I took this photo as part of a reply on to the water in pitchers question on another forum. As stated there this is a small group of Sarracenia purpurea which have not had water in their pitchers for many many years. There are S. purpurea ssp. purpurea, ssp. venosa and ssp purpurea heterophylla in there and a few other bits and pieces. Not having water in the pitchers doesn't appear to have done them any harm as they flower profusely annually.
That's very interesting Fred. Presumably the traps do get prey within them?, but are to all intent and purposes are dry, in as much as no water is introduced from external sources. That would suggest that the inquilines must be still present and breaking down the prey in a dry trap state for absorption of the inorganic elements by the plant, otherwise they would not have survived as well as they have for the last years. Do you ever see signs of scorching on the leaves from excess nutrient concentration from dissolving prey?
S. purpurea is an awful carnivore without water in the pitchers Steve. I think the only prey I've ever seen them get are the very occasional slug, and I've no idea why the slug died in there. S. psittacina seems to do fine in collections and I doubt any of those catch prey unless they're semi-aquatic. I have a Slack hybrid which has an enormous mouth so it catches nothing, even a 747 could turn and fly out of it. That's been going for years.

dvg: Did manage to pack down seven pails full of fluffy fresh snow, but despite trying to compact the snow as much as possible and even doming each pail's surface with an extra scoop on top, once melted, the pails were far from being full

dvg: When one collects a bucket of water, he has himself a bucket of water, while a bucket of melted snow only yeilds a third of a bucket of water, at best

dvg: But that said, there is still no shortage of snow drifts here now in which to harvest fresh snow from

dvg: According to your forecast, it looks like after a sunny weekend, you'll all be seeing some good rain
