ALLIUM SIBIRICUM L. Mant. 562. 1767. (Aaiun/ Schaenoprasum it L. Sp. Pl. 301. 1753. Allium Schaenoprasum Authors.) This has generally been confused with Allium Schaenoprasum, but it is evidently a good species. It is much taller than that plant, being generally 5-6 dm. high, has only one basal leaf and generally several stem-leaves, these thick, about 5 mm. in di
ameter, and broader perianth-segments. Allium Schaenoprasum is only 2-3 dm. high, and its base is surrounded by many narrow leaves.
In rocky places, Sweet Grass Canon, Crazy Mountains. (Alt. 7000 ft., no 349.) It has also been collected at Deer Lodge, July 9, 1895, by myself (no. 2601).
