242 BOTANY. 



Southern California, Arizona and Sonera, probably as far northward as Ore- 

 gon. Frequent on the foot-hills and in the dry valleys from the Trinity 

 Mountains to the Wahsatch ; 4,300-5,000 feet altitude ; May, June. (850.) 



Eritrichiu'm Califoenicum, DC. DC. Prodr. 10. 130. Root slender, 

 annual ; stems weak, simple or usually diffusely branched, ascending, decum- 

 bent or prostrate ; pubescence appressed, strigose ; leaves linear or narrowly 

 oblong, acute or obtuse, ciliate, occasionally opposite and subsheathing ; ra- 

 cemes leafy at base, becoming much elongated ; flowers sessile or upon very 

 short pedicels ; calyx 5-parted, lobes lanceolate or linear, about equaling the 

 corolla, enlarging and spreading and subfoliaceous in fruit ; corolla white, with 

 5 yellow 2-parted scales on the throat, the lobes of the limb very obtuse ; 

 nutlets triangular, rugose. — A quite variable species, growing in muddy and 

 usually subalkaline localities ; stems J'-l° in length, the calyx ordinarily very 

 hispid with yellowish hairs. E. Chorisianum and E. Scouleri, with longer 

 pedicelled flowers, are considered a variety. E. connatifolium, Kell, is doubt- 

 less the same. From Washington Territory to Southern California, Arizona, 

 (Ives,) Colorado, and Northern Dakota, (Nicolet.) Frequent from the Wa- 

 shoe Mountains to the Wahsatch, both in the valleys and in the high canons ; 

 4r-9,500 feet altitude ; April-September. (851.) 



Eeitrichium GLOMEEATUM, DC. DC. Prodr. 10. 131. "Perennial" or 

 at least biennial; stem simple, erect, 6-18' high, usually solitary and rather 

 stout and rigid, very hirsute with spreading hairs, leafy especially at base ; 

 leaves 2-4' long, alternate, oblong- or linear-spatulate or oblanceolate, sub- 

 acute, hirsute and usually more or less appressed-pubescent ; spikelets 5-7- 

 flowered, lateral, axillary, clustered, more or less peduncled and usually 

 bifurcated or the upper ones sessile, often forming a narrow elongated spike- 

 like raceme, the subtending leaves often elongated-linear and conspicuous, as 

 are also the bractlets ; flowers 2-4" long, nearly sessile ; calyx very hispid, 

 5-parted, the linear-lanceolate lobes equaling the corolla-tube, becoming much 

 enlarged in fruit; limb of the white corolla broad and expanded, the trunca- 

 ted scales of the throat conspicuous; nutlets large, (1^" long,) ovate and nar- 

 rowed above but obtuse, more or less rugose and tuberculated, especially upon 

 the back, which is surrounded by an acute slightly raised margin, sulcate ven- 

 trally and attached to the elongated style to the middle.— A stout coarse 

 species, well-marked though somewhat variable. From Arizona (Ives) and 

 New Mexico northward to the ^Saskatchewan. Not seen in Nevada, and
