It appears to be epiphytic. Is it?


Yes sir, it’s epiphytic but some times lithophytic also.

Psilotum nudum (L.) P. Beauv.SN23420 : 3 posts by 2 authors. Attachments (1)- 3 mb.

Psilotum nudum (L.) P. Beauv. Is a wild lower group fern from Western Ghats Tamilnadu. It is my old collection when I was studying my post graduation (35 years before) 

Yes – but few in India seem to have kept up – it is not a Lycophyte, but a simplified fern! More advanced not so “lower”.

PSILOTUM NUDUM: Pachmarhi is a paradise for botanists. During my stay at Pachmarhi at different times I met lot many botanists and budding botanists at Pachmarhi, who came on excursion. One particular plant specimen they were interested in was Psilotum nudum. I found the same plant on the trunk of a Polyalthia longifolia tree. Attaching an image of the same. 


Can’t see it – need to post good, clear photos in focus.  P. nudum is widely distributed in India.
