108 FLOIIA DOMESTICA. 



of the first are of a bright sky-blue, and the plant is never 

 without them the whole year round. Of the second, the 

 inner part of the flowers is white, the outside a most vivid 

 purple : it flowers early in the spring, and, if in a healthy 

 state, will also flower all the year ; but this plant is often 

 infested with a kind of insect which destroys its vigour ; 

 therefore, to ensure a succession of healthy, handsome 

 plants, it should be annually increased by cuttings, which, 

 if planted in September, and placed in a tolerably warm 

 situation, will strike root very readily. 



These plants must be housed in the winter. Many 

 persons keep the last kind in a stove, but, like many of 

 ourselves, they are more healthy when treated less tenderly. 

 The earth must be kept moderately moist. 



CISTUS. 



CISTE^E. POLYANDRIA MONOGYNIA. 



Called also gum cistus, and rock rose. French, le ciste. Italian, 

 cisto, cistio. 



THE Cistus is a very extensive genus, and all the species 

 are valuable ornaments to a garden. Their flowers, al- 

 though of short duration, are succeeded almost every day 

 by fresh ones, for more than two months, and are generally 

 about the size of a rose. They are of different colours, and 

 the plants retain their leaves all the year. 



Some few require a stove ; it will be sufficient to specify 

 the most beautiful kinds which may be preserved without 

 one. 



The Poplar-leaved Cistus, a native of Portugal : flowers 

 white, tinged with purple at the edges ; bloom in June and 

 July. 



The Bay-leaved Cistus, a native of Spain : flowers white; 

 blow in June and July.
