Sir William Hooker thinks that M. IctvicaulU is not distinct from this species; but Dr. Gray states ( 1. c.) that it differs in its yellow flowers, which open in the sunny hours, while in M. ornate they are white, and open toward sunset. M. ALBICAULIS, Dougl.; Torr. and Gr. 1. c.- Valley of the Salt Lake. ERODIUM CICUTARIUM, L'Herit.- Islands of the Salt Lake. Fl. June. This plant is widely spread oyer the western part of North America, from the Rocky Mountains to the Pacific, and is doubtless indigenous. HEUCHSRA RUBEBCBNS, Torr. ( sp. nor.)- Scapo nudo glabro vel scabriusculo; foliis suborbicularibus breviter 5- 7- lobatis glabrius-culis, lobis orenato- dentatis, dentibus setoso- mucronatis, vel obturis; panicula oblongo; thyrsoidea sublaza; staminibns exsertis; petaliB linearibus calyce « quali longioribus. Stansbury's Island, Salt Lake. Fl. June 26. Rhizoma thick and somewhat ligneous, clothed with brown Vestiges of leaves. Leaves an inch or an inch and a- half in diameter, nearly orbicular, mostly cordate at the base, somewhat coriaceous, either wholly glabrous or very sparingly strigose- pubescent, moderately 5- 7- lobed, and the lobes crenate, or broadly toothed. The teeth usually xnueronate and sometimes ciliolate. Petioles 2- 4 inches long. Scapes varying from a span to fifteen inches high, entirely naked, except a few remote appressed scales. Panicle rather loose and few ( 15- 20) flowered. Flowers about one- third larger than in JET. amerieana. Blacts lanceolate and often toothed. Calyx purplish red, campanulate, pubescent; the segments linear- oblong, obtuse, and nearly equal. Petals narrowly linear, persistent* about as long as the stamens. Styles much exserted. This species has the foliage of H> parvifolioj the inflorescence of JET. hiepida, and the calyx of E. amerieana. Plate V. Heuchera rubeecens, of the natural size. Fig. 1, a flower.
