Eucalyptus is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of Eucalyptus are trees, often mallees and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, the leaves have oil glands, and the sepals and petals are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Eucalyptus pauciflora, commonly known as snow gum, cabbage gum or white sally, is a species of tree or mallee that is native to eastern Australia. It has smooth bark, lance-shaped to elliptical leaves, flower buds in clusters of between seven and fifteen, white flowers and cup-shaped, conical or hemispherical fruit. It is widespread and locally common in woodland in cold sites above 700 m (2,300 ft) altitude.
Eucalyptus haemastoma, commonly known as scribbly gum, is a species of tree that is endemic to the Sydney region. It has white or silvery grey bark, lance-shaped or curved adult leaves, flower buds in groups of between nine and fifteen, white flowers and conical or hemispherical fruit. It is one of several eucalypts with prominent and differing insect scribbles in the bark, caused by the larvae of Ogmograptis,.
Eumeta crameri is a bagworm moth of the family Psychidae. It was described by John O. Westwood in 1854 and has worldwide distribution in tropical and subtropical habitats, including India, Bangladesh, Sri Lanka, New Zealand and Puerto Rico.
White gum is a common name of a great many Eucalyptus species, all of which have smooth white bark.
Scribbly gum is a name given to a variety of different Australian Eucalyptus trees which play host to the larvae of scribbly gum moths which leave distinctive scribbly burrowing patterns on the bark.
Xanadoses is a monotypic moth genus in the family Cecidosidae. It contains a single species, Xanadoses nielseni, which is endemic to New Zealand. X. nielseni is also known by the common name Kamahi bark scribbler. The larval host of this species is Weinmannia racemosa.
Eucalyptus rossii, commonly known as inland scribbly gum or white gum, is a species of small to medium-sized tree that is endemic to New South Wales and the Australian Capital Territory. It has smooth bark with insect scribbles, lance-shaped adult leaves, flower buds in groups of between nine and fifteen, white flowers and hemispherical or shortened spherical fruit.
Psaltoda moerens, commonly known as the redeye, is an Australian species of cicada. It is distributed through the south-east of Australia, from southern Queensland to South Australia, as well as Tasmania. Populations can vary greatly between years; one year they may be present in large numbers and the next they may be entirely absent. They feed primarily on eucalyptus but also on Angophora trees. As they feed on tree sap they expel small droplets of clear waste fluid. When numbers are high, this can form a constant stream.
Corymbia eximia, commonly known as yellow bloodwood, is a bloodwood native to New South Wales. It occurs around the Sydney Basin often in high rainfall areas on shallow sandstone soils on plateaux or escarpments, in fire prone areas. Growing as a gnarled tree to 20 m (66 ft), it is recognisable by its distinctive yellow-brown tessellated bark. The greyish green leaves are thick and veiny, and lanceolate spear- or sickle-shaped. The cream flowerheads grow in panicles in groups of seven and appear in spring. Known for many years as Eucalyptus eximia, the yellow bloodwood was transferred into the new genus Corymbia in 1995 when it was erected by Ken Hill and Lawrie Johnson. It is still seen under the earlier name in some works.
Eucalyptus racemosa, commonly known as snappy gum or narrow-leaved scribbly gum, is a species of small to medium-sized tree that is endemic to eastern Australia. It has smooth, mottled bark, lance-shaped to curved or egg-shaped adult leaves, flower buds in groups of between seven and fifteen, white flowers and cup-shaped, conical or hemispherical fruit.
Eucalyptus sclerophylla, known as the scribbly gum, is a tree native to eastern Australia. Very similar to the related Scribbly Gum , a better known tree. The best way of distinguishing the species is the smaller hemispherical to pear shaped gumnuts of Eucalyptus sclerophylla, being 0.6 cm by 0.6 cm in size. Flower buds are also smaller. sclerophylla literally means hard leaf. Both species have hard leaves, but Eucalyptus sclerophylla's leaves are particularly hard edged.
Eucalyptus signata is a species of evergreen tree native to eastern Australia. It is one of many trees known as the Scribbly Gum. The habitat is dry sclerophyll forests or swampy areas at low altitude. Occurring from Morisset, New South Wales up the coast and ranges to beyond the Queensland border. The original specimen was collected at the Brisbane River.
Telecrates laetiorella is a moth of the family Xyloryctidae. It is known from the Australian Capital Territory, New South Wales, Queensland, South Australia and Victoria.
Ogmograptis, the scribbly gum moth, is a genus in the family Bucculatricidae and was first described by Edward Meyrick in 1935, as a monotypic genus. They are found in the Australian Capital Territory, New South Wales and Queensland. However, in 2007, Cooke and Edwards argued that the patterning of the scribbles was different for each of the three eucalypts, Eucalyptus pauciflora, E. racemosa ssp. rossii, and E. delegatensis) and that it was likely that these differing patterns were caused by larvae from different species of scribbly gum moths.
Culama alpina is a moth in the family Cossidae. It was described by Kallies and D.J. Hilton in 2012. It is found in Australia, where it has been recorded from Tasmania, Victoria, New South Wales and the Australian Capital Territory. The habitat consists of alpine heath and snow gum woodlands.
Veil of Trees is an art installation within the grounds of the Royal Botanical Gardens in Sydney. The work was designed by Janet Laurence and Jisuk Han as part of the Sydney Sculpture Walk Program in 1999, to highlight the indigenous botanical history of the site. It consists of 21 glass panels among one hundred red forest gums which run along a one hundred metre grassed ridge between two parallel roads.
Marianne Horak is a Swiss-Australian entomologist who specialises in Australian Lepidoptera, particularly the phycitine and tortricid moths. She also did important research on the scribbly gum moths, during which eleven new species of Ogmograptis were discovered.
Eucalyptus pauciflora subsp. debeuzevillei, commonly known as Jounama snow gum, is a mallee or small tree that is native to a few mountain peaks in south-eastern Australia. It has smooth, shiny bark, glossy green lance-shaped to egg-shaped leaves, flower buds in groups of between nine and fifteen, white flowers and hemispherical or conical fruit. It differs from other subspecies of E. pauciflora in having angular flower buds.
Eucalyptus pauciflora subsp. pauciflora, commonly known as snow gum, cabbage gum or white sally is a tree or mallee that is endemic to eastern Australia. It has smooth bark, glossy green, lance-shaped, curved or elliptical leaves, flower buds in groups of between nine and fifteen, white flowers and cup-shaped, hemispherical or conical fruit.
