The author from the Australian National Herbarium (Canberra) describes a new species of Ptilotus from Arckaringa Station in the north of South Australia. It is currently it is known only from a single population on a gypseous breakaway escarpment.

In this paper, the authors from Adelaide and Perth clarify uncertainties about a taxon that has been confused in South Australia with the Western Australian Hibiscus huegelii (Endl.) Fryxell. It was also known as Hibiscus huegelii var. leptochlamys Benth. and Alyogyne pinoniana var. microandra in the past. The taxon is published here at species level, described, illustrated and distinguished from related species.
