Sorry, photos are inadequate – everyone makes this mistake with tree-ferns, but to identify Cyathea species we need to see a close up of the underneath of a pinnule! This shows the hairs and little scales and make it possible to recognise which one it is.
I’m not even going to make a wild guess – it would be totally unreliable. Can the photographer throw a stone up at a leaf and get a little pit of pinna to fall off then make the close-up photo? Only then can it be named. Please try again!
Pl. send the details as requested by …
I think proper identification will be possible only if you can provide the under surface of the frond in a close view. From appearence of the plant and also from its place of occurrence, I think it may be Cyathea brunoniana.
