plurilocular sporangia, hitherto unknown in this species, which 
were also immersed, but were quite different in form from those 
of P. latifolia. On the other hand, some quite small specimens, 
which occurred among the sporangia-bearing plants, and which, like 
these grew epiphytic on Halidrys, were pronounced by Kuckuck 
to be unquestionably Punctaria plantaginea, the young plants of the 
latter species having marginal hairs and closely resembling a Des- 
motrichum undulatum. 
I have further referred to P. latifolia the P. plantaginea of my 
preliminary list, which is by the way wrongly reported from Thors- 
havn it having been found in Kalbakfjord. On closer examination 
of the few dried specimens which were all I collected there, the 
thallus proved to be composed of two layers of cells only, and they 
agreed altogether well with Thuret et Bornet’s figure, 1. c. Lastly, 
a specimen of the P. plantaginea mentioned by Simmons (1. c. 
p. 270) of which he kindly sent me an example, on being examined 
more closely also proved to agree fairly well with P. latifolia , amongst 
other things in the fact of its thallus containing two layers of cells, 
but the specimen in question is unfortunately sterile. I also showed 
Dr. Kuckuck this specimen which he pronounced to be undoub¬ 
tedly P. latifolia.

Some specimens gathered by Ostenfeld from Trangisvaagfjord 
and by myself epiphytic on Laminaria near Arge, I have referred 
to what Kutzing (1. c.) calls Punctaria angustifolia. One of the 
specimens bore quantities of sporangia, a transverse section of 
which showed that they had exactly the same form as those in 
Kiitzing’s fig. (1. c.). The form of the plant also agreed well with 
Kiitzing’s habit illustration. 
Judging from its known habitats, P. latifolia occurs along the Faer- 
oese coasts in sheltered situations epiphytic on larger algae, e. g. Laminaria 
and Halidrys , and at no great depth. Fructifying specimens were found 
in May only. 
Found hitherto in the following places: — Ost.: Glibre (!); Str.: 
Kalbakfjord (!); Syd.: Trangisvaagfjord (Simmons, 1. c. mentions having 
found it abundantly on Laminaria saccharina and L. hyperborea)\ f. an¬ 
gustifolia has been found on Str.: Arge (!); Syd.: Trangisvaagfjord 
(Ostenfeld).

Found hitherto only in sheltered localities in the interior of 
fjords, or in the narrow sounds in which it occurs in the sublittoral
