P. "Wrightii, Gray. Annual, a span high, widely branched, nearly glabrous ; the ap- 

 pressed and rather sparse pubescence on pedicels and young parts very short and mi- 

 nute : leaves oblong or lanceolate-oblong, sinuate-toothed or repand, acute at base, about 

 an inch long : pedicels filiform, longer than the flower and the fruiting calyx : corolla over 

 half uich in diameter, apparently pure white : anthers with or without a tinge of violet : 

 fruiting calyx half inch long, nearly filled by the berry: — S. W. Texas, on prairies of the 

 San Pedro, Wright. 

 * * Corolla lurid greenish-white or yellow, mostly darker-colored or brownish in the centre, with 



or without a brown-purple eye, small or middle-sized, 3 to 10 lines in diameter. 

 •i— Strictly annuals, glabrous or nearly so; the pubescence if any minute, and neither viscid nor 

 . stellate :' anthers violet. 



++ Corolla small, 3 to 6 lines broad: fruiting calyx at first acutely angled and inflated, closing 

 over, but at full maturity nearly replete with the greenish-yellow berry: stem and branches con- 

 spicuously angular: petioles long and slender. 



P. obscura, Michx. Branches widely diffuse : leaves broadly deltoid-ovate, mostly with 

 truncate or subcordate base, unequally dentate, abruptly acuminate, membranaceous (1^ to 

 3 inches long) : slender pedicels about half an inch long : corolla (3 or 4 lines broad) pale 

 yellow with a dark eye : calyx deeply 5-cleft into lanceolate-subulate lobes, in fruit ovate- 

 pyramidal and acuminate (over an inch long), very smooth, with 5 strong keeled angles 

 which are hardly obliterated at maturity, the 5 intermediate nerves much less distinct. —

 to 5 inches long) : slender pedicels an inch or more long :" corolla (3 to 6 lines broad) green- 

 ish-white or yellowish and with no distinct eye : calyx-lobes shorter than the tube,'trian- 

 gular : fruiting calyx at first ovate-pyramidal and 10-angled, the 5 principal angles sharply 

 keeled, at full maturity nearly replete and globose-ovate. — Dill. Elth. i. 13, t. 12. — Open 

 rich grounds, through #he Middle and Southern Atlantic States. (Widely diffused over 

 tropical regions.) 



Var. Linkiana, Gray, 1. c. Leaves with margin more laciniate-dentate; the irreg-

P. eequata, Jacq. f . Erect, much branched, a foot or two high, the younger stems and 

 branches a little hairy or pubescent : leaves ovate or oblong, repand or sinuate-toothed 

 (an inch or two long or rarely larger) : pedicels very short (a line or two long) : corolla 

 (3 to 5 lines broad) light yellow with a brownish eye: calyx-lobes short and broadly ovate- 

 triangular : fruiting calyx ovate-globose at maturity, about equally lO-nerved, an inch or 

 considerably less hi length. — Eclog. ii. t. 137 ; Nees, 1. c. ; Dunal, 1. c. P. Philadelphica,

 obliquely ovate or oblong, repand-angulate and sometimes few-toothed (2 to 4 inches long) : 

 corolla greenish or yellowish with a dark eye : calyx-lobes broadly ovate or triangular, not
