200 NIGHTSI1AIM-: FAMILY. 



I. NOLAXA FAMILY, with few or many separate ovaries 

 collected in a circle or heap around the base of a single style. Low 

 and spreading plants. 



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



plaited in the bud. Stamens 5. Style 1: r-tigma capitate or eliil>--haped. 

 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 ;J-f>-celled ovary as well as style, the many-seeded 

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



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

 and valuate or the mart/ins turned inwards in the bud: the tube very short : 

 anthers conniving around the style : fruit a berry. 



2. LYCOPERSICUM. Like Solatium, except that the anthers are united by a 



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

 compound. 



3. SOLANl'M. 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. 90, fig. 2{)2, 253.) Leaves simple or pinnate. 



4. CAPSICUM. Samens 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-cclled. 



2. Corolla between wheel-shnptd and funnel-form, pi tiled in the bud, the border n ry 

 moderately if at (dl lubed . anthers separate, opening lengthwise: calyx blad- 

 dery-inftuted after Jiwoering, enclosing the globular berry. 



5. PHYSALIS. Calyx 5-cleft. Corolla mostly somewhat 5-lobed. Stamens 



erect. Fruit a juicy, often edible, 2-celled berry. 



6. XICAXDHA. Calyx 5-parted and aimled, the divisions somewhat arrow- 



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

 3-5-cellcd berry. 



3. Corolla belt-shaped, funnel-form, tuhulir, or sulccr-shaped ; anthers separate. 



opening lengthwise : c dyx nut bl.idd< ry-inftaled, 

 ft Culijx urn-shaped in fruit, enclosing iliepcd- corolla considerably irregular. 



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



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

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

 unequal. Stamens declined. 



* Calyx ^-parted to near the base, the lobes fuliaceous. 



8. ATROPA. Calyx with ovate divisions, in fruit enlarging 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 spatulatc lobes much longer than 



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

 commonly a little unequal. Stamens included in the tube, unequal. Pod 

 2-celled, 2-valved. 



* * * Calyx tubular, prismatic, or In-U-shaped, 



-t- Covering the. dry pod or urnr/if $n : rornlf-i tt'ili'fr-fliiiped or funnel-form, the lobes 

 pi 'iti il in the. bud : jii-K/s mi n ut i\ 



10. NIERKMP,r,I;TA. Corolla with very .-lender thread-like tube ^'-1'long), 



abruptly expanded at the narrow throat into a BEUCer-shaped or almost wheel- 

 shaped Vi-lobed border. Stamens short, borne on the throat. Stigma kiduey- 

 shaped ami somewhat 2-lipped. Flowers scattered. 



11. NICOTIAXA. Corolla with a regular r.-lolied border. Stamens inserted on its 



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

 the apex. Flowers more or less racemed or panicled. 



-- -- Gilijx prismatic, falling atoay after flowering, lea ring the 2 - ^-celled pod naked. 



12. DATURA. Corolla funnel-form, strongly plaited in the bud, and with 6 or 



more pointed teeth. ( Lessons, p. 89, fig. 246; p. 98, fig. 282.) Filaments
