 those of the branches often alternate : flowers scattered or somewhat corymbose : corolla 

 rose, " red " or " white," with tube somewhat exceeding the calyx ; its ample and broadly 

 cuneate-obovate or roundish lobes entire or nearly so (about half inch long) : ovules 2 or 

 often 3 in each cell. — PI. Gamb. 153; Gray, Proc. 1. c. 256. P. triovulaia, Thurber in Bot.

 less branched and more erect, the leaves narrower and all opposite. — New Mexico, es- 

 pecially on the Rio Grande, and adjacent borders of Colorado and Texas. 



§ 4. Annuals, all Texan, more or less pubescent with viscous or glandular 

 many-jointed hairs : leaves linear or oblong, most of the upper ones alternate : 

 calyx at length splitting almost to the base, the linear or subulate-lanceolate lobes 

 setaceous-tipped : style shorter or not longer than the stigmas : ovules in each 

 cell 1 to 5 : seeds with somewhat wing-like angles. 



P. Drummondii, Hook. Loosely branching, villous and glandular : leaves mostly 

 oblong or lanceolate, mucronate-pointed ; the ujjper commonly half-clasping by a broader 

 somewhat cordate base : flowers mostly in crowded cymose clusters : calyx-lobes lanceolate- 

 subulate, soon recurved : corolla red, varying to rose, purple, or white ; the lobes broadly 

 obovate, entire or nearly so (about half inch long) ; the tube usually pubescent : ovules 

 solitary in tlie colls. — Bot. Mag. t. 3441 ; Bot. Reg. t. 1949 ; Br. Fl. Card. ser. 2, t. 316. —

Var. villosissima, Gray. A very villous and viscous form, with more scattered 

 flowers of large size, and barely spreading calyx-lobes ; lobes of the pale corolla half inch 

 long- and broad. — Proc. Am. Acad. 1. c. 257. — S. Texas on the Nueces, Wright. 



Var. tenuis, Gray, 1. c. A small and slender form, mucli less pubescent ; with 

 mostly linear or almost glabrous leaves (about an inch long), rather narrower instead of 

 dilated at the base, and an open cyme of small flowers : lobes of the pink or purple corolla 

 only 2 to 4 lines long. — Common in Eastern Texas, Dnimmond, Lindheimer, Wright. Seem- 

 ingly very distinct. 



P. Roemeriana, Scheele. Loosely branched from the base, a span or more liigh^ 

 sparsely hirsute or glabrate (except the calyx-tube) : leaves lanceolate, or the oblong or 

 spatulate lower ones often glabrous except the margins : flowers solitary or sparse : calyx- 

 lobes linear, merely spreading : corolla pink or rose-colored ; the glabrous tube not exceed- 

 ing the calyx, about half inch long, shorter than the ample roundish-obovate entire 

 lobes : oviiles in each cell 4 or 5 ! — Linnaea, xxi. 752. P. macrantha, Buckley, in Proc. Acad.
