lliiic, by the fea, in a dry fandy place; Mr. Robfon. Wiih. On 

 the edge of an old moat at Shingham, Norfolk. Rev. Mr. Forby. 

 fi is common in gardens. 



Ciiu/es 2 — 3-pedales, erccli, pilofi feu villofi, pilis fubdcflexis. Fo/ia 

 feffilia, elliptico-fubrotunda, rugofa, fupra fubinlofa, fubtiis villofa, 

 acute crenata ; inferiora elliptico-oblonga; fuperiora minora, in- 

 cifo-ferrata. Spic^ paniculatas, obtullufculo;, hirfuta?, interrupts, 

 verticillis omnibus fere remotiufcuiis. Bruileoe lanceolata:, hir- 

 fiitx, floribus duplo longiores, faspius deflexa; ; inferiores ovatx. 

 Piii fcdkellorum defiexi. Calyx parvus, campanulatus, undique 

 hirtus, dcntibus lanceolatis, longitudine tubi. Corolla fere pra-ce- 

 dentis. Stamina exferta. Odor totius herbie acris et ingratus. 



This fpecies is readily diftinguifhed by its fmell from every variety 

 of y[.fylvefiris^ nor has it been obferved to alter in that or any other 

 refpeft, except the variegation of its leaves, which in the garden 

 variety are ftrikingly blotched and ftriped with white; fometimes 

 they afTume that colour entirely. It is always a much lei's hoary 

 plant than M.fyhefris', the leaves are conftantly more or lels ellip- 

 tical, and frequently almoft round. The more interrupted fpikes, 

 broad braftea;, fhorter teeth of the calyx, and long projcding {la- 

 mina, which laft appear to be invariable, ferve alio to diftinguifh 

 M. rotundifol'ia. Neverthelefs it is not eafy to give a fpecific charac- 

 ter which will always enable a ftudent to know it from the former 

 fpecies, without adverting to its very peculiar acrid and uiiagreeable 

 fmell ; accompanied by a degree of vifcidity when touched, iirft 

 pointed out to me by the Rev. Mr. Forby. 



Mr. Sole efleems this one of the mofl: valuable Mints for medi- 

 cal purpofes, and has found it very efficacious in many cafes of ner- 

 vous debility.
