984 SOLANACEAE 



teeth, thin, 4-7 cm. long ; nerves not prominent ; petioles slender, 2-4 cm. long : peduncles 

 slender, 2-3 cm. long, erect, often reflexed at maturity, but seldom exceeding the fruiting 

 calyx in length : calyx glabrous ; lobes triangular to lanceolate, generally shorter than the 

 tube : corolla 5-10 cm. in diameter : anthers more or less purplish tinged : fruiting calyx 

 about 3 cm. long, ovoid, not prominently 5-10-angled, sometimes purple-nerved and at 

 length nearly filled with the yellow berry. 



In rich soil, North Carolina to Texas, Central America, Brazil and the West Indies. Also in India. 



10. Physalis ixocarpa Brot. Annual, glabrous or nearly so. Stems at first erect, 

 later widely spreading, much branched, angled, the younger parts often sparingly hairy : 

 leaf-blades cordate to ovate and cuneate at the base, which is somewhat oblique, sinuately 

 dentate or entire, 3-6 cm. long : peduncles 2-5 mm. long : calyx sparingly hairy ; lobes 

 broadly triangular, shorter than the tube : corolla bright yellow with purple throat, 1-1.5 cm. 

 (sometimes nearly 2 cm.) in diameter : fruiting calyx rounded ovoid, obscurely 10-angled, 

 often purple-veined, at maturity often filled with the purple berry, which sometime* 

 bursts it. 



In loose soil, Texas to California and Mexico. Also introduced in Massachusetts, Virginia and 

 Washington. 



11. Physalis Philadelphica Lam. Annual, glabrous or nearly so. Stems 0.5-1.5 

 m. tall, angled, dichotomously branched, glabrous or sometimes slightly pubescent with 

 sparse and short hairs on the upper parts : leaf-blades ovate to ovate-lanceolate, often very 

 oblique at the base and more or less acuminate, entire or repand-denticulate, 6-10 cm. 

 long ; petioles 4-6 cm. long : peduncles slender, often in pairs, 1-2 cm. long, generally longer 

 than the flower : calyx glabrous, or minutely ciliolate ; lobes ovate-lanceolate or triangular, 

 sometimes broadly ovate and unequal, generally equalling the tube : corolla yellow or 

 greenish yellow with purplish throat, 1.5-2.5 cm. in diameter : anthers tinged with pur- 

 ple : fruiting calyx at first somewhat 10-angled and sunken at the base, at maturity often 

 filled with or even burst by the large red or purple berry. 



In rich soil, Rhode Island to Kentucky, Georgia and Texas. 



12. Physalis subglabrata Mackenzie & Bush. Perennial from a thick rootstock, 

 glabrous or sparingly hairy with short appressed hairs. Stems stout, 3-9 dm. tall, 

 branched, glabrous or the upper part with short hairs on the angles : leaf -blades ovate or 

 ovate-lanceolate, 2.5-7.5 cm. long, 1.25-5 cm. wide, undulate or entire, oblique and 

 rounded or subcordate at the base, glabrous or with a few scattered hairs on the veins : 

 calyx 6-8 mm. long, appressed-hairy on the veins and at the base ; lobes triangular, about 

 the length of the tube : corolla yellow with a darker center, 10-15 mm. broad : fruiting 

 calyx ovoid, slightly depressed at the base, slightly angled : berry globular, stiped. 



In loose soil, along railroads, in fields and river bottoms, Ontario to Nebraska, Arkansas and Ten- 



13. Physalia longifolia Nutt. Perennial from thick rootstocks, almost glabrous. 

 Stems in the common form stout and tall, 0.5-1 m. high, slightly angled, branched above ; 

 branches strict, glabrous : leaf-blades lanceolate, oblanceolate or linear, tapering into a 

 stout short petiole 1-2 cm. long, nearly entire or repand : peduncles 1-2 cm. long, in fruit 

 often recurved : calyx generally glabrous ; lobes triangular-lanceolate, about the length of 

 the tube : corolla 1-2 cm. in diameter, yellow with a dark commonly brownish 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 glutinous. 



In rich soil, on prairies and plains, Iowa to Montana, Texas and Mexico. 



14. Physalis Texana Kydb. Perennial from deep rootstocks, glabrous. Stems 

 angular and striate, somewhat fleshy, diffuse : leaf-blades broadly ovate, generally very 

 oblique at the base and decurrent on the long-margined petiole, somewhat fleshy, entire or 

 slightly wavy and with the veins prominent on the lower surface : peduncles about 1 cm. 

 long, scarcely longer than the corolla, at maturity 2-3 cm. long : calyx-lobes broadly ovate- 

 triangular, about the length of the short tube : corolla lemon-yellow with dark spots, 2-2. 5 

 cm. in diameter, very villous in the throat : anthers yellow : fruiting calyx about 3 cm. 

 long, ovoid, indistinctly 10-angled, not sunken at the base : berry purplish. 



In rich soil, southern Texas. 



15. Physalis macrophysa Kydb. Perennial, almost glabrous, the rootstock rather 

 thick and fleshy. Stems 0.5-1 m. tall, comparatively slender, angled, perfectly glabrous, 

 or the upper parts sparingly pubescent with very short hairs : leaf-blades thin, 4-8 cm. 

 long, 2-5 cm. wide, the lower obtuse, the upper acute or acuminate, on slender petioles 

 2-4 cm. long : peduncles 1-1.5 cm. long, erect, reflexed at maturity : calyx glabrous ; 

 lobes ovate-triangular or broadly lanceolate, generally a little shorter than the tube :
