LABIATE. (mint FAMILY.) 345 



usually the pedicels hairy. The common form has the stems hxiry downwards. 



— Muddy shores, Nanticoke River, Delaware, W. M. Canby. — Var. glabrXta, 

 Benth., a nearly smooth form, differing from Peppermint in the rounder leaves 

 and spike of 2 or 3 rounded heads (M. citrkta, Ehrh.). — Litchfield, Connecti- 

 cut, Dr. T. F. Men. (Nat. from Eu.) 



« • * Inflorescence axiUari), the globular whorls or clusters all in the axils of the leaves, 

 the uppermost axils not Jiower-iearing ; leaves more or less petioled, toothed. { The 

 species apparently ran together.) 



5. M. SATivA, L. (Whoeled Mint.) Stem Am»y <foiTOi«i)-<fe ; leaves ovate ; 

 calyx oblong-cylindrical with very slender teeth. Intermediate between the last 

 and the next, apparently runs into both. — River-banks, Lancaster, Penn., Prof. 

 Porter. (Adv. from Eu.) 



6. M. ARvtNSis, L. (CoEN MiNT.) Lower and smaller-leaved than the 

 last; calyx bell-shaped, the teeth short and broader. — Moist fields : rare. (Adv. 

 from Eu. ) 



7. M. Canadensis, L. (WildMikt.) Zeones varying from ovate-oblong 

 to lanceolate, tapering to both ends ; calyx oblong-bell-shaped, the teeth rather 

 short ; hairs on the stem when present not conspicuously reflexed. The com- 

 moner form is more or less hairy, and has nearly the odor of Pennyroyal. — 

 Var. GLABEATA, Bcnth. (M. borealis, Michx.) is smoothish, "the scent pleas- 

 anter, more like that of Monarda." {Prof. Porter.) — Shady wet places, Kew 

 England to Kentucky and northward. 



5. L'STCOPUS, L. Water HoEEHOuiTD. 



Calyx bell-shaped, 4-5-toothed, naked in the throat. Corolla bell-shaped, 

 scarcely longer than the calyx, nearly equally 4-lobed. Stamens 2, distant; the 

 upper pair either sterile rudiments or wanting. Nutlets with thickened margins. 



— Perennial low herbs, resembling Mints, with sharply toothed or pinnatifid 

 leaves, the floral ones similar and much longer than the dense axillary whorls of 

 small mostly white flowers; in summer. (Name compounded of Xukos, a wolf, 

 and Trovs,foot, from some fancied likeness in the leaves.) 



1. L. Virginieus, L. (Bugle-weed.) Stem obtusely 4-angled (6'- 18' 

 high), producing long and slender runners from the base ; leaves oblong or ovate- 

 lanceolate, toothed, entire towards the base, short-petioled ; calyx-teeth 4, ovate, 

 bluntish and pointless. — Shady moist places: common, especially northward. — 

 Smooth, often purplish, with small capitate clusters of very small flowers. — The 

 depauperate, few-flowered form, often tuberifcrous at base (L. uniflorus, Michx., 

 and L. pumilus, VaM), Lake Superior and northward, 



2. L. EuropSeus, L. Stemsharply4-angled(l°-3°high); leavesovate- 

 oblong or oblong-lanceolate, sinuate-toothed or pinnatifid, usually more or less 

 petioled ; whorls many-flowered ; calyx-teeth 5, triangidar-lanceolate, tapering to a 

 rigid very sharp point ; nutlets (smooth or glandular-roughened at the top) equal- 

 ling or exceeding the calyx-tube. (Eu. ) — Includes several nominal species (the 

 sterile filaments variable) ; among them in our district is 



Var. sessilifdlius. Nearly smooth, producing slender leafy runners from 

 the decumbent base ; leaves oblong-ovate, closely sessile or almost clasping, re-
