POLEMONIUM MONTROSENSE A. Nelson, Proc. Biol. vScjc. Wash. 

 18: 174. 1905. 

 Since the publication of Polemoniiim nuintrosense b)- Pro- 

 fessor Nelson from specimens sent to him by us, we have had 

 ample opportunity to study the plant in its natural habitat, and 

 also to take the photograph which we use in our illustratton. 

 The plants sent to Professor Nelson were about one-fourth the 

 size of those here shown, and represent the typical form of the 

 species as it grows fully exposed to the sun and wind, while our 

 illustration represents the plant as it occurs in good soil and 

 well shaded by the rocks. In the former case the orbicular leaf- 

 lets of the radical leaves are very conspicuous and crowded.
