Linii is an extremely rare species from Bako national park in Sarawak. It grows only on three islands a few hundreds meter from the sea, on top of the hills, along with nepenthes ampullaria. It is very dry, and extremely sunny where they grow. I went there in 2004. Only one official guide from the Bako park knows where it grows. It has been a shock as well to see nepenthes growing in dry clay, full sun, and low humidity. There were ampullaria, rafflesiana, and apparently several hybrids colonies between the two. A lot of hydnophytum on the trees as well.
That picture would be more of a tortipetalum type in fact. Linii has as well extremely narrow leaves, about 1cm x 15 cm, a bit thick, mottled dark green on a grey background.
