Ficus macrophylla, commonly known as the Moreton Bay fig or Australian banyan, is a large evergreen banyan tree of the mulberry and fig family Moraceae. It is native to eastern Australia, from the Wide Bay–Burnett region of Queensland in the north to the Illawarra region of New South Wales. The infraspecies Ficus macrophylla f. columnaris is endemic to Lord Howe Island. Its common name refers to Moreton Bay in Queensland. It is best known for its imposing buttress roots.

Ficus macrophylla is called a strangler fig because seed germination usually takes place in the canopy of a host tree, where the seedling lives as an epiphyte until its roots establish contact with the ground, when it enlarges and strangles its host, eventually becoming a freestanding tree by itself. Individuals may reach {{convert|60|m|ft|abbr=on}} in height, with crown spreads as great as {{convert|250|ft|m|abbr=off}} being reported. The greatest exact height to be reported is {{convert|232|ft|m|abbr=off|sp=us}}.{{ cite book | last= Condit | first= Ira | date= | title= Ficus - The Exotic Species | location= Davis, California | publisher= University of California Press |pages= 124–125}} It has an obligate mutualism with fig wasps; figs are pollinated only by fig wasps, and fig wasps can reproduce only in fig flowers. The wasp partner of the Moreton Bay Fig is Pleistodontes froggattii. Many species of birds, including pigeons, parrots, and various passerines, eat the fruit.

Ficus macrophylla is widely used as a feature tree in public parks and gardens in warmer climates such as California, Spain, Portugal, Italy, Malta, northern New Zealand (Auckland), and Australia. Old specimens can reach tremendous size, and their aggressive root system renders them unsuitable for all but the largest private gardens.

The leaves and branches bleed a milky sap if cut or broken. The figs are {{convert|2|–|2.5|cm|in|abbr=on|sigfig=1}} in diameter, turning from green to purple with lighter spots as they ripen; ripe fruit may be found year-round, although they are more abundant from February to May. It is a rainforest plant and in this environment more often grows in the form of an epiphytic strangler vine than that of a tree. When its seeds land in the branch of a host tree it sends aerial, "strangler" roots down the host trunk, eventually killing the host and standing alone. It is monoecious: each tree bears functional male and female flowers. As indicated by its specific epithet, it has large, elliptic, leathery, dark green leaves, {{convert|15|-|30|cm|in|round=0.5|abbr=on}} long, and they are arranged alternately on the stems. The fruit is known as a syconium, an inverted inflorescence with the flowers lining an internal cavity.

In the early 19th century, Italian botanist Vincenzo Tineo of the Orto botanico di Palermo in Sicily obtained a plant from a French nursery that grew to a prodigious size with a banyan habit. This form was propagated and grown in gardens around Sicily. A later director of the gardens, Antonino Borzì, described it as Ficus magnolioides in 1897, distinguishing it from F. macrophylla on account of its larger leaves with greener undersides. This name was widely used in Europe.{{cite journal | journal=Curtis's Botanical Magazine | title= On the real identity of Ficus magnolioides | first1=Silvio | last1=Fici | first2=Francesco Maria | last2=Raimondo | volume=13|issue=2 | year=1996 | pages =105–07 | doi= 10.1111/j.1467-8748.1996.tb00549.x}}

Australian botanist Charles Moore described Ficus columnaris in 1870 from material collected from Lord Howe Island, choosing the species name from the Latin columnaris for the column-like roots.{{cite journal | url=https://biodiversitylibrary.org/page/27155563 | journal = Transactions and Proceedings of the Botanical Society of Edinburgh|first=Charles | last= Moore | year=1870 | volume= 10 | issue = 1–4| pages= 365–71 | title= Sketch of the botany of Lord Howe's Island | doi = 10.1080/03746607009468716}} English botanist E. J. H. Corner reduced this to synonymy with F. macrophylla in 1965, before P. S. Green noted it was distinct enough for subspecies status in 1986. Australian botanist Dale J. Dixon reviewed material and felt the differences too minor to warrant subspecific status, and recognised two forms: Ficus macrophylla f. macrophylla, a free-standing tree endemic to mainland Australia; and Ficus macrophylla f. columnaris, a hemiepiphyte lacking a distinct main trunk and endemic to Lord Howe Island.{{cite journal|last=Dixon |first=Dale J. |year=2003 |title=A taxonomic revision of the Australian Ficus species in the section Malvanthera (Ficus subg.

The species is commonly known as the Moreton Bay fig, after Moreton Bay in southern Queensland, although it is found elsewhere. An alternate name—black fig—is derived from the dark colour of the ageing bark.{{cite book |title=Rainforest to Bonsai |last=Webber |first=Len |year=1991 |publisher=Simon and Schuster |location=East Roseville, New South Wales |isbn=978-0-7318-0237-1 |page=105}}

In 2005, Dutch botanist Cornelis Berg completed Corner's treatment of the Moraceae for the Flora Malesiana; the completion of that work had been delayed since 1972 as a result of disagreements between Corner and C. J. J. G. van Steenis, editor of the Flora Malesiana.{{cite journal | last1 = Weiblen | first1 = G. D. |first2=W. L. |last2= Clement | year = 2007 | title = Flora Malesiana. Series I.

This left the Moreton Bay fig in subsection Malvanthera, section Stilpnophyllum.

In a 2008 study on DNA sequences from the nuclear ribosomal internal and external transcribed spacers, Danish botanist Nina Rønsted and colleagues rejected previous subdivisions of the Malvanthera. Instead, they divided section Malvanthera into three subsections—Malvantherae, Platypodeae, and Hesperidiiformes. In this system, the Moreton Bay fig is in the subsection Malvantherae, along with F. pleurocarpa. The Malvantherae appear to be basal (an early offshoot) to the group. F. macrophylla form macrophylla is native to mainland Australia, while form columnaris of macrophylla colonised Lord Howe Island. The section Malvanthera itself is thought to have evolved 41 million years ago and radiated around 35 million years ago.

The thrips species Gynaikothrips australis feeds on the underside of new leaves of F. macrophylla, as well as those of F. rubiginosa and F. obliqua.

Stressed trees can also be attacked by psyllids to the point of defoliation. Grubs hatch from eggs laid on the edges of leaves and burrow into the leaf to suck nutrients, the tree's latex shielding the insect. Caterpillars of the moth species Lactura caminaea (Lacturidae) can strip trees of their leaves. The tree is also a host for the longhorn beetle (Cerambycidae) species Agrianome spinicollis. The fungal pathogen brown root rot (Phellinus noxius) has infected and killed this species.{{cite web | url=http://www.northerntreecare.com.au/wp-content/uploads/2017/10/Brown-Root-Rot.pdf | title=Brown Root Rot | first=Peter | last=Gray | date=2017 | access-date=20 April 2018 | archive-date=17 March 2018 | archive-url=https://web.archive.org/web/20180317161005/http://www.northerntreecare.com.au/wp-content/uploads/2017/10/Brown-Root-Rot.pdf | url-status=dead }}

=Reproduction and life span=

File:Pleistodontes froggatti female.jpg, the fig wasp that pollinates the Moreton Bay fig]]

Figs have an obligate mutualism with fig wasps (Agaonidae); figs are pollinated only by fig wasps, and fig wasps can reproduce only in fig flowers. Generally, each fig species depends on a single species of wasp for pollination. The wasps are similarly dependent on their fig species to reproduce. The mainland and Lord Howe populations of the Moreton Bay fig are both pollinated by Pleistodontes froggatti.{{cite journal | last = Lopez-Vaamonde | first = Carlos |author2=Dale J.

As is the case with all figs, the fruit is an inverted inflorescence known as a syconium, with tiny flowers arising from the inner surface. Ficus macrophylla is monoecious—both male and female flowers are found on the same plant, and, in fact, in the same fruit, although they mature at different times. Female wasps enter the syconium and lay eggs in the female flowers as they mature. These eggs later hatch and the progeny mate. The females of the new generation collect pollen from the male flowers, which have matured by this point, and leave to visit other syconia and repeat the process. A field study in Brisbane found that F. macrophylla trees often bore both male and female syconia at the same time—which could be beneficial for reproduction in small, isolated populations such as those on islands. The same study found that male phase syconia development persisted through the winter, showing that its wasp pollinator tolerated cooler weather than those of more tropical fig species. F. macrophylla itself can endure cooler climates than other fig species.{{Cite journal | last1 = McPherson | first1 = John R. | title = Phenology of Six Ficus L., Moraceae, Species and its Effects on Pollinator Survival, in Brisbane, Queensland, Australia | doi = 10.1111/j.1745-5871.2005.00329.x | journal = Geographical Research | volume = 43 | issue = 3 | pages = 297–305 | year = 2005 }} Moreton Bay fig trees live for over 100 years in the wild.

=Potentially invasive species=

File:MoretonBayNaturalisedNZ.jpg, New Zealand, park]]

Ficus macrophylla is commonly cultivated in Hawaii and northern New Zealand. In both places, it has now naturalised, having acquired its pollinating wasp (Pleistodontes froggatti). In Hawaii, the wasp was deliberately introduced in 1921, and in New Zealand it was first recorded in 1993, having arrived by long-distance dispersal from Australia. The arrival of the wasp led to prolific production of fruits containing many small seeds adapted for dispersal by birds. The Moreton Bay fig has been found growing on both native and introduced trees in New Zealand and Hawaii. The size and vigour of this fig in New Zealand, and its lack of natural enemies, as well as its immunity to possum browsing, indicate that it may be able to invade forest and other native plant communities.{{cite journal | last = Gardner | first = Rhys O. | author2 = John W.

Cultivation

The Moreton Bay fig has been widely used in public parks in frost-free areas, and was popular with early settlers of Australia. Around the beginning of the 20th century, the director of the Royal Botanic Gardens in Sydney, Joseph Maiden, advocated the planting of street trees, generally uniform rows of the one species. He recommended Moreton Bay figs be spaced at {{convert|30|m|ft|abbr=on|sigfig=1}} intervals—far enough to avoid crowding as the trees matured, but close enough so that their branches would eventually interlock.{{cite journal|last=Frawley|first=Jodi|year=2009|title=Campaigning for Street Trees, Sydney Botanic Gardens 1890s–1920s|journal=Environment and History|volume=15 |issue=3 |pages=303–22 |url=http://www.environmentandsociety.org/sites/default/files/key_docs/frawley-15-3.pdf |doi=10.3197/096734009x12474738199953}} Specimens can reach massive proportions, and have thrived in drier climates; impressive specimen trees have been grown in the Waring Gardens in Deniliquin, and Hay.{{cite book |title=Australian Trees for Australian Planting |last=de Beuzeville | first= W.A.W. |year=1947 |publisher=Forestry Commission of New South Wales/ A.

However, their huge size precludes use in all but the largest gardens, and their roots are highly invasive and can damage piping and disrupt footpaths and roadways; the vast quantities of crushed fruit can be messy on the ground.

Especially due to their tendency for root buttressing, they are frequently seen as bonsai, although they are much more suited to larger styles as their large leaves do not reduce much in size and their stems have long intervals (internodal spaces) between successive leaves.{{cite book |title=Bonsai with Australian native Plants |author=Koreshoff, Dorothy and Vita |year=1984 |publisher=Boolarong Publications |location=Brisbane, Queensland |isbn=978-0-908175-66-6 |page=52}} It can be used as an indoor plant in medium to brightly lit indoor spaces.{{cite book |title=Australian Native Plants for Indoors |last=Ratcliffe |first=David and Patricia|year=1987 |publisher=Little Hills Press |location=Crows Nest, New South Wales|isbn=978-0-949773-49-4 |page= 90}}

=Notable specimens=

Large specimens of Moreton Bay fig trees are found in many parks and properties throughout eastern and northeastern Australia. The Brisbane, Melbourne, and Sydney botanic gardens contain numerous specimens planted in the middle of the 19th century, which are up to {{convert|35|m|ft|abbr=out}} tall. At Mount Keira, near Wollongong there is a Moreton Bay fig measured at {{convert|58|m|ft}} tall.{{cite web|title=Moreton Bay Fig – Mount Keira|url=http://www.nationalregisterofbigtrees.com.au/listing_view.php?listing_id=397|work=National Tree Register of Big Trees|access-date=23 November 2011}} A notable tree in the Sydney suburb of Randwick, the 150-year-old "Tree of Knowledge", was controversially cut down in 2016 to make way for the CBD and South East Light Rail.{{cite news | url=https://www.theguardian.com/australia-news/2016/jul/11/historic-moreton-bay-fig-being-felled-to-make-way-for-sydney-light-rail | title=Historic Moreton Bay fig being felled to make way for Sydney light rail | date =11 July 2016 | access-date=3 April 2018 | work=The Guardian}} There are many large specimens in New Zealand.

Uses

The soft light timber has a wavy texture and is used for cases. Aboriginal people traditionally use the fibres for fishing nets. The fruits are edible and taste like other fig varieties.{{Citation |title=Native Nibbles |date=2017-05-13 |url=https://www.abc.net.au/gardening/factsheets/native-nibbles/9440302 |publisher=Australian Broadcasting Corporation |language=en-AU |access-date=2022-06-16}}
