4. P. glaberrillta, L. Stems slender, erect (1-3 C high) ; leaves linear* 

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

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

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

 sharp-pointed. (P. carnea, Sims. P. revoluta, Aikin.) Prairies and rpen 

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



* * * Stems ascending (or in No. 5 often erect] from a spreading or prostrate base, 

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

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

 cleft, the teeth li near-awl-shaped or setaceous. 



5. P. pilosa, L. Stems slender, nearly erect (l-l 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 D C.) Borders of thickets and 

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

 long, l"-3" wide. 



Var. 1 ? Walteii. Stems ascending (-l high), mostly simple ; leaves, 

 broadly linear, lanceolate or ovate-oblong, abruptly acute or blunt (I'-l^' 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. t 

 Benth. in part, not of L.} Barrens of Kentucky (Short), Virginia, and south- 

 ward. May. Ordinarily this appears quite distinct from the Linnaean P. 

 pilosa, which is the P. aristata of Michaux. 



6. P. rf>tailS, Michx. Runners creeping, bearing roundish-obovate smooth* 

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

 obtuse leaves (^' long), 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-ovate or the lower oblong-lanceolate (H' 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. l>ifida, Beck. Stems ascending, branched (5' -8' high) ; leaves lin- 

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

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

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

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