alterations as are admitted at these revisions should be shown 
therafter in catalogues for the next period with the superseded 
name as synonym.” 
Irurther resolutions provided as follows: Names of horticultural 
varieties should, as far as possible, consist of a single word, and 
at most only three words are permitted. Varietal names in use for 
a variety of cne kind or genus of plant should not be used again for 
another variety of the same genus even in connection with another 
species. The varietal name should follow the specific name with 
or without the abbreviation “ var.” preceding it. 
The varietal name should not be in Latin unless it designates 
some character of the plant (e.g., nanus, albus), or its place of ori- 
gin (kewensis). Latinized proper names for varieties is not per- 
mitted. Thus, Victoria regia Tricker is the approved form, not 
Victoria regia Trickeri; Dianthus deltoides var. Brilliant (not bril- 
liantissimus). 
The prefixes Mr., Mrs., Miss, and their equivalents shou 
avoided, and also the articles “A” and “ The,” except in lan- 
guages where they form an integral part of the substantives (e.¢., 
“Giant,” not “The Giant’; but Pelargonium peltatum La 
rance). Iéxisting names need not be altered to conform to the 
new rules, but they apply to all new names proposed.
