392 LAMIACEAE 



First record. M. piperita. Watery places, Dr. Noehden, Mavor's Agr. 

 Berks, 1809. (This record may possibly be correct, but there is 

 great probability of its referring to a form of M. aquatica. Mr. J. 

 Lousley, in Russell's Catalogue, says it occurs in some of the wet pas- 

 tures in the Vale, which is even less probable than the preceding 

 record. Pi-ecisely recorded by Mr. W. T. Dyer in 1867 as follows : — 

 2. Ock. Sub-spontaneous on Boar's Hill, Rep. of Land. Bot. Exch. Club. 

 1867, as the var. vulgaris, Syme, 1. c. Mr. Boswell found it in 

 the same place in i86i and 1866. Uffington, by a pond-side.

 M. hirsuta, Dr. Noehden, Mavor's Agr. Berks, 1809. 



M. aquatica is a variable species. One of our commonest forms, 

 which is found in all the districts, is the var, subglabra (Baker, sub 

 M. hirsuta). This is very common by the Thames, and when growing 

 in a rich marsh with other vegetation attains a height of five feet. 



Var. AFFiNis (Boreau, Fl. Centre Fr. ii. 509, as a species), M. inter- 

 media. Host, not of Nees, Beck, or Opiz. The Abbe Strail so named for 

 me a mint which grows by the reservoir at Didcot, see Rep. of Bot. 

 Exch. Club, 342, 1891, and which bears much resemblance to M. piperita, 

 var. vulgaris. 



Var. Ortmanniana (Opiz, Natural, xi. (1826) 437, as a species). This 

 form which is near to, but not so glabrous as, M. affinis, Bor., occurs at 

 South Hinksey. 



Var. pedunculata (Pers. Syn. ii. 119, as a species), Wirtg. Menth. 

 Rhen. ii. No. 29. I have found it near Abingdon. Cumnor, &c. 



M. aquatica occurs in all the bordering counties.
