Throughout INDIA, alt. 0-1500 ft. ; from the Punjab and Gangetic Plain to 

 CEYLON ; more frequent near the sea, not known in Bengal. DISTRIB. Malaya, Tropical 

 Africa, W. Indies. 



Stem 4-20 in., terete or quadrangular, internodes short. Leaves 2 by in., or 

 small or sublinear. Calyx ^ in. ; lobes narrowly oblong, obtuse. Corolla-tube in. ; 

 lobes ~ in., elliptic. Capsule %- in. Seeds small, but much larger than in the pre- 

 ceding genera. 



6. ERYTHRJEA. L. C. Rich. 



Herbs, annual or perennial, erect, branched. Leaves opposite, sessile. 

 Cymes dichotomous, dense or corymbose, rarely elongate ; flowers rose, white 

 or (in non-Indian species) yellow. Calyx tubular ; teeth 5, lanceolate or linear, 

 keeled. Corolla-tube long or short ; lobes 5, spreading. Stamens 6, near the 

 summit of the corolla-tube, filaments short linear ; anthers narrowly oblong. 

 Ovary 1-celled, placentae far intruded; style linear, stigmas semicircular or 

 oblong. Capsule oblong, about as long as the calyx, nearly 2-celled, 2-valved, 

 capsules separating. Seeds very small, reticulated. Species 20, throughout the 

 N. Hemisphere, extending to Chili and Australia. 



The Indian species have all an elongate corolla-tube, as long or longer than the 

 calyx, and the corolla-lobes elliptic or oblong, small, much shorter than the tube, 

 and would be by some authors all referred as varieties to E. ramosissima, Pers. 



1. E. ramosissima, Pers. Syn. i. 283; radical leaves not rosulate 

 cauline oblong or elliptic acute, flowers rose-coloured clustered sessile promi- 

 nently bracteate, calyx-teeth long linear about equalling the corolla-tube.

PUNJAB, alt. 1-2000 ft. ; Loodiana, Hooshiapore, Thomson, Edgeworth, &c. 

 DISTRIB. Cabul and Beloochistan, "W. Asia and Egypt. 



Stem 3-15 in., very leafy. Leaves 1| by f in. Calyx ^ in. ; teeth prominent, 

 overtopping the buds almost till the moment of opening. This Punjab plant is not 

 exactly the type of E. ramosissima, being often tall, leafy, the flowers in clusters 

 enveloped with bracts, the calyx-teeth substellate ; the same form extends through 

 Asia to Egypt. 



VAR. caspica; upper leaves oblong-linear, cyme repeatedly dichotomous. E. 

 caspica, Griseb. Gentian. 145, and in DC. Prodr. ix. 59. Punjab (?j, Falconer. 

 Cabul and the Caspian region. 



VAR. pulchella, Griseb. Gentian. 137; stem slender, cauline leaves \-\ in. oblong 

 or ovate obtuse, cymes depauperated, calyx-teeth not prominent. Skardo, alt. 7-8000 

 ft., Thomson. Distrib. Central and W. Asia. This is not exactly the same as Fries' 

 E. pulchella, but it is included under E. ramosissima by Boissier, 1. c. Hk. f. $ T. in 

 Herb, marked it E. tenuiflora, Link (FL Port. i. t. 67), which again is oniy a var.^ of 

 E. latifolia, Griseb. ; but the true E. latifolia, Smith, differs considerably, having 

 larger flowers and being allied to E. Centaurium.
