as opposed to larger size and light margined bracts in lanulosa^ 

 I can not separate it. 



Passing along the saddle, the ascent of the high point on 

 the north side was undertaken. On the way clumps of Senecio 

 cymbalarioides with golden masses of flowers were found about 

 rocks, and near by a handsome pale yellow flowered plant that 

 has undergone many vicissitudes at the hands of botanists. I 

 now intend to claim for it the rank of a genus, as Nuttall pur- 

 posed to do many years ago. It is no more at home in either 

 Linanthus or Leptodactylon, where it has recently been placed, 

 than it is in Gilia.

Since Gray described this in the place cited above, as well 

 as in the Synoptical Flora under the section Siphonella, it is 

 not necessary to repeat the description here. My impression of 

 the plant is that it blooms in the day time, while all the species 

 of Leptodactylon are nocturnal, opening early in the evening 

 and closing the next morning. Their flowers also have a pleated 

 appearance when closed, which is apparently not the case with 

 those of Siphonella. 



In damp soil about rocks at 10300 feet were Drymocallis 

 gracilis. Arnica mollis, and Epilobium obcordatum. The latter 

 is another of the species common also to the Sierra Nevada, but 

 is found as far east as the Rocky mountains. 



At 10850 feet, the highest point reached, Pellaea Breweri 

 was found growing in crevices of the rocks. It is common in 

 the Sierra Nevada, where it was first discovered. 



Coming down from the high point, a beautiful Erigeron 

 was found at 10200 in a moist meadow on the north side of the
