SUPPLEMENT TO THE FLORA OF MONTANA. 81 



Trifoliwn andinum, Nutt. ; Rydberg, Flora, 235. Nutall never 

 collected in Montana and all specimens of his collection so referred 

 are in error. He ascended the Missouri River with the Bradbury 

 Expedition of 1810, which did not go beyond Mercer Co., N. D-3.U-. 

 and accompanied the second Wyeth Expedition of 1834-6, which 

 passed through southern Wyoming, Utah and Idaho, nearly on the 

 line of the present Union Pacific Railway. This specimen doubtless 

 came from the collection of the latter expedition, and is not within 

 our bounds. 



Trifolium brachypus, (Wats.) ; T. longipes brachypus, Wats., Bib. 

 Ind. 264, not T. subcaulcsccns, Gray. Dwarf, 3-7 cm. high, leaves 

 shorter and less acuminate than in T. longipes, Nutt. and peduncles 

 shorter; in alpine situations, near melting snow. Head of Cotton- 

 v/ood Cr., Tobacco Root Range, 9000 ft., Aug. 10, 1902. 



Trifolium latifolium, Greene, Pittonia, 3 :223 ; T. Ion gi folium lati- 

 folinm, Hook. Common in coniferous forests on the river benches 

 in the extreme western part of the state. 



Thompson Falls, Aug. 6, 1901 ; White Pine, Sept. 8, 1904. 



Trifolium macroccphdum, Poir. ; T. megaccphalum, Nutt. Rydberg 

 (Flora, 234) follows Coulter (Man. R. M. Bot. 54), who accepts 

 1'ur-h's (Fl. N. Am. 479) "At the headwaters. of the Missouri", now a 

 part of Montana. The recent revision of the collect ion of tho Lewis 

 & Ckrk i-. \pedition (Proc. Phila. Acid. 1898: 11-49) shows the ori- 

 ginal label of this specimen to -have been "A species of clover near 

 Fockford camp, on high hills,. April 17, 1806", which was the Rock- 

 fort camp at the Dalles of the Columbia (Coues, Lewis and Clark Ex. 

 3 : 95 -953) an d nowhere near our limits. The species has not been 

 found in Montana. Boise, Idaho is the nearest locality yet found for 

 the species. 



Trifolium Montancnsc, Rydberg, Flora, 236. I doubt the possi- 

 bility of separating this from T. Parryi, Gray, as the type of the lat- 

 ter species is the small form, 7-10 cm, high, and there appears to be 

 'little relation between size and leaf-width, though the size and length 

 of the involucral bracts correspond fairly well. Moreover, while 

 our Montana plants are usually small with leaflets broader than in 

 the type of Parrvi, the narrow leaved forms occur, as on Mt. Hya- 

 li'te, along with the other form and the larger bracted forms are found, 

 as on the Spanish Peaks, having the low size and wid^.-r leaf.
