340 DIDYNAMIA GYMNOSPETIMIA 



Obs. Thismo8t grateful aromatic, is apparently naturalised in ninny localities ; 



and is often cultivated about houses and gardens. The essential oil, and distilled 

 water, are well known for their stomachic properties ; and the Infusion of the 

 dried herb, administered cold, in small portions, is one of the best remedies for 

 nausea that I have ever tried.

Plant greyish green, pubescent. Root perennial. Stem 9 to 155 inches long, as- 

 cending, or decumbent, simple, or often with numerous long branches, angles 

 obtuse and retrorsely hirsute. Leaves 1 to 3 inches long, and half an inch to an 

 inch wide, somewhat oval-lanceolate, serrate, entire and tapering at base, resin- 

 ous-punctate, pilose, especially on the midrib, and nerves beneath ; petioles 1 

 third to 3 fourths of an inch long, slightly margined, pilose, hairs on the petioles 

 and leaves erect, or pointing forwards. Flowers in axillary pedunculate cymes, 

 appearing verticillate ; common peduncle 1 to 2 or 3 lines long: bracts lance-linear, 

 pilose-ciliate. Calyx hirsute, resinous-dotted ; segments hirsute-ciliate. Corolla 

 pale purple, or purplish white. Stamens 1 third to 1 half longer than the corolla. 

 Style longer than the stamens. 



Uab. Wet, low grounds; along Brandy wine : frequent. Fl. Aug. Fr. Sept— Oct. 



Obs. This species is not so pleasantly aromatic as the preceding,— its flavor 

 more resembling that of Iledeoma, or Pennyroyal. It is doubtful whether we have 

 any other native species in the U. Slates. The I\I. arvensis, noticed in my Cata- 

 logue, was evidently but the outcast of a garden,— and seems t<> have become ex- 

 tinct. Mr. Geo. W. Hall found a species near Rocky Hill, in E. Goshen, which 

 had strayed Into the meadows, and become almost naturalized. U is a stout erect 

 branching plant, entirely smooth, with broad ovate petiolate leaves, large terminal 

 capitate spikes, and bright purple flowers,— agreeing pretty well with the descrip- 

 lion of M. rubra, Stn.— or possibly it may be the M. citrala, Ehrh. Wiild. and 

 Bentham; M. odorata, Sm. in Rees' Cyclopcedia.
