The nutrients-poor soil of the kerangas and peat swamp forest have driven many plants to supplement their autotrophic existence by other nutritional means. Borneo has an astonishing variety of such plants - as I discovered during a day trip at a kerangas bordering a peat swamp forest .
Under the full glare of the sun and on persistantly wet sandy area, the sundew Drosera burmanii coexist with a population of bladderwoth Utricularia - which would almost be unnoticeable were it not for the yellow bloom.
The tentatcles of the Drosera burmanii are tactile and produce both a sweet fluid and a sticky glue - these attracts insects from which they then surround and entrap. The speed of movement of the tentalces in this species is one of the fastest in the genus - closing in on the prey between 5-10 seconds.
The dimunitive nature of these plants mean that they easily be outcompete by larger, faster growing plants in richer soils so they are restricted in bright, acidic and nutrient-poor area
The pitcher plant genus Nepenthes has the most diversity in Borneo and Philippines. Unlike the previous species, Nepenthes do not have movable parts to ensnare their prey. One of the largest lowland species Nepenthes rafflesiana shown below- demonstrate its usual modus operandi - trapping, drowning and assimilating invertebrates in its large pitchers. Note the large lid sheltering the pitcher in this photo - it serves to prevent dilution of the digestive enzymes from rain water.
This species was actually first discovered in Singapore by Dr William Jack in 1819.
Nepenthes ampullaria, on the other hand, has a tiny lid, which flips away from from the pitcher opening. This species does not catch much insects - instead it relies on leaf debris and other organic waste dropping into the pitchers and so it clearly wants the lid out of the way. Its pitchers also do not have slippery inner wall and very little nectar gland which produce insect attractants....
The Borneo endemic Nepenthes bicalcarata has a pair of downward facing fangs growing from the the pitcher peristome. The function of this is still a matter of debate. Although it feeds on the carpenter ants that nests in its tendrils, it also benefits from a symbiotic way since the ants are shown to provide housekeeping service by removing excess undigested organic material, thereby preventing bacterial / fungal proliferation and early demise of the pitchers.
The pitchers are medium size and the red variety is quite horticultural.
There are 2 forms - the lowland green form .....
and the attractive dark form from higher elevation.
Nepenthes mirabilis is one of the most widely distributed species and the normal form has rather unremarkable attributes although the variety echinostoma, which I could not find, has surreal and weird peristome. In my previous post I had found pitchers filled with ants.
The pictures below look very much like the lower pitchers of N. rafflesiana but I think it is the hybrid with N. ampullaria known as Nepenthes xhookeriana
This is another hybrid, I believe Nepenthes rafflesiana x mirabilis and it appears that one of the parent is very red. Natural hybrid is very common amongst Nepenthes particularly in high diversity area like Borneo where the different species co-exist in the same area.
The tree itself was tall and errect so it was quite unusual to have this tangled mess of stilt roots growing from only one side, dangling in the air. 
I cannot explain its unnusual growth habit but I did manage to find its name from a friend - who coincidentally, volunteered in an organisation called 
The fruit capsule :
I chanced upon a Malayan brown snake Xenelaphis hexagonotus while out hiking at night. This non venonmous creature was in the forest stream noisily foraging for snacks, most likely young frogs. Suddenly, a young water monitor dashed out from nowhere and pursued it until both disappeared into the darkness....it happened so quickly I had no time to shoot.
This is an unknown plant, possibly a young Pandan or an unusual palm. If you have any suggestions, please let me know.
Piptospatha ridleyii, an endemic rheophyte from Peninsula Malaysia growing on mossy rocks at a trickling stream.
Moss covered trunk and bracket fungus. Humidity is very high here, and the air is stale and still. 
Asplenium phyllitidis is another bird nest fern similar to A. nidus but has narrower leaves. It also inhibits lower and more humid place while A. nidus can be seen in open and dry places, including high up at roadside tree.
This is the jungle version of our table pepper - Piper porphoryphyllum aff, is a humidity loving plant quite often seen in the Malaysian forest. It may be seen creeping along the undergrowth until it finds a good support from which it continue its growh upwards as shown. It is not an easy plant to grow in a normal garden although it is very ornamental. It will quickly succumb to even short periods of low humidity.
Henckelia puncticulata is found only on steep banks around SE Johore area. Although locally common, globally it is very vulnerable to extinction as its habitat is not protected and subjected to haphazard and ill-planned developments. Where we found it, the plants are forming a vertical carpet covering a steep bank near the river. A bulldozer was noisily doing its damage just across the river as we took photos. 
This Asian relative of the African violet does look like its famous cousin, albeit with variegated leaves. I think it should have a place in horticulture. 
Beside a small forest stream, stained dark brown by logging up stream, a solitary Tacca integrfolia (Bat Lily) quietly bloomed. 
The family Taccaceae is a small family of about 10 monocots from SE Asia and Africa. Recently, taxonomists lump the group together with the true yam family Dioscoreaceae.
I may need this, my handphone is not getting any signal. 
A little moth baby (Lyssa menoetius *). 
I'm sure your parents will be so proud !
Nepenthes gracilis is a widespread and common pitcher plant from SE Asia. Its latin name describes the long slender leaves characteristic of this species. The normal colour of the pitcher is green, sometimes spotted red but at this open shrubby grassland beside the peat forest, we saw a population with completely red pitchers,almost totally covered by club moss and dried leaves..
