Throughout the Deocait Pbkinsttla, alt. 0-4000 ft., from S. Behar {J. D. S.) to 

 Coorg ( Wight) ; common. 



Stems 1-2 ft., branching, weak, hairs soft patent white. Leaves 2J by 1-1' in., 

 acuminate at both ends, sparsely hairy, obscurely (or not) lineolate ; petiole 1-lJ in. ; 

 leaves on the secondary flowering branches much smaller. Bracts ovate or elliptic, 

 scarcely longer than the calyx, or of the outermost flowers petioled, and greatly 

 exceeding the calyx. Sepals ^-^ in., sabequal, linear-lanceolate, whitened, hairy not 

 obviously lineolate. Corolla |-| in., nearly straight ; tube pale or yellowish, 

 gradually narrowed upwards, limb blue. Shorter filaments glabrous ; anthers nar- 

 rowly oblong, cells triangular acute (not awned). Capsule i in., rarely L ju.^ 

 minutely patently hairy, 6-seeded. — This hardly difiers from S. elegans, Nees, but 

 by the smaller capsule with 6 (not 8) seeds. T. Anderson considered them one. 



Vae. rupestris ; more pubescent, often viscid aromatic, heads denser. Bnellia 

 diffusa. Wall. Cat. 2383, letters C, D. R. satpoorensis, Wawra in Oestr. Sot. Zeit. 

 1881, 281, and in It. Pr. Cob. Bot. i. 90, t. 8 B.— Deccan Peninsula, Chota Nagpore, 

 Bajpootana. N.W. Himalaya, alt. 2-5000 ft. ; Eumaon, Strachey Sf Winterbottom ; 

 Sewaliks, Stewart. — Even commoner than the type, more rigid, growing in drier places. 

 It was distributed as Suellia rupestris to Wallich and to Roth (see Both Nov. Sp. 

 307). The authentic sheet named by Heyne in Herb. Bottler coDsists partly of this, 

 partly of Lepidagathis fasciculata. 



Vae. Beddomei ; much less hairy, leaves small ovate serrate or crenate glabrate. — 

 Bellary; Beddome. 



6. K. ebracteolata, Glarhe; tispid with scattered white hairs, 

 leaves small petioled ovate serrate, bracteoles 0, capsule j in. 6-seeded. H. 

 rupestris, T. Anders, in Journ. Linn. Soc. ix. 462, partly. BueUia ebracteo- 

 lata, Dalz. in Hook. Kew Journ. ii. 342. B. latebrosa, Dalz. Sf Gibs. Romb. 

 Fl. 186. 



Bombay Ghats ; Dalzell, Stocks. 



Leaves 1\ by 1 in. (mostly smaller), obtuse or very shortly acuminated, base 

 obtuse or almost rounded, cuneately decurrent on the petiole, coarsely toothed, hairs 

 stiS" (almost bristly) especially on the nerves beneath ; raphides plentifiil but obscure. 

 Otherwise altogether as S. latebrosa, 'Sees, of which Dalzell finally considered it a 

 form. — R. rupestris, T. Anders., is made up of Buellia rupestris and of M. ebracteolata, 

 Dalz. ; but Dalzell's M. ebracteolata is much remoter from B. rupestris than is the 

 latter from Semigraphis latebrosa, Nees. 



7. H. flaccida, Clarke; stems long softly patently hairy, leaves 

 petioled ovate or elliptic subentire or obsoletely crenate, heads small few- 

 fld., bracteoles 0. Ruellia flaccida, Kurz in Journ. As. Soc. 1873, pt. ii. 91. 



Pegu; Kurz. 



Longer filaments bearded upwards, shorter naked. Bracts not fimbriate nor flowers 

 solitary (as Kurz describes). Capsule not seen.— As Kurz admitted H. latebrosa to 

 be of the genus Semigraphis, he erred in placing this species in Buellia; for it is 

 closely allied to H. latebrosa. The white hairs on the stems are ^ in. long, very 

 copious, nearly similar to those of H. latebrosa. If this is well separable from S. 

 latebrosa, it must be by the very entire leaves ; in S. latebrosa the larger leaves (on 

 the principal stem) are always prominently toothed. 



8. H. elegrans, Nees in DC. Prod/r. xi. 722, of T. Anders, partly ; 

 difiEuse, patently softly white-hairy, leaves petioled ovate or elliptic crenate- 

 serrate, bracteoles 0, capsule i in. 8-10-seeded. Buellia difiusa. Wall.
