_ 240. M. (Barronta) ornata, Torr. § Gray, Fl. 1. p. 534,— Between the Rio 
Colorado (Upper Canadian) and Rock Creek; Aug. Petals, as in the fine specimens 
gathered by Fremont, &c., 23 inches long ; the stamens nearly 2 inches long and all fili- 
form. —I have never seen this species alive, nor does Mr. Fendler record the color of the 
flowers ; but Mr. Sprague, who observed it on the Missouri, confirms the uniform state- 
ment that the flowers are white, at most yellowish-white, and expand at sunset. I have 
raised the nearly allied M. nuda from seed, the flowers of which are said by Nuttall to be 
“of the same color” as those of M. ornata; and I observed the white corolla uniform- 
ly to open an hour or half an hour before sunset, and to remain expanded through the 
evening. On the other hand, the M. levicaulis of the interior of Oregon has yellow 
blossoms, which never expand in the evening, but during bright sunshine, according to 
Douglas: they are “ pale yellow,” according to Mr. Breckenridge: “they open during 
sunny hours, and are of a lurid golden-yellow,” according to Mr. Geyer. There is also 
an evident difference in the foliage, and in the foliose bracts, which are sparing in M. 
levicaulis; the latter has but five petals and five dilated filaments ; and although, indeed, 
Dr. Torrey assures me that these are sometimes replaced by five additional petals, still I 
cannot think that M. levicaulis should be merged in M. ornata, as has recently been done 
on the high authority of Sir Wm. Hooker.
