SOLANACEAE. 



VOL. III. 



connivent. Corolla yellowish or whitish, often with a darker brownish or purplish center, 

 open-campanulate, or rarely campanulate-rotate, plicate. Stamens inserted near the base of 

 the corolla; anthers oblong, opening by a longitudinal slit. Style slender, somewhat bent; 

 stigma minutely 2-cleft. Seeds numerous, kidney-shaped, flattened, with a thin edge, finely 

 pitted. [Greek, bladder, referring to the inflated calyx.] 



Probably 75 species, or more. Two are of European origin, and about half a dozen are natives 

 of India and Australia, the rest are American; about 30 occur in the United States. Type 

 species : Physalis Alkekengi L. 



* Annuals with branched fibrous roots. 



t Plants more or less pubescent (except in races of P. barbadensis.) 

 Fruiting calyx sharply s-angled, more or less acuminate at the summit and sunken at the base ; 



calyx-lobes (at flowering time) lanceolate or acuminate, as long as the tube or longer. 

 Leaves ovate, oblique, acute or acuminate, subentire at the base ; upper part repand or .suben- 



tire ; fruiting calyx small and short ; stem slender, diffuse, sharply angled. i. P. pubescens. 

 Leaver cordate, oblique, strongly sinuate to the base ; stem stout, obtusely angled ; fruiting 



calyx rounded. 2. P. pruinosa. 



Leaves cordate, scarcely oblique, more or less abruptly acuminate, acutely repand-dentate ; stem 



tall, acutely angled ; fruiting calyx larger, long-acuminate. 3. P. barbadensis. 



Fruiting calyx obtusely or indistinctly 5-io-angled; calyx-lobes (at flowering time) triangular, 

 generally shorter than the tube. 4. P. missouriensis. 



ft Plants glabrous, or the upper part sparingly beset with short hairs, or a little puberulent 



when young; fruiting calyx obtusely s-io-angled, not sunken at the base. 

 Corolla yellow, sometimes with the center a little darker but never brown or purple. 



Peduncles generally much longer than the fruiting calyx ; leaves sinuately toothed or subentire. 



5. P. pendula. 



Peduncles scarcely exceeding the fruiting calyx ; leaves sharply dentate. 6. P. angulata. 

 Corolla yellow, with a brown or purple center. 7. P. ixocarpa. 



** Perennial by thick roots and rootstocks. 



t Pubescence not stellate (although in P. pumila of branched hairs). 



Pubescence on the leaves none, on the upper part of the stem and the calyx sparse and short, if any. 

 Fruiting calyx ovoid, nearly filled by the berry, scarcely sunken at the base. 



Leaves ovate-lanceolate to broadly ovate, usually thin. 8. P. subglabrata. 



Leaves lanceolate, oblanceolate, or linear. 9. P. longifolia. 



Fruiting calyx pyramidal, very much inflated and deeply sunken at the base ; leaves broadly 



ovatu, usually coarsely dentate. 10. P. macrophysa. 



Pubescence sparse, consisting of flat, sometimes jointed, and in P. pumila branched hairs; in 



P. virginiana sometimes a little viscid. 

 Fruiting calyx ovoid, scarcely angled and scarcely sunken at the base ; leaves thick, obovate or 



spatulate to rhomboid, subentire. 



Leaves obovate or spatulate; hairs all simple. n. P.lanceolata. 



Leaves broader, often rhomboid ; hairs on the lower surface branched. 12. P. pumila. 

 Fruiting calyx pyramidal, more or less s-angled and deeply sunken at the base ; leaves ovate to 



lanceolate, generally more or less dentate. 13- P- virginiana. 



Pubescence dense, short, more or less viscid or glandular, often mixed with long flat jointed hairs. 

 Leaves large; blade generally over 2' long and more or less cordate. 14. P. heterophylla. 



Leaves less than 2' long, rounded ovate or rhombic, scarcely at all cordate at the base ; calyx, 



peduncles and younger branches with long white flat and jointed hairs. 15. P. comata. 

 Leaves small, i'-i^' in diameter, nearly orbicular, sometimes a little cordate at the base, not 

 coarsely toothed; stem diffuse or prostrate. 16. P.rotundata. 



tt Pubescence dense, cinereous, beautifully stellate. 17. P.viscosa. 



i. Physalis pubescens L. Low Hairy 

 Ground-Cherry. Fig. 3696. 



Physalis pubescens L. Sp. PI. 183. 1753. 



Annual; stem generally diffuse or spreading, 

 much branched, angled, often a little swollen at 

 the nodes, villous-pubescent or sometimes nearly 

 glabrous ; leaves thin, I'-ai' long, ovate, acute 

 or acuminate, at the base oblique, slightly cor- 

 date and generally entire, upward repand-den- 

 ticulate or entire, pubescent, sometimes becoming 

 nearly glabrous except along the veins ; peduncles 

 short, i "-2" long, or in fruit about 5"; calyx- 

 lobes narrow but not with a subulate tip; corolla 

 3"-S" in diameter, yellow with dark centre; an- 

 thers usually purplish ; fruiting calyx membra- 

 nous, io"-is" long, pyramidal, ovoid-acuminate, 

 more or less retuse at the base. 



In sandy soil, Pennsylvania to Florida, Arkansas 

 and California ; also in Mexico, the West Indies, 

 Central and South America and India. Called also
