Hibiscadelphus distans (Kauai hau kuahiwi) is an extremely rare species of flowering plant in the mallow family, Malvaceae, that is endemic to the island of Kauaʻi in Hawaii.

[2] The heart-shaped leaves are 4–10 cm (1.6–3.9 in) in length and have rounded serrations on the margins and stellate trichomes (star-shaped hairs) on the upper on lower surfaces.

[4] Associated plants include kukui (Aleurites moluccana), ʻāhinahina (Artemisia kauaiensis), alaheʻe (Psydrax odorata), lama (Diospyros sandwicensis), nehe (Lipochaeta connata), kōlea (Myrsine spp.

), kuluʻī (Nototrichium sandwicense), ʻālaʻa (Planchonella sandwicensis), Sacramento Bur (Triumfetta semitriloba) and āulu (Sapindus oahuensis).

[5] There are only two known naturally occurring populations of H. distans, both in the Lower Koaiʻe Canyon area,[2] Puʻu Ka Pele Forest Reserve,[3] with an estimated 20 wild and 150 reintroduced trees.
