33 Allium sp. 



Pursh describes Allium angulosum I, p. 223, as '• on the banks of the Mis- 

 souri, M. Lewis, July" The specimen in this collection is so eaten that 

 neither flowers nor roots are left. As these remains are ticketed " on the 

 waters of the Kooskooskee, April 30, 1806," it is probably of another species 

 overlooked by Pursh, and not angulosum. So far as the leaves indicate, it 

 may be A. reliculatum. 



34 Described by Pur^h as Brodicea grandiflora Fl. I, p. 223. " Hyacinth of 

 Colorado Plains, April 20, 1806." Pursh says : " on the plains of the Colum- 

 bia and Missouri Rivers, M. Lewis, April and May. This elegant bulbous 

 plant was called by M. Lewis rightly, Missouri Hyacinth." In the Journal of 

 the expedition it is noted under date of April 16th, then at Rockfort camp, 

 " a species of Hyacinth, a native of this place, bloomed to-day. It was not in 

 bloom yesterday."
