Epiphytic fern in Sikkim:
I think this is Polypodium angustatum
Its seen on the tree branches. in East & South Sikkim, up to 1200 MSL altitude.
This is Pyrrosia adnascens – a close relative of P. lanceolata, but larger fronds, weaker indument beneath and sometimes more sterile-fertile dimorphic in frond-length (but often no more so than in P. lanceolata). It appears to be a distinct species.
The thick leaved epiphytic growing on Mango tree
It looks like Drymoglossum sp.
Can it be Drymoglossum niphoboloides?
This is again Pyrrosia adnascens – one has to be a bit careful when P. adnascens is smallish like this – as it then gets a bit hard to distinguish it from P. lanceolata (and leaf dimorphism is of no taxonomic value between those two, unlike what you will often read).
