In addition to these climatic factors (elevation, geographical
latitude), also edaphic (soil, etc.) factors determine the endemism
of this most remarkable species. G.Kelam is an inselberg (an isolated
outcrop of siliceous rock). _N. clipeata_ (unlike other plants
inhabiting a similar geographical setting) is adapted to this
peculiar rock surface situation that is almost devoid of other plants,
so it is very unlikely that this species can be found somewhere in
the close neighbourhood of G.Kelam (i.e. in habitats in which it
would not survive competition by other plants that are more vigorous
in these more "normal" habitats). In fact the known specimens indicate
that this mountain is the only station of the species at all. It is
quite remarkable that this (almost?) extinct species was never
protected more than any other _Nepenthes_ (cf. N.mirabilis_!).
Kind regards
