Parnassia MOXTANENSis, Femald and Rydb, N.A. Fl.XXII, 79. 



P. paUistris, Macoun, Cat. Can. Plants, I, 159 in part. 



Easily separated from P. palustris, with which it w-as 

 formerlv included, by its shorter petals and conspicuous 

 hypanthium. P. palustris has petals nearly twice as long as 

 the sepals, in P. moutanensis they barely exceed the sepals; 

 the hypanthium is inconspicuous in the former and fully half 

 as long as the sepals in the latter. P. palustris has usually 9-15 

 staminodia, P. montanensis 7-9. Our specimens are all from the 

 Rockv Mountains and were collected at Laggan (No. 65,294), 

 Cascade (No. 8,580), Wapta Lake (No. 65,295), Crow Nest Pass 

 (No. 20,170) and Moose Mountain, Elbow River (No. 20,171). 

 The Moose Moiintain specimens were collected at an altitude of 

 6,500 feet.

Though perhaps to be considered only a variety of R. glabra, 

 R. occidentalis is distinguished from it by its longer, usually 

 less spreading leaves, usually larger number of leaflets, shorter 

 calvx and linear-oblong anthers. All our specimens arc from 

 west 'of the Selkirk -Mountains. Deer Park, Columbia River,
