I found this list on another site.
Spatterdock, Java/Lace Ferns, Java moss, Dwarf Lily, Vallisnerias, Ruffle Swords, Cryptocorynes, Jade Swords, Rangeri Swords, Dwarf & Tall Subulata Sag, Red Melon Swords, Heteranthera, Didiplis Diandra, Hygrophila, Rotala Indica, Anubias, Ruffle Sword, African Bolbitus, Ozelot Sword.
The plants I have tried which have survived high temps are Nymphaea stellata, dwarf sags, Vallisneria americana, Javan fern, Javan moss, Cryptocoryne crispatula, Cryptocoryne becketii, Anubias nana, Cabomba and Elodea densa(that was a surprise considering it tends to thrive best in colder temps).
Sadly, several of my plants are no longer in my tank due to problems like penetration to silicon sealant(as previously mentioned in my thread) and fish eating them quite fast.
There is one plant which can be seen in the discus habitats. It's Eleocharis(commonly sold in lfs as hairgrass).
