Common on low open ground near the coast of middle Cali- 

 fornia. Also on the Atlantic coast of North America and in 

 Mexico and South America. 



2. G. palustre Nutt, Trans. Am. Philos. Soc. ser. 2, vii. 403 

 (1841). LOWLAND CUDWEED. 



Plant .5 to 1.5 or 2 dm. high: stems commonly several and 

 erect or ascending from an annual root : herbage loosely floccose 

 with long wool, sometimes partially deciduous : leaves nearly all 

 spatulate, or a few about the inflorescence oblong or lanceolate, 



1 to 3 cm. long : heads in small dense clusters at the ends of the 

 branches : involucre barely 4 mm. high ; its bracts linear, brown- 

 ish or greenish at base, the pearly-white obtuse tips' sometimes 

 denticulate : achenes either smooth or scabrous. 



Occasional in moist places, especially on margins of ponds or 

 slow-flowing streams, from near the coast to 2500 m. alt. in the 

 mountains ; San Diego Co. to Washington and Wyoming. 



3. G. bicolor Bioletti, Eryth. i. 16 (1893). 



Stout, 6 to 9 dm. high, from a perennial root : stems branching 

 and .lignescent below, terminating above in a compact cyme or 

 branching to form a more or less open panicle, the branches of 

 which are terminated by close cymes: herbage glandular, whi- 

 tened by a very thick dense tomentum, which is deciduous only 

 from the upper surface of the leaves : leaves oblong, or linear, or 

 the upper lanceolate, closely sessile by a broad auriculate base, 



2 to 5 or 8 cm. long, .5 to 1 (or the lower even 1.5) cm. wide, the 

 margins commonly undulate and revolute: involucre carnpanu- 

 late, 6 mm. high and broad ; its bracts white, becoming sordid, at 

 least the inner often with a greenish tinge ; the outer ones ovate 

 and obtuse, the inner varying to narrowly oblong and acute. 



In the foothills and along the coast, from Lower California 

 to the Kaweah River and Monterey Co. ; common on low chap- 

 arral-covered hills of the Upper Sonoran Zone in the southern 

 part of its range. I have examined the following specimens, 

 many of which were distributed as other species, some even as 

 Anaphalis margaritacea: San Diego, Mar. 25, 1891, G. W. Dunn 

 (Univ. Calif, no. 31964) ; Botanic Garden, Berkeley, Sept., 1892, 

 Greene (Univ. Calif, no. 31962) ; 22 vicinity of San Diego, Wright. 



22 The first two specimens cited are presumably the ones from which the 

 original description was drawn.
