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. 
Polemonium occidentale intermedium Brand, Pflanzenreich 42°: 
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.

Miltitzia foliosa (Jones) Rydb. 
Emmenanthe foliosa M. E. Jones, Zoe 4: 278. 1893. 
The Miltitzia section of Emmenanthe of Gray’s Synoptical 
Flora, I think is generically distinct from Emmenanthe proper,
