Description

Eucalyptus megasepala is a tree that typically grows to a height of 10–20 m (33–66 ft) and forms a lignotuber. The bark on the trunk and branches is greyish brown, fibrous or stringy, and furrowed. Adult leaves are lance-shaped or curved, the same dull green on both sides, 100–200 mm (3.9–7.9 in) long and 15–30 mm (0.59–1.18 in) wide, tapering to a petiole 10–22 mm (0.39–0.87 in) long. The flower buds are arranged in groups of three in leaf axils on an unbranched peduncle 9–26 mm (0.35–1.02 in) long, the individual buds on pedicels 3–10 mm (0.12–0.39 in) long. Mature buds are oval to pear-shaped, 10–13 mm (0.39–0.51 in) long and 5–8 mm (0.20–0.31 in) wide with a rounded operculum that has four prominent ribs. Flowering occurs between April and July and the flowers are white or creamy-white. The fruit is a woody, cup-shaped to more or less cylindrical capsule 14–23 mm (0.55–0.91 in) long, 10–16 mm (0.39–0.63 in) wide and often more or less square in cross-section.

Taxonomy and naming

Eucalyptus megasepala was first formally described in 2006 by Anthony Bean and the description was published in the journal Austrobaileya from a specimen collected near Jowalbinna (near Laura). According to Bean, the specific epithet (megasepala) is derived from the Greek mega (large) and sepalum (sepal), referring to the size of the sepals of this species compared to those of the related E. tetrodonta. Sepalum is however New Latin.
