7. DATtfRA L. JAMESTOWN or JIMSON WEED. THORN APPLE 



Calyx prismatic or cylindrical, 6-toothed, separating transversely above the 

 base in fruit, the upper part falling away. Corolla funnel-form, with a large 

 and spreading 5-10-toothed plaited border. Stigma 2-lipped. Capsule globular, 

 prickly, 4-valved, 4-celled except near the 2-celled top. Seeds rather large, 

 Hat. Rank weeds, narcotic-poisonous, with ovate leaves, and large showy 

 flowers produced all summer and autumn on short peduncles in the forks of the 

 branching stem. (Altered from the Arabic name, Tntorah.) 



1. D. STRAMONIUM L. (STRAMONIUM.) Annual, glabrous; leaves ovate, 

 sinuate-toothed or angled ; stem green; calyx prismatic; corolla white, 7-9 cm. 

 long, the border with 5 teeth ; lower prickles of the capsule mostly shorter. 

 Waste grounds ; a well-known ill-scented weed. (Nat. from Asia ?) 



2. D. TATULA L. (PDRPLE T.) Mostly taller; stem purple; corolla pale 

 violet-purple ; prickles of the capsule nearly equal. Waste grounds, Atlantic 

 States to Ont., Minn., and south westw. (Nat. from Trop. Am.) 



3. D. METEL L. Pubescent ; leaves entire or slightly toothed ; calyx tubular ; 

 corolla 1.5-2 cm. long; capsule evenly prickly. Waste ground, etc., becoming 

 frequent. (Adv. from Trop. Am.) 



8. NICOTlANA [Tourn.J L. TOBACCO 



Calyx tubular-bell-shaped, 5-cleft. Corolla funnel-form or salver-form, usu- 

 ally with a long tube ; the plaited border 5-lobed. Stigma capitate. Capsule 

 2-celled, 2-4-valved from the apex. Seeds minute. Rank acrid-narcotic herbs, 

 mostly clammy-pubescent, with ample entire leaves, and racemed or panicled 

 flowers. (Named after Jean Nicot, who was thought to have introduced 

 Tobacco, N. Tabacum L., into Europe.) 



1. N. RSTICA L. (WILD TOBACCO.) Annual ; leaves ovate, petioled ; 

 tube of the dull greenish-yellow corolla cylindrical, two thirds longer than the 

 calyx, the lobes rounded. Old fields, N. Y. and Ont., westw. and southw. ; 

 a relic of cultivation by the Indians. (Of unknown nativity.) 



N. LONGIFLORA Cav., with long slender tubular corolla, is said to escape from 

 cultivation. 



SCROPHULARlACEAE (FIGWORT FAMILY) 



Chiefly herbs (rarely trees'), with didynamous stamens (or perfect stamens 

 often only 2, rarely 5) inserted on the tube of the 2-lipped or more or less 

 irregular /corolla, the lobes of which are imbricated in the bud; fruit a 2-celled 

 and usually many-seeded capsule, with the placentae in the axis; seeds anatro- 

 pous or amphitropous, with a small embryo in copious albumen. Style single ; 

 stigma entire or 2-lobed. Leaves and inflorescence various, but the flowers 

 not terminal in any genuine representatives of the family. A large family 

 of bitterish plants, some of them narcotic-poisonous. 



SUBFAMILY I. ANTIRRHINOfDEAE 



Upper lip or lobes of the corolla covering the lower in the bud (with occasional 

 exceptions in Mimulus, etc.). Capsule usually septicidal. 



Tribe I. VERBASCEAE. Corolla rotate. Flowers racemose. Leaves alternate. 



1. Verbascum. Stamens 5, all with anthers, and 3 or all with bearded filaments. 



tribe II. ANTIRRHf NEAE. Corolla tubular, with a spur or sac at the base below, the throat 

 usually with a palate. Capsule opening by chinks or holes. Flowers In simple racemes or 

 axillary. Lower leaves usually opposite or whorled. Stamens 4. 



2. Linaria. Corolla spurred at base ; the palate seldom closing the throat. 



3. Antirrhinum. Corolla merely saccate or gibbons at the base ; the throat nearly or quite 



closed by a conspicuous palate.
