LABIATE. 



Stachys. 



or emarginate : lower lip mostly longer, spreading, 3-lobed ; the middle lobe largest, enlire 

 or emarginate. Stamens 4, ascending ; the lower ones longer : anthers approximated by 

 pairs. — Herbaceous or frutescent plants ; the whorls 2 - many-flowered, often in a terminal 

 spike. 



1. Stacpiys aspera, Michx. Rough Hedge-nettle. 



Stem retrorsely hispid ; leaves oblong-lanceolate, on short petioles, acute, often rounded at 

 the base, serrate, smoothish or with scattered rigid hairs above, and naked except on the veins 

 underneath ; whorls about 6-flowered ; teeth of the calyx divaricate and spine-like. — Michx. 

 fl. 2. p. 5 ; Pursh, fl. 2. p. 407 ; Bigel. fl. Bost. p. 236 ; Torr. compend. p. 234 ; Beck, 

 hot. p. 279 ; Benth. Lab. p. 543 ; Darlingt. fl. Cest. p. 359. S. hispida, Pursh, I. c. 



Perennial. Stem about 2 feet high, sparingly branched, rather slender ; the angles usually 

 very hispid with stiff hairs, which are spreading and partly reflexed ; the concave sides often 

 smooth. Leaves 2-5 inches long, thin, more or less hispidulous above with appressed hairs ; 

 the under surface smooth, except the few hairs that are sprinkled on the veins. Whorls rather 

 approximated, and forming interrupted terminal leafy spikes 6-8 inches long, each whorl 

 about 6- (but sometimes 8-) flowered. Calyx tubular-campanulate ; the teeth more than half 

 the length of the (often smoothish) tube, hispid-ciliate. Corolla pale violet-purple, more or 

 less pubescent externally, with a hairy ring in the tube. Achenia roundish-obovoid, brown, 

 nearly smooth. 



Wet thickets and borders of rivulets ; rather common. July - August. Nearly allied to 



S. palustris. 



2. Stachys palustris, Linn. Marsh Hedge-nettle. 



Herbaceous, erect ; stem pubescent, the angles with spreading or reversed hairs ; leaves 

 somewhat sessile, oblong- or ovate-lanceolate, serrate-crenate, rounded or cordate at the base, 

 rugose, hispid, or the lower ones smooth; whorls 6- 10-flowered, distinct, the uppermost 

 somewhat approximated ; calyx campanulate, hispid , the teeth lanceolate, acute and rather 

 spiny ; corolla twice as long as the calyx {Benth.). — Linn. sp. 2. p. 580 ; Engl. hot. t. 1675; 

 Benth. Lab. p. 543. S. hispida, Nutt. gen. 2. p. 30 ? S. sylvatica, Darlingt. fl. Cest. 

 p. 360. 



Perennial. Stem 2-3 feet high, branching, sometimes nearly smooth except at the joints. 

 Leaves 3-5 inches long and 1-2 inches wide, pubescent or smoothish, acute ; the petioles 

 3-6 lines long. Whorls numerous, mostly 6-flowered, forming a long terminal interrupted 

 spike. Calyx rather sparingly hispid, 10-nerved ; the teeth divaricate and spinescent at the 

 tip. Corolla purplish, more than twice as long as the calyx. 



Borders of woods and river banks ; in the western part of the State. July - August. — 

 This plant differs in several respects from my European specimens, and may be only a variety 

 of <S. aspera.
