W. Dbocan Peninsttla ; from the Concan southwards. 



Stem 2-5 ft., subsimple below. Leaves 2-5 in., from obloog to subcordate-ovate. 

 Cymes dense, forming a narrow interrupted panicle. Calyx-lobes |-1 in., narrowly 

 (or not) winged. Corolla-lobes IJ in., ovate, acute. Anthers p-^ in. wide at the 

 base. Capsule ^ in., oToid. — The finest species of the genus : in its straight buds and 

 subsymmetric flowers it resemUles BJ. tetragmimn on a large scale.

'Deccan Peninsula, frequent from the Concan and Orissa to Courtallum. 

 Considered by Mr. Bentham only a form of E. tetragowwm, but differs from that 

 (and the larger E. Ferrottetii) in the unsymmetrie flowers, the buds distinctly curved 

 at the tips, and the anther-cells curved and tapering upwards. The calyx-lobes do 

 not taper gradually as in E. Ferrottetii. The flowers are larger than those of E. 

 tetragonum, smaller than those of E. Ferrottetii. The corolla-segments are (very 

 generally) white in the lower half, fuU azure-blue in the upper. 



5. E. azillare, Thwaites Enum. 203 ; stem quadrangidar, leaves ovate- 

 lanceolate 3-nerved thin succulent, flowers mostly solitary on axillary peduncles, 

 calyx-lobes with a dorsal cordate-lanceolate reticulated wing, anthers \ in. 

 straight shortly suddenly beaked. 



Ceylon; in the Pasdoon Corle, Walker, Thwaites. 



Stem 6-18 in., procumbent and branched or erect and simple. Leaves 2 J by 1 in, 

 base tapering, lower mostly long-petioled, very thin, dried retieulately nerved. 

 Fedv,noles J-J in., numerous, often from the lower axils ; upper imperfectly corymbed. 

 Calyx-lobes ^ in. ; wing (in young fruit) \ in. broad. Corolla-lobe J in., lanceolate, 

 acute, cyaneous ( Thwaites). Capsule J by | in. 



Vae. pentamera ; corolla-lobes 5 broader shorter obtuser than in E. axillare type. 

 ^Ceylon, Thwaites. — A dubious plant, perhaps more nearly allied to E. Walkeri, but 

 in the thin succulent leaves and cordate calyx-wings altogether resembling E. axillare. 



** Corolla large or medium-sized, lobes 5 (all from the Deccan Peninsula 

 or Ceylon). 



6. E. Walkeri, Am. in Ann. Sc. Nat. 2, xi. 176 ; leaves ovate or lan- 

 ceolate acute 3-nerved, peduncles axillary solitary and terminal subcorymbose, 

 calyx-lobes with an ovate-lanceolate dorsal wing, coroUa-lobes ^ in. broadly 

 elliptic, anthers J-| in. subtruncate. Griseb. Gentian. 110, and in DC. Prodar.

Cetlon ; Walker, &c. ; central province, alt. 5000 ft., Thwaites (C.P. n. 38). 



Stems 1-3 ft., suberect, often with long branches from near the base, quadran- 

 gular or obscurely 4-lineolate. Leaves (in the original E. ovale) 1 by | in. ovate, 

 acute, base rounded, subsessile (in Thwaites E. zeylanicum, var. /3), 2f by | in., Ian- . 

 eeolate, acuminette at both ends. Calyx-lobes J in., base of wing narrowed or rounded, 

 rarely cordate. Corolla-lobes acute, white or pale blue. Capsule \-^ by 1 in. — E. 

 ovale of Griseb. has been reduced by Thwaites to E. macranthum, but the coroUa- 

 lobes are described by Grrisebach as 8 mill, long, and it was doubtless = E. Walkeri, 

 as is £. ovale of Wight's and Gardner's Herbarium. In this species 1-flowered 

 peduncles from the lower axils are frequent.
