No. 7900, collected May 30, in a meadow about two miles 

 northeast of Redding, Shasta county. Here the plants were 

 growing among tall grass and other herbs and consequently 

 of a taller and stricter growth, about 3 dm. high. 



Moiitia obtiisata 



Apparently perennial: the caudex ascending, prolonged 

 into a thick (3 mm.) sterile shoot 5 or 6 cm. long: stems many 

 from the base of the caudex, slender, ascending, 2 dm. high, 

 leafy, their bases enlarged and membranous: leaves veined, 

 those on the sterile shoots obovate or oblanceolate 3 cm long in- 

 cluding the petiole, 6 or 7 mm. wide, the petiole about 12 mm. 

 long, 2 or 3 mm. wide; lower stem leaves like those of the ster- 

 ile shoots but smaller, those above gradually becoming fewer 

 and smaller, reduced to linear sessile bracts; leaf axes, especially 

 the upper ones, bearing deciduous leafy buds: pedicels filiform, 

 ordinarily under 2 cm. in length: sepals round-obovate, 2 mm. 

 across: flowers few, racemose, white or pinkish, about 7 mm. 

 long, the petals obovate, 3 or 4 mm. wide across the blunt top 

 which is cut for about 2 mm. by a V-shaped notch: seeds ovoid 

 or fig-shaped, black, rather dull, marked by innumerable small 

 pits. 



The type is no. 7945, collected June i, 1905, oti moist 

 banks near Shasta Retreat, Siskiyou county. This is mostly 

 the Montia parvifolia of recent authors, at least as to the Cali- 

 fornian plant, but the original of that Alaskan species had 

 "foliis enerviis," and "petalis acute a«d breve bifidis."
