The Northern Territory form of Drosera paradoxa is found in sandstone creeks in the Arnhem Escarpment. It is known for its towering stems.

Drosera paradoxa NT-form is a medium sized sundew that grows 10-30 cm tall. Arching leaves with round laminae and thin, hairy petioles are formed along an elongated stem. Feathery stipules line the stem. The leaves are replaced relatively quickly, with the newest leaves forming a rosette up to around 8 cm in diameter. The flower scapes are very hairy.

The species is known from sandstone substrates in the Arnhem Escarpment and Kakadu National Park, where it is associated with creeks atop waterfalls. It also grows in nearby seepages and soaks atop sandstone. The creekside habitat periodically floods during the wet season. Plants are able to persist in this habitat with their strong roots that cling onto the sandstone. They tend to grow amongst grassy patches, which provide some shelter from the floods. The species is able to grow perennially, although a large proportion of plants appear to germinate, mature and die within one season.

Drosera paradoxa NT-form is distinguished from all other sundews within its range by its long, upright stems and rosettes with many leaves. It bears a tangential resemblance to D. banksii but is a much larger plant (D. banksii is typically very small and has sparse leaves). There are other localities of Drosera paradoxa from Western Australia that share a similar morphology and habitat, but their relationship is poorly understood.
