The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. Please reach out to us if you have any questions or concerns.
The notice period
started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Monday, 2 March 2026 +08:00.
Calytrix watsonii (F.Muell. & Tate) C.A.Gardner is reinstated and four species with conservation priority are described: C. hislopii Rye, C. patrickiae Rye, C. sagei Rye and C. viscida Rye. Keys are given for the species groups that include these taxa. The current study has eliminated about half of the informal names that have been in use for Western Australian members of the genus. Several species complexes that need further study are noted.
Typification and application of names in Drosera section Arachnopus
BARRETT, R.L. AND LOWRIE, A., Nuytsia23: 527–541 (2013)
Taxonomic review of the Drosera indica L. (Droseraceae) complex requires the clarification of a number of published names. This paper is focussed on the application of names applying to taxa occurring in Australia. Two lectotypes are chosen and one neotype is designated for names historically listed as synonyms of D. indica. Drosera serpens Planch. and D. angustifolia F.Muell. are lectotypified. A neotype is selected for D. hexagynia Blanco as no original material is known. Drosera hexagynia is considered to be a synonym of D. indica. Drosera angustifolia and D. indica f. robusta F.M.Bailey are here considered to be synonyms of D. finlaysoniana Wall. ex. Arn. Drosera angustifolia var. purpuriflora F.Muell. ex Diels is an illegitimate name. Notes are provided on D. hartmeyerorum Schlauer, the only other named Australian taxon in this species complex. Characteristics of the seeds, anthers and glandular hairs are considered diagnostic at the species level. Illustrations of key identifying features and full descriptions of the Australian species are provided.
A baker’s dozen of new wattles highlights significant Acacia (Fabaceae: Mimosoideae) diversity and endemism in the north-west Kimberley region of Western Australia
MASLIN, B.R.,BARRETT, M.D. AND BARRETT, R.L., Nuytsia23: 543–587 (2013)
Thirteen new species of Acacia Mill. from the Kimberley region in northern Western Australia are described. These species are accommodated into three sections of the genus. Acacia sect. Juliflorae (Benth.) Maiden & Betche: A. anastomosa Maslin, M.D.Barrett & R.L.Barrett, A. camptocarpa Maslin, M.D.Barrett & R.L.Barrett, A. cyclocarpa Maslin, M.D.Barrett & R.L.Barrett, A. diastemata Maslin, M.D.Barrett & R.L.Barrett, A. phacelia Maslin, M.D.Barrett & R.L.Barrett and A. synantha Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Plurinerves (Benth.) Maiden & Betche: A. anserina Maslin, M.D.Barrett & R.L.Barrett, A. obtriangularis Maslin, M.D.Barrett & R.L.Barrett, A. orthotropica Maslin, M.D.Barrett & R.L.Barrett and A. perpusilla Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Lycopodiifoliae Pedley: A. claviseta Maslin, M.D.Barrett & R.L.Barrett, A. dimorpha Maslin, M.D.Barrett & R.L.Barrett and A. prolata Maslin, M.D.Barrett & R.L.Barrett. Notes are provided on A. gracillima Tindale (Acacia sect. Juliflorae) which provisionally includes a poorly known, distinctive entity in need of further taxonomic scrutiny. Except for A. claviseta, which extends to the Northern Territory, the new species are endemic to the Kimberley region. Eleven of the new species (all except A. camptocarpa and A. claviseta) are endemic to the high-rainfall area of the north-west Kimberley, highlighting significant levels of plant endemism in this region. A number of these species are geographically restricted (three are known only from the type) and all except A. prolata are treated as Priority taxa under the Department of Parks and Wildlife’s Conservation Codes for Western Australian Flora. Most of the new species are killed by fire and their distributions are restricted to rocky, presumably naturally fire-limiting sites.
Amanita lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes
DAVISON, E.M.,MCGURK, L.E.,BOUGHER, N.L.,SYME, K. AND WATKIN, E.L.J., Nuytsia23: 589–606 (2013)
Three species of Amanita Pers. are documented from Western Australia. Amanita lesueurii E.M.Davison is described from the mid-west region. It is distinguished by its small to medium fruiting bodies with a white pileus and white universal veil (both of which become vinaceous-buff or grey with age), white gills, short white stipe with a small obconic or turbinate bulb, white partial veil, amyloid, elongate to cylindrical spores, and no clamp connections. Amanita wadjukiorum E.M.Davison is described from the Perth metropolitan area. It has medium to large fruiting bodies with a cream pileus that ages milky coffee to snuff brown, a pale grey or buff universal veil that ages hazel to drab, cream gills, grey to buff stipe with a napiform or fusiform bulb, white to cream to vinaceous-buff partial veil that disappears with age, amyloid, ellipsoid to elongate spores and no clamp connections. Amanita fibrillopes O.K.Mill., which was previously only known from the type locality, is a widespread but misidentified species. It has small to large fruiting bodies with a pale peach to pale salmon pileus that rapidly ages cream, a white universal veil that rapidly ages buff or milky coffee, white gills that age buff, white or pale pink stipe with a spherical or obconic or tapered bulb, white or buff apical partial veil that disappears with age, inamyloid, ellipsoid to elongate spores and no clamp connections. 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.
Acacia equisetifolia, a rare, new species of Acacia sect. Lycopodiifoliae (Fabaceae: Mimosoideae) from the Top End of the Northern Territory
MASLIN, B.R. AND COWIE, I.D., Nuytsia24: 1–5 (2014)
Acacia equisetifolia Maslin & Cowie, a new species known only from Kakadu National Park, Northern Territory, is described. The new species, formerly known by the phrase name Acacia sp. Graveside Gorge (V.J. Levitzke 806), is very closely related to A. hippuroides Heward ex Benth. which occurs about 1,000 km to the south-west, in the western Kimberley region of Western Australia. The main morphological features separating these two species are the nature of branchlet and peduncle indumentum and various pod attributes.
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 2. Cyathostemon
TRUDGEN, MALCOLM E. AND RYE, B.L., Nuytsia24: 7–16 (2014)
Three new species of Cyathostemon Turcz. are described, illustrated and mapped, and a key is given to the seven named species in the genus. The new species are C. divaricatus Trudgen & Rye, C. gracilis Trudgen & Rye and C. verrucosus Trudgen & Rye. This has reduced the number of taxa known by informal names to seven, most of which belong to a difficult species complex that needs a great deal more work to resolve.
Two new species of Calandrinia (Portulacaceae) from southern Western Australia
The new species Lasiopetalum adenotrichum R.A.Meissn. & Rathbone is here described. It is a priority species for conservation in Western Australia and is endemic to Fitzgerald River National Park.
New species from the Leucopogon pulchellus group (Ericaceae: Styphelioideae: Styphelieae)
Five new species and one new subspecies of Leucopogon R.Br. (L. audax Hislop, L. corymbiformis Hislop, L. darlingensis Hislop, L. decrescens Hislop, L. subsejunctus Hislop and L. darlingensis subsp. rectus Hislop) are described, illustrated and mapped. Aspects of the morphology and taxonomy of the informal Leucopogon pulchellus Sond. group are discussed and an interim key is provided to distinguish between the five informal groups and other unplaced species of Leucopogon s. str. from Western Australia.
Scaevola xanthina (Goodeniaceae), a new yellow-flowered species from the south coast of Western Australia
SHEPHERD, K.A. AND HISLOP, M., Nuytsia24: 95–99 (2014)
Scaevola xanthina K.A.Sheph. & Hislop, a new species readily distinguished by its prostrate habit and yellow flowers, is here described. This species is geographically restricted and is currently only known from Mount Manypeaks Nature Reserve. It is listed according to Department of Parks and Wildlife Conservation Codes for Western Australia Flora as a Priority Two taxon under the phrase-name Scaevola sp. Waychinicup (E.M. Sandiford EMS 1336). Images and an amendment to the Flora of Australia key to Scaevola L. are included.
Grevillea saxicola (Proteaceae), a new species from the Pilbara of Western Australia
A new species of Grevillea R.Br. ex Knight, G. saxicola S.J.Dillon, is described. An amendment to an existing key of Grevillea is provided to include the new taxon, which has conservation priority.
Description of Gastrolobium argyrotrichum (Fabaceae: Mirbelieae), with taxonomic notes on some other species with bicoloured calyx hairs
HISLOP, M.,WEGE, J.A. AND WEBB, A.D., Nuytsia24: 113–122 (2014)
Gastrolobium argyrotrichum Hislop, Wege & A.D.Webb, a rare species endemic to the Metricup scarp south of Dunsborough in south-western Australia, is formally described. A key to species of Gastrolobium R.Br. with a bicoloured calyx indumentum and predominantly yellow or orange flowers is presented. Taxonomic notes are provided for G. coriaceum (Sm.) G.Chandler & Crisp, G. dilatatum (Benth.) G.Chandler & Crisp, G. dorrienii (Domin) G.Chandler & Crisp, G. retusum Lindl., G. rhombifolium G.Chandler & Crisp and G. whicherense G.Chandler & Crisp in order to facilitate future taxonomic work on the genus.
Two new and rare species of Ptilotus (Amaranthaceae) from the Eneabba sandplains, Western Australia
DAVIS, R.W.,HAMMER, T.A. AND THIELE, K.R., Nuytsia24: 123–129 (2014)
Ptilotus clivicolus R.W.Davis & T.Hammer and P. falcatus R.W.Davis & T.Hammer, are described as new. The two species are very closely related to each other and are relatively distantly related to other Ptilotus R.Br. taxa. They have identical ITS and matK molecular sequences, but are morphologically distinctive. Both species are rare and endemic to sandplains near Eneabba in south-west Western Australia.
Two new species of Acacia (Fabaceae: Mimosoideae) with conservation significance from Banded Iron Formation ranges in the vicinity of Koolyanobbing, Western Australia
Two geographically restricted species of Acacia Mill., A. haematites Maslin and A. shapelleae Maslin, from Banded Iron Formation (BIF) ranges in the south-west extremity of the arid zone of Western Australia are described. Acacia haematites occurs on the Koolyanobbing Range (close to the township of Koolyanobbing) while A. shapelleae occurs on the Helena and Aurora Range which is located about 40 km to the north of Koolyanobbing. Both these geographically restricted species occur in areas of mining interests and are therefore classified as Priority One under Department of Parks and Wildlife Conservation Codes for Western Australian Flora. The two new species belong to Acacia sect. Acacia and are allopatric with respect to their closest relatives (A. acuaria W.Fitzg. and A. glutinosissima Maiden & Blakely respectively) which are reasonably widespread in the central and northern wheatbelt region of the South West Botanical Province.
Miscellaneous new species of Acacia (Fabaceae: Mimosoideae) from south-west Western Australia
Six new species endemic to south-west Western Australia are described. Three of the species belong to Acacia Mill. sect. Acacia (formerly sect. Phyllodineae DC.), namely, A. adjutrices Maslin (based on A. insolita subsp. efoliolata Maslin), A. coatesii Maslin and A. thieleana Maslin, one from Acacia sect. Juliflorae (Benth.) Maiden & Betche, namely, A. collegialis Maslin and two from Acacia sect. Plurinerves (Benth.) Maiden & Betche, namely, A. besleyi Maslin and A. fraternalis Maslin. Three of the species have conservation value under Department of Parks and Wildlife Conservation Codes for Western Australian Flora, namely, A. adjutrices (Priority Three), A. besleyi (Priority One) and A. coatesii (Priority One).
Four new species of Acacia (Fabaceae: Mimosoideae) with fasciculate phyllodes from south-west Western Australia
Four new species of Acacia Mill. sect. Acacia are described, namely, A. dilloniorum Maslin, A. keigheryi Maslin, A. kulinensis Maslin and A. parkerae Maslin. Acacia keigheryi, A. parkerae and A. kulinensis occur in the wheatbelt region of the South West Botanical Province; the first two were previously treated as informal variants of A. lullfitziorum Maslin to which they are related, with the latter more distantly related to these species. Acacia dilloniorum occurs in the adjacent Eremaean Botanical Province, in the south-west extremity of the arid zone; it is most closely related to A. kochii W.Fitzg. ex Ewart & Jean White and is not especially close to the other three new species described here. All four new species are classified as Priority taxa under Department of Parks and Wildlife Conservation Codes for Western Australian Flora. Notes are provided (under A. parkerae) on A. scabra Benth., a poorly known entity of uncertain taxonomic status that is known only from its type.
Spartothamnella canescens (Lamiaceae: Chloantheae), a new species from Western and Central Australia, with notes on the status of S. sp. Helena & Aurora Range
THIELE, K.R. AND SHEPHERD, K.A., Nuytsia24: 177–185 (2014)
Morphological assessment of the informally named Spartothamnella sp. Helena & Aurora Range (P.G. Armstrong 155-109) shows it is not distinct from Western Australian populations of S. puberula (F.Muell.) Maiden & Betche. However, examination of S. puberula s. lat. shows that Western and Central Australian populations are morphologically distinct from typical populations in eastern Australia. Accordingly, S. canescens K.R.Thiele & K.A.Sheph. is newly described to accommodate these atypical populations. A revised description of S. puberula and a modified key for the genus are also provided.
Acacia mackenziei, a new species of Acacia section Lycopodiifoliae (Fabaceae: Mimosoideae) with conservation significance from the east Kimberley region in northern Western Australia
MASLIN, B.R. AND BARRETT, R.L., Nuytsia24: 187–192 (2014)
Studies of Acacia Mill. sect. Lycopodiifoliae Pedley have resulted in the recognition of a new species, A. mackenziei Maslin & R.L.Barrett, which is most closely related to A. anasilla A.S.George. The new species occurs in the east Kimberley region of Western Australia where it is restricted to a single sandstone range near Kununurra. Acacia mackenziei is classified as a Priority One taxon under Department of Parks and Wildlife Conservation Codes for Western Australian Flora.
Four new species of Acacia section Juliflorae (Fabaceae: Mimosoideae) from the arid zone in Western Australia
Four new species from Acacia Mill. sect. Juliflorae (Benth.) Maiden & Betche are described, namely, A. curryana Maslin, A. doreta Maslin, A. lapidosa Maslin and A. petricola Maslin. Apart from A. doreta which extends into the Northern Territory and South Australia these species are endemic in Western Australia. Three of the species have conservation value under Department of Parks and Wildlife Conservation Codes for Western Australian Flora, namely, A. curryana (Priority One), A. lapidosa (Priority One) and A. petricola (Priority Two).
Calandrinia butcherensis and C. rubrisabulosa (Portulacaceae), new species from the Midwest of Western Australia
Two new species of Calandrinia Kunth. sect. Pseudodianthoideae Poelln. are described: C. butcherensis Obbens and C. rubrisabulosa Obbens. Images of the taxa and a distribution map are provided.
