 A depauperate form (jierpusilla) has a filiform scape an inch high, from an annual root, 

 much exceeding the leaves, and 2-5-flowered : Florida, Chapman. 



Var. longifolia. A coarser plant : leaves oblong-spatulate, 3 to 5 inches long and 

 tapering into a margined petiole, often with some coarse salient teeth: scapes with the 

 spike 5 to 12 inches long : flowers rather larger. — P. purpurascens, Nutt. 1. c. P. occiden- 

 ialis, Decaisne in DC. 1. c. — Arkansas and Texas to S. Arizona. (Adjacent Mex.) 

 P. hirtella, HBK. Root perennial, thick : leaves oblong-ovate or oblong-spatulate, gla- 

 brate, rather fleshy, entire or sparsely denticulate, 5-7-nerved, 4-10 inches long, narrowed 

 into a short and broad base or a broad-margined petiole : scape and long dense spike a foot 

 or two high, stout, hirsute : flowers longer than in the preceding (3 lines long), with corolla- 

 lobes ovate, acute ; those of the fertile closed form with apex of slender style commonly 

 protruding and the anthers perhaps sterile. (Staminate and open-flowered form as in P. 

 Vin/inica or more fertile, but not yet seen from California). — Nov. Gen. & Spec. ii. 229,

 in a remarkably large form. (Mex., Cliili.) 



* * Leaves linear or filiform: flowers very small : stamens onl3'2: small and slender annuals, 

 minutely pubescent or nearly glabrous : the individuals having exserted stamens and style and 

 open corolla not rarely fully fruitful. 



-f— Spike short, thick, and dense, in fruit an inch long: mature capsule 2 lines long. 

 P. Bigelovii, Gray. Mostly glabrous and green : leaves \^ to 4 inches long, rather 

 fleshy, obtuse, entire, shorter than the scapes : mature capsule ovoid-oblong, half longer 

 than the calyx, 4-seeded: only form known fully fertile, with style conspicuously and 

 the two stamens slightly exserted from the open corolla. — Pacif. R. Rep. iv. 117, & Bot.

 capsule about a line long: leaves occasionally with a few denticulations or divergent lobes. 



P. pusilla Nutt. Somewhat cinereous-puberulent : leaves about an inch long and half

 and at length considerably surpassing the bract and calyx, 10-28-seeded : seeds oblong, 

 usually angled by mutual pressure, obscurely rugose-pitted. — Trans. Am. Phil. Soc. n. 

 ser. V. 177 (char, imperfect) ; Gray, Man. 1. c. ; Chapm. Fl. 278. P. CaroUniana, Pursh, Fl.

 P. jtEDiA, L., enumerated by Muhlenberg as of the United States, is not met with in this 



country. 



P. cucullAta, Lam., which is P. maxima, Jacq., another Old- World species, said b}'' Pursh 



to inhabit Canada and Maine, is not found. Pursh may have taken a large P. Rui/elii for it. 

 P. Ei.ONGATA, Pursh, Fl. ii. 729, of Bradbury's collection on the Missouri, is unknown ; 



probably a glabrate form of P. Patai/onica. 



P. GL.^BRA, Nutt. Gen. i. 100, on arid soil near Fort Mandan, on the Upper Missouri, is not 



identified ; perhaps a form of P. eriopoda, Torr., with loose spike.
