1. L. nepetoides, Bcnth. Smooth, or nearly so ; leaves ovate, somewhat 

 pointed, coarsely crenate-toothed (2' -4' long) ; calyx-teeth ovate, rather olitusc, little 

 shorter than the pale greenish-yellow corolla,. — Borders of woods, W. Vermont to 

 Wisconsin, and southward. — Stem stout, 4° - 6° high, sharply 4-angled. Spikes 

 2'- 6' long, crowded with the ovate pointed bracts. 



2. L. SCrophulariaefdlius, Benth. Stem (obtusely 4-anglcd) and lower 

 surface of the ovate or somewhat heart-shaped acute leaves more or less pubes- 

 cent ; calyx-teeth lanceolate, acute, shorter than the purplish corolla (spikes 4' - 1 5' long) : 

 otherwise like the last. — Same geographical range. 



3. L. anisatus, Benth. (Anise Hyssop.) Smooth, but the ovate acute 

 leaves glaucous-white underneath with minute down ; calyx-teeth lanceolate, acute. 

 — Plains, Wisconsin and northwestward. — Foliage with the scent of anise. 



20. NEPETA, L. Cat-Mint. 



Calyx tubular, often incurved, obliquely 5-toothed. Corolla dilated in the 

 throat, 2-lipped ; the upper lip erect, rather concave, notched or 2-eleft ; the 

 lower spreading, 3-cleft, the middle lobe largest, either 2-lobed or entire. Sta- 

 mens 4, ascending under the upper lip, the lower pair shorter. Anthers ap- 

 proximate in pairs; the cells divergent. — Perennial herbs. (The Latin name, 

 thought to be derived from Nepete, an Etrurian city.) 



§ 1. Cymose clusteis rather dense and many-flowered, forming interrupted spikes or 

 racemes: tipper floral leaves small and bract-like. 



1. N. CatAria, L. (Catnip.) Downy, erect, branched; leaves heart- 

 shaped, oblong, deeply crenate, whitish-downy underneath ; corolla whitish, 

 clotted with purple. — Near dwellings: a very common weed. July -Sept.

2. N. Glech6ma, Benth. (Ground Ivy. Gill.) Creeping and trail- 

 ing ; leaves petioled, round kidney-shaped, crenate, green both sides ; corolla 

 thrice the length of the calyx, light blue. (Glechoma hederacea, L.) — Damp 

 waste grounds near dwellings. May - Aug. — Anther-cells diverging at a right 

 angle, each pair approximate and forming a cross. (Adv. from Eu.) 



21. DRACOCEPHALUM, L. Dragon-Head. 



Calyx tubular, 13- 15-nerved, straight, 5-toothed; the upper tooth usually 

 much largest. Corolla 2-lipped ; the upper lip slightly arched and notched ; the 

 lower spreading, 3-cleft, with its middle lobe largest and 2-cleft or notched at the 

 end. Stamens 4, ascending under the upper lip ; the lower pair shorter. An- 

 thers approximate by pairs, the cells divergent. — Whorls many-flowered, mostly 

 spiked or capitate, and with awn-toothed or fringed leafy bracts. (Name from 

 8pa<(ov, a dragon, and Ke<pa\r], head, alluding to the form of the corolla in the 

 original species.)
