Today, 5 Apr. 2022, two research papers by Tim and co-authors were published online…
(1) J. Kellermann, T.A. Hammer & H.R. Toelken, Uncovering the correct publication date, spelling and attribution for the basionym of Hibbertia subg. Hemistemma (Dilleniaceae). Taxon 71.
The authors resolve a complex nomenclatural issue, namely the spelling, author ship and correct publication date of Hemistemma, the basionym of Hibbertia subg. Hemistemma, which contains many well-known species from eastern Australia. It was published in the journal of the International Association of Plant Taxonomists, Taxon.
(2) T.A. Hammer & K.R. Thiele, Hibbertia archeri (Dilleniaceae), a new and rare species from Western Australia with transcontinental affinities. Swainsona 36: 67-70 (1.6mb PDF).
A new species of Hibbertia from north-east of Esperance is published today in Vol. 36 the State Herbarium’s journal Swainsona online. It is only known from two populations, c. 40 km apart. It is most closely related to species of the Hibbertia stricta species group from eastern Australia, e.g. H. deviatata, H. setivera and H. riparia.
