2. E. Roxburg-hii, G. Don Oen. Syst. iv. 206 ; radical leaves numerous 

 persistent obovate or elliptic cauline smaller narrower, cymes repeatedly dicho- 

 tomous with a long-pedicelled flower in eacli fork, coroUa-tube much longer 

 than the calyx, lohes rose-coloured. Griseh. Gentian. 145, and in DC. Prodr. 

 ix. 59 ; Dalz. ^ Gibs. Bomb. Fl. 167. E. ramosissima, Var. a and /3, Clarice in 

 Jmjtm. Linn. Soc. xiv. 428, not of Pers. Ohironia centaurioides, Itoxb. Fl.. 

 Ind. i. 684 ; Wall. Cat. 4397. 



Throughout India ascending to 2000 ft., from the Punjab and Bengal to Travan- 

 core ; common in Bengal Plain. 



Stem 2-8 in. Radical leaves 1 by ^ in., usually obtuse. Cyme fastigiate or widely 

 dichotomous ; pedicels in the forks usually J-J in. ; bracts not prominent. Calyx | 

 in. Corolla-tube exceeding y in., lobes very small. 



Vae. saxatilis; stem taller panicled, leaves narrowly lanceolate basal leaves dis 

 appearing, flowers in small terminal dusters. — S. Deccan Peninsula. 



3. E. nXeyeri, Bunge ; Ledeb. Fl. Alt. i. 220, and Ic. t. 159 ; radical 

 leaves not rosidate cauline oblong, cyme laxly sparingly dichotomous with a 

 long-pediceUed flower in each fork, coroUa-tube scarcely longer than the calyx 

 lobes white. E. ramosissima and altaica, Gi-iseb. in DC. Prodr. ix. 57. E, 

 ramosissima, var. albiflora, Boiss. Fl. Orient, iv. 67. 



Kashmir and Baltisthan; alt. 5-8000 ft., frequent. — Disteib. Cabul, Central 

 Asia to the Altai. 



Stem 4-10 in., undivided below ; radical leaves 2 or at flowering time. Leaves 5 

 by ^ in., subobtuse. Pedicels of the flowers on the forks \-^ in. — It is not clear why 

 Grisebach and Boissier, while maintaining several Erythrseas as distinct species, 

 reduce this to E. ramosissima, from which it is remote in its undivided stem and 

 long-pedicelled flowers, which are invariably white. It is in fact much nearer E. 

 Roxbnrghii. / 



4. E. babylonica, Griseb. in DC. Prodr. ix. 60 ; stem quadrangular,, 

 radical leaves not rosulate, cauline oblong remote, cyme laxly dichotomous, 

 branches erect all the flowers subsessile rose-coloured. E. spicata, var. Boiss. 

 Fl. Orient, iv. 69 ; Clarke in Jmii-n. lAnn. Soc. xiv. 428. E. ramosissima and 

 linarifolia, Clarke I. u., not of Per soon. 



Punjab ; Falconer ; Lahore, Brandis. — Disteib. Cabul, Persia. 



Stem 6-15 in., simple below, acutely quadrangular. Radical leaves 2-0 at flower- 

 ing time. Leaves J by J in., scarcely acute. Cyme symmetrically dichotomous ; 

 pedicels of the flowers in the forks scarcely ^ in. Calyx J in., nearly equalling the 

 corolla-tube. — Considered by Bentham and Boissier a var. of E. spicata, Pers., which 

 differs only by its unilateral cyme-branches. E. babylonica has been misunderstood, 

 because Grisebach described the flowers as 4-merous, whereas in Aucher-Elo/s n. 

 2432 (Grisebach's type) they are 6-merous. The Cabul examples identical with this 

 are called by Boissier E. caspioa, and it is very diflScult to say how they differ except 

 in the strict cymes forming an elongate panicle. 



7. CANSCORA, Lamk. 



Annual herbs, dichotomously branched. Leaves opposite, sessile, petioled 

 or perfoliate. Flowers in terminal or central cymes, or axUlary solitary, or 

 densely spiked on scapes. Calyx tubular, 4-toothed, terete striate keeled or 

 winged. Corolla-tube cylindric, about as long as the calyx ; lobes 4, more or 

 less unsymmetric, imbricate in the bud. Stamens 4, near the summit of the 

 coroUa-tube ; 1 or 2 larger with longer filaments and fertile ovate or oblong 

 anthers ; 3 or 2 with shorter (often lower-attached) filaments, smaller, barren 

 or sometimes subobsolete. Ovai-y 1-celled, placentae not far intruded ; style
