Two new synonyms in Western Australian Proteaceae: Isopogon heterophyllus and I. teretifolius subsp. petrophiloides
RYE, B.L. AND HISLOP, M., Nuytsia 28: 169–172 (2017)
A revision of the Hibbertia lineata (Dilleniaceae) species group
THIELE, K.R., Nuytsia 28: 173–191 (2017)
The Hibbertia lineata Steud. species group comprises six species endemic in south-western Western Australia. Hibbertia lineata is recircumscribed to include H. recurvifolia (Steud.) Benth., and H. polyancistra K.R.Thiele sp. nov., H. depilipes K.R.Thiele sp. nov., H. verrucosa (Turcz.) Benth., H. microphylla Steud. and H. papillata J.R.Wheeler are described and discussed. A key is provided to all taxa.
Neotypification and redescription of Amanita preissii (Basidiomycota), and reconsideration of the status of A. griseibrunnea
DAVISON, E.M., GIUSTINIANO, D., MCGURK, L.E., WATKIN, E.L.J. AND BOUGHER, N.L., Nuytsia 28: 193–204 (2017)
Amanita preissii (Fr.) Sacc. is redescribed. Re-examination of collections of A. griseibrunnea O.K.Mill. show that they do not differ significantly from A. preissii and the two species are combined. This species is common in the Perth IBRA subregion. Sequence data from the nuclear ribosomal internal transcribed spacer (ITS) region, 28S nuclear ribosomal large subunit rRNA (28S) region, RNA polymerase II (RPB2) region, β-tubulin region and translation elongation factor 1-α (EF1-α) region have been deposited in GenBank.
Revision of the south-western Australian genus Anticoryne (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 28: 205–215 (2017)
Anticoryne Turcz. comprises three species occurring in a relatively small portion of south-western Australia. Stamen morphology is of diagnostic importance for the genus, as is its very dark seed colour. In this revision of the genus, the new species A. melanosperma Rye is named and a lectotype is selected for A. ovalifolia (F.Muell.) Rye. All species have conservation priority.
Calandrinia holtumii (Portulacaceae), a new and unusual species from arid Western Australia
OBBENS, F.J., HANCOCK, L.P., EDWARDS, E. AND THIELE, K.R., Nuytsia 28: 217–223 (2017)
A new species of Calandrinia Kunth., C. holtumii Obbens & L.P.Hancock, from arid Western Australia is described and mapped. At this stage, the sectional placement for C. holtumii is uncertain. It has several anomalous morphological characters not previously recorded within the genus and has recently been shown to exhibit a stronger form of Crassulacean Acid Metabolism (CAM) than any other Australian species of Calandrinia.
A new species of Chamaescilla (Asparagaceae) from the mid-west of Western Australia
DAVIS, R.W. AND BROWN, A.P., Nuytsia 28: 225–227 (2017)
Stylidium miscellany 3: a synopsis of Robert Brown’s Stylidiaceae types and occasional notes on associated names
WEGE, J.A., Nuytsia 28: 229–246 (2017)
A synopsis of the 39 species of Stylidiaceae named by Robert Brown is presented and a full synonymy provided. Lectotypes are selected for the following Brown names: Levenhookia pusilla R.Br., Stylidium alsinoides R.Br., S. articulatum R.Br., S. assimile R.Br., S. caespitosum R.Br., S. calcaratum R.Br., S. corymbosum R.Br., S. crassifolium R.Br., S. diversifolium R.Br., S. eriorhizum R.Br., S. fasciculatum R.Br., S. floribundum R.Br., S. guttatum R.Br., S. tenuifolium R.Br. (= S. laricifolium Rich.), S. luteum R.Br., S. pedunculatum R.Br., S. reduplicatum R.Br. (= S. pilosum (Labill.) Labill.), S. spinulosum R.Br., S. tenellum R.Br. (= S. tenerum Spreng.) and S. violaceum R.Br. Stylidium robustum Sond. is newly synonymised under S. diversifolium and lectotypes are selected for two additional synonyms of this species, S. marginatum Sond. and S. pruinosum Sond. Stylidium pilosum is lectotypified and a neotype designated for S. pilosum var. brevius E.Pritz. Comments on the uncertain circumscription of S. armeria (Labill.) Labill. (of which S. melastachys R.Br. is a synonym) are provided.
