ADDITIONS TO THE FLORA OF COLORADO. I. 
BY ALICE EASTWOOD. 
In making out this list, Coulter’s “‘ Manual of Rocky Mountain 
Botany” has been taken asa basis. The additions include a con- | 
siderable number found in that book, but not credited to Colorado. 
Others which I supposed I had first discovered had been previously 
reported by Mr. Brandegee in his ‘‘ Flora of Southwestern Colo- 
rado,”’ and are included in this list by his permission. 
I was at Grand Junction, near the Utah boundary, for a week in 
the middle of May, and again for three days in August. It proved 
to be a field rich in new forms. The latter part of May and the first 
half of June was spent in Southwestern Colorado at Durango and 
Mancos, and some very interesting Umbelliferee were obtained there. 
The entire month of July was spent in Routt County, at Egeria Park 
and Steamboat Springs, and at these places about three hundred 
and fifty species were recorded—not including Gramineze, Juncacese 
and Cyperaceze, the many species of these three orders being yet 
undetermined. The final collections of the season were made dur- 
ing a few days in the month of August, at Crested Butte, in the Elk 
Mountains. 5 
It will be plain from the foregoing, that the many additions made to 
our flora were secured in consequence of collecting in little visited lo- - 
calities, or at earlier seasons than the visits made by other botanists. 
I wish to acknowledge my debt to Mr. J. N. Rose for determina- 
tions of Umbelliferze, to Dr. Sereno Watson for valuable assistance, — 
and to Mr. T. S. Brandegee for needed advice and help.
