104 BOTANY OF THE DEATH VALLEY EXPEDITION. 



CBnothera tystorta Nutt. in Ton. &, Gr. Fl. i. 508 (1840). Type locality, " St. 

 Diego, California." 

 Near San Bernardino (No. 31). 



CBnothera brevipes Gray, Pac. R. Pep. iv. 87 (1856). Type locality, "gravelly 

 hills on and near the Colorado," in Arizona or southern California, 



This species has, typically, villous pubescence and lyrate-pinnatified leaves. 

 Toward the base of the stems, however, there is always some puberulence, among 

 the long hairs on the lower part of the stem, and the villous pubescence is frequently 

 wanting. The lateral lobes of the leaves are frequently very few and sometimes 

 entirely wanting. These changes from simple to lyrately-pinnatifid leaves, and 

 from a densely villous to puberulent (or above glabrous) surface, together with a 

 variation in size from a very few to GO cm., give the species a wide range in general 

 appearance; but the bright yellow petals 1 to 2 cm. long distinguish it from (E. 

 scapoidea. 



It is a common plant of the desert and was recorded in the southern part of the 

 Funeral Mountains (No. 253); in Furnace Creek Canon (Nos. 359, 438); between 

 Bennett Wells and the month of Johnson Canon (No. 482); near Hot Springs Pana- 

 mint Valley (No. 606) ; near Keeler; and on the road from Keeler to Darwin. 



CBnothera caespitosa Nutt. Gen. i. 246 (1818). Types locality, "on denudated 

 and arid argillaceous hills on the banks of the Missouri, from White river to the 

 Mandans, and in all probability to the commencement of the [Rocky] mountains." 



In our plant the sepals and leaves are short-villous, the latter especially so on the 

 margins; and the valves of the capsule are but lightly 2-keeled. It was seen in 

 Johnson (Nos. 535, 2081), Willow Creek, and Mill Creek canons, Pauamint Mountains- 

 and between Keeler and Crystal Spring. 



CEnothera californica Wats. Proc. Amer. Acad. vfii. 582 (1873), as (E. albican Us 

 caU/ornioa; Wats. Pot. Cal. i. 223 (1876). Type locality. "California," 



The long hairs in No. 1012 are so very dense that the whole herbage appears white. 

 Specimens were collected near Lone Pine (Nos. 952, 1777), near Indian Weils (No! 

 1012), and in the western end of Antelope Valley. All these places, although in 

 the desert region, are near its margin. 



CEnothera cardiophylla Torr. Pac. R. Rep. v. 360 (1856). Type locality, "near 

 Fort Yuma." 



All these specimens are more scantily hairy than the type, and the hairs are in- 

 cliued to bo gland-tipped. The capsules are usually sessile. The species is com- 

 inonly considered an annual, but in these regions the plant has a suffrutescent base 

 living through at least one winter. It occurred in a canon of the Funeral Moun- 

 tains, opposite Bennett Wells (No. 208), and in Snrpriso Canon, Pauamint Moun- 

 tains (Nos. 024, 725). 



CEnothera contorta Lehm. in Hook. Fl. Bor. Amer. i. 214 (1834)— Don gl. MS. 

 Type locality, "sandy barren soil, on the interior banks of the Columbia River."" 



Near Crystal Spring, Coso Mountains (No. 938), and near Havilah (No. 10X2), in the 

 southern Sierra Nevada. The petals in some of these plants are 4 mm. long. The 

 name given above is an older one, as noted by Dr. Watson, 1 for (E. strigulow. As 

 they are considered synonymous by the same author, 2 the older name is here used. 



CBnothera contorta pubens (Wats.) Proc. Amer. Acad. viii. 594 (1873), as <E Htrigu- 

 losa pttbens. Type locality not given ; range, " from Washington Territory to south- 

 ern California, and through northern Nevada to the Wahsatch." 



Mill Creek Canon, Pauamint Mountains (No. 762).
