rhizomes and together with various other 
loose Alge. As it has been found only 
in the inner Danish waters and the adja- 
cent part of the western Baltic Sea and, 
according to J. AGARDH, at the coast of 
Bohuslän, it must be extremely probable 
that it might be a loose sterile form of 
any of the species of Phyllophora occurring 
in these or the adjacent waters, and I many 
years ago had arrived at the conviction that 
this species was Ph. rubens'. An examination 
of a large amount of material from various 
localities has fully confirmed this opinion. 
Firstly it must be pointed out that the 
colour and the consistency are identical 
in Ph. epiphylla and Ph. Bangii; and none 
of them adhere to the paper when drying. The area of the latter does not coincide 
with that of the genuine species but is situated outside it (9: more to the south 
and west). Near the boundary between the two 
areas loose forms occur that are only little incised 
and then much resemble genuine specimens of 
Ph. epiphylla (comp. Fig. 524 B—D). The fronds 
of these specimens are partly linear with the border 
entire in part of its length. Similar specimens 
may also be met with in the waters north of Fyn. 
The specimen shown in fig. 525 has a great com- 
plex of shoots with entire borders springing from 
a shoot with the usual incisions; the first agrees 
exactly with a narrow specimen of Ph. epiphylla, 
1 mm broad. The specimen represented in fig. 526 
is also very instructive; it shows the proliferation 
characteristic of the species and a feeble mid-rib, 
and further the linear segments of the frond with 
border partly entire partly more or less incised. In 
the specimens agreeing with the typical Chondrus 
Bangü Lynes. the broader parts of the frond are 
always present but are usually shorter and provided 
with feebler or deeper incisions, and a midrib is 
never present. Fig. 524 E shows a well developed 
specimen of this form; some of the lateral shoots 
are narrow without broader parts.
