Overview

Amyema spp. is a genus of roughly 90 to 100 species of aerial-stem hemiparasitic mistletoes in the family Loranthaceae, centred on Australia and extending through Malesia, Southeast Asia, and the western Pacific. Each plant grows on the branches of a host tree or shrub, attached by a haustorium that taps the host water and mineral supply while the mistletoe green leaves carry out photosynthesis. Stems are woody and pendent or spreading, forming clumps 1-7 ft (0.3-2 m) across. Leaves are usually opposite, leathery, and entire, 1-6 in (2.5-15 cm) long, and in several species closely resemble the foliage of the host. Tubular flowers 0.4-1.6 in (1-4 cm) long appear in stalked clusters and range from red and orange to yellow and green; they hold abundant nectar and are pollinated by honeyeaters and other birds. The fruit is a single-seeded berry with sticky flesh, spread when mistletoebirds wipe or excrete the seed onto a new branch. Heavy infestations can reduce the vigour of host trees and, over time, contribute to limb dieback. A. miquelii and A. pendula are widespread Australian examples.

Native Range

Amyema spp. is native to Australia, where the genus is most diverse, and ranges north and east through New Guinea, Malesia, parts of Southeast Asia, and islands of the western Pacific.

Suggested Uses

Amyema spp. is important in native ecosystems as a nectar source for honeyeaters and a fruit source for mistletoebirds, and several species are larval hosts for jewel butterflies. The genus features in studies of parasitism and woodland bird ecology rather than in cultivation.

How to Identify

Look for Amyema spp. as a clump of woody, often pendent stems growing directly from a branch of a host tree rather than from the ground. The opposite leathery leaves 1-6 in (2.5-15 cm) long sometimes mimic the host foliage, while the stalked clusters of tubular red, orange, yellow, or green flowers and the swollen haustorial attachment point identify the genus. The sticky single-seeded berries further separate Amyema spp. from non-parasitic shrubs.

Bloom Information

Flowering time varies across the genus and its wide range, with many Australian species flowering from late spring through autumn (roughly October-April in the Southern Hemisphere). The tubular nectar-rich flowers open in stalked clusters and are followed by berries over several weeks to months. In tropical species, flowering and fruiting can occur through much of the year.

Care & Maintenance

Care Guide

As obligate hemiparasites, Amyema spp. species cannot be grown in soil or containers and depend entirely on a living woody host for water and minerals. Establishment occurs naturally when a bird deposits a seed onto a suitable host branch, where the seedling forms a haustorial attachment. Host range varies by species, from eucalypts and acacias to casuarinas and mangroves. Light levels in the host canopy, host health, and bird activity for pollination and seed dispersal govern where the genus persists. Heavy mistletoe loads can stress drought-affected hosts. The genus is studied in plant ecology rather than maintained in horticulture.

Pruning

Garden pruning does not apply to these branch-dwelling parasites. In managed landscapes, infested host limbs are sometimes removed to limit mistletoe spread, which also eliminates the attached plant. Natural stem loss occurs when a host branch dies and falls.
