44-EUCALYPTUS TERETICORNIS Sm. Bot N. Holl.
Local name: Nilgiri
Family: Myrtaceae
Location: In front of Botanical garden, in front of Shastri memorial hall.
Characters: Eucalyptus tereticornis is a tree that typically grows to a height of 20–50 m (66–164 ft) and forms a lignotuber. The trunk is straight, usually unbranched for more than half of the total height of the tree and has a girth of up to 2 m (6 ft 7 in) dbh. Thereafter, limbs are unusually steeply inclined for a Eucalyptus species. The bark is shed in irregular sheets, resulting in a smooth trunk surface coloured in patches of white, grey and blue, corresponding to areas that shed their bark at different times. Young plants and coppice regrowth have dull bluish green, egg-shaped leaves that are 60–130 mm (2.4–5.1 in) long and 30–80 mm (1.2–3.1 in) wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, 80–220 mm (3.1–8.7 in) long and 10–35 mm (0.39–1.38 in) wide, tapering at the base to a petiole 13–30 mm (0.51–1.18 in) long. The flower buds are arranged in leaf axils in groups of seven, nine or eleven on an unbranched peduncle 7–25 mm (0.28–0.98 in) long, the individual buds on pedicels 2–6 mm (0.079–0.236 in) long. Mature buds are an elongated oval shape, 9–16 mm (0.35–0.63 in) long and 3–6 mm (0.12–0.24 in) wide with a conical to horn-shaped operculum that is much longer than the floral cup. Flowering has been recorded in most months and the flowers are white. The fruit is a woody, hemispherical capsule 2–6 mm (0.079–0.236 in) long and 4–8 mm (0.16–0.31 in) wide with the valves prominently protruding.
General use: The tree has a strong, hard and durable heartwood, with a density of about 1100 kg m−3. It is used for construction in heavy engineering, such as for railway sleepers. The leaves of E. tereticornis are used in the production of cineole based eucalyptus oil.
