common throughout the desert region in the Lower Sonoran zouo. Specimens were

NYCTAGINACEiE. 



Mirabilis frcebellii (Behr) Free. Cal. Acad. i. 69 (1855), under Oxylaphvs; Greene 

 Bull. Cal. Acad. i. 124 (1885). Type specimens, "cnlta e seminibus a J. Frcebel 

 prope Warner's Ranch lectis." Warner's ranch was an old stage station on the 

 wagon road between Fort Yuma and San Diego, about 5 kilometers west of tho 

 present station of Aguas Calicntes, San Diego County, California. 



The plant occurred in Willow Creek Canon, Fanamint Mountains (No. 761); be- 

 tween Kecler and Crystal Spring; near Indian Wells; abundantly in Antelope Valley, 

 west of the yucca belt; and in the southern part of the Tulare Plains. From the 

 data furnished by the expedition, the zonal position neither of this plant nor of M. 

 multijiora is clear. 



Mirabilis laevis (Benth.) Bot. Snlph. 44 (1844), under OriibapJnis; Curran, Proe. 

 Cal. Acad. ser. 2. i. 235 (1889). Type locality, "Bay of Magdalena." 



The plant of the Mohave Desert region, our No. 741, which may be distinct, has 

 white flowers, while its intramontane representative, our No. 1018, has red flowers 

 and more nearly spherical fruit. Both have passed under tho name M. calif ornica, 

 but the specific name Icevis is older. 



The species was recorded at Resting Springs; in the northern end of Resting 

 Springs Valley; near Winters's ranch, Pahrump Valley; in the Funeral Mountains, 

 west of Amargosa; in Johnson, Surprise, and Willow Creek canons, Funeral 

 Mountains; in Shepherd Canon, Argus Mountains (No. 741); in a canon of the Inyo 

 Mountains, near Swansea; between Kecler and Crystal Spring; at St. George (No. 

 1956); and on Sarcobatus Flat, west side of the Ralston Desert, Nevada (No. 1996). 

 At all these stations which lie well within the desert, the flowers of (he plant when- 

 ever they were seen were white. The red-flowered form was observed on the east 

 slope of Walker Pass (No. 1018), and at the western end of Tehachapi Canon. 



Mirabilis multiflora (Torr.) Ann. Lye. N. Y. ii. 237(1828), under Oxylapkw; Gray, 

 Bot. Mex. Bound. 169 (1859). Type locality, "about tho Forks of the Platte." 



Specimens were observed near Calieute, Kern County, California, and at Beaver- 

 dam, Arizona (No. 1937).

 bluntly acute at the apex, green above, much paler beneath, hirsute with weak

 nute, ovate-lanceolate, ciliate; flowers in clusters of 2 to 5 terminating the branches,
