SNOWDROP-TREE 
tion for the Advancement of Science decided, if possible, to 
bring order out of the perplexing situation. Two rules were 
established. One—that every plant should hereafter be 
known by the name under which it was first published to the 
world, unless that had already been given to another plant; 
and the other—that no later name should stand whether 
the first did or did not. Now comes the result. The trop- 
ical Halesia was found to be no genus at all but only a spe- 
cies which was soon referred to its proper place. There 
then remained but one AHa/esta. But here the second rule 
came in, and so our pretty Silverbells lost their generic name, 
It was then suggested that they should be named JAZohroden- 
dron in honor of Dr. Charles Mohr, an eminent botanist of 
Alabama. The suggestion was accepted and so Stephen 
Hales was deposed and Dr. Mohr reigns in his stead.
