86 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Astragalus calycosus Wats. But. King Snrv. 66 (1871) — Torr. MS. Type locality, 

 "West Humboldt, East Humboldt, and Clover Mountains, Nevada; 8,000 to 11,000 

 feet altitude." 



Inyo Mountains (No. 1780). The description and figure given by Dr. Watson fully 

 characterize the species. The " ail very-sericeous " pubescence is made up of pick- 

 shaped hairs. 



Astragalus casei Gray, Bot. Cal. i. 154 (1876). Type locality, "high plateau 

 near Pyramid Lake, N. W. Nevada." 



In the valley of Willow Creek, Panamint Mountains (Nos. 717, 783). This species 

 has not been reported before from California. 



Astragalus coccineus Brandegee, Zoe, ii. 72 (1801). Type localities "near the 

 summit of the Inyo Kange", and "at Lone Pine on the slopes of Mount Whitney". 



This is a plant described by Dr. Watson 1 in 1882 as A. grand iflorus, his specimens 

 coming from the northern slope of the San Bernardino Mountains, in the edge of the 

 Mohave Desert. An Astragalus grandifloms, however, was described by Pallas in 

 1800. Our specimens were collected in Johnson Canon, Panamint Mountains (No. 491), 

 the only point at which the species was observed. The flowers when fresh are of a 

 bright scarlet color, and are among the iirst to open, at this altitude, in the spring. 

 They form a most brilliant and beautiful feature of the flora. The same plant was 

 collected by Mr. C. R. Orcutt on the western borders of the Colorado Desert in April, 

 188!), and the name Astragalus purshii coccineus was given to it by Parry, without 

 description, in West. Amer. Sci. vii. 10 (1800). The localities here mentioned are all 

 that have been reported for this plant. It is (dearly a species characteristic of the 

 mountain slopes of ultramontane California, and appears to becoufined to the regions 

 of the Mohave ami Colorado deserts, in Inyo, San Bernardino, and San Diego counties. 



Astragalus eremicus Sheldon sp. nov. 



Annual, erect, 7.5 to 13 cm. high, loosely branching from the base ; stems pubescent 

 with white, appressed, at length spreading hairs; leaves 4 to 5 cm. long, petioles thick- 

 ish ; leaflets 7 to 11 , oblanceolate to obovate, retuse, silvery-silky with close, appressed 

 hairs ; stipules deltoid-acuminate, usually rcflexed ; peduncles shorter than the leaves ; 

 racemes capitate or subcapitate; flowers small, 6 to 7 mm. long; calyx campanulate 

 with short, acute teeth, whitened with long, appressed hairs; corolla ochroleucous, 

 petals tipped with purple; pod ovate, membranaceous, sessile in the calyx, nearly 

 glabrous or with minute, scattered pubescence, 1.2 to 2 cm. long, didymous, com- 

 pletely 2-celled, minutely mottled and minutely reticulated throughout. 



Type specimen in the United States National Herbarium, No. 888, Death Valley 

 Expedition; collected June 7, 1891, near Lone Pine, Inyo County, California, by 

 Frederick V. Coville. 



This plant is nearly related to Astragalus plaiytro pis Gray, and Astragalus coulteri 

 Benth. The appressed pubescence and peculiar pod are characteristic. 



Astragalus inyoensis Sheldon sp. nov. 



Perennial; stem erect, glabrous or sparingly hirsute, with short, appressed hairs, 

 30 to 60 cm. high, loosely blanching; leaves 2 to 5 cm. long, mostly attached at right 

 angles to the stem ; leaflets 16 to 20, oval or obovate, obtuse or retuse, 4 to 6 mm. long, 

 petiolulate, smooth above, but minutely canosceut with short, appressed hairs be- 

 neath; stipules triangular, acute, rcflexed; peduncles elongate , 5 to 10 cm. long, 

 minutely appressed-hairy; racemes capitate at first, at length open; flower 6 to 10 

 mm. long; calyx obliquely attached to the pedicel, tube campanulate, teeth acute; 

 corolla purple; pod one-celled, membranaceous, inflated, oblong-ovate, finely reticu- 

 lated, short-atipitate, purplish-mottled, and sparingly pubescent, at least when 

 young.
