(Bitter Root) Mountains" to the Coeur d'Alene River and wintered at 
the Chamokane Mission, located on Chamokane Creek about 10 miles from 
its junctions with the Coeur d'Alene River. During the summer of 18h) 
Geyer made trips northwestward as far as Fort Colville, southward to 
the Palouse River, Nez Perce, and the Lapwai Mission. Some of his most 
important collections were made in the Spring in the vicinity of Lake 
Coeur d'Alene and Skitsoe Lake. Late in the Season of the same year, 
he botanized in the Craig Mountains, and, passing around the Blue 
Mountains, reached Fort Walla Walla, from whence he descended the 
Columbia, bound for Fort Vancouver and England. Geyer wrote of Camassia 
prairies under the designation "Ganasa prairies" and tells of his hungry 
horse having browsed upon "Taxod ium sempervirens" (p. 205). His col- 
lections were all numbered and can be fairly closely placed by his nar- 
rative (Hookers London Journ. Bot. 9: 201-208, 285-310, 509-52. 1846). 
There is evidence from his detection of such infrequent species as Orc- 
banche pinorum that Geyer was a sharp-eyed collector. He showed an in- 
terest in placing manuscript names upon his collections before submit- 
ting them to Hooker; many of these names were employed by Hooker in pub- 
lishing his species. 
At the time of Geyer's visit to the Lapwai Mission the Ameri- 
can missionary, Rev. Henry Spalding, was in residence there. Spalding 
sent a number of plants to Asa Gray. Astragalus Spaldingii, Gray, con- 
memorates this association and Spalding's interest in the native plants. 
Piper (Contrib. U. S. Natl. Herb. 11: 16) has recorded the best avail- 
able notes on Spalding.
