ering has commenced, but it is mentioned here as a proof of the 
hereditary nature of the characteristics involved. 
The different hereditary forms of Matricaria inodora transplanted 
from various places are thus found to group themselves into the follow- 
ing types according to the habitat: 
a. The inland type. This is an annual weed with an erect habit 
of growth. The leaf segments are long and thin. Only known as an 
anthropophyte. 
b. The type of the west coast. This type includes perennial, 
halophytic forms with thick, short and blunt leaf segments. They are 
more or less depressed and have a bushy growth. The rays of the 
flowers are shorter and broader than those of the inland type, and the 
bracts have a broad and dark coloured margin. There is moreover 
a great variation within the type, involving hereditary cies as 
to morphological details of leaves and flowers. 
c. The type of the east coast. This type includes perennial, halo- 
phytic forms the leaf segments of which come between the inland 
type and the b-type in point of length and thickness. While most of 
the forms of the b-type are prostrate or procumbent, the majority of 
forms belonging to this type are ascending. 
It should be added that in places where cultivated fields run down 
to the shore bastards representing different combinations of the inland 
and the halophytic types might be found. 
C. LEONTODON AUTUMNALIS. 
Sets of this plant have been collected from beach habitats as well as 
from the inland in 1919, 1920, and 1921, and important differences are 
seen in the cultures between some of these sets. This is particularly 
true of the series transplanted in 1920 from the coast at Kullen and 
Arild (N. W. Scania). The plants included in these series are all 
smooth with coarsely dentated or nearly entire leaves. The plants 
making up the series transplanted from inland meadows in Scania 
have mostly pinnatifid leaves, usually somewhat hairy. These plants 
are also taller than the coast plants. The cultivated coast plants from 
Kullen and Arild, furthermore, have been found to flower about. two 
weeks before the inland plants. Clones have been raised from indivi- 
duals of these different series. Fig. 13 (to the left) represents an in- 
dividual from a clone obtained in 1921 by dividing a plant typical of 
the Kullen series (transplanted 1919), while the plant to the right
