82 DIDYNAMIA— GYMNOSPERMIA. Mentha. 



On the banks of the Medway, Kent. Rand. Between Rochester 

 and Chatham. Miller. 



Perennial. September? 



Herb hairy all over, exhaling, when rubbed, the sweet scent of 

 Frankincense Thyme. Stem erect, 2 feet high, apparently un- 

 branched, leafy, all its hairs closely reflexed, various in length. 

 Leaves on rather short stalks, spreading, 1 to 2 inches long, 

 ovate-lanceolate, narrower than in the foregoing, sharply and 

 unequally serrated, acute, as well as entire, at each end. Whorls 

 dense, sessile, many-flowered, axillary, accompanying every 

 pair of leaves, and concealing the footstalks. Bracteas linear- 

 lanceolate, or awl-shaped. Flower-stalks thickly covered with 

 hairs of various lengths, spreading horizontally, or now and then 

 slightly recurved. Cal. tubular, clothed in every part, but most 

 densely at the base, with ascending hairs. Cor. hairy at the 

 outside, as well as in the throat ; its colour, according to Buddie, 

 nearly red. Stam. shorter than the corolla. Stijle much longer. 



Very closely related to the last species. How far it is distinct can 

 be determined by the discovery, and sufficient examination, of 

 fresh specimens only.
