Botanifts, both ancient and modern, feem to have been at a lofs with what genus of plants they mould clafs 

 this fmall inhabitant of our Corn-fields. At various times, and by various authors, it has been called a Sideritis, 

 a Lamium, a Marrubiajlrum, a Glechoma, a Stachys, and a Trixago. It appears neither to poffefs the ftriking 

 characters of any other genus, nor to afford fufficient diftiu&ion to form a genus by itfelf. As a fpecies, however, 

 there is no difficulty about it; its place of growth, the fmallnefs of its flowers, and form of its leaves, obvioufly 

 diftinguifh it from any other Englifh plant. 



It is not uncommon in the Corn-fields about the Oak of Honour and Coomb Woods, and elfewhere about London ; 

 it flowers in June, July, and Augufi,
