Description

The opposite[3] flat leaves have a distinct stem[6] and are thick, fleshy and round, and can be up to 6 cm in length.[3] The inflorescence is an umbel of two or more triads or tetrads (flowering in a group of four).[6] The mature buds are terete (long and cylindrical) or angular, and smooth or with just a few scattered hairs.[6]

Ecology

A. mackayensis is found along the coast and in maritime communities, on mangroves,[4] in particular on the Grey Mangrove (Avicennia marina)[3] Moss & Kendall comment that there is evidence that this mistletoe accumulates excess salt loads in leaves which it sheds, and thus reduce its salt load.[3]

Taxonomy

A. mackayensis was first described by Blakely in 1922 as Loranthus mackayensis,[7] but in 1929 was placed in the genus Amyema by Danser.[1][2]
