not found it higher than 9 cm. In the inner Baltic Sea Sveperıus found il 
scarcely more than 10 cm high. He refers the plants here found to f. minor 
Agardh, a form differing only by smaller dimen- 
sions, in citing Fl. Dan. tab. 393 and AREscHouG, 
Alg. Scand. exs. No. 257. In the most feebly de- 
veloped specimens the erect shoots are not bran- 
ched, or but little so (fig. 90). — Furcellaria grows 
usually on stones or pebbles, but may also be 
found fixed on other Algæ, as Phyllophora, Chon- 
drus. In some places north of Fyn (especially aZ, 
near Fyns Hoved) it was found growing in com-

first loose or originally fixed at this stationary bottom. In other places detached speci- 
mens lying loose on the bottom are met with, often in great quantities, particularly 
in fjords, as Limfjorden, but also in the Kattegat, e. g. around Anholt. It is appa- 
rently able to live long in this condition, for plants in which the under part is in 
a state of disorganization are often met with. Some of these plants are not much 
different from the normal ones; in other cases they are more branched, and form 
globular bushes corresponding to those mentioned by REINKE (1889) and SvEDELIUS as f. 
ægagropila (fig. 91). 
The species 
has been found in 
depths from 2 to 28 
meters and once in 
38 m depth (near 
Bornholm). It is of- 
ten a predominant 
element of the vege- 
tation, particularly 
in depths of 4 to 15 
m. It is perennial, 
but the fructifying 
shoots are shed in 
winter. In sunny lo- 
calities the upper 
parts of the fronds 
are green in sum- 
mer.
