Site Species Images Description
Lambir N.bicalcarata Found this species near the pond, where it was shady. Those in the direct sunlight were not as lively as those in the shade. It was also planted in the flower garden. It has two hooks under the lid which are sais to be the nectar glands. I observed small droplets on the nectary glands and an ant was at the tip of one of this.
Lambir N.ampularia This species has mostly ground pitchers. It is different from the ones I saw as it was stocky and broad. Instead of insects, they had detritus in them. The lid did not cover the pitcher like the others did. This clump of pitchers was in a damp area under a clump of tall grass in a shady area. Another clump of this species was on the slope in the grassy area on clay soil on the side of the road.
Lambir N.gracilis I found this species growing along the roadside in short grass. It spreads itself in the grass to trap as many insects as possible. There were lots of terrestrial pitchers (with wings). This species is small compared to the N. bicalcarata.
Lambir N.mirabilis notes
Kota Kinabalu N.xkinabaluensis This is a hybrid between the N. rajah and N. villosa. It grows in the ultramafic soil at 4.5km along the Gunung Kinabalu trail. It was growing among the stunted Leptospermum. There were lots of the plants in that ultramafic area. For size it fitted into the palm but my hand did not fully close around it.
Kota Kinabalu N.villosa This species was growing along the Gunung Kinabalu trail at 2700m in mossy area and also abundant under the Leptospermum trees.
Kota kinabalu N.tentaculata This species was abundant starting at 1000m along the trail. The main distinguishing feature was the hairs on the lid. The terrestrial pitchers were different from their aerial friends in color especially. The ground ones were darker, (red and green) while the upper pitchers were light green.
