Glossostigma and other NZ native aquatic plants...
After seeing a mention here that Glossostigma (as used in Nature
Aquarium World) may actually be a native New Zealand plant, I did
a wee bit of investigating.
Previously unknown to me, it turns out that the patron of our
local aquarium society (who I hadn't met before) is the aquatic

lakes that I'd probably find some in, and I was planning on going
on an expedition one weekend.
This morning I got an email from him saying he was at a river
yesterday that had some cool aquatic plants (including
Glossostigma) and he had collected some for me. His base is just

He has heaps of troughs with various types of aquatic plants, and
he gave me a few samples to try growing. Among others: a type
of native floating fern - Azolla rubra?; a couple of types of

like orange buds); a native Potamogeton; a native species of
Lilaeopsis, L.ruthiana, which has cylindrical, tapering leaves
(looks heaps cooler than the more flattened leaves of

Plants For Use In Aquariums And Ponds" at the recent Aquarama in
Singapore. He's sent me an electronic copy, so if there's
interest, I could whip it into HTML suitable for putting on the
I'm also going to send him the info on how to join the mailing
