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., Nuytsia 24: 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., Nuytsia 24: 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.

HISLOP, M., Nuytsia 24: 71–93 (2014)

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., Nuytsia 24: 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.

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., Nuytsia 24: 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

MASLIN, B.R., Nuytsia 24: 131–138 (2014)

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

MASLIN, B.R., Nuytsia 24: 139–159 (2014)

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

MASLIN, B.R., Nuytsia 24: 161–175 (2014)

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., Nuytsia 24: 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., Nuytsia 24: 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

MASLIN, B.R., Nuytsia 24: 193–205 (2014)

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

OBBENS, F.J., Nuytsia 24: 207–214 (2014)

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.

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.

The scantily collected Corymbia punkapitiensis (Myrtaceae) is not distinct from the widespread arid-zone species C. aparrerinja
