LYCopus 395 



Var. PRAECOX (^Sole, 1. c. 31 (1798), as a species) ; under this I place 

 some intermediate forms or hybrids of M. sativa, which are found 

 occasionally, as by the Thames and Kennet. 



For a critical account of this extremely variable and difficult genus 

 the Essai de Classification et Descriptions des Menthes qii'on rencontre en Bel gique, 

 by the Abbe Strail, should be consulted. I am indebted to the vener- 

 able Abbe for kindly naming many of my specimens. 



M. arvensis, as an aggregate species, is found in all the bordering 

 counties.

&c. Rare. P. July-October. 

 First record. Pennyroyal, in the watery places near the confluence of 

 the Ocke and Lambourne, Spencer's Complete British Traveller, 1771. 

 There is some mistake here ; perhaps the Kennet, not the Ock, was 

 intended. M. Pulegium is definitely recorded in the Bot. Guide, 1805.
