154 AMERICAN MIDLAND NATURALIST 
softly pubescent beneath, glabrate above. Flowers pale pink, 
3-5 cm. wide, corymbose. Receptacle smooth. Sepals lanceolate 
with 1 or 2 long, linear, glabrate tips, the inner ones entire, the 
outer lobed, white-woolly within and still more on the margins, 
the back of the lower part glandular-hispid. Fruit globular, 1-1.5 
em. in diameter. All the different parts of the plant very crowded. 
This species avoids the open prairie where Kk. heliophila 
reigns, selecting more protected quarters, as thickets, ravines, 
etc. The type was collected in a deep ravine at Butte, Benson 
County, in flower June 25, r911, and in fruit August 28, 1911. 
The flowering season is confined to the latter three weeks of June 
for this and the other species here described, while it lasts for 
R. heliophila from May to September.
