'Amyema' is Greek, referring to a genus previously not known. 'mackayensis' is a reference to the type locality of Mackay, Queensland. ([1])


A mistletoe which is a parasite on many mangrove plants which elliptic (oval), fleshy leaves, flowers with 5 petals and elliptic fruit ([1]).

Botanical Description

An aerial stem parasite with an upright or spreading habit. Leaves are opposite, elliptic (oval), somewhat fleshy, 30-60 cm long and 22-45 cm wide with a rounded apex.

The inflorescence is an umbel (consisting of a number of short flower stalks) with red to yellow-green flowers, each 15-18 cm long with 5 petals.

The fruit are oval, berry-like, producing one seed ([1]).


In Australia this species occurs in Western Australia, sporadically across the coast in the Northern Territory and in Queensland. It is also found in New Guinea ([1]).

See Atlas of Living Australia


This species has been recorded growing on the following hosts in the Northern Territory: Rhizophora stylosa, Avicennia marina, Campostemon schultzii and Aegiceras corniculatum ([1]).

In other states it has also been recorded from: Lumnitzera, Excoecaria, Thespesia, Ceriops tagal, Rhizophora mucronata and several other non-mangrove plants ([1]).

Produces flowers and fruit throughout the year ([1]).

Mistletoebirds (Dicaeum hirundinaceum) are the primary distributors of this species. The seeds are expelled from the birds within 25 minutes of being eaten and the sticky residue adheres to branches of potential hosts. As the seeds germinate they grow into the host. The reddish petals attract birds as pollinators ([2], [3]).

Similar Species

Amyema mackayensis can be distinguished from Amyema thalassia by a 5-merous corolla, 3-4 rays and elliptic leaves. Amyema thalassia has a 4-merous corolla, 2 rays and orbicular-obovate leaves ([1]).
