Description and taxonomy
Phebalium daviesii is a medium sized shrub to about 3 metres tall. It has cuneate-shaped leaves, 2 to 3 centimetres long, with a distinctive bi-lobed apex. The lower leaf surface is silvery, while the upper surface is dark green with a row of glands along each side. The pale yellow flowers occur in groups of 5 to 8 at the ends of the branchlets. The flowers are five-lobed, symmetrical and hermaphrodite. The stamens protrude from the flowers to about twice the length of the petals (Curtis & Morris 1975).
Phebalium daviesii is a member of the Rutaceae, a family that is common in sclerophyll and heath vegetation in Australia. Phebalium is a genus in the Boronieae tribe, which is the largest of the six Australian Rutaceae tribes and the one with the highest level of diversity and species' endemism (Armstrong 1983). The 33 taxa in the Rutaceae family in Tasmania are all in the Boronieae tribe, with 18 of these being endemics (Buchanan 2009). Phebalium daviesii is now the only member of the genus Phebalium in Tasmania, others having been assigned to Leionema or Nematolepis (Wilson 1998, Buchanan 2009).
