Opisthiolepis is a genus of a sole described species of large trees, constituting part of the plant family Proteaceae. The species Opisthiolepis heterophylla most commonly has the names of blush silky oak, pink silky oak, brown silky oak and drunk rabbit. These large trees, up to 30 m (100 ft) tall, are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. While restricted to this region, within their range they occur widely in rainforests, more common in the tablelands and mountains and described as common on the Atherton Tableland.
