Sphaeropteris intermedia (Cultivated- USA)

Sphaeropteris intermedia (Mett.) R. M. Tryon (syn: Alsophila francii Rosenst.; Alsophila intermedia Mett.; Cyathea francii (Rosenst.) Domin; Cyathea intermedia (Mett.) Copel.);

New Caledonia as per Catalogue of Life;


A palm seen inside the Conservatory last month.
Kindly help in id.

i think tree fern; Cyathea sp.

Thanks for the suggested id.
Could be Cyanthea cooperi? Just a guess.

Quite right to send it to me - of course "that ain't no palm", but a tree-fern! Cyathea species do, however, need a close up of the underneath of a pinnule to show hairs, small scales etc. My guess is it might be C. spinulosa, but that is itself a species-pair with a closely related cryptic second species - so the close-up is needed.
