spreadinor branches, would associate it with the audrosaemifol- 

 ium group. It is probably nearest related to the glabrous A. 

 oliganthum Greene, of western Nevada, which has synonyms in 

 A. vianim Heller, Muhlenbercria 2: 110. 1906, and A. bicolor 

 McGregor, Hull. Torr. Club \M\ 261. 1910, the latter from the 

 type region of A. oliganthum. 



Just below the Apocynum station, in low ground near the 

 stream, in an aspen grove, Calochortiis nitidiis was plentiful. 

 This is one of our handsomest species, the perianth segments 

 white with a purple spot at the middle. They stand well apart 

 from each other, and are peculiar in being verv persistent. 

 This species is not recorded by Watson. 



For the greater part of the way the trail led along the 

 stream, crossing and recrossing it, winding through aspen thick- 

 ets and other undergrowth, much of it enlivened by clumps of 

 brilliantly colored flowers. 



At 8700 feet a halt in a meadow on the banks of the ice 

 cold stream, yielded the type of Carex fissuricola Mackenzie, 

 while near at hand were Allium validiim, Bistorta linearifolia 

 and Paniassia i?itermedia^ all originally collected in this range. 

 The latter is the Pariiassia fimbriata of Wat.son. 



At 9300 feet before climbing up a cross ridge, or rather a 

 bench which stretches acro.ss the canyon, and through which the 

 stream cuts at one side, an open place covered with coarse gran- 

 ite sand >ielded Spraguea nuda and Polygonum Austinae? the 

 former at least far removed from its hitherto known range in 

 the Sierra Nevada. 



Between 9550 and 9600 feet are found three small lakes, 

 and about them a rich profu.sion of plants. Several of the most 

 interesting are Sileue acaulis, carpeting dripping rocks, and 

 with it the diminutive Salix saximontana ; Pneumonanthe caly- 

 cosa on the raised wet borders of the lakes, in company with 

 Micranthes arguta and Callha rotuudifolia. Here the latter was 

 in fruit, while only a hundred feet higher in the open meadow 

 along the stream were numerous plants with newly opened flow- 

 ers.
