GESNERACEiE. 



[Perigynous Exogens. 



They are generally plants of considerable beauty, often gi-owing on trees and leading 

 a quasi-parasitical life ; but they can scai-cely be said to have any useful quaUties. The 

 succulent fruits of some Gesnerese ai-e mucilaginous, sweetish, and eatable ; and a dye 

 is obtained from the calyxes and fruit of others, for stammg cotton, sti-aw-work, and 

 domestic utensils. Columnea scandens is called by the French colonists Liane a sLrop, 

 because its flowers secrete a large quantity of honey, and Sarmienta repens is used as an 

 emolhent m Chih. Some Didymocarps would appear to be aromatic ; and Picna, a 

 Cochin-Chiua plant, is so bitter as to be called Fel Terrse ; it is, however, very doubtful 

 whether that plant belongs to this Order. It is possibly a Gentianwort.
