Hey Folks,

Randy Palmer's note (included below) reminds me of how I've often been
intrigued that CP can grow so close to large bodies of salt water.
_Nepenthes_ can grow just a few meters from the ocean, plants of the
southeastern US can survive inundation by ocean swells, and I've seen
Italian _Pinguicula_ growing just a few meters above the high tide line.
Yet common sense tells us that salt will kill them. Very interesting. I
wonder if CP can live in salt areas as long as there is sufficient
groundwater flow of fresh water to overwhelm the occasional salty
experience? For example, the _Pinguicula_ I mentioned were growing on a
vigorously wet, dripping cliff above the water.

In graduate school, I once watered all the _Nepenthes_ in my office
terraria with bottled water, just to discover my office-mate was using my
water bottles to make brine for his saltwater aquarium. Yes, I watered all
my _Nepenthes_ with the equivalent of seawater! I spent a few hours
flushing the plants, and despite the fact they were sitting in saltwater
for several hours, they survived the ordeal just fine.
