276 DICOTYLEDONOUS PLANTS. 



the rest, is. very variable. I have specimens from Whitesborough, 

 ^f. Y. , in which the leaves as are much attenuated at base as in 

 Pursh's figure o M. kalmiana ; but this is not a constant cha- 

 racter, nor do I know of any by which that species can be dis- 

 tinguished. Ostcego Tea. 



.2. M. Jistulosa Linn. : stem obtuse-angled, nearly smooth, hollow ; 



leaves oblong-lanceolate, acuminate, coarsely serrate, thin and nearly 



smooth, on slightly pubescent petioles ; heads simple or proliferous ; 



outer bracts oblong, smooth ; calyx long, curved, bearded ; corol 



rough, pale. 



HAB. Rocky banks. N! Y. to Car. July, Aug. If .Stem 2 

 feet high, always simple. Leaves yellowish-green, petioled, 3*- 4 

 inches long and 1 broad, membranaceous, nearly smooth, coarse- 

 ly toothed, flowers pale yellow, in heads which are smaller 

 than in the preceding ; corol pubescent. When cultivated the 

 leaves are often smaller, subcordate, ovate, and more hairy than 

 in the native state. Abundant near Rochester, N. Y. 



.3. M. allophyUa Mich.: stem obtuse-angled, branched and hairy 

 above ; leaves oblong-lanceolate, remotely toothed, smooth above, 

 somewhat hairy beneath ; heads simple ; outer . bracts ovate, acute, 

 coloured* calyx short, densely bearded at the throat. M. longifolia 

 Lam. M. mollis Pursh not of Linn. M. oblongata Ait. Torr. 



HAB. Rocky woods. tf. Y. to Car. July. U.Sicm 3 4 

 feet high, much branched. Leatcs often rounded at base, and 

 with, a few large teetfi, varying in the degree of pubescence. 

 Flowers in heads, about the size of the preceding, pale blue. 

 The ha"bit is sufficiently characteristic of this species. 



4. M. clinopodia Linn. : stem obtuse-angled, smooth ; leaves ovate- 

 lanceolate, remotely serrate, tapering at base, nearly smooth ; heads 

 simple ; bracts broad-ovate, acute, entire, nearly smooth ; calyx short, 

 ciliate ; corol pubescent, slender; M. glabra Linn. ? 



HAB. Woods. Can. to Car. Pursh. July Sept. 'it. Stem 

 3 feet high, obtuse-angled and nearly smooth. Leaves ovate- 

 lanceolate, tapering at base into a petiole, with a few serratures 

 near the middle, punctate as in the preceding, whitish beneath, 

 (closely resembling those of Clinopodium incanum,) though ap- 

 parently quite smooth. Flowers pale purple. I -am not sure 

 that this is the plant described by Pursh under the above name, 

 but I believe it to be. the Linneean one. ' It it cultivated at Al- 

 bany, and in many respects much resembles the preceding, with 

 which it may be hereafter united.

5. M. punctaHa Linn. : nearly smooth ; stem obtuse-angled, branch- 

 ed, white-downy ; leaves lanceolate-oblong, remotely and obscurely 

 serrate, smooth ; ffowers whorled ; bracts lanceolate, coloured, longer 

 than the whorl. M. lutea Mich. 



HAB. Pine barrens. N. J. to Car. W. to Miss. Sept. U and 

 <J. Stem 23 feet high, branched. Flowers in whorls; calyx
