4. P. glaberrima, L. Stemsslender.erect (l°-3°high); /cawesKnmr- 

 lanceolate or rarely oblong-Umceolate, very smooth (except the rough and sometimes 

 revolute margins), tapering gradually to a point (3' -4' long); cymes few- 

 flowered and loosely corymbed ; flowers pedunclcd (pink or whitish) ; calyx-teeth 

 sharp-pointed. (P. camea, Sims. P. revoluta, Aildn.) — Prairies and open 

 woods, Ohio and Wisconsin to Virginia and southward. July. 



* * # Stems ascending (or in No. 5 ojien erect) from a spreading or prostrate hose, 

 more or less clammy-pubescent, as well as the calyx and the oblong, lanceolate, or 

 linear leaves; flowers in terminal corymbed cymes, mostly peduncled: calyx deeply 

 deft, the teeth linear-awl-shaped or setaceous. 



5. P. pildsa, L. Stems slender, nearly erect (l°-lj° high), usually 

 hairy, as are the lanceolate or lance-linear leaves, which commonly taper to a sharp 

 point ; cymes at length open ; calyx-teeth slender, awl-shaped and awn-like, longer 

 than the tube ; lobes of the pink or rose-red corolla obovate, entire. (P. aristata, 

 Michx. P. aristata & pilosa in part, Benth. in DC.) — Borders of thickets and 

 prairies, New Jersey to Wisconsin and southward. May, June. — Leaves 1' - 2' 

 long, l^"-3" wide. 



Var. ? Wfllteri. Stems ascending (J°-l^° high), mostly simple; leaves 

 broadly linear, lanceolate or ovate-ohlong, abruptly acute or blunt (I'-lJ' long, on 

 sterile shoots often ovate) ; cyme compact and sessile, leafy-bracted ,• calyx -teeth 

 rather shorter and broader; corolla purple. (P. pilosa, Walt., Michx., Ell., 

 Benih. in part, not of L.) — BaiTens of Kentucky {Short), Virginia, and south- 

 ward. May. — Ordinarily this appears quite distinct from the Linnsean P. 

 pilosa, which is the P. aristata of Michaux. 



6. P. rcptans, Michx. Runners creeping, bearing raundish-obovate smooth- 

 ish and thickish leaves ; flowering stems (4' - 8' high) and their oblong or ovate 

 obtuse leaves {^' \ong), clammy-pubescent; cyme close, few-flowered; calyx-teeth 

 awl-shaped-linear, acutish, about the length of the tube ; lobes of the reddish-pur- 

 ple corolla round-obovate, entire. — Damp woods, Penn., Kentucky, and southward : 

 also cultivated. May, June. — Flowers showy: tube of the corolla 1' long; 

 limb 1' broad. 



7. P. divaricata, L. Stems spreading or ascending from a decumbent 

 base (9'- 18' high) ; leaves oblong-ooate or the lower oblong-lanceolate (I^' long), 

 acutish ; cyme corymbose-panicled, spreading, loosely-flowered ; peduncles 

 slender ; calyx-teeth slender awl-shaped, much longer than the tube ; lobes of the 

 pale lilac or bluish corolla obcordate or wedge-obovate and notched at the end, or often 

 entire (var. Laphamii, Wood), ^'-§' long, equalling or longer than the tube, 

 with rather wide sinuses between them. — Rocky damp woods, mountains of 

 Virginia to N. New York, Wisconsin, and northward. May. 



8. P. bifida, Beck. Stems ascending, branched (5' -8' high); leaves lin- 

 ear, becoming nearly glabrous (J' -1 J' long, 1 J" wide) ; flowers few, on slen- 

 der peduncles ; calyx-teeth awl-shaped, about the length of the tube; lobes oftlie 

 pale purple corolla 2-cleft to or below the middle (i' long), equalling the tube, the 

 divisions linear-oblong. — Prairies of Illinois, Mead (and Missomi). May. 



* * # # Steins cre^ing and tufted in broad mats, the sliort flovxring shoots ascend- 

 ing, glandular-pubescent ; the rigid narrow leaves crowded and fascicled.
