520 The Inconstancy of Fasciated Races. 
and the atavists. This fact can be illustrated by statistical 
examination of the material, provided it can be made 
sufficiently large by cultivation. As an example of this 
I may again cite my race of Crepis biennis fasciata. 1 
In order to obtain a pure curve, I sowed the seeds 
of a single broadly fasciated individual of the third gene- 
ration of my race (1890) in March 1894. The plant 
had flowered together with two other fasciated individ- 
uals of the same ancestry, but this little group had been 
completely isolated. The seeds were sown in pans in the 
greenhouse and afterwards planted out at suitable dis- 
tances in the bed. Whilst still in the rosette stage many 
of them produced in the first year a comb-shaped heart. 
Others did not exhibit fasciation until the stem began to 
develop in the second year. Still others had not produced 
a single comb at the time when all their branches were 
fully developed. The external conditions had been as 
favorable as possible, so that I obtained a relatively high 
proportion of fasciated individuals. When I examined 
the plants in June of the second year, I obtained the fol- 
lowing result : 
Stems without fasciation 33 
with slight fasciation at the top . 9 
fasciated along their whole length 108 
Total 150 
The breadths of the stems of these latter 108 plants 
were distributed as follows : 
Cm. 2 3 4 5 6 7 8 9 10 11 12 13 14 19

The numbers are plotted in Fig. 118 in the form of 
a curve. In this curve indicates the group of 33 ata-
