  • Etymology: "The epithet is derived from the Latin perplexus, meaning ‘obscure, confused, intricate’. It firstly refers to the complicated and confused taxonomic history of this taxon based on the misapplications of obscure, polymorphic fruit character traits formerly used to circumscribe annual taxa in Western Australia. This epithet refers also to the intricate, entanglement of stems in large individual plants and to plants often found growing in dense colonies."
