the northeast side, were visited, and, although the entire region . 

 is considered in the chapters devoted to plant distribution, it is 

 to be noted that only those species of plants found in or above 

 the Yellow Pine belt are included in the list which closes this 

 report. 



Of the visits made to the mountain the first on which any 

 extensive botanical collecting was done was in 1896, when about 

 six weeks during the months of August and September were 

 spent in botanizing principally over the south side, but a trip 

 was also made through some of the higher valleys of the east 

 side to the main peak. During this season the writer was accom- 

 panied by Mr. A. R. Morrison, who rendered valuable assistance 

 in the collection and preparation of specimens. The next year 

 four excursions were made to the mountain, beginning with 

 May 1 and extending to the last of July. The first of these was 

 to Fuller's mill, which has an altitude of 5800 feet, and as snow 

 was then lying on the ground the advisability of confining our 

 early collecting to the lower altitudes became apparent; but in 

 July two visits were made to the region around the highest peaks 

 and collections made. In 1898 a few days in the latter part of 

 June and the first of July were spent l)otanizing along the south 

 side and as far up as Strawberry Valley, and on this trip Toro 

 and Santa Rosa Mountains, the southeastern continuation of 

 San Jacinto, were visited for the second time. Practically the 

 same ground was covered in 1899, but this time during the latter 

 part of May. 



From May 15 to June 1, 1901, a collecting trip in company 

 with Professor W. L. Je])son was made to Strawberry Valley, 

 Palm Canon, Santa Rosa Mountain, and other localities to the 

 south. The author of this paper then decided to make as thor- 

 ough an ex])loration of the Flora of San Jacinto Mountain as 

 time would permit. A camp was therefore established in Straw- 

 berry Valley, and between June 19 and August 7 all parts of the 

 mountain above the chaparral belt were again gone over, collec- 

 tions of the flowering plants made, and notes on distribution 

 and abundance taken. The results of this survey are given in 

 the following pages.
