Let's collectively drool!

Finally, I found this plant from local professional aquascaper. Sorry, I still don't have the picture yet. I'll try to get it soon.

It comes from Timika, Irian Jaya, Indonesia

I've tested sporangia from a submerged leaf under a microscope. The sporangium capsule functions in exactly the same manner like these of the most other so-named leptosporangiate ferns: remaining closed when wet, but ripping open and throwing the spores away when drying. M. pteropus is described as growing under water level fluctuations in their natural habitats (mainly streambanks). Therefore the spores are probably released only when the water level decreases.
EDIT: Sori on submerged M. pteropus seem to be common (but possibly not all variants of this species). Maybe this is an adaptation to fluctuating water level. The development of inflorescences by submerged Anubias seems to be a similar case.

Sorry to raise a dead thread, but does anyone have a better photo of this mysterious "narrow leaf tropica" java fern that everyone is talking about? I know CS posted one, but it is kind of a dull photo (no offense).

I'll post some pics of the submersed forms later, it looks somewhat different, mos definitely not as "horny"

you da man Chase! No matter what Ken says about you, you're alright.

I think calling that one "narrow leaf Tropica" wouldn't be right though. I highly doubt they have anything to do with it.

Compared to the pics that I've seen in the past, this plant is MUCH larger... Is this the same plant from the year prior?

I also would'nt be surprised that the plant in the pic I originally posted and this thing you've posted are two different things. Microsorum is a huge genus.
