ONAGRACES. 
CENOTHERA cespitosa. Torr. and Gr., fl. 1., p.500. (Evening Primrose.) Shores and 
Islands of Great Salt Lake, Major Stansbury. 
Var. montana. C4. montana, Nutt. in Torr. and.Gr., fl. 1, p. 500. Stemless and cexs- 
pitose; leaves lanceolate, sinuate-toothed, tapering into a petiole, expanding at base; mar- 
gins quite woolly; flowers large, white and red. As Dr. Torrey remarks at page 387 of 
Stansb. Report, the three species of Nuttall forming the group Pachylophis of Spach, should 
be thrown into one species. They seem to differ only by the capsule being nearly sessile 
in @. cespitosa; quite sessile, in @. montana and pedicellate in @. marginata. Valley of 
the Great Salt Lake, Mrs. Carrington. 
dG. . . . albicaulis, Nutt. in Torr. and Gr., fl. 1, p. 495. One foot high or more, 
erect, branching at top, glabrous, whitish; leaves narrow-lanceolate, mostly entire or re- 
motely toothed: flowers axillary, rather small, white, drying purple. Islands and Valley 
of the Great Salt Lake. June. Major Stansbury and Mrs. Carrington. 
Gi. . . . Scapoidea, Nutt. in Torr. and Gr., fl. 1, p.506. A very diminutive plant 
with a few ovate radical leaves, obscurely denticulate, on a petiole about the length of 
the limb; scape 3—4 inches, usually naked, bearing 6—13 very small flowers on slender 
pedicels with minute bracts. Capsule very large in proportion to the flower. Western 
shores of the Salt Lake. May. Major Stansbury. 
GAYOPHYTUM ramosissimum. Torr. and Gr., fl. 1, p. 513. A small and divaricately 
branched plant with very small flowers at the extremity of the branches, resembling those 
of enothera scapoidea; capsule short, linear-clavate, shorter than the capillary pedicels. 
Antelope Island. Major Stansbury. 
LOASACEA. 
Menrze.ta albicaulis. Dougl.in Torr. and Gr., fl. 1, p. 534. Bartonia albicaulis. Hook, 
fl. Bor. Am., 1, p. 222. Stem white and polished, branching from the base, nearly gla- 
brous below, leaves lanceolate, deeply sinuate-pinnatifid, sessile, remote; flowers small, 
not bracteolate, yellow. <~Valley of the Great Salt Lake. Major Stansbury. 
M. . . . Ornata. Torr. and Gr., fl. 1, p. 534. Bartonia ornata. Nutt. Stem
