Nepenthes tenax

Nepenthes tenax (from Latin: tenax "tenacious") is a lowland species of tropical pitcher plant native to northern Queensland, Australia. It is the third Nepenthes species recorded from the continent and its second endemic species. Nepenthes tenax is closely related to the three other Australian Nepenthes species: N. mirabilis, N. rowaniae and N. parvula.

Nepenthes tenax grows to a height of around 100 cm with pitchers rarely exceeding 15 cm. The stem is usually self-supporting. In its natural habitat, it is sympatric with N. mirabilis and N. rowaniae. Simple and complex natural hybrids involving both of these species have been found.

Distribution
Nepenthes tenax reside in the lower levels of the swamps on floodplains surrounding the Jardine River on the northern Cape York peninsula appear to be the only habitats for this species, which is reportedly restricted to open sandy substrates or saturated wetlands.
