Abutilon eremitopetalum is a shrub in the mallow family (Malvaceae) and endemic to the island of Lanai. Leaves are grayish-green, densely hairy, heart-shaped leaves 7 to 12 cm (2.5 to 5 in) long. One or two flowers on stems up to 4 cm (1.5 in) long are in the leaf axils. The calyx of the flowers is green, cup-shaped, and about 1.5 cm (0.5 in) long. The petals are shorter than the calyx and are bright green on the upper surface and reddish on the lower surface. The staminal column extends beyond the calyx and is white to yellow, with red style branches tipped with green stigmas. The fruit is a hairy, brown, dry, cylindrical capsule and about 1 cm (0.3 in) long. It is the only Abutilon on Lanai whose flowers have green petals hidden within the calyx.
