striped plants exhibit a stronger tendency to produce 
bud-variations than the finely striped ones. 
Sectorial variation is very diverse in the manner of 
its manifestation. I found it as a rule on the main stem, 
but also on the branches. If the inflorescence is looked 
at from above, i. e., in projection, one sector is red whilst 
the rest is white. This red sector often consists of a 
narrow red stripe only, or of one-half or three-quarters 
of the whole. As a rule the abnormality extends from 
the base to the top of the spike ; but it may also be con- 
fined to part of it, especially when it consists of a narrow 
line only. A single red flower on an otherwise striped 
spike is by no means a rare occurrence. On the borders 
of the two sectors the flowers are often striped on one 
side and red on the other. As in the case of bud-varia- 
tions it is the coarsely striped individuals which are most 
prone to the sectorial dissociation of color. 
The red color occurs not only on the corolla but also 
on the stamens. In finely striped flowers the stamens 
are, as a rule, yellow ; in flowers with broad stripes they 
are striped or red. The individual stamens in the same 
flower are usually dissimilar in respect to this character; 
yet it is difficult to find a strong contrast within a single 
flower, e. g., a single stamen which is almost red, and 
another nearly yellow. I have spent much trouble in 
the attempt to find such flowers, especially in those that 
had one longitudinal half almost or entirely without 
stripes. But I did not discover any definite relation 
between the striping on the stamens and that on the 
corresponding parts of the corolla. 
As a matter of fact pure yellow flowers never occur in 
this race. To a superficial observer it may seem as if 
they were not rare and even that the red stripes may
