The plants I have seen from Borneo that possibly match your
description are referable to _N. veitchii_.

Why not an artificial one?

Why should that be unlikely?

The confused material I know is _N. veitchii_.

All these are more probably referable to _N. stenophylla_ Mast. (no,
not the plant Danser, Kurata, Turnbull et al. confused with this
name, which is _N. fallax_). I have never seen _N. stenophylla_
Mast. (non Danser) with an apical spur below the lid. I am not sure
if the true _N. fusca_ (from Kalimantan) is conspecific with _N.
stenophylla_ Mast (non Danser). If it is, _N. stenophylla_ Mast. is
the correct name for all _N. fusca_ material.

>, but there is still the problem of the above mentioned hybrid.

I suppose it is _N. * mixta_ with a wrong label. _N. northiana_
apparently did not survive at Veitchs' and (subsequently) at other
places but their weedy hybrid obviously did.

Kind regards
