THE MIXED GREENHOUSE. 



POLYGALA. 



This fine-flowering genus requires the same soil and treatment as the 

 last. 



CHJRONIA 



Is propagated by cuttings taken off in spring, planted in sand, and covered 

 with a bell-glass in a cool situation. A light sandy loam and peat is the 

 most suitable for them. 



PROTEA. 



This fine genus has been subdivided into various new genera. The 

 species which are natives of the Cape of Good Hope are almost all splen- 

 did when in flower, but it is to be regretted that so few of them are at 

 present to be found in our gardens. The late collectors, Niven and 

 Mason, sent many species to the Kew garden, and also to the Hammer- 

 smith nursery, but in both collections few of them are now to be seen. 

 A rich loamy soil is suitable to the majority of them. They are very 

 difficult to increase by cuttings, but seeds of them can be readily obtained 

 from the Cape, and occasionally they ripen seeds in this country. 



ROELLA 



Is multiplied by cuttings of the young wood, planted in sand and placed 

 on a slight heat under a glass. The grown-up plants prefer a sandy peat 

 alone, and small pots. 



SALVIA. 



No genus of plants strikes more freely, or is grown -^ith less trouble. 



SELAGO. 



The Voung shoots root freely in sand, under a glass, in a cool place. 

 Light loam and peat, of each equal parts, will grow them to perfection. 



SWANSONIA. 



Seeds are readily produced, and vegetate freely if sown in peat and loam. 

 Cuttings root with little difficulty, but seedhngs make the best plants.
