This elegant and unexpected addition to our flora — ^probably a relic of the 

 last glacial period — was first found at Godhaab in Greenland, afterwards at Melville 

 Island and Spitzbergen, and later in Lapland, Norway, and Sweden, where it is 

 not rare. Mr. Slater referred the plant to a bad state of T. bryoides, and it was 

 not until the appearance of the paper in the Journal of Botany that he found out 

 his mistake. It varies remarkably in size, no doubt in accordance with the variable 

 humidity of the season.
