It is very doubtful whether these specimens are actually Saxifraga 

 hieracifolia W. and K. Owing to conditions incident to the World War it 

 has been impossible to obtain authentic material from Hungary (the type 

 locality) for comparison. The specimens at hand are very different, how- 

 ever, from a Norwegian specimen in the Herbarium of the University of 

 Minnesota. The latter has broad elliptic-ovate leaves on short petioles, and 

 possesses a distinctly raised gland which persist sas a flange around the 

 carpels, a condition not found in the Alaskan specimens. In the characters 

 of the petals, sepals, and hairs, however, the two plants are similar. The 

 gland of the Alaskan specimens is conspicuously depressed and smooth in 

 the early stages, and the flowers are characteristically stellate. It was the 

 form of the petals no doubt that led Hooker (16) to infer that the American 

 plant, to quote his words, "appears exactly intermediate between S. peiin- 

 sylvanica and 5". nivalis, more allied, however, to the former" but its deep 

 receptacle, flat, appressed, discoid gland, and stout erect follicles indicate 

 no very close relationship to either, petal- form in this case furnishing no 

 criterion of relationship. Furthermore, the American specimens do not
