108 BOTANY OF THE DEATH VALLEY EXPEDITION. 



Lycium pallidum fliers, Ann. & Mag. Nat. Hist. scr. 2. xiv, 131 ( 1 85 J ) . Type 

 locality, "in Nova Mexico." 



Thi» specks was observed l>y Dr. Merrium and Mr. Bailey in tIio Beaverdain 

 Mountains, Utah (No. 1951), and in tlie. valley of the upper Santa Clara. 



Lycium torreyi Gray, Froc. Anier. Acad. vi. 47 (1861). Type localities, "Texas, 

 on the Rio Grande, to Fort Yuma, interior of California." 



In the valley of the Muddy River near St. Thomas, Lincoln county, Nevada (No. 

 1928), and at St. George, Utah (No. 1952). 



Datura nieteloides DC. Prodr. xiii. pt. i. 544 (1852). Type locality, "in calidis 

 Nova' Hispanhe regionibus." 



This -western representative of the eastern jimson weed occurred occasionally in 

 the desert, usually in cultivated and therefore moist ground. It was seen at Corn 

 Creek, Vegas Valley; in Johnson, Surprise, ami Hall canons, Panainiut Mountains; 

 near Lone Pine; and near Indian Wells. In the intramontane region it was of 

 common occurrence in similar situations. 



Nicotiana attenuata Wats. Bot. King Surv. 276(1871)— Torr. MS. Type localities, 

 "near Carson City," "Lake W T ashoe," "Fort Tejon," points in Nevada and Cali- 

 fornia. 



Near Crystal Spring, Coso Mountains (No. 913). This species is characteristic 

 of, if not entirely confined to, the Great Rasin and desert regions. In intramontane 

 California it appears to be replaced by A', b'ujelorii, but a sutheient amount of material 

 to decide this question was not collected. 



Nicotianatrigonophylla Dunaliu DC. Prodr. xiii. pt i. 562(1852). Type locality, 

 "in Mexico ad Aguas calicntes," State of Aguas Calientes. 



This plant is a common one in canons of the desert mountains. Specimens were 

 collected in the Funeral Mountains, near Saratoga Springs (No. 255), and in Johu- 

 Ron Canon, Panamint Mountains (Nos. 515, 549). In No. 255, a winter specimen with 

 mature fruit, the capsules are one-half exceeded by the calyx, a character attrib- 

 uted to V. palmeri. In the whole region examined by the survey this plant oc- 

 curred only in canons or steep rocky slopes, and was invariably a slightly sntf'rutes- 

 cent perennial. Other specimens from western Mexico and Lower California exhibit 

 the same tendency, although the species is described as annual. 



CSROPHULARIACEJE. 



Mohavea breviflora sp. no\ . Pt.atk XVII. 



Annual; stem simple, or branched from the base, 12 cm. or less high; leaves 1 to 4 

 cm. long, oblong-lanceolate, acuminate at the apex, tapering at the base into a mar- 

 gined petiole; calyx lobes linear-oblong, obtuse or bluntly acute, about Id mm. in 

 length; corolla 18 to 20 mm. long, its lobes entire or slightly undulate; lower lip 5 

 to 7 mm. long above the yellow palate, cleft nearly to it; palate pubescent over 

 nearly its entire surface; seeds 2 to 2.5 mm. long; otherwise resembling Mohavea 

 vixcida. 



Type specimen in the United States National Herbarium, No. 547, Death Valley Ex- 

 pedition, collected April 1, 1891, in Johnson Canon, Panamint Mountains, California, 

 by Frederick V. Coville and Frederick Funston, 



This plant may bo distinguished readily from M. riscida by its smaller size, shorter 

 and broader leaves, and proportionally much shorter corolla limb. M. viscida grows 

 20 to 30 cm. high and has a corolla 30 to 35 mm. long, erose denticulate lobes, and 

 lower lip 18 mm. long above the palate, the sinuses reaching only to within 10 or 12 

 mm. of that organ. The corolla of M. viscida is conspicuously purple-dotted and has
