236 GOTE TURESSON 
A few words should be said in regard to the treatment by syste- 
matists of some of the forms of L. autumnalis. NEuMAN (1882—83), in 
our country, has discussed the various forms. The above coast type from 
Kullen, Arild and Varberg is apparently identical with the form descri- 
bed under the name f. salinus Aspegr. There is another similar form, 
which Neuman describes as f. robustior. It differs from salinus 
mainly in being shorter in stature and in having more succulent leaves. 
There seems to be little doubt that this form is merely a habitat modi- 
fication of the former. For it has been found that plants answering 
to the description of f. robustior at the time of collecting have become 
taller and less fleshy upon cultivation as early as the year after trans- 
plantation. It is equally true, however, that the characteristics of 
these cultivated plants, which now match the plants of the coast type 
described above, are genotypically founded and are not to be regarded 
as modifications of inland plants. 
In summarizing the results of the cultivations the following con- 
clusions as to the existence of different hereditary types of L. autum- 
nalis seem to be justified. 
a. The type of the interior of Scania. The type includes rather 
tall plants with pinnatifid and usually hairy leaves. The leaf is com- 
posed of very loose tissues rich in air spaces. 
b. The type of the coast, as obtained from Kullen, Arild, and 
Varberg. This is composed of plants lower in stature than the inland 
type. The leaves are coarsely dentated or almost entire, and always 
smooth. The leaf is composed of very compact tissues, poor in air 
spaces, and is somewhat thicker than the leaf of the inland type. The 
plants of this type flower about two weeks earlier than the inland type. 
The f. salinus Aspegr. of systematic handbooks seems to cover this 
coast type. 
It may safely be held that the number of types characteristic of 
L. autumnalis in nature is not exhausted by these two. In sandy 
places along the coast plants with depressed, pinnate leaves are found, 
which have been described as f. coronopifolius Lge. The cultivated 
material of this form is too young, however, to permit of any definite 
conclusions as to the nature and importance of the form. The same is 
true of cultivated material of the Alpine forms of the species. It may 
be said, however, that the compactness and slight succulence of the 
leaves, characteristic of the coast type, seem to be characteristics of the 
Alpine forms as well, and are even more pronounced here than in the 
coast type.
