One paper I remember was on the (flavonoid?) components of the perianth and
phylogenetic relationships of _Sarracenia_ spp. between each other by
SCHNELL in Castanea (?, have to check).
But the original question affected:
>>relationship between Nepenthes and Sarracenia?
and not evolution within _Sarracenia_.
Kind regards
