CATALOGUE OF SPECIES. 85 



Dalea johnsoni Wats. Bot. King Surv. 64 (1871). Type locality, "near St. 

 George on the Virgin River, Utah." 



Specimens were collected by Dr. Merriam and Mr. Bailey at St. George, Utah 

 (No. 1953). The species ,.,is a very restricted range, having been found, so far as 

 known, only in Washington County, Utah, and in the wash of the Diamond River, 

 northwestern Arizona, near its junction with the Grand Canon of the Colorado 

 (Lemmon, 1881). Dr. Merriam found a Dalea, which he supposes to bo of this 

 species, on the eastern slope of the Beaverdam Mountains. 



Dalea mollis Benth. PI. Hartw. 306 (1848). Type locality, ''in vicinibns Mon- 

 terey." 



This plant has not been rediscovered at Monterey, and as it is a species character- 

 istic of the lower Great Basin region, the locality given by Bentham is probably, as 

 suggested by Dr. Watson in the Botany of California, erroneous. 



Specimens were first observed at Bennett Wells in Death Valley, and afterward at 

 other points as follows: in a canon of the Funeral Mountains, opposite Bennett 

 Wells; in Furnace Creek Canon; at Kcsting Springs; between Ash Meadows and 

 Pahrnmp; in the Vegas Wash (No. 1891); on the mesa between Bennett Wells and 

 Johnson Canon (No. 474) ; in Panamint Valley near the mouth of Hall Canon, and in 

 Surprise Canon. 



This is one of the characteristic plants of the Lower Sonoran. Its favorite habitat 

 is hot gravel-beds such as occur in the bottoms of canons and on the slopes between 

 mountains and valley-bottoms. 



Dalea polyadenia Torr. in Wats. Bot. King Surv. 64 (1871). Type locality, 

 "border of Truckee DeBcrt, Nevada." 



Dr. Watson has described l from "Owen's Valley 7 ' a variety, snbnuda, of this species. 

 Our plant from its locality might be expected to belong to this variety, but it ap- 

 pears to differ in no essential detail from the type form. 



A leafless Dalea, which I take to be of this species, was seen in January in Para- 

 dise Valley, and a few plants occurred on the south slope of Browns Peak (No. 172), 

 but the species was not met with again until we reached Owens Valley. It occurred 

 there between Keeler and Lone Bine (No. 950), between Keeler and Darwin, and be- 

 tween Lone Pine and Olancha, growing in arid gravelly or sandy soil. Dr. Merriam 

 found it also in Leach Point Valley and Deep Spring Valley, California; in Fish 

 Lake Valley, Grapevine Canon, Sarcohatus Flat, Oasis Valley, and Pahranagat Valley, 

 Nevada; and at the great bend of the Colorado River. 



Robinia ueomexicana (iray, PI. Thurb. 314 (1854). Type locality, "Dry hills on 

 the Mimures, New Mexico."' 



Reported by Dr. Merriam from the Santa Clara Valley and the eastern slope of the 

 Beaverdam Mountains, Utah. 



Astragalus amphioxys ' Gray, Proc. Amer. Acad. xiii. 3G6 (1878). Type locality, 

 " Southern Utah and New Mexico and Northern Arizona." 

 In the Panamint Mountains (Nos. 49(5, 543). 



Astragalus atratus Wats. Bot. King Surv. 09 (1871). Type locality, "on the 

 Pah-Ute, Havallah, and Toyabe ranges, Nevada; 6-7,000 feet altitude." 



On the Darwin Mesa (No. 792), and near Mineral King in the Sierra Nevada (No. 1561). 



Astragalus beckwithii Torr. & Gr. Pac. R. Rep. ii. pt. ii. 12) (1855). Type 

 locality, "on the Cedar Mountains, west of Lone Rock, and south of Great Salt 

 Lake," Utah. 



Telescope Peak (No. 2022). 



L Bot. Cal. ii. 441 (1880). 



1 The species of Astragalus were determined by Mr. E. P. Sheldon.
