102 XCVII. GENTIANACEEX. (C. B. Clarke.) [ Erythraa, 
2. E. Roxburghii, G. Don Gen. Syst. iv. 206; radical leaves numerous 
persistent obovate or elliptic cauline smaller narrower, cymes repeatedly dicho- 
tomous with a long-pedicelled flower in each fork, corolla-tube much longer 
than the calyx, lobes rose-coloured. Griseb. Gentian. 145, and in DC. Prodr. 
ix. 59; Dalz. § Gibs. Bomb. Fl. 157. E. ramosissima, Var. a and 8, Clarke m 
Journ. Linn. Soc. xiv. 428, not of Pers. Chironia centaurioides, Roxb. Fl. 
Ind. i. 584; Wall. Cat. 4397. 
Throughout Invi ascending to 2000 ft., from the Punjab and Bengal to Travan- 
core; common in Bengal Plain. . 
Stem 2-8 in. Radical leaves 1 by 4 in., usually obtuse. Cyme fastigiate or widely 
dichotomous; pedicels in the forks usually 1-3 in.; bracts not prominent. Calyz; 
in. Corolla-tube exceeding 1 in., lobes very small. . 
Van. saratilis; stem taller panicled, leaves narrowly lanceolate basal leaves dis 
appearing, flowers in small terminal clusters.—S. Deccan Peninsula. 
3. E. Meyeri, Bunge; Ledeb. Fl. Alt. i. 220, and Ic. t. 159; radical 
leaves not rosulate cauline oblong, cyme laxly sparingly dichotomous with a 
long-pedicelled flower in each fork, corolla-tube scarcely longer than the calyx 
lobes white. E. ramosissima and altaica, Griseb. in DC. Prodr. ix. 57. E. 
ramosissima, var. albitlora, Boiss. Fl. Orient. iv. 67. 
Kasuwtn and DBarrisTHAN ; alt. 5-8900 ft., frequent.-—DisrRi». Cabul, Central 
Asia to the Altai. 
Stem 4-10 in., undivided below ; radical leaves 2 or 0 at flowering time. Leaves i 
by à in, subobtuse. Pedicels of the flowers on the forks 1-2 in.—It is not clear why 
Grisebach and Boissier, while maintaining several Erythrwas 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. 
Roxburghii, 
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 Journ. Linn. Soc. xiv. 428. E. ramosissima and 
linarifolia, Clarke l. c., not of Persoon. 
Ponsas; Falconer; Lahore, Brandis.-—Distris. Cabul, Persia. 
Stem 6-15 in., simple below, acutely quadrangular. Radical leaves 2-0 at flower- 
ing time. Leaves } by ẹ in. scarcely acute. Cyme symmetrically dichotomous; 
pedicels of the flowers in the forks scarcely 4 in. Calyx } 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. Æ. babylonica has been misunderstood, 
because Grisebach described the flowers as 4-merous, whereas in Aucher-Eloy's n. 
2432 (Grisebach's type) they are 5-merous. The Cabul examples identical with this 
are called by Boissier E. caspica, and it is very difficult to say how they differ except 
in the striet eymes forming an elongate panicle. 
7. CANSCORA, Lamk. 
Annual herbs, dichotomously branched. Leaves opposite, sessile, petioled 
or perfoliate. Flowers in terminal or central cymes, or axillary solitary, oT 
densely spiked on scapes. Calyx tubular, 4-toothed, terete striate keeled OT 
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 
corolla-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. Ovary l-celled, placente not far intruded ; style
