Planta valde variabilis. Caules simplices v. ramosi, basi repentes ad 

 nodos setas stipulaeformes crassas 2 v. plures gerentes v. omnino nudi. 

 Folia plerumque basi cordata, 2-4", subcoriacea, superne glaberrima 

 V. hispidula. Pedicelli patentes ; flores Isete rosei v. albi, interdum 

 purpureo-variegati, 1-2" lati, locis humidioribus umbrosisve de- 

 pauperati. Capsula elliptico-oblonga, utrinque attenuata, vix ^". 

 Semina orbicularia, atra, Isevia, opaca v. subnitida. 

 In Bot. Mag. this plant is erroneously supposed to be a native of 



Ceylon and the whole Himalayan range. Its broad-leaved form is 



certainly the I. chinensis, L., as I have ascertained from the Linnsean 



Herbarium.

Thwaites, En. PI. Ceylon (errata) remarks that Mr. Ferguson, having 

 examined Hermann's plant, considers the I. rosmarinifolia of Retz to be 

 the true Linnean I. oppositifolia, and the fact is, that the two plants are 

 one and the same. It is extremely common, and so variable, that no 

 descriptions, plates, and specimens altogether agree : hence the confusion. 

 /. oppositifolia of Wight and Arnott, as described from WalHch and 

 Heyne's specimens, has the narrow capsule of /. Kleinii, with a short 

 conical, ne^ly straight spur, but in Heyne's, Wallich's, and Wight's 

 specimens, the ripe capsule is broadly elliptical, and the spur often in- 

 curved.
