Dr. J. Lunell, of Leeds, N. D., an enthusiastic student of the northwest | 
flora, communicated the specimens tome. I have pleasure in naming the species. 
in his honor. He writes: ‘‘It grows on high barren hills among rocks. Its

at Butte, Benson Co., N. D., June 13, 1905.

at sumnut: all the leaves erect, quite entire, thick or subcoriaceous, 
acute or apiculate; radical leaves oblong, 2-3°™ long, tapering 10 
a sleader petiole as long as the blade; cauline leaves very numerous, 
alrsost imbricated, linear-lanceolate, 1 5-25*"™ long: racemes short, 
. cfowded: sepals elliptic, scarious margined, half as long as the |
