Melaleuca cajuputi, commonly known as cajuput or white samet is a plant in the myrtle family, Myrtaceae and is widespread in Australia, Southeast Asia, New Guinea and the Torres Strait islands.

It is a medium to tall tree with papery bark, silvery new growth and white or greenish flower spikes.

[2][3]Melaleuca cajuputi was first formally described in 1809 by Thomas Powell in Pharmacopoeia of the Royal College of Physicians of London with a reference to an earlier (1747) description by Rumphius in Herbarium Amboinense.

[4] The specific epithet (cajuputi) is probably from the Indonesian or Malay name for the plant, kayu putih, meaning "white tree".

[3][5][6] Three subspecies have been described, and the names have been accepted by Plants of the World Online:[1] The epithet cumingiana honours Hugh Cuming[3] and platyphylla means "flat- or wide-leaved".

Barlow occurs in Myanmar, Thailand, Vietnam, Malaysia and Indonesia (Sumatra, West Java and south-west Kalimantan).

platyphylla Barlow occurs in New Guinea, the Torres Strait islands and north-western Queensland as far south as Cairns.
