Abutilon menziesii is a beautiful shrub with velvety light green, heart shaped leaves. Its flowers range from pale pink to maroon and are borne singularly at the base of the leaves. Abutilon menziesii has apparently been uncommon since its discovery in the 1800's, and is currently found in the dry forests of Lana`i, East Maui and Hawai`i. In 1981, a specimen collection was made in an abandoned cane field at Ewa, on the island of Oah`u and identified as Abutilon menziesii. It was thought at the time to be an escape from cultivation, but today plants located at the Ewa location are recognized as a distinct, naturally occurring population.

Endemic to the islands of Oahu, Maui, Lanai, and Hawaii, this species numbers fewer than 500 plants. Throughout the Hawaiian Islands, the species' low elevation dry habitat has been destroyed or altered by agriculture, urban development, alien plants and animals, and fire.
