«A Report of a botanical Journey at the Neighbourhood of lake Fæmunsøen»
– rediscoveries and new plant discoveries in the footsteps of the old master.
In 1865 the botanist H.L. Sørensen made a journey through Trysil, Engerdal and Røros municipalities. In this
article the flora along Sørensen’s route through Engerdal municipality with a detour to mount Sølen in
Rendalen municipality is described. Before the Second World War O. Nyhuus, H. Resvoll-Holmsen and G.
Samuelsson obtained information about the flora in this region, too, while R.Elven, F. Wischmann and A. Often
have made the important contributions to the area’s flora in the period since the Second World War. In 1998
the data base «Hedmarks karplanter» (hereafter referred to as dH) was established and includes all current
information regarding plant collections from Hedmark county found in the herbariums at the Universities of
Oslo and Trondheim.
Table 1 summarises all new plant discoveries from Engerdal municipality, in Sølendalen in Rendalen
municipality and in the northern part of Trysil municipality that were not previously included in the database
(dH).
Table 2 presents a plant geographic characterization expressed by plant geografic elements. Only a
selection of characteristic species mentioned in the text are taken into account. The eastern element is
obviously present. The most interesting group is, however, the alpine plant group, showing surprisingly
many species which occur at their southeastern limit in Scandinavia in this region. Northern boreal species
that seldom exceed the timber-line represent a north boreal element. Five species that demand relative high
humidity are gathered in a suboceanic element. These species find humid niches on hillsides and in mountain
snow beds. The termophilous element consists of species that are hardly found above the mid-boreal zone.
These species find their warm niches on southfacing rocks, arid meadows, mires and in watercourses.
The alien species group contains all alien species mentioned in the text.

Den gamle mester ...
«Sommeren 1865 erholdt jeg [….] et Reisestipendium
i det Øiemed at undersøge Omegnen af Fæmunsøen
og Trysilelvens Dalføre i botanisk Henseende.
Aarsagen, hvorfor jeg valgte denne Egn
til mine Undersøgelser, var ikke den, at jeg her
haabede at høste noget rigt Udbytte, hvilket de
bekjendte geologiske Forhold ikke tillode mig at
haabe, men den Omstændighed, at dette var den
eneste Egn i Christiania Stift, som ikke var bereist
af norske Botanikere.»
Dette skrev stud. real., senere konrektor ved
Kristiania Kathedralskole, H.L. (Henrik Lauritz)
Sørensen (1842-1903) i 1868 etter at han som
første fagotaniker hadde trengt inn i de geologisk
fattige sandsteinområdene ved Femunden. Botanikere
hadde allerede i et halvt hundreår valfartet
til de artsrike kalkområdene på Dovrefjell. Den
unge student Sørensen måtte søke øst for fjellene
for å finne jomfruelig mark for sine botaniske studier.
… men ikke den eneste
I begynnelsen av 1860-årene gjorde Olinus Nyhuus
sine første botaniske iakttagelser rundt
hjemgården i Trysil, et arbeid han skulle fortsette
med i over 70 år. I 1936, i sitt 92. år, fikk han med
