 side of Smith Sound.

The Ellesmereland specimens are, as a rule, well grown and robust, 

 attaining a height of 15 cm., with many flowering, as well as sterile, 

 stems from the rhizome. The corolla is always shorter than the fully 

 developed fruit, sometimes also than the ovary. The relative length 

 of corolla and sepals is very variable ; specimens with a corolla of the 

 length of the sepals, and even shorter, are to be found, as well as such as 

 have it longer, in some cases nearly three times as long. These seem 

 to come near to the form that has been called G. Gieseckeana, (Vest), 

 which, according to Decandolle, Monogr. Camp., p. 339, and Prodr., 7, 

 p. 482, is distinguished "corolla calyce quadruplo longiore". According 

 to the latest treatment of the genus Campanula, Witasek, Beitr. Kenntn. 

 Camp., p. 50 — 53, however, this "name is not meant for any form of C. uni- 

 flora, but for an arctic species, allied to C. rotundifolia, or a sub- 

 species of the latter, comprising the arctic forms that are conveyed to 

 that specie^. It seems also probable, that Vest originally had such a 

 form in view. 



In the Ellesmereland- and in most of the Greenland-specimens, the 

 lobes of the corolla are glabrous. 



The flowering time seems to be very short, about a fortnight, after 

 the middle of July only solitary, belated flowers are to be found among 

 the well-developed ripe or half-ripe fruits. 



Grows on grassy ledges and slopes, and is therefore, as it seems, 

 restricted to the archaean districts of the eastern and south-eastern 

 coast, probably it is entirely missing in the lime and sandstone territory
