About

Alphitonia petriei, commonly known as the white ash, is a rainforest tree in the family Rhamnaceae from eastern and northern Australia. Other common names include red ash, white-leaf, pink almond and pink ash. It was originally collected from the Johnstone River in October 1917 by H. Ladbrook, but the designated type for this species was collected by Cyril Tenison (C.T.) White in March 1922 from the Barron River near Kuranda. It was described and named in 1925 by K.W. Braid and White who assigned the species epithet petriei in honour of W.R. Petrie, who alerted them to its distinctness.

Alphitonia petriei is usually found as a small tree around 20 metres (66 feet) tall. However, it has been recorded at 40 metres (130 feet) tall with a stem diameter of 60 cm in Queensland.
