A handsome white flowered Poleinonium, referred doubt- 

 fully by Dr. Rydberg to P. Jlavuvi Greene, was found in granite 

 at 9200 feet. He remarks that the leaflets are broader and the 

 inflorescence more open than is usual in that species, and this 

 station is considerably outside of its known range, which is Ari- 

 zona and New Mexico. It is undoubtedly the P. foliosissimtnn 

 of Watson, but does not altogether agree with that or any other 

 species, so far as I have been able to study it. 



A descent to 8950 feet to a low place in search of water led 



to fine collecting ground. There was no surface water, but the 



ground was moist, and among the clumps oi Salix glaucops 



glabrescetis was a variety of plants, both annual and perennial. 



Here, still in the granite, were Delphinium diversifolium, the 



D. ciepaitperatum of Watson, a little Oreobroma, no doubt O. 



pygmaea, a small Polygonum referred to P. tinifoliiim^ a minute 



Mimulus, still undetermined, with small, pale purplish flowers, 



and near by an equally small as well as perplexing one with 



yellow flowers. The one is very glandular, the other nearly 



smooth. Carex /estiva, C. heteroneura and C. Hoodii were 



"growing in close proximity in the rich loose soil, while near by 



was Arabis philoiiipha, and a Mertensia referred to M. ciliata 



Dr. Rydberg. 



At 9750 feet, just above the granite, in places where the 

 melting snow banks in their downward movement had formed 

 patches of moist loose soil, the less sericeous and more slender 

 form of Acomastylis sericea was plentiful, and near at hand, 

 often sheltered by a large stone or rock, the reddish tufts of the 

 now familiar Oxyria digyna, found all over the country at alpine 

 heights. On the steep slope above, leading up to the crest, was 

 Festuca calligera, and on the crest itself, among rocks, Symphor- 

 icarpos vaccinoides, while close by were masses of an unknown 

 Pentstemon, the violet flowers large and showy. This ridge 

 yielded the following species not mentioned by Watson; 

 Festuca calligera Salix glaucops var. 



Carex heteroneura Phoenicaulis Menziesii 



Hoodii Mertensia ciliata
