I had a stowaway on my last order of plants, and I was wondering if someone could help me ID it. It is thread-like--no apparent roots. Every 1\4 inch to 3\8 inch there is a node, with a couple of hairs (leaves?) and a bubble or bladder smaller than a pinhead with some very fine hairs. It is apple-green, and just floats around catching on various leaves, etc. Any ideas? Bob Sumner ernesth at infi_net
