THE GENOTYPICAL RESPONSE OF THE PLANT 265 
d. The type of the cultivated regions of the southern interior o} 
Scania. This is taller than any of the preceding types, has an erect 
habit of growth and flat, green (rarely indistinctly glaucus) leaves. 
The type may be a garden escape, although evidence in that direction 
has not been forthcoming. 
6. MATERIAL AND CULTURES OF INLAND AND COAST 
FORMS OF ARMERIA VULGARIS WILLD. 
Sets of turfs of this variable species have been collected in the 
years 1918—1922 from various places along the coast and from the 
interior and grown in cultures. The sets obtained from the west coast, 
viz. from Marstrand, Bohuslän, 1920; Varberg, Halland, 1920; Hallands 
Väderö, Scania, 1919 and Vellinge, Scania, 1918 show a remarkable va- 
riation as to the scape (hairy and smooth), length and shape of the 
bracts, hairiness of the calyx etc. Plants transplanted from localities 
on the south and east coasts of Scania, viz. from Trelleborg and Löde- 
rup (brought under culture in 1919 and from Vik, Vitemölle and Ahus 
(brought under culture in 1919) do not vary to the same extent. Cul- 
tivated material from the east coast farther to the north shows again 
some variation, viz. the set from Karlskrona, Blekinge (transplanted 
in 1920) and the set from Kalmar, Smäland (also transpl. in 1920), 
while the sets obtained north of Kalmar, viz. from Oskarshamn (in 
1920) and Västervik (in 1920) show but small variation. The same 
is also true of cultivated material from the interior, which includes 
series from Vombsjön (Öved) and Tollarp in Scania (brought under 
culture in 1919), from Jönköping in Smaland (cultivated since 1920) 
and from Flottsund, Uppland (cultivated since 1921). Besides the cul- 
tivated collections mentioned above, smaller ones comprising only few 
individuals have been grown from additional localities. Cultivated 
series collected in 1922 include material from several points on the 
Norwegian coast (Bergen, Aalesund, Molde), but these will not be con- 
sidered here at any length. 
In order to make clear the different degree of variability within 
cultures from different localities a few of the series are tabulated be- 
low. In the following table (table 6) the individuals from the Mar- 
strand culture are put together. 
The only character changed through the cultivation is the length 
of the scape and the leaves (not shown in the table). The other cha- 
racteristics typical of the different individuals have not undergone 
any observable changes during cultivation. Even such characteristics
