Tribe I. 
GESNERIEVE (this tribe contains plants agreeing with Ges- 
neria in the characters given below.) Calyx usually adhering to 
the ovarium at the base; the ovarium is, therefore, half inferior. 
Seeds albuminous. 
Subtribe 1. 
GLOXINIE’ (this subtribe contains plants agreeing with 
the genus Gloxinia in the characters given below.) Calyx ad- 
nate to the ovarium. Corolla half inferior, perigynous.

Cult. The species of this genus are exceedingly beautiful 
when in flower, like most of the other genera of the present 
order. A mixture of sand, loam, and peat is the best soil for 
them. As soon as the plants are done flowering they should 
not have any water given to them until the roots begin again 
to vegetate, when they should be taken out of the pots and 
divided. Five or six strong roots are sufficient for a sixty size 
pot. After this has been done, they require moisture and 
warmth to make them grow strong, and flower in perfection.
