A reply:
"The big Angiopteris from Gunung Slamet appears to be A. palmiformis, I
would think, though I hestitate as we still do not have a useable list of
Javan pteridophytes as far as I'm aware - and as I saw from visiting Gunung
Ged and the south, things can get complicated in the fern paradise of
Java!
But the huge size, smooth stipe, pinnae with very many pinnules and in
particular the pinnules having a cordate base, all look like that species.
If so, the recurrent false veins, which are important in Angiopteris,
should go to at least half way back to the pinnule midrib, or a little
more, before becoming indistinct. The sori are a little bit inframarginal,
not unlike our common Indian A. helferiana. A. palmiformis also occurs in
far N.E. India - in Arunachal Pradesh and adjacent Assam - and right
through from Myanmar and S.E. Asia to the Philippines.
A. evecta is neither present in India, nor Java, but confined to Oceania -
described from Tahiti - its recurrents reach the costa, among other small
differences. In the past all were just called "A. evecta", but as Holttum
showed, that was incorrect. The other difficulty in Angiopteris is the mass
of pointless synonyms made by C. Presl, de Vriese and then Hieronymus and
Ching - some authors, from Christensen onwards, have already cast doubt on
them and many have been sunk now. But Angiopteris is a difficult genus with
quite a number of species, three in India, too.
