could be found in the way of plants. In this way we moved’ 
up the river. It did not take loag to discover that we were 
in a flora differing from that of the prairie almost as much as. 
if it had been on the other side of a continent. Viola del- 
phinifolia, Callirrhoe alcewoides, Oxytropis Lamberti, andi 
Senecio aureus, var. Balsamite occurred occasionally, while 
Sisyrinchium mucronatum, which was somewhat rare on the 
prairie, almost covered the river bottom. Everything else 
was new. In the water of a slough we found Ranunculus: 
multitidus, Erigeron Philadelphicus. Viola palmata, var. 
cucullata, and Lithospermum angustifolium were occasionally 
found, while Salix longifolia lined the river bank in places. 
Among the best ‘‘ finds’? made were Crepis runcinata' and 
Plantago eriopoda, both of which seem to belong farther 
_ west, at least they have not been found east of Colorado. 
Cypripedium parviflorum, which is said to be quite rare im 
this state, was very abundant in one place. 
At one point along the river several acres of the bottorm 
were found very thickly dotted with Cypripedium candidum. 
Local botanists claim that this is the only place in the state- 
where it is found. Perhaps this is true, as it is no doubt very 
rare. The plant, however, whose presence here surprised’ 
me most, was Lysimachia thyrsiflora. This is, or has always:
