124 BOTANY OF THE DEATH VALLEY EXPEDITION. 



identical with that found in the Rocky and Cascade mountains, as well as those of 

 northern Utah. It has not been reported before from the Sierra Nevada, yet it seems 

 to differ from the smaller form only in its size. 



Solidago occidentalis (Nutt.) Trans. Amor. Phil. Soc. new eer. vii. 326 (18-11), 

 under Euthamia; Torr. & Gr. Fl. ii. 22G (1842). Type locality, " banks of the Ore- 

 gon and Wahlamet, and Lewis River, in the Rocky Mountains." 



North Fork of Kern River (No. 1735). 



Solidago spectabilis (Eaton) Bot. King Surv. 154 (1871), as G. gmradotiis spec- 

 tabilis; Gray, Proo. Amer. Acad. xvii. 193 (1882). Type locality, "stream banks, 

 mountains of western Nevada to the East Humboldt Mountains; 5,500 to 7,000 feet 

 elevation." 



In these specimens the involucral bracts are acuminate instead of obtuse, as in 

 the type specimens, but in this respect they are identical with some of the Wheeler 

 Survey plants, originally named S. guiradonis, but subsequently referred by Gray 

 to S. spectahilia. The plant occurred in Furnace Creek Canon, Funeral Mountains 

 (No. 212) ; in Resting Springs Valley (No. 286) ; at Ash Meadows; at Mountain Springs, 

 Charleston Mountains; at several springs in Vegas Valley ; and in Johnson. Sur- 

 prise, and Hall canons, Panamiut Mountains. It always grew in soil moistened with 

 scarcely alkaline water, and usually within the limits of the Lower Sonoran zone. 



Lessingia lemmoni Gray, Proc. Amer. Acad. xxi. 412 (1886). Type locality, 

 "at Ash Fork, in northern part of Arizona." 



This species differs very little in outward appearance from L. glandulifera, while 

 both of them are clearly distinct from L. germanorum, L. lemmoni is almost con- 

 stantly green throughout, while L. glandulifera usually has purple branches and often 

 purple involucral bracts ; but the crucial distinction lies in the slender-subulate style- 

 tips of L. lemmoni and the obovate or ovate, penicillate style-tips of L. glandulifera. 

 An examination of several specimens (Lemmon, 1884, "near Mohave;" Pringle, 1882, 

 "Mojave Desert;" Palmer, 1870, No. 201), besides a duplicate of the type specimen 

 and our own plant, show that subulate style-tips are constant in all those from the 

 Mohave Desert region and eastward, while all plants from intramontane California 

 have tho blunt style-tips of L, glandulifera. Although the two plants are not widely 

 different, the distinction appears constant. 



Our specimens were collected at the eastern base of the Coso Mountains (No. 906). 



Lessingia leptoclada microcephala Gray, Proc. Amer. Acad. vii. 351 (1808). 

 Type locality, "on Bear Mountain." 



In the valley of the Kaweah River (No. 1324). In these specimens the bristles of 

 the pappus are conjoined at the base into about five phalanges, upon which charac- 

 ter mainly, with the smaller size and fewer-flowered anthodia, this plant has been 

 separated l as a species. But the same character of tho pappus appears in large forms 

 with 15-flowered heads, and, so far as herbarium specimens show, is not constant. 



Lessingia tennis (Gray) Bot. Cal. i. 307 (1876), as L. ramulosa tenuis. Typo 

 locality, 2 "Peru Creek [Ventura County, California], at 5,100 feet." 



At tho western base of Frazier Mountain (No. 1199). Full-grown anthodium 6 to 

 7 mm. high, broadly turbinate; corolla 5 mm. long, the limb regular and purple; 

 stylo tips truncate-penicillate, with a small subulate appendage among the hairs; 

 pappus composed of about twenty equidistant bristles, or of fewer bristles arranged 

 in five groups, those of each group often reduced to a single one. This plant ap- 

 pears quite distinct from L. ramulosa, the anthodia of that species when fully devel- 

 oped being 9 to 10 mm. long, oblong-turbinatc, and the corolla 7 to 8 mm. long. 



Townsendia scapigera Eaton, Bot. King Surv. 145 (1871). Typo locality "dry 

 rocky ridges in the Trinity and Pah-Ute Mountains, Nevada; 5-6, 000 feet elevation." 

 In the Inyo Mountains (No. 1781).
