Sankowskya stipularis is a genus and a sole known species of trees found only (endemic) in one locality in the Wet Tropics rainforests of north eastern Queensland, Australia. The species constitutes part of the plant family Picrodendraceae. Few botanical collections have ever been made of the trees, from a very restricted area of the Wet Tropics rainforests, hence the species has obtained the conservation status of "endangered" in the legislative regulation of the Queensland Government's Nature Conservation Act 1992. Notably, trees grow naturally in the Thylogale Nature Refuge.
