260 GOTE TURESSON 
In certain places on the western coast, where an abundance of 
other species of the genus, such as A. Babingtonii and A. latifolium, 
occur, hybrids between the west coast type and these latter species be- 
come so frequent that it is sometimes difficult to find typical indivi- 
duals of the type in question. This is the more remarkable as cases 
of vicinism have been very few in my cultures (see above). Different 
forms of the type might behave differently as to the mode of fertiliza- 
tion. The relatively late flowering probably favours a certain degree of 
hybridism with other species. The western type flowers late enough 
to find particularly early individuals of other species flowering at the 
same time. 
The northern limit of extension of the forms belonging to this 
western type has not yet been determined. They have been found to |

be common at least to the middle part of Bohuslan. Undoubted inter- 
mediates between this type and the Sound type have been found this 
year at Helsingborg. Their behaviour will be followed in cultures. As 
to the systematics of the forms belonging to the western type of A. 
sarcophyllum the name A. hastifolium Salisb. has been adopted to co- 
ver the group (by LiNDMAN, 1918). The name A. patulum var. sarco- 
phyllum Neum., covers some of the forms characteristic of the type. 
5. MATERIAL AND CULTURES OF INLAND AND COAST 
FORMS OF SEDUM MAXIMUM (L.) SUT ER. 
The material of Sedum maximum comprises about 300 individuals 
transplanted from their natural habitats and new growing in the ex- 
perimental field. They come from Bohuslän, from Halland, from se- 
veral points in Scania, from Smaland and from the islands off Stock-
