Endemic. 



A very curious and pretty dwarf species, well suited for pot cultivation. 



Averrhoa Carambola, L., Kamaranga, S., and A. Bilimbi, L., Bilin, S., 

 are both common in gardens. There are specimens of both in Hermann's 

 Herbarium, and they may have been introduced by the Portuguese from 

 the New World, but they are not known anywhere in a wild state. 

 Figured in Bedd. Fl. Sylv. t. y] and t. 117.
