Dear Matthew, dear Joachim, dear Jan (and everybody else interested
in Nepenthes taxonomy),

I completely agree with Joachims thoughts about Nepenthes taxonomy as
outlined in yesterday's mail.

Please let me comment the following:

H. Rischer, B. Baumgartl, B. Kistler and myself visited Doormans Top
this spring. We searched at the supposed altitude quite intensively
but found nothing except N. vieillardii and N. maxima. However I must
admit that the type collection was made on another slope of the
mountain. As Doormans top is completely intact without any burning or
logging I do not think that the species is extinct. Comparing the
ecology of Doormans top around 1400-1600 m with the N. neoguineensis
site near Jayapura you find completely different ecotypes. As Joachim
mentioned Doormans top's mossy forest is quite different to the
forest near Jayapura where N. neoguineensis grows together with N.
On the other hand after having seen them in the wild I completely
agree with you, Matthew, that even the
most infundibuliform pitchers near Jayapura still are without any
doubt specimens of N. neoguineensis.
>From my point of view we will have to wait until material from
Doormans top is recollected.
