At least this difference is easy to observe (and thus used by most authors).

The picture (drawing) in DANSER was prepared after the original material
from G.Kemul (L!, BO).

I fear the matter is not that simple! ADAM & WILCOCK have added the species
_N.faizaliana_ to this complex, hybrids do almost certainly occur, and it
is still not clear if _N.maxima_ does exist in N Borneo (OK, they are all
in some way related to _N.maxima_ but does the true species occur there?).
So just a "bit of revision" will probably not be sufficient.
Kind regards
