LABIATE. (mint FAMILY.) 421 



rowed at the base ; the middle lobe of the spreading lower lip broad, notched 

 at the apex, contracted as if stalked at the base, the lateral ones small, at the 

 margin of the throat. Stamens 4, ascending under the up]>er lip ; anthers ap- 

 proximate in pairs, 2-celled, the cells divergent. Nutlets truncate. — Decum- 

 bent herbs, the luwest leaves small and long-petioled, the middle heart-shaped 

 and doubly tootlied, the tioral subtending the whorled hower-cluster ; sj^ring to 

 autunm. (Name from Aai/ios, throat, in allusion to the ringent corolla.) 



* A7inuals or biennials, loic ; flowers small, purple, in few whorls or heads. 



L. AMPLEXiCAtJLE, L. Leaves rounded, deeply crenate-toothed or cut, the 

 i(j)/)er ones clasping; corolla elongated, upper lip bearded, the lower spotted 

 lateral lobes truncate. — Rather common. (Nat. from Eu.) 



L. PURPtjREUM, L. Leaves roundish or oblong, heart-shaped, crenate- 

 toothed, all petioled. — N. Eug. and Peun. (Xat. from Eu.) 



* * Perennial, taller ; flowers larger, in several axillary whorl's. 



L. Album, L. Hairy ; leaves ovate, heart-shaped, petioled ; calyx-teeth 

 very slender, spreading ; corolla white, the tube curved upward, obliquely con- 

 tracted near the base, where there is a ring of hairs inside ; lateral lobes of lower 

 lip bearing a long slender tooth. — E. New Eng. (Nat. from Eu.) 



L. macl'lAtum, L. Like the last, but leaves more frequently marked witli 

 a white spot on the upper face, and flowers purplish, with tlie ring of hairs 

 transverse instead of oblique. — Sparingly escaped. (Adv. from Eu.)

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

 tipped teeth. Corolla dilated at the throat ; 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 yaXerj, a weasel, and oi{/ts, re- 

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



G. TetrXhit, L. (Common Hemp-Nettle.) Stem swollen below the joints, 

 bristly-hairi/ ; leaves ovate, coarsely serrate; corolla purplish or variegated, 

 about twice the length of the calyx; or, in var. graxdifl6ra, 3-4 times the

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

Stamens 4, ascending under the upper lip (often reflexed 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). Flowers purple or rose-red, in summer.
