DescriptionEdit

Corymbia pauciseta is a tree that typically grows to a height of 6 m (20 ft) and forms a lignotuber. It has rough, grey, tessellated bark on some or all of the trunk, smooth creamy white to pale grey bark above. The crown of the tree has both intermediate and adult leaves that are the same shade of dull green on both sides, heart-shaped, egg-shaped or lance-shaped, 90–195 mm (3.5–7.7 in) long, 27–90 mm (1.1–3.5 in) wide and sessile or on a petiole up to 5 mm (0.20 in) long. The tree usually loses its leaves in the dry season. The flower buds are arranged in leaf axils on a branched peduncle 2–15 mm (0.079–0.591 in) long, each branch of the peduncle with seven buds on pedicels 9–32 mm (0.35–1.26 in) long. Mature buds are pear-shaped, 6–7 mm (0.24–0.28 in) long and 4–5 mm (0.16–0.20 in) wide with a rounded operculum. Flowering has been observed in October and November and the flowers are creamy white. The fruit is a thin-walled capsule 8–15 mm (0.31–0.59 in) long and 7–12 mm (0.28–0.47 in) wide with the valves enclosed in the fruit.[2][3][4]

Taxonomy and namingEdit

Corymbia pauciseta was first formally described in 1995 by Ken Hill and Lawrie Johnson.[3][5] The specific apithet (pauciseta) is from the Latin paucus meaning "few" and seta "bristle", referring to the leaves and shoots of this species compared to those of Corymbia confertiflora.[3]

Distribution and habitatEdit

This eucalypt mainly grows in low woodland usually in flat places. It is locally common but occurs sporadically in the north-eastern Northern Territory, between Maningrida and Gove but mainly in Arnhem Land.[2][3]
