Helia^nthemum canariense, Canary Sun-rose, si low 

 green-house shrub, introduced from the Canaries in 1790, 

 and flowering in June and July, 



H. glutindsum, clammy Sun-rose, a low frame-shrub, a 

 native of the South of Europe, introduced in 1790, and 

 flowering from May to September. 



These plants are of the easiest culture, and the H. 

 formdsum and a few other species look well when in flower. 

 The flower has this peculiarity, that it only opens during 

 clear sunshine^, and therefore in our climate it often opens 

 and shuts many times a day. The soil which suits them 

 best is a sandy loam with a little peat or leaf-mould : most 

 of them ripen seeds, from which, or from ripened cuttings 

 under a hand-glass, they may be readily increased.
