Notes on the Flora of High Altitudes in Custer County, Colorado. 
By T. D. A. COCKERELL. 
During the last few years, while residing in Wet Mountain 
Valley, I have endeavored, as opportunity permitted, to ascertain 
something of the flora and fauna of the high altitudes in the 
Sangre de Cristo Range. The present notes are the results of 
these investigations, so far as regards the flora of this region. 
The species enumerated were collected on the eastern slope, in 
Custer County, and so far as I could guess at the altitudes, 
(having no aneroid), all are from 10,000 feet above sea 
level or upwards. These records, which all relate to the plants 
of the vicinity of Gibb’s Peak, ( miscalled Gibson Peak on 
the maps), will give a very fair idea of the general features 
of the flora, but it is to be remembered that the cryptogamia, 
grasses, Carices, etc., were almost entirely neglected. There isa 
great opportunity for some future student of these groups in this 
district. 
Most of the species from the Lakes of the Clouds, (11,000 
feet or over), were collected by Mrs. M. E. Cusack, and many 
of the new forms enumerated are in her herbarium. I am great- 
ly indebted to Dr. George Vasey, Dr. J. M. Coulter, Mr. F. W. 
Anderson, and Mr. J. B. Ellis, for the identification of some of’ 
the species. 
RANUNCULACE&, About the Lakes of the Clouds are found 
Ranunculus abortivus and R. pygmaeus, and Trollius laxus. 
In the timber one meets with an abundance of Aguilegia ceru- 
lea, a plant of great beauty and interest. Near the lakes, (when-
