Antirrhinum Ma jus Striatum. 121 



or sulphur as in the corresponding self-colored varieties.^ 

 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 majus liitcum rubro-striatum of medium 

 height. 



The richness of types of marking in tliese striped 

 v^arieties is very great. The stripes may be sparse and 

 very fine so that the flowers appear at first glance to be 

 pure yellow or wdiite; 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 flow^er is entirely red whilst the other 

 half is striped, and so on.- 



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 majiis and obtained 

 26% unstriped individuals from A. m. album rubro- 

 striatum, and 19% from A. m. lutcum rubro-striatum. 

 In other cases a far higher degree of purity is usually 

 obtained, e. g., in A. m. lutcum 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 l)e 

 sought in the incomplete inheritance of the striped char- 



A. m. alburn rubro-striatum, A. m. suJpIiureuiii rubro-venosum, 

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