POLEMONIACE^. (POLEMONIUM FAMILY.) 331 



4. P. glabcrrima, L. Stems slender, erect (l-3 high) ; leaves linear- 

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

 revolutc 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, Ai/dn.) 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 peduncled : calyx deeply 

 cleft, the teeth linear-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, Benih. in DC.) Borders of thickets and 

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

 long, l"- 3" wide. 



Var.? Walteii. Stems ascending (-l high), mostly simple; leave* m 

 broadly linear, lanceolate or ovate-oblong, abruptly acute or blunt (l'-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., 

 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. reptans, 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-flowere*d ; 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 (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 o' 

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



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

 ear, becoming nearly glabrous ('-!' long, l" 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 (J' long), equalling the tube, the 

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



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



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