Hcspcris Matronalis. 14v3 



tending over seven years, in their relation to other known 

 facts we find that we can distinguish the following races : 



1. Hcspcris matronalis alba, the constant commercial 

 variety. 



2a. A whitisli, pale lilac, seldom or never striped 

 sort ([F1-W3), which can reproduce the violet color by 

 sectorial, bud- and seed-variation ; violet seed-variation 

 about 2% ; lilac offspring about 6%. 



2b. A lilac, often striped or spotted, race which gives 

 rise to an inconstant but mostly considerable number of 

 whitish and violet offspring. Its color merges contin- 

 uously into that of No. 2a, but is sharply separated from 

 No. 3. 



3. A violet variety wdiich has arisen from 2a and 2b 

 and is presumably inconstant, on the analogy of Antirrhi- 

 uiini iiiajus. 



4. Hcspcris matronalis, the original, constant, violet 

 species. 



The analogy with the corresponding races of An- 

 tirrhinum inajus seems to me to be obvious and can be 

 ex])ressed as follows : 



1. The systematic variety which is perfectly con- 

 stant {H. in. alba, A. niaj. lutcnm). 



2. The eversporting variety with lilac or striped 

 flowers (H. m. lilacina, A. maj. lutcnm striatum^. It 

 can be split by selection in a plus and in a minus direction ; 

 into a pale lilac, or finely striped race on the one hand, 

 and on the other into the dark lilac and frequently striped 

 dame's violet and the broadly striped snapdragon. 



3. The self-colored but inconstantatavistictvpe which 

 has the color but not the constancy of the original s])ccies. 



4. The original violet, or red, perfectly constant spe- 

 cies (Hcspcris matronalis, Antirrhinum ma jus).
