Bark, continuing to small branches, is a pale grey brown colour, rough and scaly in texture with patches of exposed resin (kino) often visible (2). Bark is shed in irregular patches or in short broad strips (2). Longitudinal veins are obvious (5). The solid primary stalk (peduncle) is rounded and up to 15mm long, whereas individual stalks (pedicels) are non-existent (sessile) or only a few millimetres long (3). More than 200 full colour photographs and detailed descriptions explaining leaf, bark, flower, fruit and other tree characteristics. Older leaves often turn red before falling (5). Venation is faint but visible, showing numerous straight lateral veins (5). Venation except for mid vein is very faint (5). This tool makes Australia’s most significant group of plants, the eucalypts, available to all from the enthusiastic amateur to the practical users and to the professional scientists. Clusters (panicles) of white flowers, borne at the end of branches, measure 2 to 3cm in diameter and blossom over late spring and early summer (3). Information such as distribution range of tree species has been put together using a selection of sources including various Botanical Gardens (see link above). Leaves feature mostly entire margins (edges) and are characteristically rather strong, hairless, smooth and leathery in texture. Leaf apex gradually narrows into a fine point; base shape is asymmetric (oblique). Juvenile leaves can be more than 20cm long with entire margins, broadly lanceolate to nearly obovate in shape. Known as Bush Medicine, Australian Aborigines are the original people of this land and already had the knowledge and the way in the Medicinal Use of Eucalyptus. Distribution: NSW central coast to southern Qld. Depending on conditions, it can be up to 50m tall, but a height of 15-30m is more common (Picture 1). This includes species endemic to Australia and species that are listed as threatened under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. It also has been extensively planted as an ornamental tree outside its natural habitat (Picture 1). The Swamp Mahogany reaches a height of about 30m with main branches starting at more than half the height of the normally straight trunk (Picture 1). Otherwise bark is very smooth in texture and mainly whitish grey, showing longitudinal streaks of darker grey, and areas with yellow to brownish tones (2). Leaf apex very gradually narrows into a fine tip, base shape is cuneate (wedge-shaped). The woody fruit varies from barrel-shaped to more urn-shaped and measures up to 12mm in length. Approximately three-quarter of forests in Australia is Eucalypt forests. We envisage a public inspired by and appreciative of eucalypts. Red Box (Eucalyptus polyanthemos) is a small to medium-sized tree with alternate leaves, white, cream or pink flowers, and a grey bark with white patches. This very tall tree species and can reach more than 60m in height with a trunk diameter of more than 2m (Picture 1). Eucalypts are being grown on plantations in many countries including the United States, Brazil, Morocco, Portugal, South Africa, Israel, and Spain. The umbel-shaped inflorescence consists of up to seven flowers that are supported by a primary stalk (peduncle), which is rounded and up to 2cm long. It is shed in small irregular plates exposing dark grey (blue grey) coloured patches of fresh bark that cause the mottling effect (more noticeable in wet times) (2). Eucalypts dominate Australia’s landscape like no other plant group in the world. The bark on the lower half of the trunk is brown in colour with a rough and flaky texture, whereas the top half of the trunk and upper branches feature a smooth greyish green bark (2).
