130 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Xanthium strumarium L. Sp. PL ii. 987 (1753). Type locality, "in Europa, 

 Canada, Virginia, Jamaica, Zcylona, Japonia." 



Tliis weed, the cocklebur, was recorded in the desert only at Resting Springs, and 

 at Mountain Springs, Charleston Mountains. In the Tulare Plains it occurred fre- 

 quently on irrigated ground. 



Gymnolomia multiflora (Nutt.) PL Gamb. 171 (1848), under Heliomeris; 

 Rothr. Bot. Wheeler Surv. 160 (1876). Type locality, "mountains of Upper Cali- 

 fornia." 



Mill Creek Canon, Panamint Mountains (No. 806). These specimens are perennial, 

 and have their leaves opposite throughout. 



Rudbeckia californica Gray, Proc. Amer. Acad. vii. 357 (1868). Type locality, 

 "Mariposa Big-tree Grove/' California. 

 At Soda Springs on Kern River (No. 1591). 



Balsamorhiza deltoidea Nutt. Trans. Amer. Phil. Soc. new ser. vii. 351 (1841). 

 Type locality, "near the outlet of the Wahlamet," Oregon. 



The Californian plant commonly referred to this species differs from true B. del - 

 toidea of Oregon and Washington in its scabrous leaves aud hirsuto-ciliate, smooth 

 or slightly pubescent involueral' bracts, contrasting with the sparingly soft-pubes- 

 cent leaves and woolly involueral bracts of that plant. It has been described ' under 

 the name B. glabrescens from specimens collected in "Bear Valley montium Sacra- 

 mento." It will undoubtedly be found necessary to separate the southern form 

 either as a variety or a species. 



The plant was found only on the divide between Havilah and Kernville (No. 

 1067), and on the divide between Havilah and Walker Basin. 



Balsamorhiza hirsuta Nutt. Trans. Amer. Phil. Soc. new ser. vii. 349 (1841). 

 Type locality, "dry plains east of Walla- Walla, near the Blue Mountains, and in the 

 Grand Rondo prairie." 



About 30 kilometers east of Panaca, Nevada (No. 1977). Our plant is the same as 

 No. 596 of the King Survey, which Professor Eaton and Dr. Gray have referred to this 

 species of Nuttall. I have not been able to examine the type specimen. 



Balsamorhiza invenusta (Greene) Pittonia, i. 284(1889), under Helianthus. Type 

 locality, "mountains of Kern County, California." 



This plant, although heretofore referred to Helianthus, cannot reasonably be placed 

 there, for the linear, quadrangular, slightly compressed achenia are entirely devoid 

 of pappus. Our plant is 55 cm. high, loafy to the top, with alternate or opposite, 

 ovate-lanceolate, acute, scabrous, petiolate, entire leaves 8 to 15 cm. long, the base 

 cordate or tapering. The involueral bracts are herbaceous, narrowly oblong, acute, 

 and scabrous-hispid. In its leafy stems it resembles Balsamorhiza iolavdcri, but it 

 differs from that species in haying no ray-flowers. 



The plant has been collected only in the southern Sierra Nevada, the original speci- 

 mens by Edward Palmer "at a height of 6,000 or 7,000 feet, upon the Green Horn 

 Mountains, 10 or 12 miles west of Kernville, Kern County, Cal.;" 2 the present speci- 

 men (No. 1373) in dry soil in grooves of Pinm jeffreyi, on the slopes of Big Tree Canon, 

 between Three Rivers and Mineral King, Tulare County, California. 



Viguiera reticulata Wats. Amer. Nat. vii. 301 (1873). Type locality, "Telescope 

 Mountain, southeastern California," not from Nevada, as stated by Gray. 3 



Some incomplete specimens of this plant bearing the date 1872 were collected 

 on the Wheeler Expedition in the vicinity of Telescope Peak ; but no other specimens 

 have since been found. Our own specimens were collected in midwinter, in a warm 

 situation, and bore empty fruiting involucres, uew leaves, aud a few flowering heads.
