12 Muhlenbergia, Volume 3 
wide at base, 2mm. wide across the top, the edges somewhat in- 
rolled: stamens exserted 2mm. from the unreflexed calyx, an- 
thers oblong, 1 mm. long: style commonly a little exceeding the 
stamens, 2-parted dewn almost to the petals, densely villous for 
nearly its entire length: ovary glabrous. 
The type, in my herbarium, was collected somewhere in 
Washington in 1897 by Mr. W. N. Suksdorf, to whom I take 
pleasure in dedicating the species. It is part of a consignment 
of several species collected for me in quantity by Mr. Suksdorf 
and laid aside for the past ten years, the record which accom-< 
panied the plants apparently lost. The plant is no doubt from 
the eastern slope of the Cascades near the Columbia river in 
Klickitat county, as I think Mr. Suksdorf resided at White Sal- 
mon at that time. 
It is related to R. divaricatum, but differs from that species 
in the absence of “bristle shaped prickles” on the young 
branches; in having only a single small straight ascending spine 
instead of ‘one or three large, strong, deflexed prickles under 
each bud;” the leaves are not “smooth and veiny;” the calyx 
is hardly “bell-shaped,” and the petals are narrower with a more 
claw-like base than those of 2X. divaricatum, which apparently 
is restricted to the wet country on the west side of the Cascade 
‘mountains. ,
