Symb. iii. 15 ; Wall Cat. 4359 ; Thwaites Enum. 203 ; Clarke in Journ. Linn. 

 Soc. xiv. 427. E. pedunculare, Am. in Ann. Sc. Nat. 2, xi. 176 ; Wight Ic. t. 

 336. E. sulcatum, Koxl. FL Ind. ed. Carey Sf Wall. i. 415; Griseb. in DC. 

 Prodr. ix. 46, syn. excl. E. rivulare, Edyeiv. Catal. PL Banda, 51. 



Throughout INDIA, ascending to 3000 ft., from Oudh and Bengal to CEYLON, 

 Thwaites (C.P. 1876 in Herb. Kew), &c. 



Stem 3-12 in., quadrangular. Leaves If by in. Peduncles ^-^ in. Calyx-lobes 

 -4 in., ovate, acuminate; wing distinct, lanceolate. Corolla-lobes \-^ in., elliptic. 

 Anthers ^ in., scarcely attenuate upwards, dehiscing finally halfway to the base. 

 Capsule % in., subglobose. Linnseus' species is founded on Pluk. Aim. Mant. t. 343, 

 fig. 3, and Grisebach throws doubt on the identification by saying that Plukenet's 

 figure is bad ; but it seems unusually good and characteristic. 



12. E. pumilum, Griseb. in DC. Prodr. ix. 46 ; stem erect branched 

 upwards, leaves sessile lanceolate 3-nerved, cymes lax, pedicels slender, corolla 

 purple-blue. Wight Ic. t. 1324; Dalz. $ Gibs. Bomb. FL 157; Clarke in 

 Journ. Linn. Soc. xiv. 427. 



The CONCAN ; Belgaum, Graham, Dalzdl, &c. 



Closely allied to E. pedunculatum, but slenderer. Leaves usually narrower ; lower 

 often 1-nerved. Flowers less numerous ; pedicels (many of them) |-1 in. Calyx- 

 u-ings narrower, lanceolate, sometimes obsolete. Anthers dehiscing finally often to 

 the base. 



13. E. sessile, Linn. ; Griseb. Gentian. 113, and in DC. Prodr. ix. 47 ; 

 leaves small sessile ovate, pedicels lateral and terminal very short cernuous, 

 calyx-lobes ovate acute not winged, corolla white. Vahl Symb. iii. 16 ; Wight 

 Ic. t. 1324. E. macrantherum, Miq. PL Hohenack. n. 582. 



DECCAN PENINSULA ; Mangalore, Hohenacker. CEYLON ; common up to 2000 ft., 

 Macrae, &c. 



Stem 4-8 in., erect, quadrangular, simple or corymbose upwards. Leaves ^ by 

 in., obscurely nerved, acute or subobtuse. Peduncles 0- in., axillary, 1-flowered; 

 terminal peduncle appearing sometimes 1 in., but then bearing a pair of small leaves 

 near the flower. Calyx-lobes ~ in., herbaceous. Corolla-lobes - in., elliptic. 

 Anthers ^ in. Capsule in., subglobose. The examples marked E. macrantherum, 

 Miq., are certainly E. sessile, Linn., but are mixed with E. pumilum, and the locality 

 Mangalore is therefore not certain. 



14. XS. X*awii, Clarke ; leaves small sessile ovate, cyme few-fid, lax, 

 pedicels mostly elongate, calyx-lobes ovate strongly nerved not winged, corolla 

 purple-blue. E. sessile, Clarke in Journ. Linn. Soc. xiv. 427, as to the Bombay 

 examples. 



The CONCAN and MALABAR; Bababoodan hills, Law ; Belgaum hills, Eitchie. 



Stem 3-6 in., erect, slender, quadrangular, simple or slightly branched upwards. 

 Leaves % in. long and broad. Peduncles terminal or subterminal, many of them ^-2 

 in. without leaves or bracts. Calyx-lobes |~ in., patent, much-nerved at flower-time. 

 Corolla-lobes f- in., elliptic or round. Anthers ^ in. Capsule |- in., ovoid. 

 Named E. sessile by all collectors, but the flowers are larger, and the inflorescence 

 altogether different. 



15. E. petiolare, Griseb. in DC. Prodr. ix. 46; leaves petioled elliptic 

 or ovate mostly 5-nerved, peduncles erect, calyx-wings broad, corolla white or 

 pale blue. Wight Ic. t. 1324 ; Dalz. 8? Gibs. Bomb. FL 157 ; Clarke in Journ.
