What is "leucosidea"

Leucosidea sericea, commonly known as ouhout in Afrikaans, is an evergreen tree or large shrub that grows in the Afromontane regions of southern Africa. It is the sole species in the genus Leucosidea. The English name "old wood" is simply a direct translation of the Afrikaans words "ouhout" or "oudehout", meaning the same thing.

The genus name Leucosidea is a form of the Greek word λευκός (leukos), meaning "shining white", although in botany the root is more often used less specifically to indicate something of a generally white or gray appearance. The second or specific name sericea means "silky" and comes from σηρικός (serikos), which means both "silky" and "from the land of silk"; it refers to the silky hairs that cover the new buds and young leaves of the tree.
