PREFACE. 



In the summer of 1899 Mr. Pierson Durbrow, Mr. S. L. Berry 

 and Mr. Benjamin Brooks planned a trip of two weeks to the 

 south fork of Kings River. Knowing my great desire to explore 

 this region, chiefly for the sake of its flora, they kindly invited 

 me to be one of the party. We were twelve days (July 2-14) in 

 the region, and traveled on foot from Millwood to the headwaters 

 of Bubbs Creek, ascending both branches, the one leading to East 

 Lake and Harrisons Pass, the other to Bullfrog Lake and Kear- 

 sarge Pass. We ascended what is known as Mt. Stanford, but no 

 other peak as the time was too limited. 



We had only two animals to carry our baggage, and, since pro- 

 visions and bedding were necessary, my botanical outfit had to be 

 very limited and 1 was not able to collect as much as I would 

 have liked. Then, too, the time was so short, so that while I 

 tried to collect specimens of all the different kinds of plants that 

 grew along the trails, none were collected in abundance ; possibly 

 some of the commoner species were neglected, and probably some 

 of the rarest overlooked. 



This collection has, however, been supplemented by two collec- 

 tions made by myself around Millwood in previous years, and by 

 one made by Mr. T. S. Brandegee in the same region some time 

 ago. All the plants from General Grant Park were collected by 

 Mr. Brandegee. There are also a few, and some of the most in- 

 teresting, which were collected by Miss Catherine E. Wilson and 

 others of a party that visited the Bubbs Creek region in 1897. 



This is the first attempt to make a Flora of the Southern Sierra 

 Nevada, and it is necessarily incomplete; but this will perhaps be 

 an incentive to more thorough work, and it is hoped that the 

 members of the Sierra Club will be able to increase the number 

 of species considerably during the coming trip. 



Accuracy, simplicity, completeness and brevity have been the 

 constant thought in aiming to compile a Flora that would suit
