316 LABIATJS. (MINT FAMILY.) 



teeth, the alternate ones shorter; corolla small, white. Es<apcd from gardens 

 into waste places. (Nut. from Eu.) 



28. GALEOPSIS, L. HEMP-NETTLE. 



Calyx tubular-bell-shaped, about 5-ncrvCvl, with 5 somewhat equal and spiny- 

 tipped teeth. Corolla diluted 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-valved; 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 yaXe^, a weasel, and o\Jas, resem- 

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



1. O. TETRAHIT, L. (COMMON HEMP-NETTLE.) Stem swollen Mow the 

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

 about twice the length of the calyx; or, in var. GUANDIFLORA, 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 oblony-lanccolate, more or less downy; corolla red or rose-color (the throat 

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

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



29. STACHYS, L. HEDGE-NETTLE. 



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

 united to form, an upper lip. Corolla not dilated at the throat; die 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 reflcxed on the throat after 

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

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

 tin.- name, from ara^vy, a spike). 



# Root annual: stems decumbent, low. 



1. S, ARVEXSIS, L. (WOUNDWORT.) Hairy; leaves petioled, ovate, ob 

 tuse, crenate, 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. pillustris, L. Stem 4-anglcd (2 -3 high), leafy, hirsute with 

 spread in-r or rcflexed hairs, especially on the angles ; leaves sessile, or the lower 

 r^liort-pctiolod, oblong- or ovate-lanceolate, crcnately serrate, rounded or heart- 

 phapcd at the base, dovny or hairy-pubescent, obtusish (2' -4' !ong), the upper 

 floral ones shorter than the nearly sessile calyx ; whorls 6- 10-llowered. the up- 

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