LABIATiE. 



Pycnanthemum. 



Dry rocky woods and hill-sides ; rather common, particularly in the southern part of the 

 State. August - September. This and most of the other species have a taste intermediate 

 to that of Pennyroyal and Spearmint. 



2. Pycnanthemum clinopodioides, T. cy G. Basil-leaved Mountain Mint. 



Cymose heads contracted ; teeth of the calyx somewhat equal, short, subulate, and with 

 the summit canescently hairy ; leaves oblong-lanceolate, acute at each end, slightly serrate, 

 smooth above , the under surface (and also the stem) softly villous-pubescent ; petioles short ; 

 bracts linear-subulate ; teeth of the calyx lanceolate, acuminate. — Gray, I. c. 



Stem li - 2 feet high, clothed with a soft loose pubescence, sparingly branched. Leaves 

 2-3 inches long and 3-8 lines wide, pale green but never hoary (except the floral ones in 

 a slight degree), remotely denticulate-serrate, dotted, smoothish above. Heads more than 

 half an inch in diameter. Teeth of the calyx with bristly hairs at the summit. Corolla white : 

 upper lip entire or slightly emarginate ; middle lobe of the lower lip longest. Stamens 

 moderately exserted. Ovary bearded. 



Dry rocky hill-sides. Kingsbridge on the Island of New-York. August - September. The 

 broader leaved forms of this species make an approach to the narrow-leaved varieties of P. 

 incanum, but are easily distinguished by the other characters enumerated above, particularly 

 the want of hoariness in the foliage, and the small size of the heads. 



** Calyx almost equally toothed ; the cymules rather loosely capitate, mostly terminal in a corymbose panicle ; bracts shorter 

 than the flowers. Leaves sessile, or on very short petioles- 



3. Pycnanthemum Torrei, Bentli. Torreys Pycnanthemum. 



Stem strict, pubescent ; leaves varying from linear-lanceolate to oblong-linear, smoothish, 

 acute, remotely denticulate, narrowed at the base into a short petiole ; cymose heads contracted, 

 depressed-hemispherical ; calyx with nearly equal lanceolate acuminate teeth, and the bracts 

 whitish pubescent. — Benth Lab. p. 329 ; Gray, I. c. P. Virginicum, Natt, gen. 2. p. 33? 



Stem about 2 feet high, slender, purplish, clothed with a short soft spreading pubescence, 

 moderately branching. Leaves 2-3 inches long and about one-third of an inch wide, thin, 

 pubescent-ciliolate on the margin and a little downy on the veins underneath, pale green on 

 both sides. Heads rather more than half an inch in diameter, rarely proliferous, formed of 

 densely aggregated cymules not truly capitate. Teeth of the calyx with several bristly hairs 

 at the summit. Corolla 2-lipped, white ; the upper lip emarginate ; middle lobe of the lower 

 lip longest. Stamens exserted. Ovary naked at the summit. 



Dry rocky hill-sides, near Kingsbridge on the Island of New-York. August - September. 

 Intermediate between the preceding and P. lanceolatum. From the former it differs in its 

 narrow leaves, as well as in the smaller and more compact heads ; from the latter, in the 

 broader and petiolate leaves, narrow loose bracts, the flowers in clustered cymules (not in 

 dense heads), the larger and more ringent corolla, and in the exserted stamens. It is a rare 

 species, and has hitherto been found only in the above mentioned locality and in two other 

 places in New-Jersey.
