As will be seen from the fiora-list there were found
altogether 147 species of phanerogams and pteridophytes
in the area investigated. This is not a small number con-
sidering that the whole area was from ab. 600 m. to 1000
m. above sea-Ievel (Landmannahellir 608 m., Laugar 624
m., Kýlingar and Jökuldalur 598 m.). Having deducted the
18 species which were only found in such places as there
was subterranean heat in Hattver and Laugar, we still
have 129 species left. Two more species, Stellaria media
and Capsella bursa pastoris, which were only found at
Landmannahellir, may further be deducted as they have
undoubtedly been carried there by travellers and been able
to thrive there because of manure which is in the cáve
and around it. There are then left 127 species of which it
may be said that they have their habitats at Fjallabaks-
vegur or above the altitude of 600 m. Some of the plants
