Nephrolepis acutifolia

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.

Appeal to Preserve a Giant Fig Tree at Limau Estate Neighbourhood

An appeal has been made to Minister Lawrence Wong and it is receiving attention from the authorities.

You can help. Please do consider nominating it as a Heritage Tree at the link here.

Endangered species: Ficus superba
LOCATION: Wooded area of Limau Estate opposite Tanah Merah MRT. designated as Land Parcel B by URA for development

A forest unto itself, this robust and healthy veritable giant stands at 25m tall and is
colossally-rooted with an impressive girth of 12m standing firmly on stable flat ground 7m
away from the edge of a 6m slope facing the MRT as a truly iconic landmark of Bedok / Tanah Merah.

Firstly, it offers little impediment to development as it sits right at the boundary of the parcel’s
extreme northern corner. Secondly, it is an endangered species in Singapore. Last but not
least, its magnificence is deserving of a heritage status that not only add tangible values to
the development but also retains the asset as a green lung to our community of Limau
Estate Neighbourhood and Bedok at large.

Galearia maingayi: Remembering James Franklin Maxwell at MacRitchie

It is a prized moment. A loveliness of being alone in the forest, that once you found it, you will never ever be alone. Where your joy finds an elegance smiling at you, filling you up and making you soft and mellow all over while standing taller than tall and never leaving you.

I have never felt a tree so elegantly expressing itself at flowering than Galearia maingayi.

Someone once said that elegance is not what you wear, but how you carry yourself, what you read... how true even for this tree! Like poetry in motion! Her long thyrsi-flowing-loveliness in the wind! Never mind its tiny flowers!

I am reminded of another elegance... one that stands out in its own way. Of a loveliness you see if you knew how to appreciate it. I am reminded of James Franklin Maxwell in his singularity of purpose... an elegance of the love of his art. His 1978 specimen of Galearia maingayi is the earliest known from MacRitchie forest in SING Herbarium.

It seems providence that I should find this exceeding rare tree at MacRitchie and take this unique opportunity to remember him here in the first anniversary of his death 12 May 2015.

Obituary for a profoundly intrepid botanist James Franklin Maxwell can be found here

Flowers in hanging thyrsi: greenish white... (EJH Corner 1936)

Magnificent male tree at MacRitchie forest
