An annotated census of the mosses of the Perth Region, Western Australia

BIGGS, L.J. AND CHAPPILL, J.A., Nuytsia 18: 1–30 (2008)

A census of the moss species of the Perth Region is based on field studies and collections housed at the Western Australia Herbarium (PERTH). It includes 83 taxa in 45 genera and 21 families. The largest families recorded were Pottiaceae and Bryaceae. Two species not previously recorded for Western Australia, Leptobryum pyriforme (Hedw.) Wilson and Pohlia nutans (Hedw.) Lindb., are included.

Platytheca anasima (Elaeocarpaceae) a new, geographically restricted species from the Whicher Range, south-west Western Australia

BUTCHER, R., Nuytsia 18: 31–37 (2008)

Platytheca anasima R.Butcher is described as a new species restricted to the Whicher Range of south-west Western Australia and distinguished from other Platytheca taxa. A distribution map and images of the new species are provided.

Rediscovery of Tetratheca nuda var. spartea (Elaeocarpaceae) in south-west Western Australia and elevation to specific rank as Tetratheca spartea

BUTCHER, R., Nuytsia 18: 39–47 (2008)

Tetratheca nuda Lindl. var. spartea Planch. ex Benth. was named by Bentham in 1863 from material collected from an unspecified locality by Drummond in 1843. Mueller placed the name in synonymy under T. virgata Steetz in 1882, but Thompson recognised and lectotypified the name in 1976, reiterating the close affinity with T. nuda but querying the status of the taxon. The taxon was known only from the type material until a 2005 collection from near Toodyay was confirmed as comparable with the type. Additional collections have since confirmed its distinctness from T. nuda. This taxon is described in full herein as T. spartea (Benth.) R.Butcher. Images of the new species and a distribution map are provided, as is an amended taxonomic key to the species of ‘leafless’ Tetratheca in Western Australia.

Atriplex eremitis (Chenopodiaceae), a new species from northern Western Australia

CRANFIELD, R.J., Nuytsia 18: 49–52 (2008)

A new saltbush species from the Pilbara region of Western Australia, Atriplex eremitis Cranfield, is described and mapped. Comparisons are made to the presumed closest species, A. cinerea Poir. and A. amnicola Paul G.Wilson, and an amendment to the key to Atriplex species in Flora of Australia is provided.

Further new taxa in Banksia (Proteaceae: Grevilleoideae)

GEORGE, A.S., Nuytsia 18: 53–59 (2008)

Three new taxa are described: Banksia ashbyi Baker f. subsp. boreoscaia A.S.George, B. incana A.S.George var. brachyphylla A.S.George and B. sphaerocarpa R.Br. var. pumilio A.S.George. The taxon described as B. sphaerocarpa var. latifolia F.Muell. ex Benth. (1870) and later placed in synonymy under var. sphaerocarpa has recently been rediscovered and is again recognised as an accepted taxon.

Three new species of Leucopogon (Ericaceae: Styphelioideae: Styphelieae) from the far south-west of Western Australia

HISLOP, M., Nuytsia 18: 61–78 (2008)

Two new species, Leucopogon altissimus Hislop and L. wheelerae Hislop, are described. A third taxon, L. richei (Labill.) R.Br. var. acutifolius Benth., is elevated to species level under a new name, L. interstans Hislop, and with an expanded circumscription. All three are illustrated and their distributions mapped. Full descriptions of the species L. alternifolius R.Br. and L. australis R.Br., which are morphologically similar to L. wheelerae and L. interstans respectively, are given for purposes of comparison. Lectotypes are designated for the following taxa: L. alternifolius R.Br., L. australis R.Br., L. interruptus R.Br., L. paniculatus Sond., L. polystachyus R.Br. and L. polystachyus var. serratifolius Sond.

A new species of Rorippa (Brassicaceae) from southern Western Australia

KEIGHERY, G.J., Nuytsia 18: 79–82 (2008)

The Western Australian populations of Rorippa dictyosperma (Hook.) L.A.S.Johnson are segregated as a new species, R. cygnorum Keighery sp. nov.

Elucidation of Olearia species related to O. paucidentata (Asteraceae: Astereae)

LANDER, N.S., Nuytsia 18: 83–95 (2008)

A group of south-west Western Australian endemic species related to Olearia paucidentata (Steetz) F.Muell. ex Benth. are distinguished, and an identification key and comprehensive descriptions of each are presented. O. paucidentata is lectotypified. Eurybia lehmanniana Steetz is re-instated at specific rank as Olearia lehmanniana (Steetz) Lander. Maps and notes on typification, distributions, etc. of each species are provided.

New species of Olearia (Asteraceae: Astereae) from Western Australia

LANDER, N.S., Nuytsia 18: 97–106 (2008)

Two new species of Olearia Moench endemic to the Mallee and Coolgardie Bioregions respectively in the South-West Botanical Province of Western Australia are described: O. newbeyi Lander and O. trifurcata Lander. Olearia pimeleoides subsp. incana D.A.Cooke, widely distributed across southern Australia, is formally raised to specific rank. Descriptions, distribution maps, illustrations, and notes on affinities, habitat and conservation status are provided for all three species.

A review of Acacia coolgardiensis (Leguminosae: Mimosoideae) and closely related species in Western Australia

MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 107–125 (2008)

The three subspecies formerly comprising the widespread, variable, Western Australian species Acacia coolgardiensis Maiden are now treated as distinct species, namely, A. coolgardiensis, A. effusifolia Maslin & Buscumb (syn. A. coolgardiensis subsp. effusa R.S.Cowan & Maslin) and A. latior (R.S.Cowan & Maslin) Maslin & Buscumb (syn. A. coolgardiensis subsp. latior R.S.Cowan & Maslin). Two new related species are also described, A. incognita Maslin & Buscumb which was formerly confounded with A. coolgardiensis subsp. coolgardiensis, and the recently discovered A. sulcaticaulis Maslin & Buscumb which is listed as a Priority One species according to the Department of Environment and Conservation’s (DEC) Conservation Codes for Western Australian Flora. A key to the recognition of these five species is presented.

Acacia diallaga (Leguminosae: Mimosoideae), a new geographically restricted species with diallagous phyllodes from the Midwest Region of south-west Western Australia

MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 127–132 (2008)

Acacia diallaga Maslin & Buscumb, a new species of Acacia sect.Juliflorae (Benth.) C.Moore & Betche restricted to a small area east of Morawa in the Midwest Region of Western Australia is described. A feature of the new species (and one from which the botanical name is derived) is that during times of drought the phyllodes turn a purplish colour, reverting to their normal glaucous to sub-glaucous colour when conditions improve. This process of foliage colour change related to weather conditions occurs also in A. subsessilis A.R.Chapman & Maslin which is the closest relative of A. diallaga. The new species is listed as a Priority Two species according to the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.

Acacia umbraculiformis (Leguminosae: Mimosoideae), a new species related to A. quadrimarginea from the Midwest Region of south-west Western Australia

MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 133–138 (2008)

A new species common in the Midwest Region of Western Australia, Acacia umbraculiformis Maslin & Buscumb, is described and assigned to Acacia sect. Juliflorae (Benth.) C.Moore & Betche. Until recently this species had been confounded with A. quadrimarginea F.Muell.

New taxa of Acacia (Leguminosae: Mimosoideae) and notes on other species from the Pilbara and adjacent desert regions of Western Australia

MASLIN, B.R. AND VAN LEEUWEN, S., Nuytsia 18: 139–188 (2008)

Preparatory to publishing books on the Acacia Mill. flora of the Pilbara region, 10 new species (A. bromilowiana Maslin, A. fecunda Maslin, A. leeuweniana Maslin, A. minutissima Maslin, A. subcontorta Maslin, A. subtiliformis Maslin, A. trudgeniana Maslin, A. robeorum Maslin, A. thoma Maslin and A. walkeri Maslin) and two new subspecies (A. catenulata C.T.White subsp. occidentalis Maslin and A. steedmanii Maiden & Blakely subsp. borealis Maslin) are described. Acacia coriacea DC. is now more narrowly circumscribed to include subsp. coriacea and subsp. pendens R.S.Cowan & Maslin only, while the former A. coriacea subsp. sericophylla (F.Muell.) R.S.Cowan & Maslin has been reinstated as a distinct species (A. sericophylla F. Muell.). Notes on the variation in Western Australian plants of A. drepanocarpa F.Muell. are provided. Acacia bromilowiana, A. fecunda and A. subtiliformis are Priority Three taxa and A. leeuweniana is a Priority One taxon according to the Department of Environment and Conservation’s Conservation Codes for the Western Australian Flora.

An updated diagnosis for Eucalyptus series Accedentes (Myrtaceae) and a new mallee species for the series occurring in far western Australia

NICOLLE, D. AND BROOKER, M.I.H., Nuytsia 18: 189–196 (2008)

Eucalyptus L'Hér. ser. Accedentes Chippend. is diagnosed by an exclusive combination of characters for the first time. The series consists of nine species, all but one of which are endemic to Western Australia, including the newly described Eucalyptus baiophylla D.Nicolle & Brooker, a mallee occurring between Exmouth and Carnarvon on the west coast of Australia. The new species was formerly included in E. prominens Brooker and is most closely related to E. zopherophloia Brooker & Hopper. A key to the series is included and a map and illustrations of the new species are provided.

A revision of Eucalyptus ser. Cornutae subser. Conjunctae (Myrtaceae) from the south coast of Western Australia, including the description of four new taxa and comments on the hybrid origin of E. bennettiae

NICOLLE, D., FRENCH, M.E. AND MCQUOID, N.K., Nuytsia 18: 197–222 (2008)

Eight terminal taxa are recognised in Eucalyptus L’Hér. ser. Cornutae (Benth.) Brooker subser. Conjunctae Brooker. Two new species are described, viz., E. sinuosa D.Nicolle, M.E.French & McQuoid, known from only a few populations in the Corackerup Creek area and in Fitzgerald River National Park, and E. retusa D.Nicolle, M.E.French & McQuoid, known from one or possibly two populations from near Bremer Bay. New subspecies described are E. lehmannii (Schauer) Benth. subsp. parallela D.Nicolle & M.E.French, which is the widespread variant of the species, occurring from the Stirling Range area eastwards to Cape Arid, and E. conferruminata D.Carr & S.Carr subsp. recherche D.Nicolle & M.E.French, the eastern variant of that species apparently endemic to the Recherche Archipelago and the common variant in cultivation across southern Australia. The distribution of E. arborella Brooker & Hopper is modified with the discovery of a new population and the exclusion of another population included in this species by others. The hybrid status of E. bennettiae D.Carr & S.Carr is discussed. A key to E. subser. Conjunctae is provided.

Recognition of new taxa in Grevillea (Proteaceae: Grevilleoideae) from south-west Western Australia

OLDE, PETER M. AND MARRIOTT, NEIL R., Nuytsia 18: 223–234 (2008)

In this paper we recognise one new Grevillea species, Grevillea hislopii P.M.Olde & N.R.Marriott and two new subspecies, Grevillea althoferorum P.M.Olde & N.R.Marriott subsp. fragilis P.M.Olde & N.R.Marriott and Grevillea bracteosa C.F.Meisn. subsp. howatharra P.M.Olde & N.R.Marriott. All taxa occur in south-west Western Australia. Morphological analysis suggests that the taxa are not closely related. Interspecific and intraspecific keys are provided and affinities are discussed where relevant. Some of the taxa have a conservation priority and Conservation Codes are provided in all cases.

Seorsus, a new Gondwanan genus of Myrtaceae with a disjunct distribution in Borneo and Australia

RYE, B.L. AND TRUDGEN, MALCOLM E., Nuytsia 18: 235–257 (2008)

The new genus Seorsus Rye & Trudgen (Myrtaceae tribe Chamelaucieae) has four species, two in Borneo and one each in the north of the Northern Territory and the south-west of Western Australia. Seorsus is distinguished from related genera by the shape of its anther connective, the orientation of its anther loculi and its distinctly facetted seeds. Two of its four species were previously placed in Astartea DC., a third in Baeckea L. and the fourth is the new species Seorsus aequatorius Rye & Trudgen. Three new combinations, S. clavifolius (C.A.Gardner) Rye & Trudgen, S. intratropicus (F.Muell.) Rye & Trudgen and S. taxifolius (Merr.) Rye & Trudgen, are made. The morphological characteristics, Gondwanan distribution and relationships of the new genus are discussed. Descriptions, keys, illustrations and distribution maps are provided.

Tecticornia papillata (Chenopodiaceae: Salicornioideae), a new andromonoecious samphire from near the Carnarvon Range, Western Australia

SHEPHERD, K.A., Nuytsia 18: 259–266 (2008)

Tecticornia papillata K.A.Sheph., described here as new, has an unusual fruit structure previously only observed in T. disarticulata (Paul G.Wilson) K.A.Sheph. & Paul G.Wilson. It differs from this species in having vegetative articles and bracts with strongly fimbriate margins and caudate apices, and a distinctly papillate epidermis for which the species is named. As this new species has a restricted distribution it has a Priority One conservation status. A distribution map and images of the species are presented. In addition, the molecular and morphological diversity within T. disarticulata is discussed.

New combinations in the genus Dysphania (Chenopodiaceae)

SHEPHERD, K.A. AND WILSON, PAUL G., Nuytsia 18: 267–272 (2008)

A long standing recognition of a possible affinity between Dysphania R.Br. and Chenopodium L. subg. Ambrosia A.J.Scott has been corroborated by molecular phylogenetic evidence. While the North American species of C. subg. Ambrosia have been transferred to Dysphania this has not occurred elsewhere. In light of this, new combinations are made here for the Australian and New Zealand species of C. subg. Ambrosia. A key to the Australian species of Dysphania is provided.

Pilostyles coccoidea (Apodanthaceae), a new species from Western Australia described from morphological and molecular evidence

THIELE, K.R., WYLIE, S.J., MACCARONE, L. AND HOLLICK, P., Nuytsia 18: 273–284 (2008)

Pilostyles coccoidea K.R.Thiele, a new species of holoparasitic flowering plant found on the legume genus Jacksonia R.Br. ex Sm., is described and illustrated. The new species is related to P. collina Dell and P. hamiltonii C.A.Gardner, both also from south-western Western Australia but growing on different hosts. The three species differ in morphological features of flowers and fruits. In addition, analysis of nad1, 16S and matR gene sequences confirms the distinctness of P. coccoidea from P. hamiltonii. Pilostyles coccoidea appears to be a relatively common species within its restricted range of distribution between Eneabba and the Moore River, north of Perth.

Stylidium perplexum (Stylidiaceae): a remarkable new triggerplant from south-west Western Australia

WEGE, J.A., Nuytsia 18: 285–289 (2008)

Stylidium perplexum Wege is newly described and photographs and a distribution map provided. This distinctive triggerplant has a tuberous, multi-stemmed and somewhat shrubby habit, discoid glandular trichomes restricted to the pedicels and hypanthia, linear leaves to 2 cm long, an elliptic hypanthium, narrow calyx lobes, and white to purplish laterally-paired corolla lobes bearing eight purple-tipped throat appendages. It occurs within a Conservation Park south-east of Dardanup and is listed as having conservation priority in Western Australia.

A new subspecies of Gnaphalium indutum (Asteraceae: Gnaphalieae)

WILSON, PAUL G., Nuytsia 18: 291–293 (2008)

Gnaphalium indutum Hook.f. is considered to consist of two infraspecific taxa, subsp. indutum and subsp. acuminatum Paul G.Wilson subsp. nov. The latter is predominantly an inland taxon of non-saline habitats.

Coronidium, a new Australian genus in the Gnaphalieae (Asteraceae)

WILSON, PAUL G., Nuytsia 18: 295–329 (2008)

The genus Coronidium Paul G.Wilson, a segregate of Helichrysum Mill. sensu lato, is described. It consists of 17 species, all of which are found in eastern Australia while two are also present in South Australia and one in Tasmania. Six species and two subspecies are described as new: C. cymosum Paul G.Wilson, C. elatum (A.Cunn. ex DC.) Paul G.Wilson subsp. minus Paul G.Wilson, C. elatum subsp. vellerosum Paul G.Wilson, C. flavum Paul G.Wilson, C. fulvidum Paul G.Wilson, C. lanosum Paul G.Wilson, C. kaputaricum Paul G.Wilson, and C. telfordii Paul G.Wilson, while Helichrysum adenophorum var. waddelliae J.H.Willis is raised to species rank as C. waddelliae (J.H.Willis) Paul G.Wilson; a further ten species are transfers from Helichrysum: C. oxylepis (F.Muell.) Paul G.Wilson, C. rupicola (DC.) Paul G.Wilson, C. glutinosum (Hook.) Paul G.Wilson, C. lanuginosum (A.Cunn. ex DC.) Paul G.Wilson, C. newcastlianum (Domin) Paul G.Wilson, C. boormanii (Maiden & Betche) Paul G.Wilson, C. elatum (DC.) Paul G.Wilson, C. lindsayanum (Domin) Paul G.Wilson, C. adenophorum (F.Muell.) Paul G Wilson, and C. scorpioides (Labill.) Paul G.Wilson. Several names are lectotypified.

Notes on the genus _Chrysocephalum (_Angianthinae: Asteraceae) with the description of one new species from Western Australia, and a new combination

WILSON, PAUL G., Nuytsia 18: 331–338 (2008)

The probability of the genus Chrysocephalum being paraphyletic is reviewed. Helichrysum gilesii F.Muell. is transferred to Chrysocephalum. A new species from the Gibson Desert, Western Australia is described and is compared with its close relative C. gilesii (F.Muell.) Paul G.Wilson. A widespread taxon from southern Australia which has been variously referred to as Chrysocephalum apiculatum (Labill.) Steetz or C. aff. apiculatum is shown to be C. vitellinum Sond.; this name is lectotypified. A key to the species of Chrysocephalum found in Western Australia is provided.

Lepidosperma amansiferrum is an orthographic error of L. amantiferrum

BARRETT, R.L., Nuytsia 18: 339 (2008)

The name Lepidosperma amansiferrum R.L.Barrett was recently published for a new species restricted to banded ironstone formations in the southern Goldfields of Western Australia (Barrett 2007). Karen Wilson and Peter Wilson (both Royal Botanic Gardens Sydney) recently drew my attention to an error in the way the Latin words were combined to form this name. Constructed from the Latin words amans (loving) and ferrum (iron), the word amans, when combined with ferrum, should be declined to amanti- (Stearn 1992).

Kennedia lateritia, a new name for Kennedia macrophylla (Fabaceae)

LALLY, T.R. AND WILSON, PAUL G., Nuytsia 18: 340–341 (2008)

The plant currently referred to as Kennedia macrophylla (Meisn.) Benth. is a twining or scrambling shrub with a very restricted distribution in the far south-west of Western Australia. It is listed as Declared Rare Flora under the Western Australian Wildlife Conservation Act 1950 and is endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (DEWHA 2007). In contrast to its rarity in nature, this taxon is widely cultivated in temperate Australia (Jones & Gray 1977; Elliot & Jones 1993). In view of the horticultural and conservation significance of this species, a necessary change to its nomenclature is presented here in advance of a revision of the subtribe Kennediinae currently in preparation by the first author.
