The Fs-families 1048, 1049 and 1050 are descendants from plants 
with AaBbGGLl as genotypic formula; the Families 1045 and 
1057 from A a B b G G L L:-individuals, 1046 from an AABbGGLL- 
plant, while 1053 and 1054 have had an A A BbGG Ll-individual 
as ancestor. 
12d. Cross oF BRUINE X WITTE. 
A third phaenotype was also found in a culture of Bruine as 
spontaneous hybrid from a white seeded pollenparent: a plant 
with yellow-brown-marbled seeds, identical with the phaenotype of 
group II in the previous crosses. In the same manner as the Fo, 
raised from this F ,-plant, some other F3-posterities, grown from 
the yellow-brown-marbled Fo-individuals mentioned under 12c, 
segregated into 6 yellow-brownmarbled : 6 yellow-brown selfcoloured 
:4 white. For the numbers of segregation were in these cases: 
8:5:3; 12:14:9; 21:19:14; 9:11:5 and 26:22: 17, or as totals 
76:73:48, being expected the proportions of 737/g: 737/g: 491/,. 
This spontaneous hybrid, as also the Fo-plants in the foregoing 
cross had the genotypic formula of AaBbGG and segregated 
into 6 ABbG:6 ABB (or bb) G and 4 a-plants. 
13. Cross oF CITROEN X WITTE? 
As last cross among Phaseolus vulgaris a spontaneous hybrid 
may be mentioned, found in a culture of the Citroen-race, that gave 
a segregation somewhat parallel with those of the hybrids, treated 
under 12b. The red-brown and yellow-brown types are missing here 
entirely; in other directions the hybrid however shows a more 
detailed segregation. The F -plant had greyish black-marbled seeds 
with a greyish-white groundcolour (pl. I fig. 9) and segregated in 
F, into eight phaenotypical groups. I was identical with the F;-type;
