The leaves on wild plants can be really very long, 40-50cm. They are narrower however than stuartiana or schilleriana, more like a big narrow leafed celebensis plant. Wild plants are rare nowadays. They grow very well mounted, though I prefer to pot phals in pot (all the species), because once they make a pot-adapted root system, they grow tremendously better. I potted some minus 2 months ago, now they have 3 new nice leaves, plenty of flower spikes, and the leaves are bigger. Same for lindenii, if you pot them, they'll grow much bigger and better.
