The limeberry is used for hedges 

 and shrubbery where the winters 

 are sufficiently mild, and is said 

 tot be tolerant of a considerable 

 amount of salt in the soil. 



The generic name Limonia has 

 been used for Triphasia, which is 

 considered separable from that genus. The limeberry is 

 spoken of sometimes as a citrus, which is proper only when 

 the name is used in the most general sense and even then 

 may lead to confusion with the deciduous hardy orange, 

 Poncirus, which has been called Citrus trifoliata. 

 Glabrescent: leaflets 3. T. trifolia.
