specific names which he adopts for the plants transferred are not 
usually ag ped even though he has not preserved the old specific 
names in the new genus. In the present instance Moench’s name 
is not taken up, ean he neither founded the genus nor revived 
the name of Succisa, nor did eh us ue it in the now current sense in

therefore be the name of the British plant. Mr. Williams is to be 
congratulated on the well-sustained quality of his work. Great 
care has been taken in the use of words expressing colour.
