M.* arenicola, A. A. Heller. Much more sleuderyet approaching in habit var. heterophi/lla 

 of the preceding species: stems numerous, 2 to 6 inches high: radical leaves lauce-oblong 

 to spatulate linear, the cauline similar : raceme loose, elongated ; pedicels slender, widely 

 spreading or reHexed :. Howers roseate, rather showy : calyx often with reddish tinge : seeds 

 black, half line in length, very smooth and shining, scarcely more than half as large as in 

 the ])receding species. — [List of] Idaho Plants, 1896, on the second [unnumbered] page.

 merits severe censure.) Clai/tonia arenicola, Henderson, Bull. Torr. Club, xxii. 49; llolzin-

 xxii. 282, iu part. — Along creek-bottoms and on stony land, Washington, near ISpokane, 

 Lyall, Henderson, Bingen, Suksdorf; Idaho, Spalding, Sandbery, Henderson ; H. April to 

 June. Nearest M. gi/psophiloides, but of different range and readily di-stinguished by its 

 much more decidedly bracteate racemes, and much more slender elongated cauline leaves. 



^— -t— Bracts few and minute or none : leaves succulent ; the cauline pair usually connate : 

 flowers apparently opening for 2 or more days : species or forms (except the first) conflu- 

 ent in a series. 



M.* saxosa, Braxdegee, in litt. Small and dense, succulent : root annual, subsimple, slen- 

 der, perpenilicular : radical leaves broadly spatulate or obovate, .3 to 6 lines long, 2 to 3 

 lines brt>ad, rounded at the apex, and somewhat narrowed at the subsessile base ; cauline 

 leaves a single pair, ovate, obtuse, quarter inch or less in length, not connate : flowers 

 subumbellate ; pedicels etiualling or exceeding the short scape-like stem : sepals suborbicular, 

 2 lines in diameter : roseate petals twice as long : valves of tlie capsule 1 1 to 2 lines in length : 

 seeds large, black, foveolate-striate. — Claytonia saxosa, Brandegee, Zoe, iv. 150. — Shaly 

 slopes of Snow Mountain, Lake Co., and on Yolo Bolo, California, Brander/ee. Forming 

 " dense succulent balls, 1 to 3 inches iu diameter " and rather well marked among the re- 

 lated forms by its short and broad scarcely petiolate radical leaves. 



M.* perfoliata, How^ell, 1. c. 38. Rather large and coarse, green and often reddening in 

 age, a span to a foot high : radical leaves from subreniform or rhomboidal to .spatulate- 

 obovate (commonly 1 to 3 inches broad), petiolate; cauline connate into an entire or often 

 angulately 2-lobed rounded disk: pedicels short, seldom longer than the fruiting calyx, 

 coTnmonly in 3 or 4 pairs or fascicles in a short interrupted and secund raceme, sometimes 

 all or a part closely clustered close to the disk : sepals orbicular, in fruit commonly 2 lines 

 long and broader than the capsule : petals white, little surpassing the calyx : seeds turgid- 

 lenticular, very shining, but at maturity minutely granulate, the larger a line long or more.

M.* parviflora, Howell, 1. c. More slender, green or glaucescent, a span or two high : 

 radical leaves spatulate to filiform-linear, when narrow usually an elongated blaile and 

 shorter petiole ; cauline a rounded disk as of the preceding, or rarely the rounded leaves 

 almost di.sjoined : pedicels slender, in fruit 2 to 6 lines long and much longer than the 

 (about line long) calyx, less fascicled, more commonly scattered in a looser raceme, but 

 sometimes inflorescence all glomerate on the disk : petals white or pale rose-color, hardly 

 double the length of the calyx : seeds half as large as in the foregoing, very obscurely if at 

 all granulate. — Clai/tonia parviflora, Dougl. in Hook. Fl. Bor.-Am. i. 225, t. 73; Torr. &

Var.* depressa, Robinson, n. comb. Mostly small, depressed : radical leaves broadly 

 ovate nr rhomhciidiil and petiolate, as in C. perfoliata; blades sometimes broader than long; 

 cauline u.sually small and partly disjoined, subtending sessile and glomerate or subumbellate 

 inflorescence of small flowers: calyx only a line long. — Clai/tonia parviflora, \aT. depressa.
