SUPPLEMENT TO THE FLORA OF MONTANA. 55 



Myosurus apetalus, Gray. In the bed of a dry pond. Gardiner, 

 July 4, 1899. 



Ranunculus acriformis, Gray. Monida, June 26, 1902 ; Coppero- 

 polis, Meagher Co., July 23, 1902; Sunset, June 17, 1896, Mrs E. 

 W. Scheuber. 



Ranunculus alpeophilus, A. Nelson is R. inamoenus, Greene. Rvd- 

 berg (Flora, 164) seems to have taken a form near his own sixicola 

 for Nelson's species. 



Ranunculus cardiophyllus, Rydberg, Flora, 165, is R. inamoenus, 

 Greene. 



Ranunculus circinatus, Sibth. In ditches and slow streams, fre- 

 quent. Gallatin River, July 27, 1898; Big Coulee Cr., Sweet GrioS 

 Co., June 15, 1892; Broadwater, Helena, June 14, 1898, E. N. 

 Brandegee. 



Ranunculus Cymbalaria alpinus, Hook. Near the Continental 

 Divide, Empire, Aug. 1902, Owen Byrnes. 



Ranunculus ellipticus, Greene. See R. glaberrimus below. 



Ranunculus erenwgenes, Greene. The characters given by 

 Greene (Erythea, 4: 121) for this species will hold 

 equally well for European and Asiatic specimens of 

 A 5 , sceleratus, L., and even the rank, fleshy, fistulus, large- 

 flowered form, which he regards as the typical European sceleratus, 

 occurs occasionally here in situations which preclude its' introduc- 

 tion. All our specimens come under R. sceleratus, L. 



Ranunculus Flammula intermedius, Hook. In wet places, in- 

 frequent. Flathead Lake, July 23, 1900; Belton, Aug. 19, 1902; 

 Columbia Falls, June 25, 1894, R. S. "Williams; Thompson Falls, 

 Aug. 6, 1901; Midvale, July i, 1903, L. M. Umbach. 



, Ranunculus Flammula varians, n. var. 



Stems filiform, 10-20 cm. long, creeping and root- 

 ing at the nodes; leaves ovate, rarely oval, 5-12 mm. long, 

 on petioles nearly twice that length; petals 4 mm. long: 

 otherwise as in R. Flammula reptans, Gray, from which it differs main- 

 ly in its ovate leaves. Crow Creek, Mission Mts., Aug., 1897, M. J. 

 Elrod, 234. A similar but larger form with leaves 1-2 cm. long and 

 8-12 mm. wide, collected in wet places at Lake McDonald, Aug. 

 30, 1903, appears to be the same verging toward the variety intermedi- 

 us, Hook.
