somewhat spiny, half the length of the purple corolla, diverging in fruit. — "Wet 

 banks of streams, &c., mostly northward. June -Aug. (Eu.) — To this, for 

 the present, we must refer all the following as varieties, different as some of them 

 are : — 



Var. aspcra. (S. aspcra, Michx.) Stem more commonly smooth on the 

 sides, the angles beset with stiff rcflexed bristles ; leaves hairy or smoothish, 

 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. — Tins passes into 



Var. glabra. (S. glabra, Riddell, suppl. cat. Ohio pi. 18.36.) More slen- 

 der, smooth and glabrous throughout, or with few bristly 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. cordata. (S. cordata, Riddell, I. c. S. NuttaUii, Skuttlew.) Stem 

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

 heart-shaped at the narrowed base, all more or less petioled ; calyx-teeth some- 

 times shorter. — Common westward and southward. 



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

 slender (1° high), the angles sometimes reflexed-bristly j leaves linear-oblong, m 



narrowly linear, sessile, obscurely toothed towards the apex ; whorls 4 - 6-llowcred, 

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

 lar-awl-shaped spreading calyx-teeth. \ — Wet sandy places, Massachusetts to 

 Michigan, and southward : rather rare. July. 



Betonica officinalis, the Wood Betony of Europe, — of a genus hard- 

 ly distinct from Stachys, — was found by C. J. Spraguc in a thicket at Newton, 

 Massachusetts.

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-lobcd leaves, and close whorls of flowers in their axils. (Name from \ea>v, 

 a lion, and ovpa, tail, i. e. Lion's-tuil.) 



1. Ij. Cardiaca, L. (Common Motherwort.) Tall; leaves long-peti- 

 olcd ; the lower rounded, palmately lobed ; the floral wedge-shaped at the base, 

 3-clcft, the lobes lanceolate; upper lip of the pale purple corolla bearded. 1| 

 — Waste places, around dwellings, &c. July- Sept. (Nat. from Eu.) 



2. I,. Marrubiastrum, L. Tall, with elongated branches; stem-leaves
