10. DATURA L. 



Tall narcotic herbs, some tropical species shrubs or trees, with alternate petioled 

 leaves, and large solitary erect short-peduncled white purple or violet flowers. 

 Calyx elongated-tubular or prismatic, its apex 5-cleft or spathe-like, in the follow-

 capsule. Corolla funnelform, the limb plaited, 5 -lobed, the lobes broad, acuminate. 

 Stamens included or little exserted; filaments filiform, very long, inserted at or 

 below the middle of the corolla-tube. Ovary 2-celled, or falsely 4-celled; style 

 filiform; stigma slightly 2-lobed. Capsule 4-valved from the top, or bursting 

 irregularly. [The Hindoo name, dhatura.] About 12 species, of wide distribu- 

 tion. The following are introduced weeds. 



Glabrous or very sparingly pubescent; leaves lobed, calyx prismatic. 



Stem green; flowers white; lower prickles of the fruit shorter, i. D. Stramonium. 



Stem purple; flowers lavender or violet; prickles about equal. 2. D. Tatula. 

 Finely glandular-pubescent ; leaves entire; calyx tubular. 3. D. Met el. 



1. Datura Stramonium L. STRAMONIUM. JAMESTOWN OR JIMSON-WEED. 

 THORN-APPLE. (I. F. f. 3222.) Annual, glabrous or the young parts sparingly 

 pubescent; stem stout, 3-15 dm. high. Leaves thin, ovate, acute or acuminate, 

 mostly narrowed at the base, 0.7-2 dm. long, irregularly sinuate-lobed, the lobes 

 acute; flowers white, about I dm. high; calyx prismatic, less than one-half the

 and waste places, N. S. to Fla., Minn, and Tex. Nat. from tropical regions, 

 probably from Asia. June-Sept. 



2. Datura Tatula L. PURPLE THORN-APPLE. PURPLE STRAMONIUM. 

 (I. F. f. 3223.) Similar to the preceding but usually a little more pubescent; 

 stem commonly more slender, purple ; leaves almost like those of D. Stramoniiim, 

 but rather darker green or with a tinge of purple; flowers lavender colored or 

 violet, or the tube nearly white. In fields and waste places, Ont. to Minn.,
