R. alismellus (Gray) Greene, PI. Fran. 297. 1891. This 

 also, if our plants are rightly referred, is subalpine or nearly so 

 with us. The originals from "Lake Tenayo and on Mt. Dana, 

 Sierra Nevada, to the height of 12,000 feet" (Gray, Proc. Am. 

 Acad. 7: 327. 1867), had subovate or oblong leaves an inch 

 long, on usually slender petioles. Our specimens, collected on 

 Slide Mountain, a massive granite peak elevation 10000 feet, 

 and just south of Mt. Rose, have leaves with lanceolate acute 

 blades about three inches long, and rather broad petioles two 

 inches long. The flowers are over an inch in diameter, bright 

 glossy yellow. I have seen similar plants at an elevation of 

 over 8000 feet, growing below snow banks in Placer county, Cal- 

 ifornia, near Summit station. 



On the Ruby mountains in Elko county, eastern Nevada, I 

 collected a Ranunculus which is probably referable to R. Esch- 

 scholtzii Schlecht. Ranunc. 2: 16. 1820, the type of which was 

 collected by Chamisso "in insulis Unalaschka et St. Georgii." 

 It was found at the head of a canyon, on the South Fork of the 

 Humboldt river, above Lee post office, at an elevation of 9900 

 feet, growing in wet places along streamlets where snow had 

 recently melted. The plants have the roundish 3-5-parted or 

 deeply cleft leaves of this species, with purplish glabrous sepals. 

 On the Clover mountains, as the northern part of the Ruby 

 mountains is called, was collected a very similar plant, growing 

 on wet slopes below snow banks, the elevation 9150 feet. It 

 differs in having a more conspicuous ciliate and scarious stipu- 

 lar dilation of the leaf, and the calyx is hirsute. Except for the 

 size of the flowers, which considerably exceed the calyx, it agrees 

 fairly well with the description of R. ocreatus Greene, Pittonia 

 4: 15. 1899, the type of which was collected on Mt. Hesperus, 

 Colorado. 



Ranunculus alpeopkilus A. Nelson, Bull. Torr. Club *><>: 

 350. 1899. Specimens collected above Lee post office in the 

 Ruby mountains, elevation 9900 feet, were found sparingly in 

 moist places where snow had recently melted. This agrees very 

 well with Professor Nelson's no. 7880, collected at Telephone 

 Mines, Albany county, Wyoming, except that it is taller and
