Syme, t. 1022. Road-sides, c., Pennsylvania, Porter. Also a seeming hybrid between it 

 and J/. viridis. (Nat. from Eu.) 



Var. ALOPECUROfDES, Baker. Intermediate between the above and the next species : 

 leaves larger, more nearly sessile, broadly oval and obtuse, often subeordate, coarsely and 

 sharply serrate, more veiny, but not rugose: spikes usually thicker; bracts broader.

M. VIRIUIS, L. (SPEARMINT.) Glabrous or nearly so: leaves oblong-lanceolate or oblong, 

 sparsely and sharply serrate: bracts linear-lanceolate and subulate, conspicuous. Wet 

 ground, in cultivated districts. (Nat. from Eu.) 



-K- -w- Less capitate glomertdes in interrupted leafless spikes, or some in the axils of upper leaves: 

 flowers distinctly pedicellate: leaves distinctly petiolcd: steins less erect. 



M. PIPERI'TA, L. (PEPPERMINT.) Glabrous, or in one variety somewhat hairy, very pun- 

 gent-tasted : leaves ovate-oblong to oblong-lanceolate, acute, sharply serrate : spikes nar- 

 row, of numerous glomerulcs. Along brooks, escaped from cult. (Nat. from Eu.) 



M. AQUATICA, L. Soft-pubescent or glabrate, the stem with reriexcd hairs : leaves ovate, 

 roundish, or subeordate : spikes oblong and interrupted or capitate, thick : calyx and 

 usually the pedicels hairy.- -.17. cilratu, Ehrli. ; Engl. Bot. ed. Syme, t. 1029 (BEUGAMOT 

 MINT), a more glabrous and sweet-odorous variety. Wet places, New England to Penn- 

 sylvania, &c. ; rare. (Nat. from Eu.) 



Var. CRISPA, Benth. A glabrous or glabrate form, with lacerate-dcntate and crisped 

 leaves. M. crisjm, L. ; Engl. Bot. ed. Syme, t. 1028. Wet ditches, New Jersey, &c. (Nat. 

 from Eu.) 



H } Inflorescence axillary, in dense verticillastrate glomerulcs, on steins leafy to the top: leaves 

 more or less petiolcd, ovate or oblong-ovate, pubescent or glabrate. 



M. ARVEXSIS, L. Leaves obtusely serrate: calyx-teeth deltoid, acute or obtuse, about one- 

 tliird the length of the campanulate tube: otherwise same as forms of the next, which 

 passes into it. Engl. Bot. ed. Syme, t, 1038. New England, &c., at a few stations. (Nat. 

 from Eu.) 



M. SATIVA, L. Taller, generally more pubescent, the stem with reflexed soft hairs: leaves 

 sharply serrate: calyx-teeth triangular-subulate, half the length of the cylindraceous 

 tube, commonly hairy. Engl. Bot. ed. Syme, t. 1031, 1032. M. (jcnlilis, Smith in Linn. 

 Trans, v. 208, & Engl. Bot. t. 2118, a glabrate variety with only calyx-teeth hairy, and 

 these longer. Waste damp places, Mass, to Penn. ; uncommon. (Nat. from Eu.) 



* * Indigenous: inflorescence axillary, consisting of distant sessile verticillastrate glomerulea 

 in the axils of leaves, as in the preceding species, tliu uppermost axils flowerless. 



M. Canadensis, L. Stem often simple: leaves varying from oblong-ovate to oblong- 

 lanceolate, sharply serrate, acute, generally tapering into the petiole: calyx hairy; the 

 short teeth triangular-subulate. Spec. ii. 577. Wet places, through the Northern U. S. 

 from Atlantic to Pacific, and Canada and Saskatchewan to New Mexico and California. 

 Villous-hairy, with Pennyroyal odor: passes into 



Var. glabrata, Benth., with leaves and stem almost glabrous, the former sometimes 

 very short-petioled, and a sweeter scent, as of j\fonarda. M. loreulis, Michx. Fl. ii. 2. 

 Similar range.

 WORT, (y/t'xos', wolf, mn~s-, foot, wolf's-foot.) -- Perennials, of wet, or low ground 

 (northern temperate and Australian). Mint-like, but bitter and only slightly 

 aromatic ; with sharply toothed or lobed leaves, and small white or whitish flowers 

 in their axils, in sessile capitate-verticillastrate glomerules, the uppermost axils 

 flowerless. Fl. summer.-- Gray, Proc. Am. Acad. viii. 285.
