316 LABIATE. (MINT FAMILY.) 



teeth, the alternate ones shorter; corolla small, white. — Escaped from gardens 

 into waste places. (Nat. from Eu.) 



28. GALEOPSIS, L. Hemp-Nettle. 



Calyx tubular-bcll-shaped, about 5-nerved, with 5 somewhat equal and spiny- 

 tipped teeth. Corolla dilated at the throat ; the upper lip ovate, arched, entire ; 

 the lower 3-cleft, spreading; the lateral lobes ovate, the middle one inversely 

 heart-shaped ; palate with 2 teeth at the sinuses. Stamens 4, ascending under 

 the upper lip : anther-cells transversely 2-val.ved; the inner valve of each cell bristly- 

 fringed, the outer one larger and naked. — Annuals, with spreading branches, 

 and several - many-flowered whorls in the axils of floral leaves which are nearly 

 like the lower ones. (Name composed of yaKerj, a weasel, and o^/is, resem- 

 blance, from some likeness of the corolla to the head of a weasel.) 



1. G, Tetraiiit, L. (Common Hemp-Nettle.) Stem swollen below the 

 joints, bristly-hairy ; leaves ovate, coarsely serrate ; corolla purplish, or variegated, 

 about twice the length of the calyx; or, in var. gkandifl6ra, 3-4 times the 

 length of the calyx, often yellowish with a purple spot on the lower lip. — 

 Waste places, rather common. Aug. (Nat. from Eu.) 



2. G. Ladanum, L. (Red Hemp-Nettle.) Stem smooth or pubescent; 

 leaves oblong-lanceolate, more or less downy; corolla red or rose-color (the throat 

 often spotted with yellow), usually much exceeding the calyx. — Chelsea Beach, 

 near Boston, Bigelow. Aug. (Adv. from Eu.) 



29. STACHYS, L. Hedge-Nettle. 



Calyx tubular-bell-shaped, 5-10-nerved, equally 5-toothcd, or the upper teeth 

 united to form an upper lip. Corolla not dilated at the throat ; the upper lip 

 erect or rather spreading, often arched, entire or nearly so ; the lower usually 

 longer and spreading, 3-lobed, with the middle lobe largest and nearly entire. 

 Stamens 4, ascending under the upper lip (often rcflcxed on the throat after 

 flowering): anthers approximate in pairs. Nutlets obtuse, not truncate. — 

 Whorls 2 -many-flowered, approximate in a terminal raceme or spike (whence 

 the name, from ardxvs, a spike). 



* Root annual : stems decumbent, low. 



1. S. arvensis, L. (Woundwort.) Hairy; leaves petioled, ovate, ob 

 tusc, eremite, heart-shaped at the base ; axillary whorls 4 - 6-flowered, distant ; 

 corolla (purplish) scarcely longer than the soon declined unarmed calyx. — 

 Waste places, E. Massachusetts; scarce. (Adv. from Eu.) 



* * Root perennial : stem erect. 



2. S. palBfiStris, L. Stem 4-angled (2° -3° high), leafy, hirsute with 

 spreading or reflexed hairs, especially on the angles ; leaves sessile, or the lower 

 short-pctiolcd, oblong- or ovate-lanceolate, crenately serrate, rounded or heart- 

 shaped at the base, do amy or haiiy-pubescent, obtusish (2' -4' long), the upper 

 floral ones shorter than the nearly sessile calyx ; whorls 6 - lO-flowered, the up- 

 per crowded into an interrupted spike; calyx hispid, the lance -subulate teeth
