NEPETA 



leaves and yellowish purplish or hlue flowers verticillate- clustered 

 in dense or interrupted bracted terminal spikes. Calyx narrowly 

 campanulate, somewhat oblique, slightly bilabiate, 5-toothed. 

 Corolla strongly bilabiate, the tube as long as the calyx : upper 

 lip erect, 2-lobed, the lower one spreading, 3-lobed, its middle 

 lobe broader than the lateral ones and crenulate. Stamens all 

 antheriferous, the upper pair longest: anthers 2-celled, their cells 

 nearly parallel. Nutlets ovoid, smooth. 



A. urticifolia Kydberg. Lophanthux urticifoliuB Be.nth. Glabrous: 

 stems erect and simple, 2-4 feet high : leaves thin, triangular-ovate, obtuse 

 to acute at the apex, truncate to cordate at base, 1-3 inches long, coarsely 

 and irregularly dentate, glabrous both sides, on petioles an inch or less 

 long: spikes dense, 1-3 inches long, an inch or less thick, sessile: bracts 

 linear-lanceolate, entire, or some of the lower ones ovate and more or less 

 toothed: calyx narrow-campanulate, 4-5 lines long, its lanceolate acumin- 

 ate-subulate teeth subequal, nearly as long as the tube, white or tinged 

 with purple: corolla light violet or purplish to white, 6-7 lines long. In 

 wet places in the mountains, Oregon to California and the Rocky Mts. 



A. occidentalis Heller. Vleckia occidentalis Piper. Glabrous below, 

 puberulent above: stems strict, simple, 2-4 feet high : leaves triangular- 

 ovate, obtuse or sometimes acute at the apex, cordate at base coarsely 

 serrate-dentate, green and glabrous above, canescent beneath, 1-2 inches 

 long, on petioles 6-1 2 lines long : spikes thick and dense, 1-4 inches long an 

 inch or more thick: calyx puberulent, narrow-campanulate, 4-5 lines 

 long, its triangular-subulate very acute teeth not as long as the tube, tinged

 mountains of Washington. 



* 12 NEPETA L. Sp. 570. 



Erect herbs with dentate or incised leaves and rather small 

 flowers in verticillate clusters usually crowded in terminal spikes 

 or axillary and cymose. Calyx tubular, somewhat oblique at the 

 mouth, 15-nerved, usually incurved, o-toothed, scarcely bilabiate 

 but the upper teeth usually longer than the lower. Corolla-tube 

 enlarged above, the limb strongly bilabiate: upper lip erect, entire, 

 emarginate or 2-lobed: lower lip 3-lobed, the middle one larger 

 than the lateral ones. Stamens 4, all antheriferous, ascending 

 under the upper lip : anthers 2-celled, the cells divaricate. Nut- 

 lets compressed-ovoid, smooth. 



N. Cataria L. Sp. 570. (Catnip) Densely tomentulose-canescent pale 

 green perennial: stems stout, much branched, 2-3 feet high, the branches 

 straight, ascending: leaves ovate to oblong, acute at the apex, coarsely 

 crenate-dentate, mostly cordate at base, 1-3 inches long, greener above 

 than below, all petioled : flowers in dense verticillastrate spikes at the 

 ends of the branches and stems : bracts small, foliaceous : bractlets subulate: 

 calyx densely pubescent, its teeth subulate the upper about one-half the 

 length of the tube: corolla nearly white or pale purple, dark-dotted, pubes- 

 cent outside, 5-6 lines long, its tube a little longer than the calyx, the 

 broad middle lobe of the lower lip crenulate. In waste places, naturalized 

 from Europe.
