 under it. Nat. ord. Indian Figs [Cactaceae]. Linn. 12- 

 Icosandria, i-Monogynia.) 



Greenhouse evergreen succulents, with yellow flowers, 

 when not otherwise mentioned. Cuttings, by taking 

 pieces off at the joints, and drying them a little before 

 inserting them in sandy loam, and giving them a brisk 

 bottom-heat. The great point is to give them a high 

 temperature and a moist atmosphere when growing in 



summer, say from 65 to 85 or 90 ; to reduce the 

 moisture gradually as autumn approaches, but not the 

 temperature, until autumn is on the wane ; and then to 

 keep them in a low temperature (40 or 50), and dry 

 during the winter ; sandy loam, fibrous peat, each one 

 part ; lime-rubbish, cow-dung, and charcoal, one-third 

 part each. Vulga'ris has stood in dry situations out of 

 doors near London, and has been unhurt when planted 

 at the foot of a wall, and wet excluded during winter. 

 All species of which we know nothing but the names 

 have been omitted.
