THE GENOTYPICAL RESPONSE OF THE PLANT 235 
illustrates the individuals in a clone obtained the same year by divi- 
ding an inland meadow plant (transplanted 1919). The differences 
as to height and shape of leaves are plainly seen. The anatomical 
structure of the leaves of these clones is also different, as is seen in 
figs. 75c and d. The cross-sections are made from leaves taken from 
the cultures in 1922. There is a slight but distinct difference in thick- 
ness. The thickness of the inland clone has been found to vary 
between .250 u. and 300 «., while the Kullen clone varies between 285 
a. and 350 u. The loose tissues rich in intercellular spaces, which are 
typical of the inland leaf, contrast strongly with the compact tissues 
of the Kullen leaf. These differences in the anatomy of the leaf have 
been found to be very typical of other series from the coast (Varberg, 
Fig. 13. Leontodon autumnalis. The type of the coast (to the left) and 
the inland type. 
Bohuslän) and the inland. In places where meadows and pastures 
run down to the shore, there is a great confusion of different forms, 
as series from such localities show. Such series have been transplan- 
ted from Vellinge and Hallands Väderd on the west coast, and from 
Vastervik on the east coast. They apparently represent different com- 
binations between the coast type.and the inland type. 
Plants from the clones represented in fig. 13 have been crossed. 
The F;-generation is multiform with regard to hairiness and to the 
shape of the leaf. The further discussion of the segregation will be 
put off till the next generations have been raised. It should be said, 
however, that in the F,-generation already produced types of leaves 
have appeared which differ from both of the parents, for instance pin- 
nate types with extremely narrow lobes (identical with the f. corono- 
pifolius Lge. of the floristic handbooks).
