Description. A genus of about thirty species of 

 hardy or greenhouse annual or perennial herbs 

 (ord. Solanaceae), best known in this country by the 

 use made of the fruits of Alkekengi and Fran- 

 cheti, which have fine red inflated calyxes. The 

 fruits of peruviana edulis, the Cape Gooseberry, 

 are used occasionally for dessert. Those of Alke- 

 kengi are also said to be edible. Francheti is 

 much the finest. 



Propagation. The annuals by seeds, sown in 

 spring ; the perennials by seeds or by division at 

 the same season.
