Description
  • Global Rank: G1 - Critically Imperiled
  • Legal Status: Federally Endangered
  • Family: Malvaceae
  • State: HI
  • Nature Serve ID: 129364
  • Date Inducted in National Collection: 02/10/1987

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.

Ecological Relationships

Carpenter bees and honey bees have been observed on the flowers, although honey bees seem to have difficulty accessing nectar because of the small size of the flowers. The native bee Nesoprosopis has rarely been observed on flowers of this species, and may have been more important as a pollinator in the past. Seed dispersal agents, longevity of plants and seeds, specific environmental requirements, and other limiting factors are unknown. (USFWS 1995)
