Another very closely allied species M. medium BR. SCH. is general in 

 Europe and ought to be found here ; it is synoicous and is nearest to 

 M. Seligcri, but 1 find the utmost difficulty in discriminating the various forms ; 

 Limpricht retains M. rugicum as a fourth species, and certainly the leaf-margin 

 differs widely from that of the type, the teeth when present corresponding 

 to those of M. Zeligeri, while the leaf-base and cells are those of M. cuspid-alum. 

 The variety datum is scarcely more than a large form, with which M. Seligeri 

 had been confused, and through it the marginal teeth gradually disappear 

 until it passes into rugicum.
