It was a day to have a potential last look at some beautiful old seawalls before they are torn down by the MRT development at Marine Parade Road but turned out to be a surprised encounter with a rare fern called Nephrolepis acutifolia. Thank you, Stuart Lindsay, for pointing out my initial mistaken identification. It can be found on a rain tree at Marine Parade Road and a few locations such as Portsdown and SBG. Considered as an endangered species in Singapore.

Seriously! I can't tell a different from other ferns if you do not point out! OMG!
wow! salute!
This is Nephrolepis acutifolia, not Lindsaea heterophylla which is a small terrestrial fern.
Thank you Stuart. You are correct.
The "wiry root" is not a root, but rather a runner, which is one way it propagates.
Hi, is this fern still around? Like to take a look but there's lots of MRT construction. Not sure which rain tree and hope it is still there. Thanks
