Muellerina eucalyptoides, commonly known as creeping mistletoe,Watson, D. M. (2011). Mistletoes of Southern Australia. Collingwood, Victoria: CSIRO Publishing. is a hemiparasitic aerial shrub in the family Loranthaceae. The species is endemic to Australia.
Taxonomy Muellerina is a member of Santalales, the mistletoe order, placed within the family Loranthaceae. The name Muellerina was first published by Philippe Édouard Léon Van Tieghem in 1895,Tieghem, P.E.L. van (1895) Bulletin de la Société Botanique de France 42: 25, 85, 175 where one New Zealand species, Muellerina raoullii, and two Australian species (Muellerina celastroides and M. eucalyptifolia - now M. eucalyptoides) are given.van Tieghem, P. E. L. (1895). "Sur Les Loranthoidées De La Nouvelle-Zélande." Bulletin de la Société Botanique de France 42(1): 23-30 Further Australian Muellerina species are listed in van Tieghem.van Tieghem, P. E. L. (1895). "Sur Les Loranthoidées D' Australie." Bulletin de la Société Botanique de France 42(2): 82-88 Another article by van Tieghem further discussing the relationships of Loranthaceae genera is van Tieghem.van Tieghem, P. E. L. (1895).

Bulletin de la Société Botanique de France 42(2): 161-180 Muellerina eucalyptoides was first described as Loranthus eucalyptoides by de Candolle in 1830,de Candolle, A.P.(1830), Loranthaceae. Prodromus Systematis Naturalis Regni Vegetabilis 4: 318 and revised in 1962 to Muellerina eucalyptoides by BarlowBarlow, B.A. (1962), Studies in Australian Loranthaceae. I.

Description M. eucalyptoides is pendulous in habit, unlike other Muellerina species, but has the long epicortical runners of all Muellerina species.
The leaves are opposite with indistinct venation. Mainly flowering in summer, the inflorescence is terminal, racemose with usually 3–4 opposite pairs of triads of flowers, with the central flower sessile, and the lateral flowers having pedicels. Corolla curved in bud, free, 5-merous. Stamens are unequal, with anthers dorsifixed and versatile. The fruit is pear-shaped.
Propagation in Melbourne street trees
In 2017, as part of an experimental effort to increase biodiversity in Melbourne street trees, over 800 seeds of M. eucalyptoides were attached to London plane (Platanus × hispanica) trees in the Melbourne urban area. Researchers have stated that:
M. eucalyptoides was chosen for the experiment because it grows on non-native host species, whereas many other Australian mistletoes are host-specific.
A follow-up survey found 24 live seedlings - a success rate of around 3% that is considered good for propagation of mistletoe.
