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

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



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

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



M. piperita, L. (Pepperiviint.) 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 glomerules. — Along brooks, escaped from cult. (Nat. from Eu.) 



M. aquAtica, L. Soft-pubescent or glabra te, the stem with reflexed hairs : leaves ovate, 

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

 usually the pedicels hairy. —M. citrala, Ehrh. ; Engl. Bot. ed. Syme, t. 1029 (Bergaihot 

 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-dentate and crisped 

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

 from Eu.) 



+— -f— Inflorescence axillary, in dense verticillastrate glomerules, on stems leafy to the fop : leaves 

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



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

 third 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 eylindr-aceous 

 tube, commonly hairy. — Engl. Bot. ed. Syme, t. 1031, 1032. M. gent'dis, 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 glomerules 

 in the axils of leaves, as in the preceding species, the 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 Monarda. — M. borealis, Michx. Fl. ii. 2. — 

 Similar range.

 (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.
