a line or two long, from oval or obovate to oblonf? or spatulato, or on vigorous 

 shoots 3 lines long and almost linear : flowers nearly sessile or on pedicels of one 

 or two lines in length : tube of the white corolla included in the campanulate 

 4-toothed calyx, its 4 oval rotately spreadhig lobes hardly a line long. 



Near San Diego, on clay-hill slopes, Nuftnll (without llowei-s). Cooler, Cleveland. The 

 flowers barely 2 lines long, on slender sliort pedicels in Dr. Cooper's specimen, but nearly sessile 

 in those of Mr. Cleveland ; the plants otherwise similar. Foliage apparently as llcsliy as in L. 

 Ccurolviiamun. 



4_ ^ Corolla a third to half an inch in length. 



4. L. Fremontii, Gray, 1. c. Minutely soft-puberulent, 2 to 4 feet high : leaves 



spatulate, 4 to 9 lines long : pedicels not longer than the oblong-campanulate or 

 cylindraceous caly^ : corolla white with some purplish, tubular, 4 to 6 lines long, 

 5dobed, the lobes ovate and very short : hlaments nearly naked. 



California or Nevada ? Fremont, 1849 (the station unknown). There is a var. (?) Bigclovii, 

 Gray, with shorter flowers, in Arizona. 



5. L. Torreyi, Gray, 1. c. Glabrous, 3 to 8 feet high : leaves nearly spatulate 

 or oblancuolate, G to 14 lines long: pedicels usually as long as the calyx (2 Hues 

 long) : corolla white or tinged with purple, 5 or 6 lines long, tubular-funnelform 

 gradually enlarging from base to summit, with 4 or 5 short and broad spreading 

 Tobes, the edges of these minutely tomentose : fdaments woolly at base : berries 

 red, "not edible." — Parry in Am. Nat. ix. 348. 



Southeastern borders of the State, lower part of the Rio Colorado to S. Utah, on low saline 

 flats, Thomas, Cooper, Parry, &c. Extends eastward to the borders of Texas. 



6. L. Andersonii, Gray. Eesembles the preceding; but is lower, 2 to 4 feet 

 high, smallerdeaved, very abundantly flowered; the Avhite corolla narrower and 

 more tubular, 5 hues long, its limb only 2 or 3 lines wide, and its short rounded 

 lobes with naked edges : pedicels and calyx only a line long : berries bright red, 

 or amber-colored, "ripening a month earlier than those of the preceding, edible. — 

 Proc. Am. Acad. vii. 388 ; Watson, Bot. King Exp. 275 ; Parry, 1. c. 



Kocky hills in the desert region, borders of S. Nevada {Anderson) to Utah ( Watson, Parry) ; not 

 certainly known within the limits of the State.— Var. IFrif/hfii, Gray, is a more leaty and 

 sparsely flowered form, with smaller flowers, collected by C. WrujU and E. Palmer in Anzona, 

 and perhaps to be found on the Rio Colorado. 



8. DATURA, Linn. Stramonium. Thorn-Applk. 

 Calyx prismatic or tubular, 5-toothed, deciduous after flowering by a transverse 

 separation near the base, which persists as a circular plate under the fruit. Corolla 

 fuunelform, with an ample expanded border which is strongly 5-plaited and the 

 plaits convolute in the bud. Stamens mostly included : filaments long and filiform : 

 anthers opening lengthwise. Style long : stigma 24ipped. Capsule thickish, 

 prickly or muricate all over, with 2 proper cells, each divided more or less by 

 a false partition which bears the two broad transverse placentos across its middle. 

 Seeds very numerous, rather large, reniform. Embryo slender and coiled. — 

 Plants (our species coarse herbs), of rank odor and narcotic-poisonous qualities; 

 with ovate petioled leaves, and solitary mostly large flowers in the forks of the 

 stem, on short peduncles, produced through the season. Corolla commonly white 

 or tinged with violet, sometimes fragrant.
