‘““NOMINA REJICIENDA”™ 9 
It must not be forgotten that the main object of the revision 
of the Rules, to the drawing up and discussion of which so many 
botanists devoted much time and trouble five years ago, was the 
insuring of uniformity; and it is on this account that this List 
as been so largely adopted. Proposals, however, suc ose 
suggeste anchen, implying as they do the entire ethene 
of the List and further alterations every five rahe seem to ) 
strike at the root of the principle of uniformity. Asa Serer of 
detail, if the List is to be completely revised in 1915, it can 
hardly be worth while to add to it now; and this seems in itself 
sufficient reason for opposing the adoption of the aparece addi-

We are aware that the question of Seg additions to the List

coming Congress should decide at an ‘ons stage in its proceed-

As rerk already pointed out, it affects the principle of 
uniform ity. Moreover, during the interval between successive 
Congresses, otk who follow the principle of priority laid down 
by the Rules will be uncertain how far the names which they 
adopt are likely to be permanent. The establishment of new 
combinations is not a mere matter of bibliography but often

Many workers who have followed the List, sometimes salah 
their personal inclination, will naturally resent additions which
