2CG NIGHTSHADE FAMILY. 



I. NOLANA FAMILY, with few or many separate ovaries 

 collected in a circle or heap around the ba-e of a single style. Low 

 and spreading plants. 



1. XOLAXA. Calyx 5-cleft, foliaceous. Corolla short and open funnel-form, 



plaited in the'bnd. Stamens 5. Style 1: stigma capitate or club-shaped. 

 Ovaries 3-40, becoming 1-4-celled drupelets or nutlets, each cell 1 -seeded. 



II. NIGHTSHADE FAMILY PROPER, with only one 2-celled 

 or sometimes 3 5-celled ovary as well as style, the many-seeded 

 placentae in the axis, usually much projecting into the cell. 



1. Corolla u-heel-shaped, lobed or parted into 5 or sometimes more divisions, plaited 

 and valvnte or the margins turned inwards in the bud: the tube ctry short : 

 antliers conniving around the style : fruit a berry. 



2. LYCOPERSICUM. Like Solanum, except that the anther? are united by a 



membrane at their tips and the cells open lengthwise. Leaves pinnately 

 compound. 



3. SOLAKUM. Stamens with anthers equalling or mostly longer than the very 



short filaments, usually not united, the cells opening by a hole at the apex. 

 (Lessons, p. 101, fig. 204, 205.) Leaves simple or pinnate. 



4. CAPSICUM. Stamens with slender filaments much longer than the short and 



separate commonly heart-shaped anthers, their cells opening lengthwise. 

 Berry sometimes dry and inflated, then becoming 1-celled. 



2. Corolla between wheel-slinped and funnel-form, pi. tiled in the. but/, the border very 

 moderately if at aU lobed J antker$ ttpiratf, opening le.iiijtkioi.st : caljx blad- 

 dery-inflated after flowering, enclosing the global ir berry. 



5. PHYSALIS. Calyx 5-cleft. Corolla mostly somewhat 5-lobed. (Lessons, p. 



101, fig. 206.) Stamens erect. Fruit a juicy, ot'<ea edible, 2-ccllc:l berry. 



6. NICANDRA. Calyx 5-parted and angled, 'the divisions somewli.it arrow- 



shaped. Corolla with widely-spreading border almost entire. Fruit a dry 

 3 -5-celled berry. 



3. Corolla bell-slurped, funnel-form, tubul'tr, or salver-shaped: anthers separate, 



opening lengthwise : c.dyx not bladdery-inflated. 

 * Qilyx urn-shtpi'd in fruit, enclosing the pod' corolla considerably irregular. 



7. HYOSCYAMUS. Calyx 5-lobed, the spreading border becoming reticulated, 



enclosing the 2-celled pod, which opens by the top failing oil' as a lid. Co- 

 rolla short funnel-form, with the plaited' border more or less oblique and 

 unequal. Stamens declined. 



* Ctlyx 5-parted to near the base, the lobes fdiaceous. 



8. ATROPA. Calyx with ovate divisions, in fruit c-.ilarrrn^ and spreading under 



the globose purple berry. Corolla between bell-shaped' and funnel-form, with 

 5 triangular-ovate lobes. Stamens and style somewhat declined, slender. 



9. PETUNIA. Calyx with narrow somewhat spatnlate lobe* much longer than 



the tube. Corolla funnel-form or somewhat salve-shaped, the 5-lobed border 

 commonly a little unequal. Stamens included in the tube, unequal. 1'od 

 2-celled, 2-valvcd. 



* * * Calyx lubul'ir, prismatic, or bell-shaped, 



- Covering the dry pod or newly so : corolli s'lfaer-shaped or funnel-form, the lobes 



plaited in the bud : seeds minute. 



10. XIEREMRERC.IA. Corolla with very slender thread-like tube ^'-1'long), 

 abniptly expanded at the narrow throat into a saucer-shaped or almost wheel- 

 Bhaped 5-lobed border. Stamens short, borne on the throat. Stigma kidney- 



shaped and somewhat 2-lippod. Flower^ scattered. 

 NICOTIANA. Corolla with a resriilar 



11. NICOTIANA; Corolla with a regular n-lohed border. Stamens inserted on its 



tube, included: filaments straight. Stigma capitate. Pod 2-4-vaIved from 

 the apex. Flowers more or less raccmed or panicled. 



*- *- Cdyx prigmntic., fulling aioay after flowering, leering the 2 -4-celledpod naked. 



12. DATURA. Corolla funnel-form, strongly plaited in the bud, and with 5 or 



more ixnnted teeth. (Lessons, p. 100, fig. 199; p. 110, fig. 226.) Filaments
