DESCRIPTION OF THE EHODODENDRON. 61 



Variety Nobleanum has bright scarlet flowers, 

 and is a very beautiful kind. There are also sub- 

 varieties with rose and pink flowers ; but that called 

 Noblearmm superbum is the best. 



Rhododendeon chetsanthum. 



Tliis pretty little species is a native of Siberia and 

 other extreme northern countries : it is also found 

 in the Caucasus Mountains. It is a low shrub, never 

 exceeding one foot in height, with evergreen leaves, 

 and large, irregular, yellow flowers. 



While perfectly hardy, it is difficult to cultivate, 

 the heat of summer probably aflecting it unfavorably. 

 It is rarely found in cultivation. Figured in Wood. 

 Med. 2, 103 ; and in Steph. Med. 2, 80. 



Rhododendeon punctatum. 



This pretty species, although a native of Carolina 

 and Georgia, generally stands the winter with us ; 

 although the foliage is usually somewhat disfigured, 

 and the flower-buds are killed if the mercury falls 

 much below zero. The foliage is dark green, covered 

 below with rusty dots, whence the name ; the flow- 

 ers are small, pink, very pretty, but not especially 

 showy. The habit of the plant is straggling. It is 

 worth growing in a collection, but is only interesting 

 for variety. Seedlings vary much in shade and 

 markings of the flowers.
