 pointed, the lower petioled, the lower floral as long as the flowers ; spike often 

 slender and more interrupted ; calyx-tube rather narrower and the teeth more 

 awl-shaped and spiny. Common in wet grounds. This passes into 



Var. grlfibra. (S. glabra, Riddell, suppl cat. Ohio pi. 1836.) More slen- 

 der, smooth and ylabrous throng/tout, or with few bristlv hairs ; leaves oblong- or 

 ovate-lanceolate, taper-pointed, more sharply toothed, mostly rounded or trun- 

 cate at the base, all petioled. W. New York (Sartwell) to Michigan and south- 

 westward. 



Var. COI'data. (S. cordata, Riddell, 1. c. S. Nuttallii, Shnttkiv.) Stem 

 beset with spreading or refiexed bristly hairs ; leaves hairy or smoothish, oblong, 

 keart-sliaped at the narrowed base, all more or less petioled ; calyx-teeth some- 

 times shorter. Common westward and southward. 



3. S. Iiyssopifolia, Michx. Smooth and glabrous, or nearly so ; stems 

 slender (1 high), the angles sometimes reflexed bristly ; leaves linear-oblong, 01 

 utrrou'ly linear, sessi/e, obscurely toothed towards the apex ; whorls 4 - G-flowered, 

 rather distant ; corolla (light purple) twice or thrice the length of the triangu- 

 lar-awl-shapcd spreading calyx-teeth, ty Wet sandy places, Massachusetts to 

 Michigan, and southward : rather rare. July.

Calyx top-shaped, 5-nerved, with 5 nearly equal teeth which are awl-shaped, 

 and when old rather spiny-pointed and spreading. Upper lip of the corolla 

 oblong and entire, somewhat arched ; the lower spreading, 3-lobed ; its mid- 

 dle lobe larger, broad and inversely heart-shaped, the lateral ones oblong. 

 Stamens 4, ascending under the upper lip : anthers approximate in pairs, the 

 valves naked. Nutlets truncate and sharply 3-anglcd. Upright herbs, with 

 cut-lobed leaves, and close whorls of flowers in their axils. (Name from Xeo>i>,
