SI LENE REPENS Patrin, in Pers. Syn. i : Soo. 1805.
This Siberian species has been collected in Montana at the following stations: Spanish Basin, July II, 1896, Flodman, no. 41 2 ; Mystic Lake, Bozeman Cafion, 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. repens 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 Steliana a'ichotoma in Montana some years ago."
