Ornamental Fern for ID : Mumbai : 221011 : AK-2:
An ornamental potted plant, cultivated at Jijamata Udyan, Mumbai.
Picture taken on the 15th of August,11.
Fern leaves more than a feet long.


Looks like some species of Drynaria to me.
It is found in wild in the Himalaya.


WHEN YOU WANT A FERN TO BE IDENTIFIED! KINDLY TAKE THE PICTURE OF THE FERTILE FROND. IN THIS CASE DO YOU HAVE DIMORPHIC FRONDS?


It is the common low-altitude species of N.E. to S. India, Drynaria quercifolia. I wish could grow it as splendidly as this fine specimen – but our Winters kill it!


Yes I do agree. Here you can just see some of the backing leaves (what are they called, trophophylls, basiphylls or something) down the left hand side of the bowl, but it’s a bit hard to see. For Drynaria it would also help to see the rhizome.


I found one more picture of the ornamental fern.
Would this help?
Terms like the fertile frond, etc go above my head as I am not a botanist.

Yes, that certainly helps – very informative picture of the basiphyll, showing the very thick rhizome and scales typical of Drynaria quercifolia (Polypodiaceae).
Drynaria is rather a curious genus in having two types of leaves – the unstalked and less divided basal ones and the stalked, taller ones with nearly separate side-pinnae – and which may often become fertile (develop spores), unlike the basal ones.

This leaf was growing out of the trunk of a tamarind tree.
The base of the leaf seemed to come out of what looked like wet moss. Identify please.

This may be Drynaria quercifolia, an epiphytic fern.


yes it is Drynaria quercifolia 


Yes, Drynaria quercifolia. The “wet moss” is the scales covering the thick rhizome.

Thanks … The tree was very much alive. I have seen this growing on a number of trees of different species. Even on roof-tops over here.


Yep!  It’s beautiful right now, absolutely covering the trees in Assam.
