Martin Zevenbergen asked me for Sarr. purpurea sites in Switzerland in
early summer but I forgot to answer him (sorry Martin). I will send you
pitcher fluid of these ex situ plants next summer and I'll try to find out
when they were introduced here (as far as I know it was in the last
century). I think it makes a difference whether seeds were introduced or
living plants (in the last case parasites/symbionts would be likely to be
introduced too). I guess it's impossible to find out for sure which stage
of the plant was introduced and where the material came from. Let me know
details concerning the material you need.
