saxatile, with its var. pusillum. In more marshy localities, 
many forms of Carex cespitosa abound, as does also Hquise- 
tum limosum. Occurring also on the moors .and marshes, 
but met with in greater profusion on the roadsides about 
Reykjavik, e.g., on the road to the cemetery or burying- 
ground to the south-west of the town, are such common 
British lowland plants as Ranunculus acris and repens, 
Rumex acetosa and Acetosella—the latter in beautiful flower 
—Cerastium vulgatum and Stellaria media. A delicate form 
of Anthoxanthum odoratum is common on the moors. Among 
the shingle on the beach to the west of the town Glaux mart- 
timais abundant. On the banks of the Lax4, or Lax-elv (the 
- Salmon River of British tourists), about the Falls and Salmon 
weir I found our common Spirea Ulmaria and Geum rivale. 
And on the Havnafjord lava field, growing luxuriantly in 
crevices of the old lava on the heights immediately behind 
the village, I picked tufts of Saxifraga cespitosa, Draba 
incana, Arabis petra and Viola canina var. flavicornis, Of 
the alge found on the coasts, none were so abundant as 
Desmarestia aculeata. I found it in immense tangled masses 
on the shore about Reykjavik, but in greatest profusion in a 
little bay midway between Reykjavik and Havnafjord. Mr 
‘Croall tells me that this is “a very common plant in the 
North Atlantic, at least on its eastern shores, and is perhaps 
scarcely less so on the shores of the Pacific, and even in the 
Southern Ocean, where it is represented by forms very nearly 
allied, if not identical, D. media, &c.” I found also almost 
everywhere on the shores about Reykjavik, Laminaria digitata 
and saccharina, Fucus vesiculosus and serratus, Chondrus cris- 
pus, Wormskioldia sanguinea, and other alge quite as familiar 
on our own coasts, and which appear to be known to the Ice- 
landers under the common name of “Tang” (a word very 
near the “ Tangle” of our own Newhaven fishwives). In my 
Bibliographical appendix (No. 19) will be found mentioned a 
special dissertation, by a native Icelander, on the economical 
applications of the Icelandic alge (“Tangarter”). Of the 
mosses, by far the most common—so common, indeed, as to 
give a tone to the more minute features of the landscape—is 
the Lacomitrium lanuginosum. It is especially abundant on
