lignotuber. It has fissured, greyish to reddish brown, fibrous to stringy bark that tends to be papery on the outside. The leaves on young plants and on
coppice regrowth are egg-shaped to heart-shaped, long, wide, mid-green on the upper surface, paler below, and always have a
petiole. Adult leaves are thin, lance-shaped or slightly curved, long, wide on a petiole long and are a different colour on either side. The flower buds are arranged in groups of nine, eleven or thirteen on a
peduncle long, the individual buds on a
pedicel long. Mature buds are oval to almost spherical, about long and wide with a rounded
operculum. Flowering occurs between January and February or between April and November and the flowers are white. The fruit is a woody almost spherical
capsule with a small opening, long and wide. ==Taxonomy and naming==
