The blurry photographs below clearly showed that I have not mastered how to take good photographs using auto point and shoot camera without flash and tripod in a dark forest... :-P The C. longicauda growing on the upper sides of the stream banks had browner leaves as compared to those growing along the bed of the stream.
Below is a shot of the habitat with flash on.
We found an unopened spathe and when I attempted to take a photograph of it, I was taken aback when the face detection frame suddenly appeared on the screen of my Canon A480 digital camera. The camera actually detected the yellow leaf with holes beside the spathe as a face!!!
The pH of the water in the stream was about 4.5 and the bed of the stream was formed by fine whitish sand.
