extremely viscid : cauline leaves thin, acerose-pinuatifid; the 

 the floral ones, broadly ovate, not much cleft, hardly spin- 

 escent; tube of corolla, very slender and not exceeding the 

 calyx-lobes, the limb broad : stamens exserted and strongly 

 declined; seeds small, 4-5 in each cell. 



Hills west of Calistoga, Napa County, collected by the 

 writer in June, 1881, and again in August, 1883. 



Intermediate between G. jilicaidis and G. viseidula, the 

 species, is, nevertheless, an uncommonly well marked one> 

 being much more viscid than either of its near relatives, 

 having a shorter tube and broader limb to its corolla, and 

 23roducing from four to five or more seeds in each cell, 

 whereas neither of the others aboved named has more than 

 two, usually only one. Its stamens are as strongly declined as 

 in any Polemonium, in which respect it is a most peculiar 

 member of the Navarretia section of the genus. 



Eriogonum arborescens. 



Shrubby and stout, several feet high, with a stem 3 — 4 



inches thick; leaves crowded at the ends of the numerous 

 branchlets, coriaceous, linear-oblong, an inch or more long, 

 strongly revolute, white tomentose beneath, glabrate above : 

 peduncles stout and rigid, naked, six inches long, bearing 

 an ample compound cyme: flowers small, rose-colored, the 

 lower outside portion densely white-villous. 



Probably the largest species of the genus; very strongly 

 marked, but little known. The specimens were brought 

 from Santa Cruz Island by Messrs. Kellogg and Harford in 

 1874. 



Spargaimim Californicum. 



Erect, rather slender, 3 — 9 feet high, with branching in- 

 florescence; leaves flat and thin; heads 4 — 10: fruit sessile, 

 wedge-shaped, many angled, 3 — 4 lines long, with a broad, 

 nearly hemispherical summit, tipped with the short style. 



First observed by Dr. C. C. Parry and the writer, in 

 June, 1881, in a swampy place in the western portion of the 

 village of Calistoga; occurring also in the tules near Sacra-
