Xanthosia pilosa

Xanthosia pilosa, known as the woolly xanthosia is a species of the plant family Apiaceae, but sometimes also placed in Araliaceae or Mackinlayaceae.[4] It grows in south eastern Australia, in Tasmania, Victoria, New South Wales and Queensland.[5] This species is known for the variability of form, which has caused difficulties in identification and taxonomy. The specific epithet pilosa comes from the Latin, meaning softly hairy.[4]
