strip seems to indicate that the A. litorale types inhabiting this coast 
strip differ genetically both from the plants typical of the Halland- 
Bohuslän coast and from those of the Sound region. 
B. ATRIPLEX BABINGTONII WOODS. 
This species occurs along the west coast as far to the south as Kul- 
len. It is only found sporadically along the Sound. It has also been found 
quite typically at Stenshuvud on the east coast of Scania, and occurs 
- Fig. 19. Atriplex Babingtonii. Ascending and procumbent types. 
likewise on Oland and Gottland. The plant has a deep-ground root- 
system and generally occupies the upper supralittoral belt of the beach. 
A number of biotypes have been isolated from this species also but no 
differences in the geo- 
graphical distribution 
of the types have been 
found. Populations 
from Bohuslän, Hal- 
land and Gottland show 
the same mixture of 
types as to branching 
habit, leaf margin, 
bractlets, etc. Auto- 
gamy does not seem to be the rule in this species. In all localities 
where A. Babingtonii co-exists with other species of the genus, for in- 
stance with À. latifolium Wg., hybrids are found. The hybrids are in 
fact much more common on our west coast than A. Babingtonii itself. 
It is only in places, where the zones of the beach for some rea- 
son or other are devoid of other Atriplex species, that A. Babingtonü 
is found in its typical form.
