478 Rydberg: Studies on the Rocky Mountain flora 



pubescent; lobes lanceolate, acute, fully equaling the tube; 

 corolla 10-12 mm. long, open-campanulate, violet with yellowish 

 base; lobes rounded-truncate at the apex; stamens two thirds 

 to three fourths as long as style and slightly longer than the 

 corolla. 



This resembles P. scopulinum Greene in habit, but is a larger 

 plant with much larger flowers. It grows in the mountains of 

 Idaho and Washington at an altitude of 1,500-2,000 m.

Polemonium intermedium (Brand) Rydb. sp. nov. 

 Polemoniiim occidentale intermedium Brand, Pflanzenreich 4^^°: 



33- 1907- 



This I think is well worth specific rank. It is confined to the 

 Columbia River region of Idaho, Washington, and British 

 Columbia. 



Dr. Brand regarded Polemonium speciosum Rydb. as a good 

 species. Professor Nelson on the other hand makes it a variety 

 of P. mellitum (A. Gray) A. Nels., which is evidently erroneous. 

 If it should be made a variety of any of the verticillate species 

 of Polemonium, it should have been of P. viscosum Nutt. or rather 

 of P. Grayanum Rydb., which species Professor Nelson does 

 not regard as distinct. P. speciosum has a short blue corolla 

 and subcapitate inflorescence.

The Miltitzia section of Emmenanthe of Gray's Synoptical
