NAT. ORDER. — ERICE.E. 13 



kinds of Rlwdodendron may be propagated freely by cutting's taken 

 off from young wood, and planted in sand, placing a bell-glass over 

 them. There are now in the gardens a great many hybrid kinds of 

 Rhododendron, and they are still increasing in number ; some of which 

 outvie the species in splendor. The species natives of Nipal, China 

 and Japan, in mild winters, would probably succeed in the open air, 

 but they will not survive a severe winter without protection ; they are 

 therefore best kept in pots, and placed among other green-house or 

 frame plants. ItJiododaulron arhoreum and Rhododendron album are 

 among the most showy of the species, and are well adapted for con- 

 servatories, or to be placed in large tubs in the green-house. Young 

 cuttings of the tender kinds, if torn off close to the stem, and planted 

 in a pot of sand, will strike root readily : the pot should be plunged in 

 peat under a hand-glass.
