The Richardia takes the name from L. C. Richards, a French botanist, 

 and is a genus comprising five species of marsh plants, natives of South 

 Africa, four of which have been introduced for greenhouse cultivation. 



The}^ are of very easy cultivation, the most important point being to 

 give them a plentiful supply of water during their growing season. They 

 will succeed best in a rich soil, made of a compost of good loam and cow 

 manure in equal parts. 



Richardia Africana is the proper name of the variety above referred to

as most grown by amateurs. It is a winter and spring bloomer, and is 

 usually allowed to rest in the summer months, by turning down the pot on 

 its edge and leaving the plant without water; or it may be planted out and 

 left without care until early fall, and then potted. 



R. albo-maculata, or the white spotted Calla, is by far the best of the 

 other three for amateur cultivation. This one is highly prized for its foli- 

 age, which has a variegated appearance, while its greenish-white spathe, 

 though smaller than that of 7-^. Africana, is still very interesting.
