This elegant little species is a native of the whole of northern and 
central Europe, chiefly in alpine and subalpine situations, though 
Mr. Newman mentions (Hist. 244) its occurrence at Grasse, in the 
south of France, where the climate is mild, and the altitude but 
little above the sea-level. It extends from Lapland, Finland, 
Norway, and Sweden, to Great Britain, France, Switzerland, Bel- 
gium, Germany, Bohemia, Dalmatia, Croatia, Italy, Spain, and 
Greece, occurring also in Tauria. In Asia, it is found in India: 
Kumaon, and in Eastern Siberia; and it is further met with in the 
Island of Sitka, whence it. extends to the Rocky Mountains of 
North-West America. A South American plant, found in the 
mountains of Peru and Colombia, the A. fragile of Presl, is closely 
allied to our British species, but is proliferous on the stipites. 
“ Were it not for the curious little viviparous bulbilli seen upon the 
stipes," observes Sir W. J. Hooker,* “it would be difficult to say in
