Trent et. al.:
Interesting idea. I too have seen some problems with complex crosses, but
since I haven't done that many, I wrote it off to the timing of the
pollination attempt and lack of ideal post-pollination conditions.
The thing is, Neps and Sarrs. both tend to exhibit incomplete (or partial)
dominance of inherited characteristics. I don't know of any specific
reason for the lack of viability of these complex crosses. And in fact,
complex crosses seem to be successful for Sars. as can be seen by the
hybrid swarms in some locations in the wild and the success of Mellichamp's
hybrids like Lady's in Waiting, Dixie Lace, etc.
Anyone know of likely limiting factors that would compromise the viability
of a multi-parent hybrid?

-------(snip) -------Certain Nepenthes do
not like to be crossed with each other. It seems that once four different
species are intertwined in a cross, Nepenthes start to become difficult-
seedpods yield few, if any, seed, germination is nil to poor, and the
seedlings lack vigor.
Most Nepenthes hybrids are simple, and display wonderful vigor, but complex
hybrids are a different case. It seems crossing within a few select species
will carry further, but mixing widely varying species types seems to soon
lead to a near dead end. ---------snip-------- I believe this is a whole
new realm
