Pkysalis. SOLAXACE^. 235 



purplish brown eye : pedicels {3 to 5 lines long) much shorter than the fruiting mostly 

 pubescent and viscid (inch to almost 2 inches long) calyx. — (Moris. Hist. iii. 527, sect. 13, 

 4, 3, fig. 24; Dill. Elth. t. 9, fig. 9.) P. obscura, var. viscido-pubescens, Michx. 1. c. P. hir- 

 stUa & P. pubescens, Dunal in DC. 1. c. P. viscosa ? Ell. Sk. 1. 279. P. pruinosa, L. (from 

 N. America 1), is most probably a form of tliis with long pedicels and yellowish anthers, 

 same as Dill. Elth. t. 9. — Low grounds, New York to Iowa, Florida, and westward from 

 Texas to the borders of California. (Trop. Amer., &c.) 



•w* -H- Perennial ; anthers mostly yellow. 



- P. Virginiana, Mill. A foot or so high from slender and deep creeping subterranean 

 shoots, at length spreading or decumbent, pubescent or hirsute-villous with (usually more 

 or less Tiscid) many-jointed hairs : leaves ovate, occasionally subcordate, either repandly 

 or saliently few-toothed or some nearly entire : corolla from three-fourths to a full inch in 

 diameter, dull sulphur-yellow with a brownish centre: calyx-lobes narrowly triangular: 

 pedicels half to an inch long, equalling or shorter than the fruiting calyx. — Diet. no. 4, & 

 Fig. PI. 138, t. 20(3, fig. 1; Gray, Proc. Am. Acad, x, 6.5 (by mistake "P. Virginka"). P. 

 heterophylla, Nees in Linn. vi. 403, excl. syn. Walt. " P. nutans, Walt. Car. 99 "! " ex Xees, 

 1. c. ; but no such name in Walter. P. heterophylla, nyctaginea, &, viscido-pubescens, Dunal, 1. c. 

 P. viscosa, Gray, JIan., not L. — Light or sandy soils, Upper Canada to Florida and Texas. 

 This early name of Miller, taken up for the present species in Proc. Am. Acad. 1. c, must 

 from the size of the flower belong to it, or to a broad-leaved and hairy form of P. lanceolata. 

 iliUer's remark that "the root does not creep in the ground," is most applicable to the 

 latter ; but the color as well as size of the corolla and the " pale yellow " fruit, also the 

 diffuse growth, best accord with tills common species. 



Var. ambigua, Gray, 1- ^- A coarse and very villous form with anthers violet ! — 



P. Pennsylmnica, Hook. Fl., at least in part. — Wisconsin [Lapham) to Saskatchewan, 

 Bourgeau, Dnimmond, &c. 



"P. hederaefolia. Gray, 1. c. A foot or less high, erect or at length diffuse from a 

 thick perennial stock or root, densely viscid-pubescent or on young parts more or less vil- 

 lous, not unpleasantly scented : leaves roundish-cordate or almost reniform, or sometimes 

 ovate, coarsely and obtusely angulate-toothed (three-fourths to an inch and a half in 

 diameter): corolla half an inch in diameter: anthers yellow: calyx-lobes triangular: 

 pedicels (2 to 4 lines long) shorter than the flower, much shorter than the fruiting calyx. — 

 P. Alkekengi'! var. digitaJifolia & P. mollis, in part, Torr. Bot. Mex. Bound. 1-53. — Rocky 

 hills, Xew ilexico to S. W. Texas, Arizona, and adjacent parts of Mexico. " Herbage des- 

 titute of the nauseous odor of the common viscid species, rather sweet-scented," Wright. 



Var. puberula, Gray, 1. c. Pubescence short and minutely glandular, less viscid: 

 stems inclined to be procumbent and leaves smaller. — Western borders of Texas, Wright. 

 P. PaJmeri. A span or two high from a thickish perennial stock, erect, viscid-pubescent 

 with short jointed hairs : leaves ovate or deltoid-ovate, or the lowest rotund (rarely even 

 subcordate), angulate-dentate with few obtuse teeth, the upper leaves acute (10 to 18 lines 

 long) : corolla light yellow with brownish centre, 7 or 8 lines in diameter: pedicels mostly 

 longer than the flower : fruit not seen. — Rock Spring in the Providence Mountains, S. E. 

 California, Palmer. Apparently allied to the preceding. 



-)— -1— -1— Perennials, not viscid, mostly low: anthers almost always yellow. 



-H* Very minutely cinereous-puberulent or glabrous throughout, no stellular pubescence whatever ; 

 corolla (yellowish) wholly destitute of a darker eye: leaves all cordate or broad and abrupt at 

 base, thiclii^h : pedicels long and filiform. 



P. GL.4BEA, Benth. (not Martins & Gal.), of Lower California, if found within the United 

 States will be known by being completely smooth, and the leaves ovate- or hastate-lanceolate. 

 P. crassif olia, Benth. Minutely puberulent, or the leaves at length nearly glabrous : 



stems a span to a foot long, branching from the base, sometimes soon procumbent : leaves 



ovate or rounded-subcordate, repand or entire : pedicels commonly an inch long : corolla 



ochroleucous, half inch in diameter : fruiting calyx an inch long, 5-angled. — Bot. Sulph. 



40 ; Gray, 1. c. & Bot. Calif, i. 541, the small-leaved form. — S. E. California and Western 



Arizona. (Lower Calif.) 

 Var. cardiophylla. A more upright form : leaves thinner and larger (6 to 15 lines 



long), sometimes with a few angulate and more prominent teeth. — P. cardiophylla, Torr. 



Bot. Mex. Bound. 153. — On or near the Rio Colorado, Fort Mohave, Fort Yuma, &c.
