A small genus, mostly confined to the inteiior of North Ameiica, incUuling two northern 

 Asiatic species besides the following. 



1. M. chenopodioides, Moquin. Branched from the base: stems 3 to 12 

 inches long, asiuMuliiig, leafy : leaves lanceolate-hastate or sometimes narrowly sputu- 

 late, a half to one inch long, entire or sparingly sinuate-dentate, acute or obtuse, 

 cuneate or attenuate at base, the upper nearly sessile ; lower petioles elongated : 

 Hower-clusters dense, often reddish : sepal flesliy and foliaceous, oblanceolate or 

 spatulate, often much exceeding the fruit : pericarp fleshy, becoming dry and 

 minutely pitted, adherent : seed lenticular, or often reniform with a curved embryo, 

 tlie margin acutish, half a line long. — DC. Prodr. xiii^. 85, excl. var. ; Watsun, 

 llev. Chenop. 102. Blitam cheiiopodtoiJes, Nutt. 



Throughout the interior, from the Saskatchewan to Northeastern California, Texas and Arizona ; 

 Sierra County, Levimon. 



2. M. spathulata, Gray. Eesembling small specimens of the last ; leaves all 

 narrowly oblanceolute or spatulate, half an inch long or less, entire: flowers smaller; 

 sepal rarely exceeding the fruit : pericarp minutely papillose, separating from the 

 minute shining seed, which is less than a quarter of a line broad. — Proc. Am. 

 Acad. vii. 389 ; Watson, 1. c. 



In tlie Sierra Nevada ; at Mono Pass {Bolander) and in Sierra County, Lemmon. 



3. M. pusilla, Torrey. Very slender, erect, dilfusely and dichotomously much 

 branched from the base, 2 to 6 inches high, often reddish : leaves oblong, oljtuse, 

 entire, scarcely petioled : flowers solitary or few iu the clusters, minute : se])als (1 

 to 3) much shorter than the fruit and evanescent : pericarp thin, adlierent, minutely 

 tuberculate : seed less than a quarter of a line broad. — Watson, Bot. King Exp. 

 291 ; Rev. Chenop. 102. 



On the dry alkaline flats of Northwestern Nevada, and doubtless of Northeasteru California ; 

 a very distinct and interesting species. 



6. ROUBIEVA, Moipiin. 

 Flowers perfect or pistillate, witliout bracts. Periantli deeply campanulate, 

 3-5-toothed, at length saccate and contracted over the fruit, 3-5-nerved and net-

1. R. multifida, Moquin. Prostrate or ascending, branching and leaf}'- ; stems 

 a foot long or more : leaves lanceolate to linear, -^ to 1| inches long, acute, dee])ly

 small. —DC. Prodr. xiii^. 80 ; Watson,' 1. c. 99.
