KOELLA. 



A genus of Campanulacece, from the Cape of Good Hope, 

 many of the species very beautifal, the one here described 

 being not the least important in that respect, although, like 

 many other fine plants, it is difficult to manage. The soil 

 should be the best peat that can be obtained, adding silver 

 sand in the proportion of about a third of the whole, to- 

 gether with some pieces of charcoal, which will be found very 

 beneficial. If the plant shows any signs of starting into 

 fresh growth, the potting may be done early in spring, after 

 which it should be stood in a light place, with a temperature 

 of about 60° by day, and, of course, some five or six degrees 

 lower at night. ' Great care must at all times be taken that 

 the plants are not over- watered. As the season advances, the 

 growths should be gently syringed on bright mornings, when 

 the sun's rays will dry up all the superabundant moisture ; 

 and air must be freely given, to encourage free strong growth.
