274 PORTULACACEiE. Moniia. 



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

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

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

 spreading or reflexed : flowers roseate, rather show}' ; calyx often with reddish tinge : seeds 

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

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

 (The thoughtless publication of new combinations in such irregular and obscure documents 

 merits severe censure.) Claytonia arenicola, Henderson, Bull. Torr. Club, xxii. 49; Holzin-

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

 Lyall, Henderson, Bingen, Suksdurf; Idaho, Spalding, Sandberg, Henderson ; fl. April to 

 June. Nearest M. gypsophiloides, but of different range and readily distinguished by its 

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



^— H— 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, Brandegee, in litt. Small and dense, succulent : root annual, subsimple, slen- 

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

 lines broad, rounded at the apex, and somewhat narrowed at the subsessile base ; cauline 

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

 sulrambellate ; pedicels equalling or exceeding the short scape-like stem : sepals suborbicular, 

 2 lines in diameter : roseate petals twice as long : valves of the capsule 1^ to 2 lines in lengtli : 

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

 slopes of Snow Mountain, Lake Co., and on Yolo Bolo, California, Brandegee. Forming 

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

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



M.* perfoliata, Howell, 1. c. 38. Ratlier 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, 

 commonly 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.

 Mex.), northward to Brit. Columbia, common near the coast; first collected by Menzies, 

 now a weed of cultivation in many parts of the world. 



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

 radical leaves spatulate to filiform-linear, when narrow u.sually an elongated blade and 

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

 almost disjoined : 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, vei-y obscurely if at 

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

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

 ovate or rhomboidal and petiolate, as in C. perfoliata ; blades sometimes broader than long ; 

 cauline usually small and partly disjoined, subtending sessile and glomerate or suliumbellate 

 inflorescence of small flowers : calyx only a line long. — Claytonia parviflora, var. depressa.
