generations which produced a greater or les> number of 
fasciations. The seeds of the finest fasciations of 1890, 
however, produced nothing but normal plants in 1891 
which did not exhibit the anomaly, even on a single 
lateral branch. They were weak plants and it looked 
as if the anomaly were lost once and for all; but seeds 
of these plants produced in the following year, 1892, 
fourteen plants, of which seven were fasciated. Six 
of them had 1 1 2 2 3 3 broadened stems, and 
one plant had as much as four large fasciations. More- 
over the lateral branches were so much affected by the 
anomaly that I found about one-third of them to be 
modified in this way. Since that time the anomalv has 
j * 
remained constant in this strain. In the third generation 
of my race of Amarantus speciosus (1891) the fascia- 
tions were also absent, but returned in the fourth and 
fifth generations in 30 and 50% of the individuals. In 
Helianthus annuus they were also absent from the third 
generation (1889), whilst the fourth contained about 
20% of fasciated individuals, and the anomaly has since 
remained constant. In the maize I observed fasciated 
ears in 3 cultivated race in the years 1888, 1889, 1892 
and 1893, but not in the generation of 1891, between 
these. From the seed of a very broad stem of Picris 
lueracioides (188?) I raised three generations under 
unfavorable conditions, and they did not produce a trace 
of the anomalv on manv hundreds of branches and stems. 
*> * 
It was not until the fourth generation that the anomaly 
reappeared, although only to a slight extent. Besides 
this strain. I have cultivated a race of biennial individuals, 
and these have presented fine instances of fasciations in 
greater or less abundance in every generation. 1
