U8ually pubescent leaves, larger iVuit, and dillereiit inflorescence. 

 S.vermkalatm usually grows, in Nevada, 1.2 to 1.8 ni. high, with 

 branches less intricate and often not spine-tii)ped, and leaves 

 when well developed 12 to 20 or even 30 mm. long and almost 

 invarialdy glabrous. Its fertile flowers are descril)ed ]jy Ben- 

 tham and Hooker* as axillary and solitary, but the axis on which 

 they are l)orne is really continued into a rudimentary male spike- 

 let similar t(j that of S. IxvUeyi, l)ut each floral axis, instead of 

 bearing 1 or 2 female flowers as in that species, conmionly has 

 from 4 to 8. In S. vermiculatus the body of the fruit is 4 to 5 

 nun. long, 2.5 to 3.5 mm. broad, and the wing 7 to 13 mm. l)y 5 

 to 8 mm. in diameter. 



Type specimen in the United States National Herbarium, No. 

 1994, Death Valley Expedition; collected June 2, 1891, in a 

 valley near Thorpe's quartz-mill, Nye County, Nevada, by Ver- 

 non Bailey. 



The plant was first seen by Mr. Bailey at Cloverdale, Esme- 

 ralda County, Nevada, in 1890, and recognized by him as differ- 

 ent from S. vermiculatus. In comi)any with Dr. Merriam he 

 afterward found it in a valley in Nye County, Nevada, southeast 

 l)y east from Gold Mountain, near Thor})e's quartz-mill, and 

 later in Fish Lake Valle}' westward from tlie other localities, on 

 the California state line. There is in the National Herl)arium a 

 specimen of the same plant collected l)y J. G. Lemmon in 1875, 

 probably in western Nevada. The species is therefore confined, 

 so far as known, to the counties of Esmeralda and Nye, in Ne- 

 vada, and Mono and Inyo, in California. I take pleasure in as- 

 sociating Mr. Bailey's name with this shrub, both as a mark of 

 his earnest and invaluable lal)ors in the field of natural history 

 and as a reminder of a warm friendshi]) established among the 

 vicissitudes of a desert exploration. 



Saxifraga integrifolia sierrae var. iiov. 



Blades of larger leaves 8 to 12 cnj. long, oblong-lanceolate to 

 elliptical-]an('eolate, acute, conspicuously serrate-denticulate, 

 from glabrous to s[)aringly clammy-hairy above and l)eneat]i, 

 tliinner and more distinctly veined than in the type ; petiole and 

 margin of the leaf toward the base ciliate with clammy hairs ; 

 otherwise as the type form. ^
