THE GENOTYPICAL RESPONSE OF THE PLANT 281 
sandy beach typical of the larger part of the coast strip of Halland and 
Scania becomes prevalent. At Nyhamn, about 10 kilometres to the 
south of Kullen, extensive fields of H. umbellatum are found. It 
grows here in the epilittoral dunes. Table 18 (fig. 41) gives the result 
of the cultivation of a series of individuals from this locality, which 
were brought home in 1920. When this series is compared with the 
material from Skelderviken, table 16, the nearest sand dune region 
to the north, the similarity in characters is found to be striking. This

is true not only of the width of the leaves but also of the characters 
of the leaf margin and of the inflorescence. 
It has already been stated that the dune form and the cliff form 
of this region differ widely from the form growing in the interior of 
Scania. It will be convenient at this stage to discuss this inland form 
more fully. The most important point of difference between the in- 
land form and the coast forms just discussed is the erect habit of 
growth in the former and the more or less plagiotropic growth of the 
latter. The stems of the inland type may form an angle with the 
vertical but only at the very base. By far the greater part of the 
stem stands erect or almost erect in most of the inland individuals, 
as is clearly seen in the photographs (figs. 44, 45). The average width
