Ural. Probably it goes over, everywhere to the southward, into typical 

 P. rotundifoUa, which has a wide distribution in the three continents. 

 In Europe the var. grandiflora is not found.

A plant which, even if it is not at all rare in the archaean districts, 

 nevertheless may during many summers not reach to flowering and 

 still less to the development of ripe fruit. During the whole summer 

 of 1899 I could only find sterile specimens of it, except at Twin Glacier 

 Valley, where young flower-buds were seen (July 5th). In the summer 

 of 1900, which was rather warm, I saw it flowering richly at several 

 points, and already at the beginning of August, the fruit was nearly 

 ripe in the neighbourhood of our anchorage in the Harbour Fjord. 

 Probably, however, it had time enough to flower and to ripen its cap- 

 sules even in the preceding summer, at least in the interior of Hayes 

 Sound, to which region I had no opportunity of going after June 12th. 

 But in cold summers, such as 1901, it will probably not even reach to 

 flowering, at least not to development of ripe seed. Kjellman also says 

 (As. Beringss. Fan., p. 529), that this species in certain parts of the 

 Asiatic north coast, must probably be reduced chiefly to vegetative pro- 

 pagation. For this also it is well provided, the more so, as it grows 

 chiefly on loose, gravelly soil, with scarce vegetation, where its strong 

 rhizome can creep far round about. The severe drying out, however, to 

 which it is exposed in such places, brings with it the risk, that it may 

 not be able, even in a year that is otherwise favorable, to ripen its 

 fruit, as the capsules will dry up already at an early stage.
