Minden weed Rubi selecti exsiccati, No. 66) entirely confirm this 
idea. The e form is not infrequent both in North Yorkshire 
and the Bisa’ distr: ict. A. infestus appears to bear 2 pa much the

authors seem to be agreed. It is one of the commonest and best- _ 
navia to Fran tria. Focke and Genevier both accept our 
ordinary British plant, cry re as identical with what they 
by the same name. of them agree in rejecting our English 
**rudis’’ as identical with the German man and Focke 
place it as a su form of Radula under Lindley’s name, 
‘‘ echinatus.” It seems to me to differ ape ae the type Radula 
in the deeper dentation of the leaf. I do think R. Leightont 
Lees can stand where Nyman has placed mg under R. rudis. It
