plant, with narrow, glaucous-green leaves and beauti- 

 ful white flowers tipped with rosy-red. 



It is a native of cold bogs of both continents, 

 extending into high latitudes, and is therefore per- 

 fectly hardy. 



The difficulty in cultivation is to keep it cool and 

 damp. With us it grows and flowers beautifully in 

 the shady part of a Rhododendron-bed on a northern 

 hillside. 



There are many varieties, differing in size of plant 

 and color of flower : all thrive under the same treat- 

 ment, and are desirable.

A. ROSMAEINIFOLIA 



Much resembles the last, and may be only a 

 variety. 



The plant found in catalogues as Andromeda 

 formosa is a native of Nepal, and tender with us. 

 The flowers are rosy-white, in drooping clusters, and 

 very showy. Also called Pieris formosa. 



Andromeda mariana. 



This species, also known as Lyonia, is a hardy 

 plant, with deciduous foliage and large, white flowers. 

 It is well worth growing, and does well in any good 

 loamy soil. 



Figured in Bot. Mag. t. 1597.
