 fornian specimens, the corolla is an inch or more in diameter. 



Var. Sabini, Gray, 1. c. Differs only in the lobes of the corolla being entire or 

 barely retuse (obovate with a narrowed cuneate base). P. Sabini, Dougl. in Hook. 1. c. ; 

 Benth. 1. c. P. speciosa, var. elutior, Hook. Fl. ii. 72. Spokan River, Dour/las, Lijall. 



Var. \VoodllOUSei, Gray, 1. c. Small form, a span high, with linear leaves not 

 broadened at base, and a much smaller corolla ; its cuneate-obcordate lobes only 4 lines 

 long. P. nana, Torr. in Sitgreaves Rep., not Nutt. Arizona, near Williams Mountain, 

 Dr. WoodJiouse. 



P. nana, Nutt. Glandular and roughish-pubescent, loosely and copiously branching 

 from a somewhat ligneous base, a span or more high: leaves linear (an inch or two long), 

 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-obovatc 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. triovnlata, fhurber in Bot. 

 Mex. Bound. 145. Var. glabdla, Gray, 1. c., is merely a less pubescent or glabrate form, 

 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. Drummoildii, Hook. Loosely branching, villous and glandular: leaves mostly 

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

 somewhat cordate base : flowers 7iiostly in crowded eymose 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 the cells. Bot. Mag. t. 3441 ; Bot. Reg. t. 1949 ; Br. Fl. Gard. ser. 2, t. 316. 

 Texas, especially in the eastern districts, and everywhere familiar in gardens. 



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 

 lonar and broad. Proc. Am. Acad. 1. c. 257. S. Texas on the Nueces, Wr'njht. 



Var. tsnuis, Gray, 1. c. A small and slender form, much 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, Dru.mm.ond, Lindheimer, Wright. Seem- 

 ingly very distinct. 



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

 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 : ovules in each cell 4 or 5 ! Linna\a, xxi. 752. P. macrnntha, Buckley, in Proc. Acad. 

 Philad. 1862, 5. Texas, near San Antonio, &c., on high prairies. Commonly with most of 

 the leaves alternate !

 flowers worthy of cultivation. Lower leaves usually opposite. Nutt. Gen. i. 

 126 ; Gray, Proc. Am. Acad. viii. 258. 



1. EUCOLLOMIA, Gray. Ovules solitary or in the last species 2 or 3 in each 

 cell : corolla salverform or almost so : annuals, more or less viscid-pubescent or 

 glandular. - - Collomia, Benth. in DC. Prodr.. with one Navarretia. ( C. gracilis
