qi) canoes were built in October, 1905 for the journey which ultimately 
took them down the Columbia. During the course of this journey Lewis 
had made botanical collections and referred to many of these in his 
narrative. Unfortunately, these collections, made on the more leis- 
urely westward trek,were lost in the Columbia by wreck of one of the’ 
canoesy2nd the identity of many of the plants referred to by Lewis 
must consequently remain in doubt. Upon the return Journey, collec- 
tions were made to replace those which were lost, numbering about 150 
species, but they were principally late season species, taken chiefly 
east of our limits. However, a camp was established near the present 
site of the town of Kamiah, in May and June, 1806, and collections 
1 
were made there and at "Quamash Flats," now known as Weippe meadows, 
near the town of Weippe (pronounced We-ipe). It is these which form 
Ww the classical nucleus of the Idaho flora and include such species as 
Scutellaria angustifolia, from Camp Croounnish, and Camassia quamash an 
Polygonum bistortoides, from Quamash Flats. All may be examined today 
in the herbarium of the Philadelphia Academy of Natural Sciences. 
In addition to the manuscript notes of Lewis which appear on 
some of the specimens, there are also apnended notes by Frederich 
Pursh (1774-1620)* who described and figured some of the species in 
his Flora Americae boreali-sextentrionalis (1012). During 1897, B. 1. 
Robinson and J. M. Greenman studied the Lewis plants and annotated 
* Pursh, A German by birth, was christened Friedrich Traugott Pursch.
