SYNANTILY IN THE GENUS LONICERA. 473 
may give rise to a false synanthy. So far as I am aware, this 
occurs ouly in the case of ZL. cerulea, though it is not impro- 
bable that other species may eventually be found which possess 
this character. The false synanthy in LZ. cerulea is effected 
by the union of the two gynecea in certain planes with the 
bracteolar sheath, the gynecea themselves remaining quite free 
from one another. The fruit in this species is a pseudocarp and 
a false berry, in which the bracteoles as well as the ovarian walls 
contribute to the pericarp. 
There can be little doubt that there is some special biological 
significance expressed in the false berries of ZL. alpigena and 
L. cerulea, and that these forms of synanthy, although morpho- 
logically distinct, are both adaptations to some particular con- 
ditions of the plants’ environment. What these conditions are, 
in the case of these two species, are questions which can hardly 
be answered without a special study of the subject. It would 
seem possible, however, that the adaptations have some connec- 
tion with the alpine conditions under which these species thrive.
