ORDER CXIIL— GESNERIE^. 



The corolla is tubular and sub -bilabiate, with 

 a five-cleft limb. There are four stamens, two

 fifth. The anthers generally adhere in pairs ;

 leaves are thick and covered with a soft down ;

 bright scarlet flowers ; and those of Gloxinia 

 have generally purple flowers ; and of Sinnin- 

 gia the flowers are greenish.
