Glossostigma and other NZ native aquatic plants...

Hi all,

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

Glossostigma) and he had collected some for me.  His base is just

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
