Four new obligate seeder taxa of Eucalyptus series Rufispermae (Myrtaceae) from the transitional rainfall zone of south-western Australia

NICOLLE, D., Nuytsia 19 (1): 77–97 (2009)

Three new species are described, viz. E. vittata D.Nicolle, an obligate seeder previously confused with the respouter species E. sheathiana Maiden and also differing from the latter in the narrower adult leaves and smaller buds and fruits_; E. frenchiana _ D.Nicolle_,_ an obligate seeder from between Norseman and Hyden, previously confused with E. corrugata Luehm. but most closely related to E. pterocarpa C.A.Gardner ex P.J.Lang and differing from the latter in the smaller leaves, buds and fruits and the hemispherical opercula; and E. distuberosa D.Nicolle_,_ an obligate seeder previously confused with the respouter species E. pileata Blakely_._ Two subspecies are recognized in E. distuberosa, viz. subsp. distuberosa, of widespread but scattered distribution in the southern goldfields, and subsp. aerata D.Nicolle, restricted to Bronzite Ridge west of Norseman. A key to the obligate seeder taxa of E. ser_._ Rufispermae Maiden is provided.

NICOLLE, D. AND FRENCH, M.E., Nuytsia 19 (1): 99–105 (2009)

A new subspecies of Eucalyptus calycogona described, differing from the other three subspecies of E. calycogona by the waxy branchlets, buds and fruits, the generally broader, dull adult leaves which are bluish at least when new, the consistently elliptical to ovate seedling leaves, and the generally larger flower buds and fruits. The new ubspecies is distributed on the eastern edge of the central wheatbelt in Western Australia, to the north-west of the distribution of subsp. calycogona. A key to E. ser_. Heterostemones_ Benth., a map indicating the distribution of E. calycogona in Western Australia, and illustration of the holotype and habit of E. calycogona subsp. miracula D.Nicolle & M.E.French are included.

A conspectus of the genus Amaranthus (Amaranthaceae) in Australia

PALMER, J., Nuytsia 19 (1): 107–128 (2009)

A synopsis of the 26 Amaranthus species known to occur in Australia is presented. Amaranthus centralis J.Palmer & Mowatt and A. induratus C.A.Gardner ex J.Palmer & Mowatt are described as new; distribution maps and photographs of the type specimens are included for these new species. Amaranthus undulatus R.Br. is the earliest correct name for the taxon currently known as A. pallidiflorus F.Muell., and lectotypes are selected for A. clementii Domin, A. leptostachyus Benth., A. macrocarpus Benth. and A. mitchellii Benth. A key to all species in Australia is presented.

A reduced circumscription of Balaustion and description of the new genus Cheyniana (Myrtaceae: Chamelaucieae)

RYE, B.L., Nuytsia 19 (1): 129–148 (2009)

The myrtaceous genus Balaustion Hook. is reduced to its original monotypic circumscription. Balaustion s. str. is closely related to Tilophloia Trudgen & Rye ms., both genera having stamens in a single circular series, broad filaments, a very large placenta and seeds with a large concave hilum, but Balaustion is distinguished by its prostrate habit with adventitious roots, basifixed anthers and long tubular flowers adapted to pollination by birds. A second bird-pollinated species with elongated flowers, previously known as B. microphyllum C.A.Gardner, is transferred into the new genus Cheyniana Rye as C. microphylla (C.A.Gardner) Rye. Since the type material of this species is missing, it is lectotypified on the original illustration. Another large-flowered species, but with more spreading, apparently insect-pollinated flowers, is described as C. rhodella Rye & Trudgen. Cheyniana is related to also Oxymyrrhine Schauer, which it resembles in its very reduced anthers and narrow filaments, but differs in its large colourful petals and woody indehiscent fruit. Both of the small genera treated in this taxonomic revision belong to the tribe Chamelaucieae and are restricted to the south-west of Western Australia.

Reinstatement of the Western Australian genus Oxymyrrhine (Myrtaceae: Chamelaucieae) with three new species

RYE, B.L., Nuytsia 19 (1): 149–165 (2009)

The south-western Australian genus Oxymyrrhine Schauer is reinstated and the type species, previously known as Baeckea polyandra F. Muell., is restored to its earlier name of O. gracilis Schauer.A lectotype is selected for B. polyandra and three new species, Oxymyrrhine cordata Rye & Trudgen, O. coronata Rye & ; Trudgen and O. plicata Rye & Trudgen_,_ are described. These four species make up a group described here as Oxymyrrhine s. str. and are distinguished from other members of Oxymyrrhine s. lat. and from all other genera of tribe Chamelaucieae by the broad cavity in the summit of their fruit. Oxymyrrhine s. lat. includes a particularly difficult species complex, which will be revised at a later time.

Three new species of Tecticornia (Chenopodiaceae, subfamily Salicornioideae) identified through Salinity Action Plan surveys of the wheatbelt region, Western Australia

SHEPHERD, K.A. AND LYONS, M.N., Nuytsia 19 (1): 167–180 (2009)

A number of potentially new species have been discovered through ongoing Government surveys of the wheatbelt region of Western Australia. Three new samphires identified from collections made in saline areas during these surveys are described here: Tecticornia annelida K.A.Sheph. & M.Lyons, T. sparagosa K.A.Sheph. & M.Lyons and T. loriae K.A. Sheph. & M.Lyons. Distribution maps and illustrations of these new species are included.

Guichenotia anota and Guichenotia apetala (Lasiopetaleae: Byttneriaceae or Malvaceae s. lat.) a new and a revised species endemic to the Ravensthorpe Range, south-west Western Australia

WILKINS, C.F. AND WHITLOCK, B.A., Nuytsia 19 (1): 181–190 (2009)

Guichenotia anota C.F.Wilkins is described as new and Guichenotia apetala A.S.George is revised. Both are endemic to the Ravensthorpe Range in south-west Western Australia. Cladistic analyses of morphological characters, and chloroplast and nuclear DNA sequences (Wilkins & Whitlock in prep.) show these two species to be most closely related to each other, and more closely related to Lasiopetalum Sm. than to Guichenotia J. Gay. As both are priority species for conservation, in an area with developmental pressures from mining, they require urgent description and revision, and are included here in the latter genus until their generic placement is certain. Anatomical leaf data is presented.

A new species of Pultenaea (Mirbelieae: Fabaceae) from Kundip, Western Australia

WILKINS, C.F., ORTHIA, L.A. AND CRISP, M.D., Nuytsia 19 (1): 191–196 (2009)

A new species Pultenaea craigiana C.F.Wilkins, Orthia & Crisp is described. It has affinity to P. brachytropis Benth. This species is endemic to the south-west of Western Australia and is a priority species for conservation. Conservation notes and a distribution map are provided.

Recombination of subspecies in Trihaloragis (Haloragaceae)

MOODY, M.L., Nuytsia 19 (1): 197 (2009)

Moody and Les (2007) recognized the genus Trihaloragis consisting of the single species Trihaloragis hexandra (F.Muell.) M.L.Moody & D.H.Les. Recombination of the three subspecies of Haloragis hexandra was overlooked at the time. Here new combinations of the three subspecies are presented.

Clarification of recent combinations in the genus Dysphania (Chenopodiaceae)

SHEPHERD, K.A. AND WILSON, PAUL G., Nuytsia 19 (1): 198–199 (2009)

In a paper commenting on the generic status of the Chenopodiaceae, Wilson (1987) noted an affinity between the representatives of Chenopodium L. subg. Ambrosia A.J.Scott and the genus Dysphania R.Br., based on the presence of both septate and glandular hairs as well as similarities in leaf shape, leaf venation, inflorescence structure and seed orientation. Mosyakin and Clemants (2002) later came to a similar conclusion and reassigned the North American representatives (both endemic and naturalised) of Chenopodium subg. Ambrosia to Dysphania.

Lectotypification of ten Restionaceae species names from south-west Western Australia

BARRETT, R.L. AND BRIGGS, B.G., Nuytsia 19 (2): 203–209 (2009)

A lectotype is selected for ten names published in 1993 and 1996 by K. Dixon, K.A. Meney and J. Pate for species of Restionaceae in the genera Desmocladus Nees, Harperia W.Fitzg., Hypolaena R.Br., Lepidobolus Nees, Loxocarya R.Br., Onychosepalum Steud., Leptocarpus R.Br. and Restio Rottb. The relevant species originally named in Leptocarpus and Restio are now included in Meeboldina Suess. and Chordifex B.G.Briggs & L.A.S.Johnson respectively. Additional collections of the ten taxa involved are also cited.

New taxa in the Leucopogon gracilis group (Ericaceae: Styphelioideae: Styphelieae)

HISLOP, M., Nuytsia 19 (2): 211–228 (2009)

Three new taxa, Leucopogon paradoxus Hislop, L. tenuicaulis Hislop and L. elegans Sond. subsp. psorophyllus are described. The first two of these are illustrated and the distributions of all three are mapped. A key is provided for all Western Australian taxa currently referred to the informal, subgeneric Leucopogon gracilis Group (sensu Hislop & Chapman 2007). Lectotypes are designated for the following taxa: Leucopogon elegans Sond., L. gracilis R.Br., L. oppositifolius Sond. and L. oppositifolius var. pubescens Sond.

Grevillea tetragonoloba (Proteaceae: Grevilleoideae) recircumscribed, with notes on its typification and a new segregate species, Grevillea nivea, described

OLDE, PETER M. AND MARRIOTT, NEIL R., Nuytsia 19 (2): 229–243 (2009)

Grevillea nivea P.M.Olde & N.R.Marriott is the third species that we have segregated and described from Grevillea tetragonoloba Meisner sensu McGillivray. The type citation of Grevillea tetragonoloba is discussed and modified. Recognition of Grevillea nivea as distinct from Grevillea tetragonoloba requires a modified circumscription for the latter species, and a full, updated description is provided here. A key is provided enabling distinction from closely related species.

A new subspecies of Acacia pentadenia (Leguminosae: Mimosoideae) from south-western Australia

REID, J.E., WARDELL-JOHNSON, G. AND MASLIN, B.R., Nuytsia 19 (2): 245–252 (2009)

A previously recognised informal variant of Acacia pentadenia Lindl. is described following extensive field and herbarium studies focused on the forest region to the north-east of Walpole. The new subspecies, Acacia pentadenia subsp. syntoma, is most readily distinguished from subsp. pentadenia by a combination of morphological attributes, as well as habit , phenological and ecological differences. Field observations have shown the two subspecies to be occasionally sympatric. A key to the subspecies is provided together with a distribution map and comparative images.

A new species of Hakea (Proteaceae) from the Swan Coastal Plain, Western Australia

SHEPHERD, K.A. AND BARKER, R.M., Nuytsia 19 (2): 253–258 (2009)

Hakea oligoneura K.A.Sheph. & R.M.Barker,a new species described herein, is only known from a few populations less than 100 km from the Perth metropolitan area. A distribution map and images of this new species are included.

Thysanotus unicupensis (Laxmanniaceae), a new species discovered in Unicup Nature Reserve, south-west Western Australia

SIRISENA, U.M., MACFARLANE, T.D. AND CONRAN, J.G., Nuytsia 19 (2): 259–263 (2009)

Thysanotus unicupensis is described as a new species from south-west Western Australia. This species shows some affinities to T. chinensis, T. formosus and T.parviflorus and is apparently localised on lateritic soils in moderately sunny areas within Jarrah/ Marri (Eucalyptus marginata/Corymbia calophylla) woodlands. The key published in Flora of Australia (1987) is amended to include the new species.

A new circumscription for Lysinema ciliatum (Ericaceae: Styphelioideae: Epacrideae) and reinstatement of L. pentapetalum

THIELE, K.R., Nuytsia 19 (2): 265–275 (2009)

Lysinema ciliatum has long been regarded as a widespread and variable species. Occurring throughout much of the South-West Botanical Province of Western Australia on a variety of substrates, it is morphologically variable in foliar and floral characters, with up to eleven morphotypes informally recognised as putatively distinct taxa following a preliminary assessment in the early 1990s. Examination of material from throughout the species’ range shows that most of the currently recognised informal morphotypes comprise a single, variable species which cannot be adequately divided into taxa. A second, distinct species is restricted to the south coast of Western Australia, approximately between Albany and Esperance, with a disjunct outlier east of Perth. Comparison with types shows that the correct name for the widespread taxon is Lysinema pentapetalum R.Br., while the mostly southern-coastal taxon matches the type of L. ciliatum. Descriptions and distribution maps are provided for these taxa, and a key to all species of Lysinema provided.

Banksia recurvistylis (Proteaceae), a new species from Western Australia

THIELE, K.R., Nuytsia 19 (2): 277–281 (2009)

Banksia recurvistylis K.R.Thiele is described to accommodate anomalous populations previously referred to B. meganotia (A.S.George) A.R.Mast & K.R.Thiele. The new species differs from B. meganotia in its habit and flower and leaf dimensions, and is geographically disjunct. Both B. meganotia and B. recurvistylis have relatively restricted distributions and are of conservation significance.

Three new species of Hibbertia (Dilleniaceae) from Western Australia

THIELE, K.R., Nuytsia 19 (2): 283–293 (2009)

Three new species, Hibbertia leucocrossa K.R.Thiele, H. fasciculiflora K.R.Thiele and H. propinqua K.R.Thiele are described as new. All taxa occur north of Perth in the Lesueur Sandplains subregion of the Geraldton Sandplains bioregion in the South West Botanical Province, Western Australia. A revision of a key to the Hibbertia species of Western Australia is provided.

A new, rare Marianthus (Pittosporaceae) from the Bremer Range in Western Australia

WEGE, J.A. AND GIBSON, N., Nuytsia 19 (2): 295–302 (2009)

Marianthus aquilonaris N.Gibson & Wege, a new species allied to M. mollis (E.M.Benn.) L.Cayzer & Crisp, is described. Morphometric analysis shows that it is most readily differentiated from M. mollis by its higher leaf L:W ratio, higher petal L:W ratio and longer petioles. Other distinguishing features include a more erect habit, smooth and more or less glabrous leaves with attenuate rather than rounded bases , fewer pilose hairs on the stems, peduncles and fruit, and paler petals. Descriptions of both taxa are provided and include the first record of glandular trichomes for the genus. Marianthus aquilonaris is endemic to the Bremer Range and potentially threatened by mining-related activities. It is gazetted as Declared Rare Flora in Western Australia under the name M. sp. Bremer (N. Gibson & M. Lyons 1776).

Two new species of Hibbertia (Dilleniaceae) from near Ravensthorpe in Western Australia

WEGE, J.A. AND THIELE, K.R., Nuytsia 19 (2): 303–310 (2009)

Two new and geographically restricted species allied to H. hamulosa J.R.Wheeler and H. mucronata (Turcz.) Benth. are newly described. Hibbertia abyssa Wege & K.R.Thiele is distinctive for its long, slender and more or less glabrous peduncles, and sepals with both uncinate and minute stellate hairs on the outer surface. This species, which occurs on shallow soils with siltstone outcropping, is known from a single population adjacent to the nickel mine on Bandalup Hill and has recently been gazetted as Declared Rare Flora. Hibbertia atrichosepala Wege & K.R.Thiele is readily distinguished from allied species by its completely glabrous sepals. It is a narrow range endemic of rocky, lateritic habitats in in the Ravensthorpe Range and is listed as having Priority One conservation status.

Ptilotus luteolus, a new combination in Ptilotus (Amaranthaceae)

DAVIS, R.W., Nuytsia 19 (2): 311–312 (2009)

Benl has been the most prominent recent author on the genus Ptilotus R.Br., and described a number of infraspecific taxa from a small amount of material. Many new collections have now been made and it has become apparent that the ranking of these taxa is in need of review. After infraspecific taxa in Ptilotus astrolasius F.Muell. were examined it became apparent that Ptilotus astrolasius var. luteolus Benl & H.Eichler warrants the rank of species.

An interim key to the Western Australian tribes and genera of Myrtaceae

RYE, B.L., Nuytsia 19 (2): 313–323 (2009)

As an interim measure to permit identification of Western Australian genera, a status quo key is presented here. At the same time the opportunity is taken to key out the ten tribes represented in Western Australia.
