Henderson, Junius. Made occasional collections in northern Colorado from 1895 

 to date. These in his private herbarium except a few in the University of Colorado 

 herbarium. Address: Boulder, Colo. 



Holm, Theodor. Collected in Colorado chiefly alpine plants in 1896 and 1899. The 

 collections were made for comparison with the arctic flora with which Dr. Holm had 

 become familiar in three expeditions with which he was connected (1882-83, 1884, 

 1886). Following are some of the places visited in Colorado: Clear Creek Canyon, 

 Estes Park, Long's Peak, James Peak, Leadville, Twin Lakes, Mt. Massive, Gray's 

 Peak, Torrey's Peak, Mt. Elbert, Mt. Kelso, Pike's Peak. The specimens collected 

 are chiefly in Dr. Holm's private herbarium at Brookland, D. C, but some duplicates 

 were sent to the Field Columbian Museum, Chicago, and others to the Royal Swedish 

 Academy, Stockholm.
