72 BOTANY OF THE DEATH VALLEY EXPEDITION. 



This species occurred in the clefts of naked rocks, on steep slopes, and in cafions, 

 near the upper spring at Loue Willow Spring (No. 162) ; near Mesquite Spring, in 

 the Funeral Mountains (No. 329) ; in Surprise Canon and Willow Creek Canon (No. 

 830), Panamint Mountains; and at Crystal Spring, Coso Mountains (No. 916). 



Lceflingia squarrosa Nutt. in Torr. & Gr. Fl. i. 174 (1838). Type locality, "sandy 

 plains, St. Diego, California." 

 Walker Basin (No. 1091). 



PORTULACACE.5I. 



Oreobroma nevadensis (Gray) Proc. Amer. Acad. viii. 623 (1873), under Calan- 

 drinia; Howell, Erythea, i. 33 (1893). Type localities, " Bubal pine region of Wah- 

 satch and East Humboldt Mountains [Nevada]," and ''Sierra Nevada, California, 

 at Summit and Cisco." 



Near Mineral King, Sierra Nevada (No. 1518). 



Oreobroma pygmaea (Gray) Amer. Journ. Sci. ser. 2. xxxiii. 407 (1862), under 

 Talinum; Howell, Erythea, i. 33 (1893). Type locality, "Bridger'g Pass." 



In the Sierra Nevada (Nos. 1666, 2068), and the White Mountains (No. 1799). 

 Nos. 1666 and 2068 differ from the other specimens, which belong to the typical 

 form of the species, in their more evenly glandular-serrate, purple-margined sepals 

 and their longer stylo, as well as in the white, not orange, color of the surface of 

 the root. 



Claytonia chamissoi Ledeb. in Spreng. Syst. Veg. i. 790 (1825). Type locality, 

 "Ins[ula] Aleut [ica]." 



In the high Sierra Nevada (Nos. 1582, 1618. 2122). The plant was always found 

 growing on nearly clean, fine gravel, over winch a thin stream of almost ice-cold 

 spring water was flowing. On the surface of the gravel and underneatli the matted 

 stems of the plant are produced, at the ends of slender rlagellae, an abundance of 

 white or pink tubers about as big as peas. In trying to disentangle single specimens 

 of the plant, the collector almost invariably breaks off these tubers. 



Claytonia perfoliata Donn in Willd. Sp. IT. i. 1186 (1798). Type locality, "in 

 America boreali." 



The plant was recorded from the Panamint Mountains, in Johnson (No. 561), Sur- 

 prise (No. 608), Willow Creek, and Mill canons; and from the Sierra Nevada, in the 

 valley of the Kaweah Kiver (No. 1370). In these localities it grew at the shaded 

 bases of cliff's and among rocks, near the lower limit of coniferous vegetation. 

 The plant makes an excellent pot-herb, and in tht Panamint Mountains was fre- 

 qnently used as such by the expedition. No. 561 has linear to oblsmceolate root- 

 leaves and glomerate inflorescence, varying toward C. apathulata Dougl. Its connate- 

 perfoliutn caulinc leaves and its large seeds, together with the place of its growth, 

 lead me to consider it an erratic form of C. perfoliata. 



Claytonia triphylla Wats. Proc. Amer. Acad. x. 345 (1875). Type locality, 

 "above Cisco, California." 

 Near Mineral King, Sierra Nevada (No. 1517). 



Montia fontana L. Sp. IT. i. 87 (1753). Type locality European. 

 Whitney Meadows, Sierra Nevada (No. 1619). 



Spraguea umbellata Torr. IT. Frem. 4 (1853). Type locality, "forks of the 

 Nozah Kiver, in the foot-hills of the Sierra Nevada of Northern California." The 

 Nozah Kiver is a branch of the Sacramento, west of Lassen Peak. '
