32. CISTUS PLATYSEPALUS, Broad-sepaled Rock Rose. 



This is pretty plant, but requires some protection in 

 severe weather. 



It thrives best in a sandy loam with peat, and increased 

 by seeds or cuttings. 



It is a native of Crete. 



33. HELIANTHEMUM LINEARE, Linear-leaved Sun Rose. 



This pretty little shrub is well adapted for rock work, 

 but it requires a little covering in the winter. 



It is always safest to have a few plants in pots, so that 

 they may be put into a frame or the green-house. 



It is propagated and managed the same as the rest of 

 the species, and is a native of the South of Europe. 



34. HELIANTHEMUM PILOSUM, Hairy Sun Rose. 



This plant is very pretty, and .well calculated to adorn 

 rock work. It continues in flower nearly all the summer. 

 It is tolerably hardy, but will require shelter in frosty 

 weather. 



The soil, and the mode of management, the same as 

 others of the species. 



35. HELIANTHEMUM FORMOSUM, Beautiful Sun Rose. 



This plant is considered to be the largest flowering spe- 

 cies of the genus, and makes a very handsome bushy 

 shrub. It must be protected in severe weather. It pro- 

 duces a great quantity of flowers in succession, but as 

 their colours vary on different plants, the seeds should 

 always be saved from those of the brightest colour.
