OVERVIEW

Ochna species are ornamental shrubs and tress native to tropical woodlands of Africa and Asia. Several species, including Ochna thomasiana, are cultivated in Hawai'i for their colorful flowers and unusual fruits. On Maui, Ochna species are commonly seen in gardens as specimen plants or as hedges in residential and urban areas. During roadside surveys on Maui in 2000, it was found that Ochna spp. were particularly popular and widely planted and naturalized in a few lowland residential areas, including Lahaina, Wailuku, and Kahului. Ochna species were less commonly observed in Kapalua, Ha'iku, Pukalani, Kula, and Kipahulu. During these surveys, plants were only identified to genus level, so it is uncertain whether the majority of these were O. serrulata or O. thomasiana or a combination of both. On Maui, O. thomasiana is naturalized on both West and East Maui (Oppenheimer 2003, in press, Starr et al. 2003, in press). O. serrulata is naturalized on the island of Hawai'i at Manuka, but has not yet been documented as naturalized on Maui and perhaps is the less commonly planted of the two species on Maui, though this is not certain. Regardless, in Hawai'i both species are known to spread from initial plantings via bird dispersed fruits, frequently volunteering near homes and gardens and nearby disturbed areas. On East Maui, a few mature trees along with numerous small seedlings that were scattered within 4 m (12 ft) of parent plants of Ochna thomasiana were recently discovered by Park staff in a disturbed mesic lowland forest in the Ka'apahu district of Haleakala National Park. No other plants were observed nearby.

While Ochna spp. are fairly widespread in cultivation on Maui, they are not common in natural areas yet. Early detection and rapid control of discrete incipient populations in and near protected natural areas may help prevent future infestations of Ochna spp. in sensitive areas.

TAXONOMY

Family: Ochnaceae (Ochna family) (Herbarium Pacificum Staff 1998, Wagner et al.

1999).

Latin name: Ochna thomasiana Engl. & Gilg (Herbarium Pacificum Staff 1998,

Wagner et al. 1999).

Synonyms: Ochna kirkii D. Oliver, incorrectly identified in previous local botanical literature including Neal (1965) and Wagner et al. (1990).

Common names: Mickey Mouse plant, bird's eye bush (Brickell and Zuk 1997).

Taxonomic notes: The genus, Ochna, is made up of over 80 species of deciduous or semi-evergreen trees and shrubs from the tropical woodlands of Africa and Asia. Previously called Ochna kirkii and reidentified as O. thomasiana (Herbarium Pacificum Staff 1998, Wagner et al. 1999).

Nomenclature: The common name (Mickey Mouse plant) is derived from the large

drupelet fruits that look like mouse ears (Whistler 2000).

Related species in Hawai'i: Two species of Ochna are documented as naturalized in Hawai'i, Ochna serrulata and Ochna thomasiana. Other Ochna species that are

cultivated in Hawai'i include Ochna integerrima (Vietnamese Mickey Mouse plant) and Ochna mossambicensis (African Mickey Mouse plant).

DESCRIPTION

"Lenticellate twigs and branchlets; broadly elliptic leaf blades, more or less cordate at the base and clasping the stem; and the 5-8 prominent, long cilia on the margin of the blade in the basal half. There are up to 12 glossy black drupelets borne erect on the red, waxy receptacle with reflexed red sepals." (Herbarium Pacificum Staff 1998, Wagner et al.

1999).

"Shrub to 2 m high (6 1/2 ft) or more. Leaves simple, alternate, blade elliptic, 3-12 cm long (1 1/4-5 in), glabrous, with bristle-toothed margins. Flowers intermittently during the year; flowers several, borne in axillary and terminal clusters. Corolla of five free, obovate, yellow petals 1.8-2.5 cm long (3/4-1 in), with many yellow stamens in the center. Fruit composed of one to five black ovoid drupelets 7-10 mm long (1/4-3/8 in) borne on a fleshy red disk around the long, red style, with a red, persistent calyx."

(Whistler 2000).
