Fern from Mt Slamet Central Java 2<\/a>:
\nCould you validate the ID of our ferns please.
\nIs it Angiopteris evecta<\/em>?
\nIt is a short stemmed fern.
\nFronds 2 – 4 m long, stalk looks smooth, green, 3 – 4 cm diameter.<\/span>
\n2000 m alt.<\/span> Thank you.<\/p>\n

The big <\/span>Angiopteris<\/em> from Gunung Slamet<\/span> appears to be<\/span> A. palmiformis<\/em>, 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!
\n<\/span>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.
\n<\/span>If so, the recurrent false veins, which are important in <\/span>Angiopteris<\/em>, 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 <\/span>A. helferiana<\/em>.
\n<\/span>A. palmiformis<\/span><\/em> 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.
\n<\/span>A. evecta<\/em> 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 “<\/span>A. evecta<\/em>“, but as Holttum showed, that was incorrect.
\n<\/span>The other difficulty in <\/span>Angiopteris<\/em> 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 <\/span>Angiopteris<\/em> is a difficult genus with quite a number of species, three in India, too.<\/span><\/p>\n<\/div>\n
