rower, narrowed and oblique at base, margins entire or repand-denticulate, 

 alternate or paired, 6-10 cm. long: peduncles slender, 1-2 cm. long: calyx 

 glabrous or nearly so; the lobes ovate to lanceolate-triangular, about equal- 

 ing the tube: corolla with purplish throat, rather large: anthers tinged with 

 purple: fruiting calyx somewhat 10-angled, sunken at the base, becoming 

 filled with the red berry. Scarcely in our range; extending eastward to the 

 Atlantic. 



4. Physalis longifolia Nutt. Trans. Am. Phil. Soc. II. 5: 193. 1834. Per- 

 ennial from a thick rootstock; stem usually stout and tall, 4-8 dm. high,

 to lanceolate or broader, subentire or repand, short-petioled : peduncles 1-2 

 cm. long, in fruit often recurved: calyx generally glabrous, with triangular- 

 lanceolate lobes as long as the tube: corolla large, yellow with dark center: 

 anthers yellow, tinged with purple: fruiting calyx ovoid, about 3 cm. long, 

 not sunken at the base: berry yellow, the lower portion and the stipe gluti-

 with brownish center: calyx commonly strigose or villous, the lobes triangular- 

 lanceolate; in fruit ovoid, not sunken at base, slightly 10-angled: berry 

 greenish-yellow. Common in our range; widely distributed eastward. 



6. Physalis polyphylla Greene, Pitt. 4: 150. 1900. A nearly glabrous 

 perennial 1-3 dm. high; stem angular, scabrous, puberulent: leaves 2-4 cm. 

 long, very numerous, notably feat her- veined with white fine veins, lanceolate 

 to linear, glabrous except for the strigillose margins and veins: peduncles 1 

 cm. long, deflexed in fruit: corolla greenish-yellow, with dark green spots: 

 fruiting calyx broadly and acutely ovate, reticulate, the teeth whitish- 

 puberulent. Southern Colorado. 



7. Physalis pumila Nutt. Trans. Am. Phil. Soc. II. 5: 193. 1834. Near 

 the two preceding: leaves thicker, generally broadly ovate and acute at both 

 ends, often somewhat rhomboid, entire or nearly so, rather larger, on petioles 

 15-25 mm. long, strigose with many-branched hairs, especially on the lower 

 surface: calyx hirsute, in fruit oblong-ovoid, somewhat sunken at the base. 

 From Colorado eastward to the Missouri. 



8. Physalis heterophylla Nees. Linnaea 6: 463. 1831. Perennial from 

 creeping rootstocks, diffusely much branched, or at first erect, villous-sub viscid 

 with flat jointed hairs, 3-8 dm. high: leaves oblong to cordate, moderately 

 thick, 4-6 cm. long, sinuate-toothed to subentire: corolla 15-20 mm. broad, 

 yellow: calyx long- villous, the lobes lanceolate, usually shorter than the 

 tube: anthers yellow: berry yellow. P. virginiana. Common in our range 

 and extending far eastward. 



9. Physalis hederaefolia Gray, Proc. Am. Acad. 10: 65. 1874. Erect or 

 at length diffuse, densely viscid-pubescent or on young parts more or less 

 villous: leaves roundish-cordate or almost reniform, or sometimes ovate, 

 coarsely and obtusely angulate-toothed, 18-36 mm. in diameter: corolla about 

 12 mm. broad, on pedicels 4-8 mm. long: calyx finely viscid-pubescent; in 

 fruit angled, ovoid, 20-30 mm. long. Southern Colorado and southward to 

 Mexico. 



K). Physalis rotundata Rydb. Mem. Torr. Bot. Club 4: 352. 1896. Per- 

 ennial, freely and horizontally long-branched from the base up, about 2-3 dm. 

 hitrh, broader than high, closely and finely granular-glandular or glandular- 

 pubescent, very leafy: leaves broadly ovate or subrotund, coarsely and ir- 

 regularly dentate, obtuse or acute, 2-4 cm. long, on petioles usually less than 

 OIK- fourth as long: peduncles slender, shorter than the fruiting calyx, divar- 

 icate to ileflexed: calyx-lobes triangular-lanceolate, in blossom longer than 

 the tube; fruiting calyx dilated, globose, 25-30 mm. in diameter, distinctly 

 angled, finely reticulate-veined, sunken at base: berry yellowish, 12-15 mm.
