IL NIGHTSHADE FAMILY propbr, with only one 2-celled 

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

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



§ 1. Corolla loheel-skaped^ hbed or parted into 5 or gometimes nu)re dim^lons^ plaited 

 and valvnte or the mar<iins turned inwards in the dud: tile tube very short : 

 antJters conniimtg around the style : fruit a berry. 



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



membrane at their tips and the cells open lengthwise. Leaves pinnat'ely 

 compound. 



3. SOLANUM. 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. CAPSICUil. 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 whedl-sliaped and funnel- form^ plaited in the bud, the border very 

 moderately if at all Itibcd; anthers sep'irate, openinrj lengthwise: calyx blad- 

 dery-inflated after flmoering, enclosing the ghbular berry. 



5. PHySALIS. Calyx 5-cleft. Corolla mostly somewhat 5-lobed. (Les.sons, p. 



101, fig. 206.) Stamens erect. Fruit a juicy, often edible, 2-ceIled beny. 



6. NICANDRA. Calyx 5-parted and angled, the divisions somewhat arrow- 



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

 3 - 5-celled beiTy. 



§ 3. Corolla bcll-shnped, fumiel-form, tubular, or salver-shaped: anthers separate, 

 opening lengthwise : c dyx not bladdery-inflated. 

 » Cdyx urn-sh:iped in fruit, enclosing the pod: corolla considerably irregular. 



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

 enclosmg the 2-cellcd pod, which opens by the top falling off as a lid. Co- 

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

 unequal. Stamens declined. 



* Calyx 5-parted to near the base, the lobes foliaceous. 



8i ATKOPA. Calyx with ovate divisions, in frait enlarging and spreading under 

 the globose purple berry. Corolla between bell-shaped and fnnnel-fonn, with 



. „^t57txt'S1 "^Y'® -t ^'"■'"''"s 'i"il style somewhat declined, slender. 



tt / i k^%^ "1- i'^'™^ somewhat spatulate lobes miich longer than 

 the tube. Corolla funnel-foi-m or somewhat salvei--shupert, the 6-lobed border 

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

 2-celled, 2-valved. 



# * » Calyx tubular, jmsmatic, or bell-shaped, 

 H- Covering the dry pod or nearly so : corolla, salver-shaped or funnel-form, the lobes 

 plaited in the bail : seeds minute. 



10. N1ERE5IBERGIA. Corolla with vevv slender thread-like tube (4'-l'lon^), 



abrupjyc.xpanded at the narrow throat into a saucci-shaped or almost wheel- 

 shaped 6-iobed border. Stamens short, borne on the tlu-oat. . Stigma kidney- 

 11 ,„«/;»Kv^'i"ii somewhat 2-lipped. Flowers scattered. 



11. JN ICO 1 lANA. Corolla -with a regular 5-lobed border. Stamens inserted on its 



tune, mcluded: filaments straight. Stigma capitate. Pod 2 - 4-valved from 

 the apex. Flowers more or less racemed or panicled. 



1- +-, Calyx prismatic, falling away after flowering, leaving the 2-i-cettedpod naked. 



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



more iiomted teeth. (Lessons, p. 100, fig. 199; p. 110, fig. 225.) Filaments
