SiLENE REPENS Patrin, in Pers. Syn. i : 500. 1805. 



Tliis Siberian species has been collected in Montana at the 

 following stations: Spanish Basin, July ii, 1896, Flodman, no. 

 412; Mystic Lake, Bozeman Caiion, July 24, 1895, Rydberg, no. 

 2635, As far as I can find, there is no reference in print regard- 

 ing its occurrence in America. Dr. B. L. Robinson, to whom the 

 specimens were sent for identification and who has determined it 

 as well as the next following species, writes: 



" Your specimens of S. repeiis are very interesting. I have 

 seen specimens from Alaska, but never before from other parts of 

 North America. I have no doubt, however, of the identity of 

 your plants with the real Asiatic plant, having just made careful 

 dissections of the two alongside of each other. However, the 

 matter of distribution is not so surprising after the discovery of 

 Stdlana dicJiotoma in Montana some years ago."

Stdlana Edzuardstt R. Br., Parry's ist Voy. 271. 



This is, I think, the first time this variety is reported from 

 within the United States. Only a few specimens were collected, 

 at an altitude of 8000 feet on Spanish Peaks, July 14, 1896, Flod- 

 man, no. 429. 



Akenaria subcongesta (Wats.) 



Arenana Fendle^i subcongesta Wats. Bot. King's Exp. 40. 1871, 

 A. congesta subcongesta Wats. Bot. Cal. i : 69. 1876. 

 Arenaria congesta subcongesta as generally understood, I think, 

 contains more than one distinct type ; at least, that is the case
