in. high ; branches 

 sinning, divaricating, copiously flowering throughout their length, ultimate ones and 

 peduncles and pedicels like fine hairs, 1 in. and more long. Flowers very minute. 

 <'apsules smaller than in its congeners, cells about 6-seeded. Beddome's figure is, I 

 think, this plant; it does not agree with his description, called H. Heynii (t. 33). 



10. O. arguta, Br. in Wall. Cat. 864 (Iledyotis) ; annual, erect, stiff, 

 stem simple or 3-chotomously branched furfuraceous or hispid, leaves semi- 

 -amplexicaul subulate or triangular-lanceolate acuminate scabrid, margins revo- 

 lute, cymes terminal lax few-flowered scabrid, peduncles and pedicels filiform, 

 calyx-teeth subulate-lanceolate shorter than the funnel-shaped corolla-tube and 

 longer than the didymous hemispheric hispid capsule. Hedyotis linoides, Griff. 

 Notid. iv. 265 ; Kurz in Journ. As. Soc. 1877, ii. 134. 



MARTABAN and TENASSERIM; Moulmein, and Mergui, in wet sand, Gome~, &c. 



A few inches to a span high ; branches terete, spreading. Leaves % in., rigid, pale 

 beneath. Cymes twice or thrice forked ; flowers blue. Seeds ellipsoid, angled, testa 

 smooth. 



11. O. Stocksii, Hook. /. $ T. Herb. Ind. Or. (Hedyotis); tufted, 

 glabrous, stems filiform simple or branched above, leaves subulate, stipules with 

 bristles, cymes with few very large flowers, calyx-teeth elongate subulate 

 almost equalling the very broadly campanulate corolla-tube. 



MALABAR ; in the Bababooden hills, Stocks, Law. 



A very slender annual, apparently growing in masses amongst grass, 4-8 in. high. 

 Stems simple below or throughout their length, branches ending iu di-trichotomous 

 cymes, with capillary pedicels. Leaves (not fascicled) -^ in. Calyx-tube short, 

 obconic, much smaller than the long erect or recurved teeth. Corolla much the 

 longest of the genus, quite campanulate, blue, - in. diam. Capsules hemispheric 

 or turbinate. smooth. 



ux. II. Kohautia. Corolla-tube usually long cylindric or funnel- 

 shaped, with included or shortly exserted anthers. Ovary terete. Seeds nume- 

 rous, angled. Usually strict erect, annual or perennial herbs, rarely diffuse, 

 sometimes shrubby below with stiff erect branches, very narrow leaves and 

 terminal open cymes ; stipules with bristles. 



* Corolla-tube very slender.
