Ptisana oreades (Domin) Murdock,
(synonym: Marattia oreades Domin),
(misapplied name: Marattia salicina Sm.),
(Marattiaceae fern plant family – European–ethnocentric–origin Australian taxonomic botany science names).

I welcome requests for permission for use of these photographs and videos;
and for the original high resolution photographs - videos, which have full EXIF data,
including full date-time made and my custom added tags of species name(s) and phenology observations words eg. "Ptisana oreades; fronds; pinnae; sori;".

No assumptions of my granting the request.
It depends on your showing your ongoing track record of respect and right ways responsibilities.

Photographs and videos times made, here are eastern Au standard times.

These photographs and videos carefully made with a mere Canon IXUS 190;
which includes the built in functionality of the optical zoom, up to 10x, and the macro focus (close-up),
with a decent quality lens considering it's only a small camera and 20 megapixels.

@andymurdock would you check this ID please, when time permits! – April 27th .

@macropneuma It appears to a P. oreades that's had a bit of a rough life. It's small, pinnules are somewhat misshapen, but it still has the general look and leathery pinnules of P. oreades and there's no other good option for the region. – April 29th .

Thank you Andy Murdock, much appreciated.

This beaut' small plant grows up the lower slopes of a steep hill,
under the dense canopy shaded south aspect here,
in unusually fertile soil for this region
and 10+ m above a steep creek.
So probably much drier and a bit rougher life for it than usual growing on the bank of the creek with roots accessing water.

I have to read the global taxonomy articles of Ptisana more, sometime.

Best,
Jason.
