A few general questions for the group: My aldrovanda stays about 4-5 inches
long. It continues to produce new whorls at the growth end but the far end
dies off at about the same speed. This doesn't seem reasonable to me, any
ideas about how to help it out?

I also noticed Jan's comment about the Cuban species, D. moaensis and the
presence of D. intermedia and D. capillaris. Do the southern-most examples of
D. intermedia have a dormancy where they form a hybernaculum? As for D.
brevifolia, can it be reliably distinguished from small forms of capillaris by
the hairy or tentacled scape?
