986 SOLANACEAE 



22. Physalis ciliosa Rydb. Perennial from slender creeping rootstocks. Stems up- 

 right, branched, 2-3 dm. tall, terete, scarcely striate, together with the pedicels and 

 calyxes ciliate with long and white jointed hairs : leaf-blades 4-7 cm. long, ovate, truncate 

 or slightly cordate at the base, nearly entire or with a few coarse teeth, sparsely hairy on 

 the nerves, long-petioled, thin and not conspicuously veiny : peduncles very slender : calyx 

 turbinate, resembling that of P. arenicola: corolla funnelform-campanulate, apparently 

 without dark markings : fruiting calyx ovoid-pyramidal, sunken at the base. 



In sandy soil, Tennessee to Georgia and Florida. 



23. Physalis sinuata Rydb. Perennial, villous and viscid. Stems decumbent, 

 striate and angled, villous with long flat hairs and very viscid : leaf-blades_ rounded ovate, 

 very oblique at the base and often subcordate, pubescent with long flat hairs especially on 

 the veins, dark, obtuse, undulate, sinuate : peduncles about 1 cm. long, long-villous : calyx 

 densely villous with flat hairs and viscid ; lobes triangular-lanceolate, about equalling the 

 tube : corolla yellow with darker spots : fruiting calyx and berry unknown. 



In sand, Florida. Summer. 



24. Physalis ambigua (A. Gray) Britton. Perennial, villous, scarcely at all viscid. 

 Stems 3-8 dm. tall, light green, slightly angled, villous with long flat hairs : leaves with 

 the finer pubescence sparse ; blades over 5 cm. long, thin, light green, round-ovate or cor- 

 date, somewliat sinuately toothed or nearly entire, acute, but rarely acuminate : peduncles 

 1-2 cm. long, long-villous like the calyx : calyx-lobes triangular, generally shorter than 

 the tube : corolla 1.5-2 cm. in diameter, yellow with dark spots : anthers generally purple : 

 fruiting calyx ovoid, somewhat svmken at the base : berry yellow. 



In rich soil, especially in thickets, Vermont to Iowa, south to Virginia and Tennessee. 



25. Physalis nyctaginea Dunal. Perennial from slender horizontal rootstocks. 

 Stems puberulent and villous with long flat hairs and somewhat viscid, generally zigzag, 

 decumbent and spreading, and branched, slightly angled : leaf-blades dark green, ovate, 

 often oblique, but very rarely cordate at the base, more or less acuminate, mostly entire, or 

 occasionally sinuately dentate and rather thick, sparingly hairy, not at all puberulent ; the 

 long hairs often confined to tlie veins of the lower surface : peduncles long-villous, 1-2 cm. 

 long, reflexed in fruit : calyx villous ; lobes triangular, shorter than _ the tube : corolla 

 1-1.5 cm. in diameter, yellow with darker spots: anthers yellow: fruiting calyx ovoid, 

 5-angled and sunken at the base : berry yellow. 



In dry soil, Rhode Island to Iowa and south to Georgia and Louisiana. 



26. Physalis heterophylla Nees. Perennial from slender creeping rootstocks. Stems 

 0.5-1 m. tall, erect, or later generally decumbent and spreading, viscid and glandular, 

 villous with moderately long jointed flat hairs : leaf-blades generally over 5 cm. long, 

 generally broadly cordate, often acute but very rarely with an acumination, thick, more or 

 less sinuately toothed, or sometimes subentire : pubescence short and fine with a mixture 

 of longer flat jointed hairs : calyx long-villous ; lobes triangular, 'generally shorter than the 

 tube: corolla 1-1.5 cm. in diameter : anthers generally yellow : berry yellow. 



In loose, rich soil, especially in fields, New Brunswick to Saskatchewan, Florida, Texas and 

 Colorado. 



27. Physalis comata Rydb. Perennial. Stems about 5 dm. tall, pubescent with 

 fine and short hairs, those on the calyx, peduncles and upper branches mixed with long, 

 white, flat, jointed hairs; quite similar to P. heterophylla Nees, but leaves smaller ; blades 

 not over 0.5 dm. long, rounded ovate, scarcely at all cordate at the base, about 5 cm. long, 

 thin, somewhat repand-dentate or nearly entire ; petioles as long as the blades :_ peduncles as 

 long as the fruiting calyx or longer : corolla mainly greenish yellow, brown in the center, 

 1.3-2 cm. in diameter : fruiting calyx as in P. hederaefolia but thinner in texture, 3-4 

 cm. long, rounded ovoid, somewhat lO-angled, scarcely sunken at the base. 



On the plains, Nebraska and Colorado to Texas. 



28. Physalis hederaefolia A. Gray. Perennial. Stems erect and branched, rarely 

 decumbent, 3-5 cm. higli, from a thick caudex, finely viscid-pubescent or villous, the hairs 

 generally short : leaf-blades in the typical form broadly cordate or subreniform, coarsely 

 and angulately sinuately toothed, more or less 3-5-ribbed, about 3-5 cm. in diameter : 

 peduncles generally short, but in one form (P. Palmeri A. Gray), a little longerthan the 

 fruiting calyx : calyx finely viscid-pubescent : corolla about 1.5 cm. wide: fruiting calyx 

 ovoid, 5-10-angled, pubescent, 2-3 cm. long. 



In dry soil, Texas, Colorado and Arizona, south to Mexico. 



29. Physalis mollis Nutt. Perennial from horizontal rootstocks. Stems 3-6 cm. 

 high, densely Avhitish or grayish tomentose with stellate pubescence : leaf-blades I'ounded 

 cordate or the upper broadly ovate, coarsely sinuately toothed : peduncles 2-4 cm. long oi
