LABIATE. (MINT FAMILY.) 317 



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. aspera. (S. aspera, Michx.) Stem more commonly smooth on tho 

 sides, the angles beset with stiff reflexed 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. This passes into 



Var. glabra. (S. glabra, Riddell, suppl. cat. Ohio pi. 1836.) 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 (Sartwdl) to Michigan and south- 

 westward. 



Var. cordata. (S. cordata, Riddell, I. c. S. Nuttallii, Shuttlew.) Stem 

 beset with spreading or reflexed 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. hyssopifdlia, Michx. Smooth and glabrous, or nearly so ; stems 

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

 Inarrowty linear, sessile, obscurely toothed towards the apex ; whorls 4 - 6-flowered, 

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

 lar-awl-shaped spreading calyx-teeth. 1J. Wet sandy places, Massachusetts to 

 Michigan, and southward : rather raw. July. 



BBT6NICA OFFICINALIS, the WOOD BETONY of Europe, of a genus hard- 

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

 Massachusetts. 



3O. IiEONtJRUS, L. MOTHERWORT. 



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-angled. Upright herbs, with 

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

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



1. Li. CARD*ACA, L. (COMMON MOTHERWORT.) Tall; leaves long-peti- 

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

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

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



2. It. MARRUBIASTRUM, L. Tall, with elongated branches; stem-leaves 

 oblong-ovate, coarsely toothed ; corolla (whitish) shorter than the calyx-teeth; 

 the tube naked within ; lower 1 lip rather erect. (2) Road-sides, Pennsylvania : 

 rare. (Adv. from Eu.)
