Alphitonia petriei, known as the white ash, is a rainforest tree in the family Rhamnaceae. It grows in eastern and northern Australia. Other common names include red ash, white-leaf, pink almond and pink ash. It was originally collected from the Johnston River near Kuranda, and named in 1925 by K.W. Braid. The authors gave it the species name petriei after W.R. Petrie, who alerted them to its distinctness.
