William A. Sayer,[7][8] botanical collector associate of Mueller, collected specimens of it about "Mt Bellenden Ker" in 1887 as recorded on the "9/87" label written by Ferdinand von Mueller on his herbarium specimen sent on 15 March 1892 to Kew Royal Botanic Gardens, UK.[9]
"On the Russell River; W. Sayers [sic]", is its location and collector recorded in Ferdinand von Mueller’s 1889 published original botanical description of this species.[1] The region of the Russell River is the same as the region of Mount Bellenden Ker.
Mueller’s 1889 original botanical description of the species was under the name Oldenlandia psychotrioides.[1][4] In 1892 he re-diagnosed it as constituting a species of this genus Wendlandia, after newly describing Wendlandia basistaminea as a species. He provided some comparative notes on them and related species of this genus.[2][3]
