-1 -I Corolla purple or rose-red (not scarlet-red), with tube equalling or longer tlian the calyx: 

 flowers sessile or subsessile, 



w- Not over half inch long: tube of the corolla not exceeding the tips of the calyx-teeth : spike 

 mostly much interrupted: steins erect from filiform and sometimes tuberiferous rootstocks. (At- 

 lantic species, one extending north-westward to tlie Pacilie.) 



== Leaves obscurely or not at all cordate, sessile or short petioled. 



S. hyssopifolia, Michx. Glabrous and smooth throughout, or sometimes a hirsute 

 ring at the nodes : stems slender, about a foot high : leaves linear, sometimes oblong-linear 

 (1 or 2 inches long, H to 3 lines wide), entire or merely denticulate, even the lowest nar- 

 rowed at base and sessile : spike rather short and slender; the clusters 2-6 flowered : calyx 

 2 or 3 lines long, occasionally with a few bristly long hairs ; teeth broadly subulate : 

 corolla glabrous. Fl. ii. 4; Benth. 1. c. ; Gray, Man. ed. 2, 317, ed. 5,358. S. palustris, 

 Walt. Car. 102, not L. Wet and sandy soil, coast of Mass, to Michigan and Florida. 



Var. ambigua. Stouter, 1 or 2 feet high, sometimes with scattered retrorse bristles 

 on the angles of the stem : leaves broader, 3 to G lines wide, serrulate. Georgia, LeC'unte. 

 Kentucky and Illinois, Short, Buckley, E. Hall, c. 



S. palustris, L. From densely soft-pubescent to roughish-hirsute, leafy : stem 1 to 3 

 feet high, hirsute or hispid: leaves from ovate- to oblong-lanceolate, crenate-serrate, mostly 

 acute or acuminate (U to 3 inches long), sessile or subsessile by a broad and abrupt or 

 obscurely subcordate base ; the lowest little petioled ; all sometimes almost velvety- 

 tomentose beneath: clusters of the spike mostly approximate, 0-10-rlowered : calyx pubes- 

 cent or hirsute; the teeth subulate, nearly the length of the tube: upper lip of corolla 

 distinctly pubescent. Spec. ii. 580; Fl. Dan. t. 1103; Engl. Bot. t. 1(375; Bcntli. 1. c. - 

 Wet ground, Newfoundland to the Pacific in Oregon, south to Pennsylvania, and in the 

 Rocky Mountain region to New Mexico, north to Mackenzie River. (Eu., N. Asia.) 



S. aspera, Michx. 1. c. Taller, 2 to 4 feet high, usually less leafy, sparsely hirsute or 

 hispidulous-pubescent to nearly glabrous : stem mostly retrorse-hispid on the angles : 

 leaves thinner, from oblong-ovate to oblong-lanceolate (1 to 4 inches long), acute or 

 acuminate, rather obtusely serrate, nearly all distinctly petioled and with truncate or 

 merely subcordate base: calyx glabrous or glabrate, or with some scattered bristles ; the 

 tube obscurely striate when dry: corolla glabrous throughout. Benth. I.e. S. arvensis, 

 Walt. Car. 1(52, not L. S. hispida, Pursh, Fl. ii. 407. S. palustris, var. aspera, Gray, 1. c.

Var. glabra. Even the angles of the stem smooth and naked or nearly so : leaves 

 more conspicuously petioled, acuminate, and serrate. S. aniuia, Walt. Car. 101, not L.

 to Illinois and southward. Filiform stolon-like rootstocks more or less tuberiferous. 



= = Most of the leaves distinctly petioled; lower all long-petioled and cordate: corolla glabrous 

 or nearly so throughout, barely 5 lines long. 



S. Floridana, Shuttlew. Barely a foot high, with filiform stolon-like rootstocks termi- 

 nated by a moniliform tuber (of 2 or 3 inches in length), nearly glabrous, or the slender 

 stem minutely hirsute, at least the angles: lower leaves cordate-oblong, very obtuse, cre- 

 nate-dentate (three-fourths to 3 inches long), slender-petioled ; floral small and with cune- 

 ate subsessile base, hardly surpassing or shorter than the rather remote clusters of the 

 short spike: calyx-teeth aristulate-subulate, little shorter than the oblong-carapanulate 

 tube. Benth. in DC. Prodr. xii. 478 ; Chapm. Fl. 327, but root not annual. E. Florida, 

 Rugel, Buckley, Canht/, Palmer, Curtiss. 



S. cordata, Riddell. Two or three feet high, rather weak, hirsute : leaves all ovate- or 

 oblong-cordate, acuminate, crenate (2 to 5 inches long), nearly all long-petioled ; the floral 

 mostly minute : spikes slender, of numerous and small few-flowered clusters : calyx (only
