About Eucalyptus haemastoma Sm.
Eucalyptus haemastoma Sm. is a tree that typically reaches a height of 12 to 15 meters (39 to 49 feet) and forms a lignotuber. Its bark is smooth and colored white, silvery grey, or yellow, with distinctive insect scribble markings. Young plants and coppice regrowth have elliptical, oblong, or egg-shaped leaves that are 70–150 mm (2.8–5.9 in) long and 20–60 mm (0.79–2.36 in) wide. Adult leaves are lance-shaped or curved, the same shade of green on both sides, 90–210 mm (3.5–8.3 in) long and 15–35 mm (0.59–1.38 in) wide, attached to a 12–20 mm (0.47–0.79 in) long petiole. Flower buds are arranged in groups of nine to fifteen in leaf axils, growing on an unbranched peduncle 5–25 mm (0.20–0.98 in) long, with individual buds borne on 3–7 mm (0.12–0.28 in) long pedicels. Mature buds are oval, 4–6 mm (0.16–0.24 in) long and 3–4 mm (0.12–0.16 in) wide, with a conical to rounded operculum. Flowering occurs between July and November, and the flowers are white. The fruit is a woody, conical or hemispherical capsule 5–9 mm (0.20–0.35 in) long and 7–11 mm (0.28–0.43 in) wide, with valves positioned near the rim level. This species intergrades with another scribbly gum, Eucalyptus racemosa, mainly in the southern part of the Sydney area. A third scribbly gum, Eucalyptus rossii, grows further inland, on the slopes and tablelands between Tenterfield and Bombala. This scribbly gum grows in woodland on shallow sandy soil formed from sandstone. It occurs in the Sydney region between Lake Macquarie and the Royal National Park.
