CATALOGUE OF PLANTS. 



By Piior. Thomas C. Porter. 



All the plants comprised in this catalogue were collected during the 

 expedition of Dr. F. V. Hayden to the head-waters of the Yellowstone 

 Biver in the summer of 1871, with the exceiJtion of a small number 

 gathered by Dr. George Smith, in the month of August, on Gray's Peak 

 and near Georgetown, Colorado Territory. 



Prof. G. IST. Allen acted as botanist, and Eobert Adams, jr., as assist- 

 ant, as far as Fort Ellis. After that time Mr. Adams took charge of the 

 collections until his departure, about September 1. 



Thanks are due to Doctors Torrey and Gray for valuable aid in diffi- 

 cult cases, and to Messrs. Engelmann, Olney, Thurber, Lesquereux, and 

 Tuckerman for the determination of species in those orders to which 

 they have devoted special attention.
