Nature Walk Series
Upper Seletar Reservoir
28 September 2013


Prompted by a friend that a rare Artocarpus dadah (Green Tampang) tree was being cut down at Upper Seletar Park, I decided to pay a visit to check out exact location. This tree species is a relative to the edible Jackfruit (Artocarpus heterophyllus) and Chempedak (Artocarpus integer). photo photo At the end, I did not find the remnant of the cut-down tree. The tree was probably there for a long time though I had not noticed it. Coincidently, while roaming in the nearby swamp forest, I found an intact mature tree. The clue that lead me to the tree was the fallen fruits on the forest floor. photo photo I was not able to take any good picture of the leaves as the tree was very tall and there was no low-hanging branches.

The lone Pavetta wallichiana was bearing mature dark-green berries while at the same time having new batches of flower buds on the same plant. I did had a chance to view its full bloom flowers during my last trip here.

photo photo The most exciting moment was the sighting of these blue colour fruits hanging on a stalk which emerged from the ground. The leaves of the plant resembled those from a palm. The identity of this plant (Peliosanthes teta) was kindly provided by CK. It belongs to the lily family (Liliaceae) and not a palm after all.

Blue colour fruits are relatively rare. Another plant in the lily family with blue colour fruits is Dianella ensifolia, a commonly cultivated ornamental plant locally.

These large palm-like leaves did not catch much of my attention when I first came across them, at least not until I saw a stalk of flower originated from the base of these leaves. No doubt that it was an orchid from the typical appearance of the flowers. I had read about this orchid (Plocoglottis javanica) from an article. So, the identification part was rather straightforward.

Besides the 3 new plants documented above, I managed to find another 3 new ones to add to my collection although all 3 were presented with only leaves without fruit or flower. One is a small size palm (Pinanga simplicifrons), another one is a large-leaf tree (Myristica maxima) while the last one is a climber with trifoliate leaves (Trichosanthes elmeri).

Despite finding 6 new plants, there were another two trees with fruits which I have yet to figure out their identity. [Update: Neoscortechinia sumatrensis and Gonystylus confusus]

As usual, the forest was beaming with all kinds of tiny life forms and occasionally the mid-size ones. Highlighted below were the more interesting ones: (a) An unusually large long legged fly with orange body and blue eyes; (b) A bright green, translucent-bodied katydid known as Asiophlugis temasek, a common forest katydid that was only named recently in 2010; (c) A group of small termites and 2 Rambutan Ants (at the right side). There were at least thousands of the termites foraging or migrating within a small area.

photoWhile exiting the reservoir park, I spotted a motionless snake lying near a road kerb. Upon closer examination, it was a dead snake, probably the result from a roadkill. The body of the young Reticulated Python (Broghammerus reticulatus) looked relatively fresh and intact. The accident had probably occurred just a few hours ago.

It was kind of sad to end the trip with a dead young snake. Nevertheless, this was another of those great field trips whereby I had collected a handful of new plant pictures. There were another few more plants that presented with only leaves that I was not able to identify. Some of them were shown in the picture gallery below.
