Generic character, Lamiiim, L. Annual or peren- 

 nial, more or less hairy herbs ; root-stock short ; stems 

 square, ascending or erect ; leaves petioled. Flowers 

 sub-sessile in axillary whorls ; bracteoles linear. Calyx 

 sub-campanulate, 5-fid, sub-2-lipped, teeth spread- 

 ing, triangular, with cuspidate apices. Corolla 

 bilabiate, ringent, upper lip galeate, lower lip 3- 

 lobed, mid-lobe broad or narrow, lateral lobes 

 smaller, tube straight or ascending ; faux dilated, at 

 the base of which is usually the oblique ring of hairs. 

 Stamens four, inner shortest, connivent under the 



longer petioled. Flowering stems erect, ten to 

 eighteen inches high, often sub-terete at the base, 

 and a little sulcate below the nodes : leaves narrower, 

 teeth more distant, and less hairy than those of the 

 prostrate stems, ovate narrowing into the leafy bracts 

 which are almost lanceolate, sub-acute. Flowers in 

 distant whorls, usually 10-flowered, or less by non- 

 development of the rudimentary buds ; bracteoles 

 linear subulate, as long as or shorter than the calyx. 

 Calyx Jsub-campanulate, faintly 10-ribbed, teeth tri- 

 angular cuspidate, superior one sub-erect. Two

Specific character, Lamium galeoidolon, Crantz. 

 A perennial hispid or sub-glabrous herb ; root-stock 

 very short and nodose. Barren stems prostrate, one 

 to two feet long ; leaves ovate cordate, coarsely and 

 irregularly, doubly crenate serrate, accuminate, some- 

 times cordate, petioles as long as or shorter than the 

 laminse, lowest leaves sometimes sub-orbicular and 



lateral divergent, two inferior reflexed. Corolla 

 yellow bilabiate, upper lip oblong galeate, finely 

 pubescent above, and ciliate at its edges : lower lip 

 spotted and streaked with yellow brown, 3-lobed, 

 lateral angular and reflexed, mid-lobe narrow elongate 

 ascending ; tube pink, as long as the calyx, faux 

 slightly dilated, and constricted J the corolla's entire 

 length from the base by the oblique ring of hairs. 

 Stamens four, anthers 2-celled, brown, glabrous ; 

 filaments villous below, 'adhesion obscure after the
