Sporophyte : Sorus not found


Blechnum sps. , possibly Blechnum orientale.


No, that’s Blechnum orientale. The only generally similar Pteris is P. vittata (subsp. vittata in Kamrup), which has more, more crowded and narrower pinnae and only gradually reducing at the base, not suddenly so (and young fronds are not pink, then yellow, as in the Blechnum). When fertile they are easy to distinguish as the Blechnum has sori a bit apart from the costa, not at the edge as in P. vittata – but these photos are only young, small plants so not fertile yet.

However, I wish validation from …


blechnum orientale


Sterile fronds, sori not shown, frond upper part – not the characteristic base. Almost no diagnostic characters shown in the photo!

See Khullar vol. 2, pg 474-475 (2000).
How about running through the books and seeing if you can identify some of these things yourself, with a tentative name?  Take the next step!

Sorry I could not capture as expected.


To me looks different from images at Blechnum orientale 


If that’s the same poor photo without bases shown, yes, I did already identify it as B. orientale.
