Dedication - Dr Jennifer Anne (Jenny) Chappill, 1959–2006

LEMSON, K.L., Nuytsia 16 (1): 1–2 (2006)

We dedicate this issue of NUYTSIA to the memory of our friend and colleague, Jennifer Anne Chappill. Jenny made significant contributions to both our knowledge of the Western Australian flora and to the local systematics community, and it is fitting that she be honoured in this way.

Coprinopsis stangliana - a recently introduced fungus expanding in urban bushlands of the Perth region of Western Australia

BOUGHER, N.L., Nuytsia 16 (1): 3–10 (2006)

Successively for the past ten years a distinctive, large fungus superficially resembling the northern hemisphere Magpie Fungus Coprinopsis picacea syn. Coprinus picaceus has been observed for the first time in Western Australia (WA). The fungus is a member of the section Coprinus subsection Alachuani. Based on morphological and habitat attributes, the WA fungus is considered in this paper to be affiliated with Coprinopsis stangliana syn. Coprinus stanglianus. C. stangliana is known from calcareous soil, limestone, and chalk in Europe and Turkey, but has not been confirmed in Australia. In WA, C. stangliana generally has larger fruit bodies than reported for this species elsewhere. The fungus produces abundant fruit bodies in highly disturbed patches within numerous urban bushlands of the Perth region. The apparent recent establishment of such a conspicuous fungus, and observations of its fruiting patterns over successive years suggest that it is rapidly spreading following a relatively recent introduction into the Perth region.

Logania wendyae (Loganiaceae), a new species from south-west Western Australia

CRANFIELD, R.J. AND KEIGHERY, G.J., Nuytsia 16 (1): 11–14 (2006)

Logania wendyae Cranfield & Keighery, a new species endemic to the Jarrah Forest bioregion of south-western Western Australia is described, illustrated and mapped.

Boronia barrettiorum (Boronia subseries Filicifoliae: Rutaceae), a new species from the Kimberley Region of north-western Australia

DURETTO, M.F., Nuytsia 16 (1): 15–20 (2006)

Boronia barrettiorum Duretto sp. nov. (Boronia subseries Filicifoliae: Rutaceae) is described and its relationships discussed. Variation in B. pauciflora W.Fitz. is also discussed and a key to the species of Boronia found in the Kimberley Region is provided.

Reinstatement of Patersonia occidentalis var. angustifolia and Patersonia occidentalis var. latifolia (Iridaceae)

GIBSON, N., Nuytsia 16 (1): 21–27 (2006)

Patersonia occidentalis R.Br. var. angustifolia Benth. and Patersonia occidentalis R.Br. var. latifolia (F.Muell.)Benth. are reinstated and a lectotype for P. occidentalis var. angustifolia is selected. Both P. occidentalis var. angustifolia and P. occidentalis var. latifolia are endemic to south-west Western Australia. P. occidentalis var. angustifolia occurs along drainage lines and in seasonal swamps while P. occidentalis var. latifolia occurs in drier habitats generally on clays or loams associated with laterite, granite or sandstone. The three varieties can be separated using a combination of leaf width, scape length and leaf aspect ratio.

Contributions to Western Australian orchidology: 3. New and reinstated taxa in Eriochilus

HOPPER, STEPHEN D. AND BROWN, A.P., Nuytsia 16 (1): 29–61 (2006)

The systematics of Western Australian members of Brown’s (1810) genus Eriochilus R.Br. has been controversial, confused and poorly understood. This paper provides a revision drawing upon recent fieldwork, collections and herbarium studies that considerably resolve the taxonomic situation. We describe the following taxa as new: E. helonomos, E. pulchellus, E. valens, E. dilatatus subsp. magnus, E. dilatatus subsp. orientalis, E. dilatatus subsp. undulatus, and E. scaber subsp. orbifolia. New combinations are E. dilatatus Lindley subsp. multiflorus (Lindley) Hopper and A.P. Br. and E. dilatatus Lindley subsp. brevifolius (Benth.) Hopper and A.P. Br. The genus is thus enlarged in Western Australia to 6 species. E. dilatatus is geographically variable, now with six subspecies. E. scaber subsp. orbifolia is the only threatened taxon in Western Australia, known from a single locality near Walpole.

New species of Xanthoria (Teloschistaceae) from Australia

KONDRATYUK, S.Y., KÄRNEFELT, E.I. AND THELL, A., Nuytsia 16 (1): 63–76 (2006)

Xanthoria elixii S. Kondr. & Kärnefelt, sp. nov. and X. streimannii S. Kondr. & Kärnefelt, sp. nov. are described, illustrated and compared with allied taxa, and a detailed description of the common and widespread species X. filsonii Elix is also given. A key to Australian taxa of Xanthoria is provided.

A new species of Tribonanthes (Haemodoraceae) from saline wetland margins in Western Australia

LYONS, M.N. AND KEIGHERY, G.J., Nuytsia 16 (1): 77–80 (2006)

A new species, Tribonanthes minor, is described and illustrated. The new species is confined to the sandy margins of primary saline lake systems in southern Western Australia.

Acacia splendens (Leguminosae : Mimosoideae), a new rare species from near Dandaragan, Western Australia

MASLIN, B.R. AND ELLIOTT, C.P., Nuytsia 16 (1): 81–86 (2006)

A new species, Acacia splendens Maslin & C.P. Elliott, is described and illustrated. It is most closely related to A. microbotrya Benth. and A. daphnifolia Meisn. and is geographically restricted to near Dandaragan, Western Australia. Acacia splendens is Declared Rare Flora (ranked as Endangered) under the Western Australian Wildlife Conservation Act 1950 and is also listed as Endangered under Commonwealth legislation.

Formal recognition of Eucalyptus platydisca (Myrtaceae), an arid-zone monocalypt from south-western Australia

NICOLLE, D. AND BROOKER, M.I.H., Nuytsia 16 (1): 87–94 (2006)

The new species Eucalyptus platydisca is formally described, the species having been long recognised as a distinct taxon under the manuscript name E. platydisca and under various phrase names including the common name Jimberlana mallee. The new species is known from just two populations near Norseman in Western Australia and is included in Western Australia’s Schedule of Declared Rare (Endangered) Flora. The new species is closely related to, but readily distinguishable from, E. diversifolia, differing in the narrower juvenile leaves, the consistently 7-flowered inflorescences, the longer, conical to horn-shaped operculum, the broader fruits with a consistently broad disc and the granite hill habitat. Eucalyptus platydisca is probably a relictual species and occurs in the lowest rainfall environment of any monocalypt (Eucalyptus subgenus Eucalyptus). The new species is part of E. subser. Neuropterae, and a key for the subseries is presented.

A review of the tuberous Calandrinia species (section Tuberosae), including three new species for Western Australia

OBBENS, F.J., Nuytsia 16 (1): 95–115 (2006)

Background on the current systematic status of Australian Calandrinia is explained. Three new species of section Tuberosae von Poellnitz are described and illustrated: Calandrinia crispisepala Obbens, C. kalanniensis Obbens and C. translucens Obbens. A key to section Tuberosae is provided. Additional descriptive material for the previously named species is provided along with notes that explain the important differences and similarities between the six species now belonging to this section.

A partial revision of the south-western Australian species of Micromyrtus (Myrtaceae: Chamelaucieae)

RYE, B.L., Nuytsia 16 (1): 117–147 (2006)

This partial revision of the genus Micromyrtus Benth., deals mainly with species that have a ten-ribbed hypanthium, but excludes the M. racemosa complex. All of the new species are endemic to the south-west of Western Australia. Eight taxa are named: M. acuta Rye, M. chrysodema Rye, M. clavata J.W. Green ex Rye, M. elobata subsp. scopula Rye, M. placoides Rye, M. navicularis Rye, M. redita Rye and M. triptycha Rye. A key is given for Western Australian members of the genus. Micromyrtus is compared with its close relative Corynanthera J.W. Green, and the morphological specialisations of both genera and their possible affinities to other genera in tribe Chamelaucieae are discussed. The compressed winged diaspore of Corynanthera, which has the peduncle fused to both the bracteoles and fruit, is of particular interest, and an illustration compares it with diaspores from five- and ten-ribbed species of Micromyrtus.

New combinations and lectotypifications for the south-western Australian genus Astartea (Myrtaceae)

RYE, B.L., Nuytsia 16 (1): 149–156 (2006)

Three new combinations, Astartea affinis (Endl.) Rye, A. arbuscula (Benth.) Rye and A. astarteoides (Benth.) Rye, are made for species that were initially described in the genus Baeckea L. Lectotypes are selected for two of the base names, Baeckea affinis Endl. (including its synonym Astartea endlicheriana Schauer nom. illeg.) and B. astarteoides Benth., and also for Astartea laricifolia Schauer.

Three new species of Lechenaultia (Goodeniaceae) from south-west Western Australia, and a new key to the genus

SAGE, L.W., Nuytsia 16 (1): 157–166 (2006)

The new species, Lechenaultia galactites L.W. Sage, L. magnifica L.W. Sage and L. hortii L.W. Sage are described and illustrated. All three species are known from the South West Botanical province of Western Australia and all have conservation priority. A new key to Lechenaultia is provided.

New taxa of Goodenia subgenus Goodenia section Caeruleae subsection Scaevolina (Goodeniaceae), from the Eremaean Botanical Province of Western Australia

SAGE, L.W. AND ALBRECHT, D.E., Nuytsia 16 (1): 167–174 (2006)

Goodenia hartiana L.W. Sage and G. azurea subsp. hesperia L.W. Sage & Albr. are described, illustrated and mapped with notes on the distribution, conservation status, habitat preferences and relationships to other taxa. Keys to distinguish the new taxa are also provided.

Lasiopetalum pterocarpum (Malvaceae s.l.: Lasiopetaleae), a new and and rare species from south-west Western Australia

SHEPHERD, K.A., BENNETT, ELEANOR M., WILKINS, C.F. AND SAGE, L.W., Nuytsia 16 (1): 175–181 (2006)

Lasiopetalum pterocarpum E.M. Benn. & K.A. Sheph. sp. nov. is described and illustrated. The distinct winged fruit, for which L. pterocarpum is named, is unique within Lasiopetaleae. Lasiopetalum pterocarpum is allied to L. floribundum, which shares a similar habit, large ovate leaves and loose dichasial inflorescences. It can be readily distinguished from L. floribundum by its discolorous and strongly-lobed leaves, the absence of glandular hairs on the peduncles, and its larger seeds. This species is known from only one population south of Perth and is classified as critically endangered.

Stylidium diplotrichum (Stylidiaceae): a new scale-leaved trigger plant from south-west Western Australia, with taxonomic and anatomical notes on allied species

WEGE, J.A., Nuytsia 16 (1): 183–197 (2006)

A new scale-leaved trigger plant with conservation priority, Stylidium diplotrichum Wege, is described and illustrated. Revised taxonomic descriptions and notes are also provided for the priority species S. pseudohirsutum Mildbr. and S. expeditionis Carlquist, and the more commonly occurring S. hirsutum R.Br. and S. crossocephalum F.Muell. Leaf anatomy data are provided for all species. The location of the stomata is shown to be taxonomically informative.

Reinstatement of Stylidium rigidulum (Stylidiaceae), with notes on the morphologically allied S. kalbarriense

WEGE, J.A., Nuytsia 16 (1): 199–206 (2006)

Stylidium macrocarpum (Benth.) F.L.Erickson & J.H.Willis and S. leptophyllum DC. var. glabrescens Mildbr. are placed into synonymy under S. rigidulum Sond. and a revised taxonomic description provided. A modified description is also provided for the morphologically allied S. kalbarriense Lowrie & Kenneally. A chromosome number of n = 13 is reported for S. kalbarriense, and a count of n = 11 confirmed for S. rigidulum. These species are noted to grow in sympatry east of Dongara. Both taxa are susceptible to infection by the rust Puccinia stylidii McAlpine.

Taxonomic notes on the locket trigger plants from Stylidium subgenus Tolypangium section Repentes

WEGE, J.A., Nuytsia 16 (1): 207–220 (2006)

Two new trigger plants from south-west Western Australia, Stylidium perula Wege and Stylidium thylax Wege, are described and illustrated. Revised descriptions are provided for the morphologically allied S. sacculatum F.L.Erickson & J.H.Willis and S. pseudosacculatum Lowrie, A.H. Burb. & Kenneally. Features of trichome structure are argued to provide important taxonomic characters at the species level in Stylidium. The morphology and function of the column cunabulum is explored.

Taxonomic observations on the Stylidium leptocalyx complex (Stylidiaceae)

WEGE, J.A., Nuytsia 16 (1): 221–231 (2006)

The name Stylidium leptocalyx Sond. has been misapplied for many years. This trigger plant is now recognised to be of restricted distribution in the wandoo country south-west of York, and is characterised by pink flowers with linear calyx lobes, arranged in a loose, corymb-like raceme. Stylidium stenosepalum E.Pritz. is reinstated to account for the northern sandplain entity previously known as S. leptocalyx. This species differs from S. leptocalyx in possessing white flowers with a longer corolla tube and column. Amended descriptions and floral images are provided for both species, along with the morphologically-allied S. scabridum Lindl.

Taxonomic observations on Stylidium spathulatum (Stylidiaceae), with the description of three allied species from section Saxifragoidea

WEGE, J.A., Nuytsia 16 (1): 233–246 (2006)

Stylidium spathulatum R.Br. (n=14) is lectotypified and a revised species description provided. On the basis of cytological and morphological evidence Stylidium planirosulum Wege (n=13) and S. glandulosissimum Wege (n=13) are described as new. A third morphologically allied species with conservation priority, Stylidium gloeophyllum Wege, is also described. Variation in trichome structure and distribution is shown to be highly diagnostic. Illustrations are provided for the three new species.

Stylidium hymenocraspedum (Stylidiaceae) - a new species for Western Australia, and the lectotypification of S. maitlandianum

WEGE, J.A., Nuytsia 16 (1): 247–253 (2006)

A new species of trigger plant with conservation priority, Stylidium hymenocraspedum Wege, is described and illustrated. The morphologically allied S. maitlandianum E.Pritz. is lectotypified and an amended taxonomic description provided.

Rhetinocarpha (Asteraceae : Gnaphalieae) - a new genus from Western Australia

WILSON, PAUL G. AND WILSON, M.A., Nuytsia 16 (1): 255–260 (2006)

Myriocephalus suffruticosus Benth. is transferred to a new genus Rhetinocarpha Paul G. Wilson & M.A. Wilson. One new species combination is made: R. suffruticosa (Benth.) Paul G. Wilson & M.A. Wilson.
