I have looked and looked, but it seems that nobody in the US has Piptospatha
for sale. I think it would take a special import to get that one in.
There are Borneo species of Schismatoglottis
, but those genera also occur over a wider area. If you wanted to have a totally authentic selection you would need to research the species that are Borneo native.
I have this Scismatoglottis
'Frosty Kiss' which is a real nice riparium plant. That 'Frosty Kiss' is just the variety name and I lost track of the species, but I am pretty sure the species is from Malaysia and not Borneo.
