Ranunculus Cymbalaria Pursh. Darby, Browning, Upper Marias Pass, 

 Missoula, Dayton, Hot Springs, St. Ignatius Mission. 



Myosurus minimus L. Ronan. 



Trautvetteria grandis Nutt. Alta. » 



Thalictrum sparsiflorum Turcz. Alta. 



Thalictrum occidentale Gray. Common in open woods and mountain sides 

 from Evaro northward. T. venulosum Trelease seems to be only a form of 

 this. 



Thalictrum purpurascens L. Ravalli, Ronan, Lolo. Gotten also at Plains 

 by MacDougal. 



Anemone parviflora Mx. MacDougal Peak, Lambert Valley, Blackfoot 

 Glacier. 



Anemone Drummondii Wat. Bt. Cal. 2 424 (1880). Drummond's Anemone. 

 Elrod Peak (Elrod), and Mission Mts. (Elrod). Alpine. This little under- 

 stood plant has alternately been referred to Tetonensis and allied species. A 

 detailed description of it as it is may clear up some doubts. Flowers 35 mm. 

 wide. Sepals fully 15 mm. long, oval, blue externally and white within, vil- 

 lous. Flowering peduncle 2.5-7.5 cm. long, 10 cm. long in fruit, stout, erect. 

 Involucre with sliort and broad base, 7.5-15 cm. long, about like the leaves 

 but large. Flowers single. Scape stout, almost none in flower, short in 

 fruit. Plants caespitose from a thick root after the fashion of A. Hudsoniana. 

 Leaves leathery, thrice ternate, with cuneate-oblanceolate lobes 9-13 mm. 

 long and apiculate, nearly smooth. Styles filiform, 2.5 mm. long. Akenes 

 long-woolly except in a narrow line on the back where it is short-hairy. 

 Flowers about twice the size of A. Hudsoniana. Heads ovate 15 mm. long. 

 Sperry Glacier. Lambert Valley, McDonald Lake, Mission Mts. 



Anemone patens var. Nuttalliana (Spreng) Gray. Rexford, Garrison, Ra- 

 valli, Missoula (Elrod). 



Anemone occidentalis Wat. Very common on MacDougal Peak and Black- 

 foot Glacier and Lambert Valley. Alpine. 



Clematis hirsutissima Pursh C. Douglasii Hook. Evaro. 



Clematis verticillaris var. Columbiana (Nutt.) Gray. Frequent from Alta 

 to Blackfoot Glacier. 



Coptis occidentalis (Nutt.) T. & G. Alta on rotten logs in deep shade. 



Trollius laxus Salisb. Alta, McDonald Lake, Mission Mts., Sperry Glacier, 

 abundant at Gunsight Pass and Lake. 



Aquilegia flavescens Wat. Bot. King 10 (1871). Tellow Columbine. Com- 

 mon in open, wet and springy but well drained places and rarely on slopes, 

 alpine and subalpine, even to the top of MacDougal Peak. Sometimes pink, 

 but not differing otherwise. Piper, Fl. Wash, 279, states that this species 

 freely intergrades with A. formosa. The writer has seen no such inter- 

 grades, but they are to be exjiected as this species, A. formosa, and A. 

 truncata, ar manifestly recent offshoots of A. Canadensis, from which they 

 hardly deserve separation. Robinson has also fallen into the error of Watson 

 (Bot. King 10) in the Synoptical Flora, 43, where he speaks of the "alpine 

 smaller flowered form" as regarded as distinct by me. Watson's smaller 

 flowered form, as shown by his own specimens, was not alpine, but was got 

 low down in City Creek Canon near Salt Lake City, and is a well defined 

 species which I have many times collected in the type locality. Watson's ref- 

 erence to its being alpine is evidently an error which Robinson has copied. 

 The plant described by Watson looks more like a hybrid between A. coerulea 

 and the "small flowered form" in Utah, where Watson got it. It is always 

 alpine. But identically the same thing grows throughout Wyoming, Idaho 

 and Montana in places where A. coerulea is not found and therefore cannot 

 be a hybrid. This species can be instantly separated from all forms of A. 

 formosa that I have seen by the short and hooked spurs, but in the north 

 country it is sometimes with red sepals. McDonald Peak, also Columbia 

 Falls (Williams). MacDougal Peak (Elrod, MacDougal and Umbach). Hall's
