Geography -, c. Native of Europe, on mountains; 

 plentiful on the tops of mountains in Scotland, but 

 rare on the mountains in the north of England. In 

 North America, it is found wild in the alpine regions 

 of the White Mountains, New Hampshire, and on 

 Grandfather Mountain, Carolina, &c. A procumbent 

 shrub, flowering in April and May, and requiring to 

 be grown in sandy peat, either in a border or in pots, 

 and in an airy situation. The flowers are small, and 

 rose-coloured ; and, according to Pursh, do not appear 

 in Carolina till July. The same author says, " This 

 plant has so much affinity to Z/edum ftiudtolium Ait. 

 (Leiophyllum Ihymifblium Pers.), that I have scarcely 

 been able to persuade myself that they are distinct 

 plants. Comparing specimens of different varieties of the latter, with those 

 of A. procumbens from different countries, in Mr. Lambert's herbarium, I 

 could find no other distinction between both, than that of the Z/edum being 

 an upright little shrub, with decandrous flowers, which are white, whereas the 

 present species has procumbent stems, and pentandrous red flowers. It most 

 certainly ought to be taken from this genus, or else all the rest but this one 

 united with Rhododendron." (Pursh Fl. Amer. Sept., i. p. 155.) This has 

 been done by Mr. David Don, in his new arrangement of the order .Ericaceae, 

 which has been adopted in G. Don's Mill., and which we have followed.
