SOLANACEiE. 225 



4. SALPIOHROA. Calyx 5-parted or 5-cleft ; the divisions narrow, herbaceous. Corolla 

 from tubular to (in ours) short-urceolate, 5-lobed; the lobes short, valvate-induplicate in 

 the bud. Stamens inserted high on the tube of the corolla ! Berry globular or oblong. 



5. ORYCTES. Calyx deeply 5-cleft ; the lobes narrow, herbaceous. Corolla short-tubu- 

 lar or oblong, 5-toothed ; the triangular lobes plicate in the bud, apparently erect. Sta- 

 mens inserted on the base of the corolla, included : filaments filiform, unequal : anthers 

 didymous. Berry apparently dry, globose, 10-20-seeded. Embryo apparently of this 

 tribe, but not seen mature. 



-I— -t— Calyx herbaceous and closely investing the fruit or most of it, not angled. 



6. OHAM.^SARACHA. Corolla rotate, 5-angulate, plicate in the bud. Filaments fili- 

 form : anthers oblong. Berry globose, filling the investing calyx, and its summit usually 

 more or less naked. Pedicels solitary in the axils, refracted or recurved in fruit. 



-1— H— -t— Calyx becoming much enlarged and membranaceous-inflated, enclosing the 

 fruit, reticulate-veiny, 



++ Five-toothed or lobed, vesicular in fruit : ovary 2-celled. 



7. PHYSALIS. Corolla rotate or rotate-campanulate, plicate In the bud, 5-angulate or 

 obscurely 5-lobed. Stamens not connivent. Calyx in fruit 5-angIed or 10-costate, and 

 the teeth or short lobes connivent, completely and loosely enclosing the juicy berry. 

 Pedicels solitary. 



8. MARGARANTHUS. Corolla urceolate-globose and 5-angular-gibbou8 above a short 

 narrow base, and with minutely 5-toothed contracted orifice, including the connivent 

 stamens. Otherwise as Physalis. 



++ +-I- Five-parted calyx connivent-vesictxlar in fruit : ovary 3-5-eelled. 



9. NICANDRA. Corolla open-campanulate, with entire or obscurely lobed border, 

 strongly plicate in the bud. Filaments filiform, included, dilated into a pubescent scale 

 at base. Calyx strongly 5-angled ; the scarious-raembranaceous and reticulated divisions 

 cordate-sagittate, the deflexed auricles at the sinuses acuminate. Fruit globose, dry or 

 nearly so at maturity. Pedicels solitary, recurved. 



Tribe II. ATROPE^. Corolla with the regular limb imbricated in the bud, the 

 sinuses little or not at all plicate. Stamens (4 or 5) all perfect. Baccate fruit 

 and seeds as in the preceding. 



1 0. L YCIUM. Calyx campanulate, irregularly 3-5-toothed or cleft, or somewhat truncate, 

 valvate or nearly so in the bud. Corolla from campanulate to tubular-funnelform or 

 salverform ; the lobes oblong or roundish, plane. Stamens often exserted : filaments 

 filiform: anthers short. Style flhform: stigma capitate or broadly 2-lobed. Berry 

 globular or oblong, subtended by the calyx, few-many-seeded, rather dry. Seeds reni- 

 form or rounded, flattened. Flowers either 5-merous or 4-merous. 



Tribe III. HYOSCYAME.E. Corolla with the limb either plicate or imbricated in 

 the bud. Stamens (5) all perfect. Fruit a capsule. Seeds and embryo as in the 

 preceding tribes. 



1 1 . DATURA. Calyx prismatic or tubular, 5-toothed, in ours at length circumscissile near 

 the base, the base remaining as a peltate border under the fruit (rarely splitting length- 

 wise). Corolla funnelform, with ample spreading border 5-10-toothed, convolute-plicate 

 in the bud. Stamens included or slightly exserted : filaments long and filiform. Style 

 long: stigma bilamellar. Capsule muricate or prickly (rarely smooth), commonly firm 

 and 4-valved from the top, sometimes fleshy and bursting irregularly at the top, 2-celled ; 

 the large many-seeded placentae projecting from the axis into the middle of the cells 

 and connected with the walls by an imperfect false partition, so that the ovary and fruit 

 are 4-celled except near the top, and the placentte as if borne on the middle of the 

 abnormal partitions. Seeds large, reniform-orbicular. 



12. HYOSCYAMUS. Calyx urceolate or tubular-campanulate with a 5-lobed limb, en- 

 larged and persistent, becoming many-costate and reticulate-veiny, enclosing the capsule. 

 Corolla short-f unnelform, with an oblique 5-lobed limb, plicate-imbricated in the bud ; 

 the lobes sometimes conspicuously unequal, those of one side being smaller ! Stamens 

 more or less exserted and declined. Style filiform : stigma capitate-dilated. Cap- 

 sule membranaceous, circumscissile towards the summit, which separates as a lid. Seeds 

 less flattened. 



Tribe IV. CESTRINE.(E. Corolla (usually elongated) with the regular limb in- 

 duplicate-valvate or induplicate-imbrioated in the bud. Stamens (mostly 5) all 

 perfect. Fruit either baccate or capsular. Seeds little or not at all flattened. Em-
