Taxonomy and naming

Dendrobium carronii was first formally described in 1982 by Bill Lavarack and Phillip Cribb and the description was published in the journal Austrobaileya.{{cite web|title=Dendrobium carronii|url= https://id.biodiversity.org.au/instance/apni/503969|publisher=APNI|accessdate=20 November 2018}} The specific epithet (carronii) honours William Carron (1823 - 1876), botanist on the ill-fated 1848 expedition of Edmund Kennedy.

Distribution and habitat

The pink tea tree orchid usually grows in stunted open forest usually near areas that are flooded in the wet season and often on Melaleuca viridiflora trees. It is found from Bamaga on the tip of the Cape York Peninsula to the McIlwraith Range in Queensland and on the southern coast of New Guinea.

Conservation

This orchid is classed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999. The main threat to the species is illegal collection of plants.
