Appearance
"Eucalyptus sweedmaniana" is a sprawling or prostrate mallee that grows to a height of about 1 m, a width of 5 m and forms a lignotuber. It has smooth, shiny silvery grey bark that fades to dull grey. Young plants have reddish green, lance-shaped to elliptical leaves that are 42–63 mm long and 19–25 mm wide on a petiole 8–15 mm long. Adult leaves are the same shade of glossy green on both sides, broadly lance-shaped, 165–263 mm long and 45–67 mm wide on thick, flattened petiole 38–48 mm long. The flower buds are arranged singly in leaf axils on a down-curved, winged peduncle. The mature flower buds are red, square in cross section with prominent wings, with a red, pyramid-shaped operculum. Flowering has been observed from November to February and the flowers are pink. The fruit is a woody, cube-shaped to oblong capsule that is square in cross-section, 34–38 mm long and 30–41 mm wide with prominent wings and the valves enclosed below the rim.Distribution
This mallee is only known from the lower coastal slopes of Mount Arid where it is exposed to significant salt spray.Status
