Antirrhinum Ma jus Striatum. 121 
or sulphur as in the corresponding self-colored varieties. 1 
It must further be mentioned that each of these types 
may exist in a tall, medium or dwarf form. In the ex- 
periment to be described the form I have used was 
Antirrhinum majns lutcum rubro-striatum of medium 
height. 
The richness of types of marking in these striped 
varieties is very great. The stripes may be sparse and 
very fine so that the flowers appear at first glance to be 
pure yellow or white; or the stripes may be bold and 
broad and very numerous in such a way that the yellow 
(or the white) appears in about equal parts with the red. 
Often half of a flower is entirely red whilst the other 
half is striped, and so on. 2 
If we buy seeds of the striped sorts and sow them, 
the crop raised is considerably less true than is usual in 
sowings of bought seeds. In 1899 I sowed samples of 
different varieties of Antirrhinum ma jus and obtained 
26% unstriped individuals from A. in. album rubro- 
striatnm, and \9% from A. m. tut cum rubro-striatum. 
In other cases a far higher degree of purity is usually 
obtained, e. g., in A. m. hit cum I found only 2% im- 
purities. 
The admixtures in the striped varieties were in the 
vast majority of cases uniform reds and therefore closely 
allied to them. Other deviations were not more numer- 
ous in the striped forms than in any other variety. The 
reason for the abundance of the red flowered individuals 
has been disclosed by subsequent culture ; it is to be 
sought in the incomplete inheritance of the striped char-

A. m. pumilum roscum rubro-striatum, etc.
