Nepenthes × trusmadiensis (after Mount Trus Madi) is a natural hybrid of two famous Bornean pitcher plant species: N. lowii and N. macrophylla. N. × trusmadiensis is restricted to Mount Trus Madi, where both of its parent species are sympatric.[1]
N. × trusmadiensis was first discovered by Johannes Marabini and John Briggs in 1983. It was described the same year by Marabini.[2] Briggs wrote the following account of its discovery:[3][4]
We were about to leave the summit around 8.00 a.m. when Johannes Marabini emerged from a dense bush [...] holding two huge pitchers quite unlike any other species. The most striking feature was the sheer size of the pitchers—they were bigger than anything else on Trus Madi. Later on, we were to realise that they were the second biggest pitchers of all the Borneo Nepenthes—exceeded only by those of N. rajah on Kinabalu. [...] The evidence strongly suggested the new pitcher-plant was a hybrid of N. lowii and N. edwardsiana. The great size of the pitchers agreed with this idea—being characteristic of hybrids. There was no time to investigate the distribution of this new plant. So, after collecting a few specimens we set off down the mountain for the three-day trek back to Tambunan.
