Ficus rubiginosa
Ficus rubiginosa, the rusty fig or Port Jackson fig (damun in the Dharug language), is a species of flowering plant native to eastern Australia in the genus Ficus. Beginning as a seedling that grows on other plants (hemiepiphyte) or rocks (lithophyte), F. rubiginosa matures into a tree 30 m (100 ft) high and nearly as wide with a yellow-brown buttressed trunk. The leaves are oval and glossy green and measure from 4 to 19.3 cm (1+1⁄2–7+1⁄2 in) long and 1.25 to 13.2 cm (1⁄2–5+1⁄4 in) wide.
The fruits are small, round, and yellow, and can ripen and turn red at any time of year, peaking in spring and summer. Like all figs, the fruit is in the form of a syconium, an inverted inflorescence with the flowers lining an internal cavity. F. rubiginosa is exclusively pollinated by the fig wasp species Pleistodontes imperialis, which may comprise four cryptospecies. The syconia are also home to another fourteen species of wasp, some of which induce galls while others parasitise the pollinator wasps and at least two species of nematode. Many species of bird, including pigeons, parrots, and various passerines, eat the fruit. Ranging along the Australian east coast from Queensland to Bega in southern New South Wales (including the Port Jackson area, leading to its alternative name), F. rubiginosa grows in rainforest margins and rocky outcrops. It is used as a shade tree in parks and public spaces, and when potted is well-suited for use as an indoor plant or in bonsai.
Ficus rubiginosa was described by French botanist René Louiche Desfontaines in 1804, from a type specimen whose locality is documented simply as "New Holland". In searching for the type specimen, Australian botanist Dale Dixon found one from the herbarium of Desfontaines at Florence Herbarium and one from the herbarium of Étienne Pierre Ventenat at Geneva. As Ventenat had used Desfontaines' name, Dixon selected the Florence specimen to be the type in 2001. The specific epithet rubiginosa related to the rusty coloration of the undersides of the leaves. Indeed, rusty fig is an alternate common name; others include Illawarra fig and Port Jackson fig. It was known as damun (pron. "tam-mun") to the Eora and Darug inhabitants of the Sydney basin.
In 1806, German botanist Carl Ludwig Willdenow gave it the botanical name Ficus australis in Species Plantarum, but this is a nomen illegitimum as the species already had a validly published name. Italian botanist Guglielmo Gasparrini broke up the genus Ficus in 1844, placing the species in the genus Urostigma as U. rubiginosum. In 1862, Dutch botanist Friedrich Anton Wilhelm Miquel described Urostigma leichhardtii from material collected from Cape Cleveland, Queensland, noting it had affinities to F. rubiginosa. In 1867, he placed Urostigma as a subgenus in the reunited Ficus, which resulted in the taxon becoming Ficus leichhardtii. Miquel also described Ficus leichhardtii variety angustata from Whitsunday Island, later classified as F. shirleyana by Czech botanist Karel Domin. Queensland state botanist Frederick Manson Bailey described Ficus macrophylla variety pubescens in 1911 from Queensland, Domin later renaming it Ficus baileyana. All these taxa were found to be indistinguishable from (and hence reclassified as) F. rubiginosa by Dixon in 2001.
In a study published in 2008, Nina Rønsted and colleagues analysed the DNA sequences from the nuclear ribosomal internal and external transcribed spacers, and the glyceraldehyde 3-phosphate dehydrogenase region, in the first molecular analysis of the section Malvanthera. They found F. rubiginosa to be most closely related to the rainforest species F. watkinsiana and two rock-growing (lithophytic) species of arid northern Australia (F. atricha and F. brachypoda). They classified these species in a new series Rubiginosae in the subsection Platypodeae. Relationships are unclear and it is uncertain into which direction the group radiated (into rainforest or into arid Australia).
Joseph Maiden described variety lucida in 1902, and Bailey described variety glabrescens in 1913. Both had diagnosed their varieties on the basis of their hairlessness. Maiden described a taxon totally devoid of hair, while Bailey described his as nearly glabrous (hairless). As Bailey's description more closely matched Dixon's findings (that these variants were only partly and not completely hairless), Dixon retained Bailey's name and reclassified it as Ficus rubiginosa forma glabrescens in 2001 as it differed only in the lack of hairs on new growth from the nominate form.
A spreading, densely-shading tree when mature, F. rubiginosa may reach 30 m (100 ft) or more in height, although it rarely exceeds 10 m (30 ft) in the Sydney region.
The trunk is buttressed and can reach 1.5 m (4 ft 11 in) in diameter. The bark is yellow-brown. It can also grow as on other plants as a hemiepiphyte, or 1–5 m (3–16 ft) high lithophyte.
