Back to Tuas

As I was heading back school anyway to bring back my laptop cooling fan, I decided to just go down Tuas to visit the pitcher plant haven which LK brought us to last time.

Here is my cooling fan, nice right?

With the opening of Joo Koon MRT, I can reach the destination faster. This place is pretty much a wasteland visible from these common shrubs and trees like the Simpoh Air, Dillenia suffruticosa,

the common Acacia (Acacia auriculiformis),


and Singapore rhodedendron (Melastoma malabathricum).

There are also lots of mangrove ferns (Acrostichum aureum) here.

Weedy plants like this climbing Morning Glory (Ipomoea cairica) also bring a beautiful identity to this place.

I realised that I had missed this small but common plant, Cassytha filiformis. The picture above shows the flowers.

This is a parasitic plant and you can see the bulbous like structure that is attached on its host. These are the haustoria that penetrate into the host and suck water and nutrients from them.

These yellow ones also belonged to the same species. There were so many of them like green and orange threads running through the grasses.


It was only a short distance later when I reached this pool.


Here is the place where lots of Slender Pitcher Plants (Nepenthes gracilis) are found.


And more!

Found one that is floating on the water surface.

Here is another cute tiny one arranged in a rosette.


These numerous elongated structures are the developing fruits of the pitcher plant.


Most of us should know that the pitcher is a pit fall trap which ‘digests’ and absorbs the nutrients of animals. However, some other animals like the crab spider above makes use of this trap by just waiting there for unsuspecting victims to fall in.


I found two ground orchids here today. I love the fact that they are not planted and can be found in their natural habitat. This one is Spathoglottis plicata.


Here is the other one, Arundina graminifolia.


It is known as the bamboo orchid because, I suppose, the leaves look like those of the bamboo.


Seems like this place has not changed much from the last time and the construction has not penetrate the pool yet, even though lying adjacent to it. Anyway, I made an error in my previous entry, because the dirt biking race is actually located further down and completed by now. It is called Circuit@Tuas.

Tuas Marshlands

An initial plan to go Sungei Buloh was changed to the Tuas marshlands; the enticement was to hard for me to resist, even though I was busy doing some assigments. Thanks Ron for telling me of this change or I would have miss this trip, and LK for organising!

I first read about this place through BESG blog when they announced the reclamation of this site to give way to a racing course for bikers. Subsequently, another more recent entry of LK's trip on the Red-wattled Lapwing.

One of the first photos I took before we reach the wetlands the ground orchid, Spathoglottis plicata. Its name probably says it all, being able to grow from the ground rather than being epiphytic like most orchids.

Today was actually a trip for LK's student to do their dragonfly study. This picture will explain why theres so many dragonflies around.

They live around wetlands because their larvae are aquatic. Above shows a damselfly nymph, a close relative to the dragonflies. The three spikes on the back are their exposed gills, one characteristic to differentiate them from dragonfly nymphs.

A lesson from LK, female dragonflies can release their eggs prematurely when stressed, probably as a strategy that at least they might have a chance of surviving if the mother is caught by a predator. The green ooze are the egg clumps.

LK told us that the Nannophya pygmaea dragonfly is one of the smallest, I think in Singapore. Not sure if its the smallest in the world though. The above is a male. The female has white and yellow strips on the abdomen, can see from my new flickr acc :)

I didnt take many pictures of dragonflies, so hang on for Ron and others for their entry. But think after today and looking through some of my photos, think must agree that they are a great subject for photography :D

What a wonderland this place is for pitcher plants! The slender pitcher Nepenthes gracilis was just all over the entire marshlands. Even this beautiful red color variant above is in such an abundance. These pitchers are the ground pitchers, and easily differentiated from its more pronounced "wings" or fringes running down from the lid, probably as a guide for insects to crawl in to their death.

Heres a picture of the upper pitchers.

Pitcher plants are carnivorous plants (prob everyone knows that) and they secrete nectar to lure their prey into a pit of digestive juices. But some (lazy) animals make use of this lure to capture food for themselves, like the crab spider above, that lives exclusively in pitchers. Not sure of the ID though, does anyone knows?

LK showed us another carnivorous plant, the bladderwort (Utricularia gibba). I had heard of this for sometime, but never had the chance to see it till now. The tiny filaments of this aquatic plant carries many nodes or "bladders" (the black dots seen on the finger) which are able to trap tiny animals for its own nutrition.

And the reclamation works which are already being carrying out. Part of the race track is already accessible as we saw bikers playing round the obstacles in the near vicinity. Its pretty sad that to imagine such a wonderful habitat will be gone soon, together will all the pitcher plants, bladderworts, orchids, dragonflies and another habitat for the birds.
