 sometimes tinged with purple : fruiting calyx 3-4 cm. long, 2.5-3 cm. in diameter, pyram- 

 idal to ovoid-conic, indistinctly 10-angled, deeply sunken at the base : berry small, in

16. Physalis lanceolata Michx. Perennial, sparingly hairy, the rootstock appar- 

 ently, as a rule, slender and creeping. Stems about 5 dm. tall, at first erect, later spreading 

 or diffuse, only slightly angled, sparingly hirsute with flat hairs : leaf-blades broadly ob- 

 lanceolate or spatulate, tapering into the petiole, acute or obtuse, nearly always entire, 

 rarely wavy, but not sinuately toothed, thickish, sparingly pubescent with short hairs : 

 peduncles 1-2 cm. long, in fruit reflexed : calyx strigose or villous, rarely glabrous ; lobes 

 triangular-lanceolate: corolla dullish yellow with a brownish center, about 1.5 cm. in 

 diameter : fruiting calyx rounded ovoid, not sunken at the base, indistinctly 10-angled : 

 berry yellow or greenish yellow. 



On dry plains, North Carolina to Wyoming, South Carolina and New Mexico, 



17. Physalis piimila Nutt. Perennial from slender rootstocks, 0.5-1 m. high, hirsute. 

 Stems obscurely angled : leaf-blades thick, generally broadly ovate, acute at both ends and 

 somewhat rhomboid, the lower often obtuse and obovate, generally much larger than in 

 the preceding species, 5-10 cm. long, entire or seldom sinuate, on petioles 2-3 cm. long at 

 maturity : calyx densely hirsute, not stellate ; lobes triangular, generally a little shorter 

 than the tube : corolla yellow with brown center, 1.5-2 cm. in' diameter : fruiting calyx 

 generally more elongated than in the preceding, 4-5 cm. long, oblong-ovoid, a little 

 sunken at the base, indistinctly 10-angled. 



On plains and prairies, Missouri to Colorado and Texas. 



18. Physalis Virginiana Mill. Perennial from a somewhat fleshy rootstock, pu- 

 bescent. Stems 0.5-1 m. tall, dichotomously branched, somewhat angular, pubescent with 

 appressed hairs, sometimes somewhat glandular, or in some forms nearly glabrous : leaf- 

 blades ovate-lanceolate, tapering to both ends, 3-6 cm. long, generally more or less sinu- 

 ately dentate, often yellowish green : peduncles 1-2 cm. long, generally erect, or becoming 

 curved, but scarcely reflexed : calyx strigose-hirsute, or at least puberulent ; lobes tri- 

 angular or broadly lanceolate, nearly equalling the tube in length": corolla sulphur-yellow 

 with purplish spots, 1.5-2.5 cm. in diameter : anthers yellow : fruiting calyx pyramidal- 

 ovoid, 5-angled and sunken at the base : berry reddish. [P. lanceolata Chapm., not Michx. 

 -P. monticola Mohr. ] 



In loose soil, New York to Manitoba and Colorado, south to Florida and Louisiana. 



19. Physalis rigida Pollard & Ball. Perennial from a thick rootstock, resembling 

 in habit P. subghbrata. Sterns strict, angled, more or less branching, 3-4 dm. tall, hispid- 

 pubescent with flat hairs, especially above : leaf-blades firm, ovate-lanceolate, wavy-mar- 

 gined, densely pubescent when young, tapering at both ends : calyx pubescent with flat 

 hairs, especially on the veins and at the base : lobes triangular: corolla 1-1.5 cm. wide, 

 yellow with purple center : fruiting calyx ovoid, nearly glabrous, obscurely 10-angled, 2.5-3 

 cm. long, somewhat retuse at the base. 



In waste grounds, Louisiana to Arkansas and Tennessee. 



20. Physalis intermedia Kydb. Perennial, puberulent, and sometimes a little viscid 

 when young. Stems 3-8 dm. tall, dichotomously branched, angled and striate, the upper 

 portion with longer hairs and somewhat viscid : leaf -blades ovate or ovate-lanceolate, acute, 

 4-6 cm. long, often oblique at the base, slightly sinuately toothed or nearly entire, very 

 thin, light green, puberulent or glabrate : peduncles 1-2 cm. long, recurved at maturity, 

 hairy : calyx puberulent or hirsute with appressed hairs ; lobes broadly lanceolate, about 

 equalling the tube : corolla sulphur-yellow with purplish spots, 1-2 cm. in diameter : 

 anthers yellow : fruiting calyx ovoid, 'slightly 5-angled and slightly sunken at the base. 

 [P. Virginiana intermedia Bydb. ] 



In dry soil, Pennsylvania to Indiana, southward to Florida and Texas. 



21. Physalis arenicola Kearney. Perennial from slender horizontal rootstocks, 

 sparingly hairy. Stems 2-4 dm. tall, diffuse, striate, light green, the pubescence mostly 

 of simple hairs, but sometimes a little glandular, in age deciduous except on the nerves 

 of the calyx : leaf-blades relatively small, 1.5-6 cm. long, but sometimes 8 cm., ovate-cor- 

 date, truncate or cuneate at the base, irregularly angulate-dentate, pubescence, if any, 

 along the veins, which are generally prominent and conspicuously reticulated : peduncles 

 slender : calyx-lobes triangular-lanceolate, equalling the tube in length : corolla 1.5-2 cm. 

 in diameter, light yellow : anthers yellow : fruiting calyx 3 cm. long, narrowly ovoid or 

 rather oblong-pyramidal or nearly cylindric, conspicuously reticulated : berry light yellow.
