140 PORTULACACEAE. 



flowered, with few or no bracts; pedicels slender; petals white, pellucid, 10-12 

 mm. long; capsule longer than the sepals; seeds bright, shiny, 1-1.5 mm. broad. 

 In cold woods along streams in the mountains. 



Claytonia sibirica L. Stems simple, erect or ascending, 15-40 cm. high; 

 basal leaves ovate, 2-6 cm. long, contracted into long margined petioles; 

 cauline pair ovate, sessile but not united; raceme bracteate, loose, the flowers 

 on long pedicels; petals white or pink with red veins, about 6 mm. long; seeds 

 granulate. 



In wet meadows and open moist woods, very common. 



Claytonia spathulata Dougl. Annual, 2-10 cm. high, erect or spreading; 

 basal leaves linear or somewhat spatulate, thickish; cauline leaves usually 

 united on but one side or completely united and the disk narrower on one side, 

 or rarely separate and sessile; racemes short, few-flowered; pedicels 6-8 mm. 

 long; sepals ovate; petals white or pink, 3-4 mm. long, twice as long as the 

 sepals; seeds black, shining, appearing minutely roughened under a lens. 



In moist soil especially where somewhat saline; not common. 



Claytonia spathulata exigua (Torr. & Gr.) Piper. Basal leaves narrowly 

 linear, 1-5 cm. long; cauline linear, usually somewhat dilated at base and con- 

 nate on one side. 



In moist places, rare. 



Claytonia perfoliata Donn. Annual, branched from the base, 10-50 cm. 

 high, erect; basal leaves long-petioled, the blades usually rhomboid-ovate, 

 but varying to spatulate-linear; cauline leaves united, forming an orbicular 

 or somewhat angled disk, 3-5 cm. broad; racemes rather loose, one-sided; 

 calyx 4 mm. long; petals smaller, white; seeds smooth, shiny, lenticular, 2 mm. 

 broad. 



Very common. A form with the cauline leaves distinct is C. perfoliata 

 amplectens Greene. 



Claytonia parviflora Dougl. Annual, branched from the base; stems usually 

 15-30 cm. high, erect; radical leaves long-petioled, linear, lanceolate or 

 spatulate; cauline pair united into an orbicular somewhat angled disk, 1-4 cm. 

 in diameter; raceme usually loose, interrupted, somewhat one-sided; calyx 

 2 mm. long; petals pink or white, about twice as long; seeds shiny, usually 

 smooth, 1 mm. broad. 



In prairies or "burns." 



Claytonia parviflora depressa Gray. Small and depressed, more fleshy; 

 whole plant commonly reddish; cauline leaves sometimes nearly separate; 

 radical leaves broadly ovate. 



In open places. 



Claytonia chamissoi Ledeb. Perennial, with slender elongate stolons, 

 finally tuberiferous at the apex; flower stems mostly simple, 10-30 cm. tall; 

 leaves 3-7 pairs, broadly spatulate, 2-4 cm. long; raceme few-flowered; 

 pedicels slender; petals pale or white, 6-8 mm. long; stamens 5; capsule equal- 

 ing the calyx; seeds kidney-shaped, minutely roughened. 



Moist copses, rare in our limits. Comox, Vancouver Island, Maconn; 

 Roy, Washington, Allen. 



Claytonia parvifolia Moc. Fleshy perennial, producing slender creeping 

 stolons, 'and propagating by leafy offsets produced in the axils of the cauline 

 leaves; lower leaves obovate, acutish, short-petioled, 1-3 cm. long; cauline 

 leaves reduced and narrower; racemes few-flowered; sepals suborbicular, 2 

 mm. long; petals pink with darker veins, 8-10 mm. long. 



In moist places especially on rocks in the mountains.
