Datura. SOLANACE.E. 543 



a line or two long, from oval or obovate to oblong or spatulate, 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 spreading lobes hardly a line long. 



Near San Diego, on clay-hill slopes, Nuttall (without flowers), Cooper, Cleveland. The 

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

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

 Carol 'in ianum. 



+- -t- 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 calyx : corolla white with some purplish, tubular, 4 to 6 lines long, 

 5-lobed, the lobes ovate and very short : filaments nearly naked. 



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

 Gray, with shorter flowers, in Arizona. 



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

 or oblanceolate, 6 to 14 lines long: pedicels usually as long as the calyx (2 lines 

 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 

 lobes, the edges of these minutely tomentose : filaments 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. Resembles the preceding ; but is lower, 2 to 4 feet 

 high, smaller-leaved, very abundantly flowered ; the white corolla narrower and 

 more tubular, 5 lines 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. 



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

 certainly known within the limits of the State. Var. Wrightii, Gray, is a more leafy and 

 sparsely flowered form, with smaller flowers, collected by C. Wright and E. Palmer in Arizona, 

 and perhaps to be found on the Rio Colorado. 



8. DATURA, Linn. STRAMONIUM. THORN-APPLE. 



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 

 funnelform, 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 2-lipped. Capsule thickish, 

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

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

 Seeds very numerous, rather large, reniforrn. 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. 



Chiefly natives of tropical America, but now widely diffused over the world. There is a section, 

 Erugmansia, consisting of soft-wooded arborescent or shrubby plants, with pendulous flowers of 

 huge size, of which the commonest is D. ARBOREA, the Tree Stramonium, not rare in cultivation, 

 and which may stand the winter without protection in the southern part of the State. Our 

 wild or spontaneous species are herbs, with the flower erect.
