An account of the reed triggerplants (Stylidium sect. Junceae: Stylidiaceae)
WEGE, J.A., Nuytsia 24: 215–247 (2014)
This taxonomic review of Stylidium sect. Junceae Mildbr. recognises eight species endemic to south-western Western Australia and presents a new circumscription for S. junceum R.Br., the original description of which was based on a mixed gathering comprising three distinct taxa. A lectotype is designated in order to fix the application of the name S. junceum to one of these, a species with a diminutive habit, pale creamy yellow to apricot-pink corolla lobes, and a column morphology that is unique within the genus. A neotype is designated for S. junceum subsp. brevius (E.Pritz.) Carlquist, which is not recognised as distinct. Stylidium scariosum DC. is reinstated and S. hesperium Wege, S. hygrophilum Wege, S. paludicola Wege and S. thryonides Wege described as new. Revised descriptions are provided for S. squamosotuberosum Carlquist and S. laciniatum C.A.Gardner, with S. junceum var. volubile F.Muell. lectotypified and placed into synonymy under the latter species. Descriptions, distribution maps, illustrations and photographs are supplied for each species, and an identification key provided. Stylidium hygrophilum has a highly localised distribution on the Blackwood Plateau south of Busselton and may warrant listing as Threatened. Stylidium paludicola, a species confined to swamps on the Swan Coastal Plain, is also listed as being of conservation concern, with targeted surveys required to better understand its conservation status.
A new subspecies of the threatened monocalypt Eucalyptus insularis (Myrtaceae) from Western Australia
NICOLLE, D., BROOKER, M.I.H. AND FRENCH, M.E., Nuytsia 24: 249–253 (2014)
Two subspecies are here recognised in the geographically rare and taxonomically isolated Eucalyptus insularis Brooker. Eucalyptus insularis subsp. insularis is known only from North Twin Peak Island in the Recherche Archipelago, about 90 km east-south-east of Esperance. Eucalyptus insularis subsp. continentalis D.Nicolle & Brooker subsp. nov. is known only from several small populations near Cape Le Grand on the mainland, about 25 km south-east of Esperance, and differs from the type subspecies in its low shrubby habit, smaller adult leaves with obscure tertiary venation and irregularly-shaped oil glands, more strongly pendulous inflorescences, and its generally smaller buds and fruits.
Brachyloma stenolobum (Ericaceae: Styphelioideae: Styphelieae), a new, white-flowered species for Western Australia
HISLOP, M. AND CRANFIELD, R.J., Nuytsia 24: 255–261 (2014)
A new member of Brachyloma Sond. sect. Lissanthoides Benth. is described and illustrated. Two keys are presented: an interim key to the Western Australian species of Brachyloma, and an Australia-wide key to the species of sect. Lissanthoides. The presence of two lineages in the genus, distinguished by molecular phylogenetics and morphology, is discussed, and the case for future elevation of sect. Lissanthoides to generic status is examined.

A key is supplied for sect. Astraea and line illustrations or images for seven of the new taxa. Thryptomene urceolaris F.Muell. is selected as the lectotype of T. sect. Thryptocalpe Stapf. Lectotypes are also selected for T. stenophylla F.Muell. and for Scholtzia decandra F.Muell., which is a synonym of T. saxicola (A.Cunn. ex Hook.) Schauer. Most of the new taxa are conservation-listed. Species or species groups needing further study are noted.
Amanita drummondii and A. quenda (Basidiomycota), two new species from Western Australia, and an expanded description of A. walpolei
DAVISON, E.M., GIUSTINIANO, D., MCGURK, L.E., SYME, K. AND ROBINSON, R.M., Nuytsia 25: 1–13 (2015)
Three species of Amanita Pers. are documented from Western Australia. Amanita drummondii E.M.Davison is described from the south-west region; it appears to be widespread but infrequent. Amanita quenda E.M.Davison is described from the Perth Metropolitan area. Amanita walpolei O.K.Mill. is redescribed to include additional collections, drawing attention to the presence of clamp connections in all tissues. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank.
Synostemon hamersleyensis (Phyllanthaceae), a new species endemic to the Pilbara, Western Australia
TELFORD, I.R.H. AND NAAYKENS, J., Nuytsia 25: 31–37 (2015)
Synostemon hamersleyensis I.Telford & Naaykens (Phyllanthaceae), morphologically similar to but distinct from Sauropus aphyllus J.T.Hunter & J.J.Bruhl, is named as new and its habitat, distribution and conservation status are discussed. The new species is endemic to ironstone formations of the Hamersley Range in the Pilbara, central Western Australia.

The Hibbertia hypericoides (DC.) Benth. species group comprises four species endemic in Western Australia. Hibbertia hypericoides is the most widespread species of Hibbertia Andrews in Western Australia, and exhibits significant and complex variation. The new subspecies H. hypericoides subsp. septentrionalis K.R.Thiele & Cockerton is described to accommodate a long-recognised form that occurs in the northern part of its range. The new species H. cockertoniana K.R.Thiele, previously included in H. hypericoides, is described. Descriptions are also provided for H. hypericoides subsp. hypericoides, H. silvestris Diels and H. furfuracea (R.Br. ex DC.) Benth., the other taxa in the group.
Hibbertia paranthera (Dilleniaceae), a remarkable new species from the Prince Regent River in Western Australia
THIELE, K.R., Nuytsia 25: 307–312 (2015)
A distinctive and remarkable new species in Hibbertia Andrew subgen. Pachynema (R.Br. ex DC.) J.W.Horn is described and illustrated. Hibbertia paranthera K.R.Thiele sp. nov. differs from all other species in subgen. Pachynema (and in the whole of Hibbertia) in having an androecium reduced to two large stamens, and a corolla of three petals. The new species is currently known from two populations c. 30 km apart in sandstone habitats in a remote area in Prince Regent National Park, between the Prince Regent River and Prince Frederick Harbour.
A taxonomic revision of the Stylidium brunonianum alliance (sect. Saxifragoidea: Stylidiaceae)
WEGE, J.A., Nuytsia 25: 313–342 (2015)
A morphological assessment of Stylidium brunonianum Benth. and its allies recognises eight taxa, all of which are endemic to the south-west of Western Australia. Following examination of type material and field work, a narrower circumscription of S. brunonianum is presented, S. tenue Sond. is reinstated and the following five taxa are newly described: S. araeophyllum Wege, S. neurophyllum Wege, S. purpureum Wege, S. spiciforme Wege and S. tenue subsp. majusculum Wege. A revised description is provided for S. lowrieanum Carlquist, a conservation-listed species from the Leeuwen-Naturaliste Ridge. Lectotypes are selected for S. brunonianum, S. tenue and S. brunonianum var. minor Benth., with the varietal name newly placed into synonymy under S. tenue. A lectotype is also designated for the name S. striatum Lindl. var. glaucum Benth. (based on collections of S. lowrieanum, S. neurophyllum, S. bellum Wege and S. rosulatum Wege) to fix its application as a synonym of S. rosulatum. A dichotomous key to the S. brunonianum alliance is provided along with photographs of key features and distribution maps.
Fifty new species of vascular plants from Western Australia—celebrating fifty years of the Western Australian Botanic Garden at Kings Park
BARRETT, R.L., Nuytsia 26: 3–20 (2015)
This paper introduces a special issue of Nuytsia containing seven collaborative papers naming 50 new species of Western Australian vascular plants. It has been compiled to celebrate the 50th anniversary of the opening of the Western Australian Botanic Garden at Kings Park. Several species are named after former Kings Park staff to honour their contributions to botany in Western Australia, including one that occurs naturally in the Kings Park bushland and is named after one of the designers of the Botanic Garden. Field research by Kings Park staff across Western Australia, including the rediscovery of Auranticarpa resinosa (Domin) L.W.Cayzer, Crisp & I.Telford, missing for 180 years, is documented.
