4. P. glatoers'iaita, L. Stems slender, erect (1-3 C high) ; leaves linear- 

 lanceolate 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 peduneled (pink or whitish) ; calyx-teeth 

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

 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 oblong, lanceolate, or 

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

 cleft., tlie teeth hiuar-ati'l-sliaped or setaceous. 



5. P. pilosa, L. Stems slender, nearly erect (1-U 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 aid-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 I' -2 f 

 long, l"-3" wide. 



Var. ? Wdlteri. Stems ascending (-H high), mostly simple; leaves, 

 broadly linear, lanceolate or ovate-ublong, abruptly acute or blunt (I'-l^' long, on 

 sterile shoots often ovate); cyme compact and sessile, leaf y-bracted ; calyx-teeth 

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

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

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

 pilosa, which is the P. aristata of Michaux. 



6. P. ivptaDS*, Michx. Runners creeping, bearing round ish-oboi-ate smooth- 

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

 obtuse leaves (^' long), clammy-pubescent; cyme close, few-flowered; calyx-teeth 

 awkshaped-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. divaricf&ta, L. Stems spreading or ascending from a decumbent 

 base (9' 18' high) ; leaves oblong-ovate or the lower oblong-lanceolate (1^' 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. !>Ifi<!a, Beck. Stems ascending, branched (5' -8' high) ; leaves I'n- 

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

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

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

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



# * * # Stems creeping and tufted in broad mats, the short floicerimj shoots ascend- 

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