Sorry to disappear, I've been a little busy for the forum the last week or so. Here is the latest new flower. The plant is Cryptocoryne elliptica "Perak: Pondok Tanjung". The wet leaf litter soil is amazing stuff.
Sean, I haven't tested the pH in a couple of months, but it has always been neutral. I don't have the real test kit. A buddy has access to quality equipment and he tests it for me.
I haven't had much chance to chat with Ted lately. I'm guessing dissection of that flower is like performing surgery on a ladybug. He likes a challenge...
The ideii, that’s a beautiful plant. It would be fun to get a flower on that one.
Propagating elliptica isn't difficult once you gain a bit experience. Try placing the whole leaf (petiole as well as whole leaf blade) onto really soggy soil and make sure that humidity is 100% (don't try to plant the base of the petiole into the soil since this is not necessary). I usually have it covered by some mm of water but algae might be a problem with your soil mix... The plantlets can also develop under algae, so don't despair if this happens (it just slows things down and you have to look carefully after some weeks).
