Macbride and Payson — Plants from Idaho 61 
RANUNCULUS INAMOENUS Greene. This species, frequent in the 
central Rocky Mountains is represented now from Cape Horn, 
Custer County, Idaho by our number 3621. 
RANUNCULUS INTERTEXTUS Greene, Ottawa Nat. xvi. 33 (1902). 
Our number 3372 from Squaw Creek, Custer County, Idaho well 
represents this species which is R. natans C. A. Meyer of the 
Coulter-Nelson Manual of Rocky Mt. Botany. Meyer’s species, 
however, is Asian and if we may judge from the plate of it in Ledeb. 
Ic. 114, Greene was quite justified in proposing the plant of North 
America as a distinct species. R. intertextus does not appear to 
have been collected before in Idaho although it occurs occasionally 
in Colorado, Wyoming, and Spokane County, Washington. 
CLEMATIS ORIENTALIS L. C. cruz-flava Ckll. Science n. ser. x. 
898 (1899) and C. aurea Nels. & Macbr. Bot. Gaz. lv. 373 (1913) 
should be referred to this species. Wooton and Standley in their 
Flora of New Mexico remark that ‘“‘ C. orientalis is reported to have 
escaped near Las Vegas but...... it is not likely to become a per- 
manent part of our flora.” This observation may be true as regards 
New Mexico but the species is not only well established but 
spreading in the vicinity of Challis, Idaho. It was collected there 
first in 1909 and this year (1916) it was noticeably more common. 
It clambers over wild thickets along streams and appears to be 
native. Macoun secured it in 1901 at Port Colburne, Ontario and 
his label bears the inscription ‘ well established.”” We wish to 
express our indebtedness to Mrs. Earl J. Michael of Challis who 
kindly prepared for us the neatly pressed flowers and fruits which 
supplement our foliage specimens gathered July 21. The collection 
is numbere 6 
QUILEGIA FLAVESCENS Wats., var. Miniana, var. nov., sepala 
albido-rubra vel ad colorem salmonis accedens. — IpaHo: stream 
bank, Challis Creek, Custer Co., July 19, 1916, M7 acbride & Payson, 
no. 3 
Blaine Co., Aug. 13, no. 3751; also along alpine brook, Sawtooth 
Peaks, Aug. 9, no. 3692. 
It has been recognized for some time that A. flavescens and A. 
formosa merge in the territory where their ranges join. As a result 
there exist many intermediate forms which cannot be definitely 
referred to either of these species. One such state has been evolved 
in central Idaho and there in many localities entirely replaces the
