Heteropyxis

H. canescens
H. dehniae
H. natalensis

Heteropyxis is a genus which includes three species of small evergreen trees, the sole genus in family Heteropyxidaceae. The species of Heteropyxis are native to southern Africa.

H. natalensis, commonly known as Lavender Tree or Laventelboom, ranges from Zimbabwe through Limpopo, Mpumalanga and KwaZulu-Natal of South Africa. It is a slender, upright tree which grows 5-7 meters in height, at forest margins, rocky outcrops, hillsides, and termite mounds. It bears panicles of fragrant flowers, cream to pale yellow in colour, from December to March.

Many classification schemes place Heteropyxis within family Myrtaceae. Recent embryological and DNA analyses seem to indicate that Heteropyxis and Psiloxylon, the sole member of family Psiloxylaceae are sister taxa to the Myrtaceae, but diverged before the origin of the common ancestor of the Myrtaceae.
