GESNERACE^E. 



[Perigynous Exogens. 



They are generally plants of considerable beauty, often growing on trees and leading 

 a quasi-parasitical life ; but they can scarcely be said to have any useful qualities. The 

 succulent fruits of some Gesnereae are mucilaginous, sweetish, and eatable ; and a dye 

 is obtained from the calyxes and fruit of others, for staining cotton, straw-work, and 

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

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

 emollient in Chili. Some Didymocarps would appear to be aromatic ; and Picria, a 

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

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