Plant No. 107 and Plant No. 18 (Plates Nos. 11 and 12) illus¬ 
trate some other interesting variations. These two plants have made 
practically identical height growth. It so happened that both of these 
plants exhibited the same general color appearances and almost iden¬ 
tically the same type of leaf growth. The shape and general appear¬ 
ance of the leaf is so much alike that they can scarcely be distinguished. 
The chief differences to be observed in these two plants are that of 
tillering. Plant No. 107 is an exceedingly abundant stooler. The sto¬ 
lons put out from the roots are so abundant and vigorous that it is 
necessary to prume them back several times during the summer in 
order to keep this plant separated from the individual plants each side 
of it in the rows and in adjacent rows. Plant No. 18 on the other 
hand, puts out almost no stools. The plant at the time this picture 
was taken was three years old and yet the stool was practically of 
identical size as shown by measurements and counts, that it was dur¬ 
ing the latter part of its first season of growth. Our present expe-
