MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. 235 



Montana: Missoula, 1898, Williams iS: Griffith. 



* Trifolium Rydbergii Greene, Pittonia, 3: 222. 



The Wild White Clover of Montana is also one of the best native 

 forage plants, only surpassed in value by some of the grasses. It 

 is a rather common plant, growing in wet meadows. It is a near 

 relative of T. longipes, but it is taller, with larger heads and the 

 flowers reflexed in fruit. In meadows, at an altitude of 2000-3000 m.

Sometimes it is lower, only about 2 dm. high, with shorter pe- 

 duncles. Such specimens I have seen from the following localities :

 R. M. 55]. 

 ( ?) Montana : Niittall. 



* Trifolium Haydeni Porter in Hayden, Rep. 1871 : 480. 



Common in the mountain regions, on the higher mountains as 

 well as in the valleys, at an altitude of 2000-2700 m. Dr. Watson 

 included it in T. Kingii, with which it has little relationship. It 

 is a cespitose plant, resembling somewhat T. latifoliuni Greene 

 ( T. longipes latijblium) in leaves and flower, but is perfectly dis- 

 tinct. The leaflets are broadly obovate and sharply denticulate ; the 

 flowers white or slightly pinkish on slender, but short, reflexed pedi- 

 cels. Mountain sides and along brooks, at an altitude of 2000-3000 m.
