 rower, more or less attenuated leaves, shorter, interfoliaceous 

 peduncles, which are not disposed into a terminal thyrse ; and in 

 the corolla, which is always scarlet, of a deeper colour towards

 ovarium is really surrounded by a ring instead of glands.

Whorled-fiowered Gesneria. PI. 1 foot. 



N.B. What is Gesneria acaulis, Lin. ? 



Cult. All the species of this genus are very showy while in 

 flower ; they are, therefore, great favourites with collectors. A 

 light rich soil, or a mixture of loam, peat, and sand, answers 

 them best. Most of the species are readily propagated by cut- 

 tings, and by the tubers of the root. The roots while in a 

 dormant state should have no water given to them.
