364 PHANEROGAMOUS PLANTS. 



without the rose-tint. — Apparently a pretty well-marked species, with 

 smaller heads than those of G. Calif or nicum, panicled on numerous 

 slender branches, the scales of the somewhat turbinate involucre 

 yellowish-white or sordid, sometimes tinged with rose-color, not sil- 

 very-white, narrower, and mostly somewhat pointed. Herbage glan- 

 dular and odorous. — Whether Q. Californicum is specifically distinct 

 from 0. decurrens is still uncertain, but we have the latter from Fraser 

 River, Northwest America, collected by Mr. Wallace. 



2. Gnaphalium Sprengelii, Hook. & Am. 



Hab. Bay of San Francisco, California. — A great part of the spe- 

 cimens which we have from time to time referred to this species per- 

 haps belong to the following ; but this can hardly be the case with the 

 present specimens, which resemble those of Hartweg's No. 1811, except 

 that the involucre is whiter. 



3. Gnaphalium luteo-album, Linn. 



Hab. Gray's Harbor, Puget Sound, and in California, common. — 

 To this belongs the greater part of what has been called Q. Spreyigelii, 

 Still the American plants do not well accord with the European 

 Q. luteo-allum. 



4. Gnaphalium palustre, Nutt. 



Hab. Interior of Washington Territory and Oregon, and, in Cali- 

 fornia, on the Sacramento, &c. 



5. Gnaphalium (Gamoch^eta) purpureum, Linn. 



Hab. San Francisco, California. — This species (for which the Lin- 

 naaan name claims to be retained), as Dr. Hooker (Fl. Antarc. 2, p. 

 309) and Weddell (Chloris Andina, 1, p. 229) agree, embraces all the 

 American species of the group, which Weddell has on plausible grounds 

 raised to the rank of a genus. Nuttall's Q. ustulatum must be one of 

 the many forms of the species.
