120 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Coleosanthus linifolius (Eaton) Bot. King Snrv. 137 (1871), under Briokellia; 

 Kuntze, Rov. Gen. PI. i. 328 (1801). Typo locality, "sandy bottoms of American 

 Fork, Jordan Valley, Utah." 



Between Darwin and Keeler (No. 913). 



Coleosanthus longifolius (Wats.) Amor. Nat. viii. 301 (1873), under Briokellia; 

 Kuntze, Rev. Gen. PI. i. 328 (1891). Type localities, "Southern Nevada" and 

 "Northern Arizona." 



This shrub was soeu in Surprise and Willow Creek eaftona, Pauamint Mountains; 

 in a canon on the west slope of the Inyo Range, near Swansea ; and near the mouth 

 of Cottonwood Creek, on the west shore of Owens Lake. It grew along the beds 

 of streams, usually those that do not dry up in the summer, and it scarcely ever ex- 

 ceeded the limits of the Lower Sonoran zone. At Brewery Spring, in Surprise Canon, 

 the plants commonly reach a height of 2 meters, and one of them measured 2.9 meters. 



Bsbbia juncea aspera Greene, Bull. Cal. Acad. i. 180 (1885). Type locality not 

 mentioned, but geographic range given as "southern borders of California and 

 adjacent Arizona." 



The typo specimens of this species were collected at the Bay of Magdalcna, Lower 

 California, and were referred to the genus Carphephorus. 1 That form has been col- 

 lected since in several parts of Lower California and the adjacent lands. The 

 variety aspera, which alone is known to occur in the United States, has smaller, nar- 

 rower heads than the typo, while the involucral bracts are all lanceolate and 

 acute. In the type form the bracts, except the scarlet inner ones, are from ovate to 

 oblong-ovate, and broadly rounded or very abruptly acute at the apex. The varietal 

 name aspera is unfortunate, as the stems are usually quite glabrous and only occa- 

 sionally short-hispid. 



The plant grew in Furnace Creek Cafion (No. 238); in the Funeral Mountains, 

 near Saratoga Springs and west of Amargosa ; in Resting Springs Valley and 

 Resting Springs Mountains ; between Vegas Ranch and Corn Creek, in Vegas Valley, 

 Nevada; and in Johnson and Willow Creek canons, Panamint Mountains. It is a 

 characteristic though scarcely abundant species of the Lower Sonoran zone. 



Gutierrezia microcephala (DC.) Prodr. v. 313 (1836), under Brachjria; Gray, 

 PI. Fendl. 74 (1810). Type locality, "in Mexico prope locum dictum Sallito." 



Specimens were collected only near Lone Willow Spring (No. 178) and in Pahrump 

 Valley (No. 201), but the plant occurred at other points. 



Amphiaciiyris fremontii Gray, Bost. Journ. Nat. Hist. v. 108 (1815), under 

 Amphipappus; Gray, Proc. Amer. Acad. viii. 633 (1873). Type locality, "along the 

 Mohave River." 



This species was first distinguished from the other desert shrubbery February 2, 

 1891, in the Funeral Mountains, a few miles north of Saratoga Springs (No. 260). 

 From that time it was seen frequently : in Resting Springs Valley and the mountains 

 east of it; on the mesa east of Winters's ranch, Pahrump Valley, Nevada; at Bunker- 

 ville, Nevada (No. 1934); in the Funeral Mountains, west of Amargosa; on the 

 rocks about Devil Hole, Ash Meadows; in Johnson Canon, Panamint Mountains, 

 and the wasli leading from it ; and in Surprise Canon, in the same range. The shrub 

 is one of frequent occurrence in the desert, yet it never forms a conspicuous part of 

 the vegetation. It is a well-defined Lower Sonoran species, and extends from the 

 upper limit of Larrea down to an altitude of about 2,500 feet. The favorite habitat 

 of the shrub is on rocky mountain slopes, but it often occurs in gravelly washes, and 

 sometimes on an open mesa. 



Heterotheca grandiflora Nutt. Trans. Amer. Phil. Soc. now ser. vii. 315 (1811). 

 Type locality, "on rocks near the sea, round St. Barbara, Upper California." 

 Near San Bernardino (No. 22). 



'Beuth. Bot. Sulph. 21 (1814).
