COLORADO PLANTS. 
BY ISAAC C. MARTINDALE, 
EALIZING the fact that all discoveries or observations, unless 
brought to the attention of the people in some way, cannot 
be expected to be of much advantage to them, I have prepared 
this article in the belief that some lover of flowers, who has been 
or may be traveling over the same route taken by myself, may 
find in it a help or an assistance in the prosecution of the study 
of botany, or in naming the specimens collected by the way. 
The list of plants hereto appended is of the specimens collected 
while on an excursion of the members of the American Associa- 
tion for the Advancement of Science after the adjournment of 
the St. Louis meeting in 1878, and during the time of the meet- 
ing at St. Louis on the excursions around the city, chiefly near 
Cahokia, Illinois. The route taken from St. Louis was westward 
to Kansas city, thence by the Kansas Pacific R. R. to Denver, 
thence southward to Colorado Springs, Manitou, Garden of the 
Gods, Queens Cañon, Glen Eyrie and Pike’s Peak, making the 
ascent by way of Engelmann’s Cañon ; continuing the journey 
from Colorado Springs southward to Alamosa and returning to 
Denver ; thence by way of Clear Creek Cañon to Idaho Springs, 
Georgetown, Central city and Blackhawk, also visiting Boulder 
Cañon as far as the Falls. 
The rapidity of travel and consequent difficulty in taking 
Proper care of the specimens prevented a larger collection being 
made, yet it is believed it embraces the greater part of the plants 
that may be found on the line of the route traveled. About forty 
persons participated in the excursion, several of whom were 
interested in the botany of the region and made collections of 
plants; I have been favored with an examination of these, and 
think the list includes all or nearly all that were obtained. Mr. 
Thomas Meehan, of Germantown, State Botanist of Pennsylvania, 
was one of the excursion party, and having visited Colorado on 
two former occasions, was well informed about the plants, and 
tendered valuable service. Prof. Gray and Sereno Watson; of 
Cambridge, Mass., Dr. Vasey, of Washington, and others assisted 
in the naming of some of the more difficult species.

at Washington, D. C., may be found an article, by Lester F.
