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. 



.Claytmiifl sihirir.a T. 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. 



Clavtonia 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, Macoun\ 

 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.
