THE GENOTYPICAL RESPONSE OF THE PLANT 263 
It is thus seen that when a greater number of plants is taken, 
individuals with the characteristics of the inland form are also found 
to occur. It is, however, a point of much interest that these latter 
occur in a decided minority. The same has been found to be true 
of cliff series from Varberg in Halland and from Bohuslän. The Se- 
dum maximum vegetation of the rocky shores of Hallands Väderö, 
which would be expected to come close to that of Kullen, is made up 
of individuals the majority of which are flat-leaved and glaucus. It 
should be remembered, however, that the rich, herbiforous woods ma- 
king up the interior of that island and in close touch with the rocky 
shore include a multitude of Sedum maximum much resembling in 
certain characters the ordinary inland type, which, no doubt, incessantly 
recruits the shores with individuals of its own type. The leaves of the 
plants from the woods have a typical shade-leaf structure, as has 
already been pointed out by LunprGArpu (1919), while the plants from 
the rocky shores have sun-leaf structure. The shade-leaf structure of 
the woodland plants is only a modification, which had entirely dis- 
appeared in 1922 in all individuals brought home from the island in 
1919. Fig. 35 shows two plants, one prostrate, the other almost erect, 
both belonging to this woodland series. 
The folded leaf maximum typical of the exposed sea cliffs of the 
west coast has also been found on the east coast of Scania, viz. on the 
cliffs at Stenshuvud. The folded individuals, however, are here mixed 
with flat-leaved in about equal proportions. The folding, further, is 
not so pronounced in the Stenshuvud plants as in the west coast plants. 
Fig. 36 (to the left) shows a leaf-folded individual from Stenshuvud. 
The colour of the leaves of these plants is pure green, not anthocyanic 
except towards autumn. The Stenshuvud series is thus seen to be 
rather different from the west coast series, even if certain characteri- 
stics of the west coast cliff type may be traced in some of the individuals. 
The series cultivated and examined from further up the east coast, 
viz. from Oskarshamn and Västervik in Smaland and from the islands 
off Stockholm have only been found to comprise rather long-stemmed, 
flat-leaved individuals, the majority of which have been found to be 
glaucus. Some series, for instance those from Stockholm, show all 
kinds of branching habit. Fig. 37 illustrates 3 plants belonging to a 
series of 15 brought home in 1920 from Nämndö (an island off Stock- 
holm). The prostrate plant is the only one in the collection, the erect 
habit characterizes a few, while the ascending habit predominates. 
Inland maximum has been collected in several places in Scania.
