runners : radical and lower cauliue leaves rhombic-obovate, acutish, about half incli long, 

 contracted at base into slender petiole ; upper narrower and small (3 to 2 lines long), when 

 fresh subclavate : Howers few and racemose : jjetals obovate or somewhat obeordate, 4 or 5 

 lines long, very much surpassing tlie rounded sepals, rose-color, varying to white. — Clay-

 northward to Juneau, Alaska, Miss Cooley, and soutli in tlie ISierra Nevada and Coast Uange, 

 California, to the Yosemite. The bulblet-like jji-opagula or offshoots, borne in the axils of 

 the cauline leaves, are not commonly seen in the liried specimens. A variety from M'ash- 

 ington, Suksdor/] with obovate obtuse chiefly radical leaves and filiform branches, differs 

 from the next only in its smaller flowers and less leafy stem. 

 M.* flagellaris, Rohinson, n. comb. Apparently less fleshy, and with broadly ovate or 

 uliovaif lfa\('s, the weak stems a foot long, sparingly branched, the branches apparently 

 attenuate into a kind of stolon or stoloniform peduncle : petals over half inch long. — C/cii/-

 growing in deep shade. Prof. Macoun (Cat. Canad. PI. ii. 311, 312) reports the collection 

 of an identical or closely similar plant in the bed of Eagle Kiv., Brit. Columbia (also called 

 "C. sarmentosa, Bong.").

 ■i— Leaves broad and long-petioled, in the way of Stellaria media : stamens 5 : seeds closely 



lineate and the elevated lines closely and transversely lineolate ! 



M.* diffusa, Greene, 1. c. A span or two high, diffusely dichotomous, leafy, the weak stems 

 at flrst erect : leaves broadly deltoid-ovate or uppermost oblong-ovate, inch or less long, 

 abruptly contracted into a petiole of about equal length (lower occasionally opj)Osite) : inflo- 

 rescence subcymose, several-flowered ; pedicels slender, spreading : calyx a line or two long, 

 surpassed by the white or pale rose-colored petals : style long. — Clui/tonia diffusa, Nntt. in

•i- -»— Narrow-leaved annuals (lower nodes of the stem sometimes rooting) with racemose 



inflorescence secund and pedicels recurved after flowering : leaves partly scarious and 



clasping at insertion : stamens 3 : seeds lenticular, thin-edged, very smooth : petals (white 



or tinged with rose) obviously unequal, but narrowed or unguiculate to distinct or more 



or less connate bases. 



M.* linearis, Greene, 1. c. A span or two high, erect or soon diffuse : leaves linear-filiform 



and fleshy, inch or two long, about a line wide throughout, or obscurely widened upward : 



sepals in fruit 2 lines long or nearly so, rounded : seeds large (a line in diameter), very black 



and shining. — Claijtouia linearis, Dougl. in Hook. Fl. Bor.-Am. i. 224, t. 71 ; Torr. & Gray,

Columbia to middle parts of California, and east to Montana and the Yellowstone; first coll. 



by Douglas. 



M.* dichotoma, Howell, 1. c. 36. An inch or two high, more diffuse or depressed but 



not repent, smaller in all parts : leaves similar but smaller, linear or nearly so : racemes 



terminal, rather dense, and numerou.sly flowered : sepals in fruit only a line long : seeds 



half or third of a line in diameter, somewhat shining or rather dull at maturity. — Clai/-

California; first coll. by Nutlall. 



M.* Ho"Wellii, Watson. Similar in habit, but still more dwarf, rooting at the lower nodes : 



leaves spatulate : inflorescences several, few-flowered, axillary, subtended by ovate scale-like
