Two new species, Z. eichleri R.M. Barker and Z rowelliae R.M. Barker, are described from within the 5merous group of Zygophyllum species, together with a revised key to this group. Z. halophilum R.M. Barker, Z. reticulatum H. Eichler ex R.M. Barker and Z aurantiacum ssp. simplicifolium H. Eichler ex R.M. Barker are described from the group of species with 4-winged fruits and a revised key is also provided to this group. Z marliesiae R.M. Barker, closely related to Z. prismatothecum, is distinguished for the first time. Typifications and notes on other Australian species are also presented. Introduction An earlier paper (Barker 1996) documented some of the manuscript names of Hj. Eichler within the Zygophyllaceae of Australia. Many of these names were already in use since there were collections which had been annotated with them and Eichler had chosen and segregated types. The following paper continues to document new taxa within Zygophyllum. Z reticulatum and Z. aurantiacum ssp. sim...

Nuytsia—The journal of the Western Australian Herbarium
Mollemans, F.H. Drummondita wilsonii, Philotheca langei and P. basistyla (Rutaceae), new species from southwest Western Australia. Nuytsia 9(1): 95-109 (1993). One new species of Drummondita and two new species of Philotheca are described. All three taxa are apparently rare, each restricted to limited geographic areas. Drummondita wilsonii is similar to D. erieoides, but has unequal calyx segments in common with D. miniata. Philotheca langei and P. basistyla both have affinities with Eriostemon falcatus which is currently presumed extinct. Similarities between D. wilsonii, D. erieoides and D. miniata, pollination mechanisms and flower colour variation in Drummondita, distribution and flowering time of the D. erieoides group (which includes D. miniata and D. wilsonii) and the evolutionary history of the Drummondita erieoides group, D. hassellii group and D. calida are discussed. Additional collections were subsequently made by the author and the following descriptions are based on this material.
Cunninghamia, 2001
The ecology of Rutaceae species remains poorly understood, a pattern typical across Australia, with a few notable exceptions. There have been no comprehensive demographic studies of members of the family in Sydney, and only limited attempts to examine aspects of the biology of the species in the family. In particular, the seed biology and ecology of the family and the impact of fire on species are poorly understood. This review poses a number of questions for research on members of the Rutaceae.
Systematics of seagrasses (Zosteraceae) in Australia and New Zealand
Systematic Botany, 2002
Previous taxonomic treatments of the family Zosteraceae in Australia/New Zealand have recognized Heterozostera tasmanica (monotypic) and four Zostera species all belonging to subgenus Zosterella: Z. capricorni, Z. muelleri, Z. mucronata, Z. novazelandica. Zostera has always been taxonomically problematic in Australia, where researchers have expressed difficulty with species recognition due to vague or inconsistent morphological characters. There also has been a lack of agreement on generic (notably the distinctness of Heterozostera) and subgeneric delimitation. Recent anatomical, developmental, and molecular studies urge a reevaluation of relationships in the family. To clarify the taxonomy of Zosteraceae, we investigated interspecific phylogenetic relationships focusing on Australian species of subgenus Zosterella. We examined material comprising all genera of Zosteraceae (Heterozostera, Nanozostera, Phyllospadix, Zostera), six/seven species of Zostera subgenus Zosterella (including all Australian/New Zealand species), and one of four species of Zostera subgenus Zostera. We conducted phylogenetic analyses of morphological data and DNA sequences from nuclear (ITS) and plastid (trnK intron, rbcL) genomes. Our results indicate two major clades (highly divergent at both morphological and molecular levels) and two subclades (with low morphological and molecular divergence) within Zosteraceae. Little morphological and molecular variation was observed among representatives within the clade of Australian/New Zealand members of subgenus Zosterella, and none provided cladistic support for taxa recognized formerly as separate species. We recommend that Zosteraceae comprise two genera (Phyllospadix, Zostera) with the latter subdivided into three subgenera (Zostera, Zosterella, Heterozostera). Furthermore, Australian/New Zealand representatives of Zostera subgenus Zosterella should be merged within a single species (Z. capricorni) to reflect the inability of morphological or molecular data to effectively delimit additional species in this group.
Major Clades of Australasian Rutoideae (Rutaceae) Based on rbcL and atpB Sequences
PLoS ONE, 2013
Background: Rutaceae subfamily Rutoideae (46 genera, c. 660 species) is diverse in both rainforests and sclerophyll vegetation of Australasia. Australia and New Caledonia are centres of endemism with a number of genera and species distributed disjunctly between the two regions. Our aim was to generate a high-level molecular phylogeny for the Australasian Rutoideae and identify major clades as a framework for assessing morphological and biogeographic patterns and taxonomy.
Asterolasia beckersii (Rutaceae), a new species from the Northern Tablelands, New South Wales
Telopea
Asterolasia beckersii Orme & Duretto (Rutaceae) is newly described. The species is restricted to the Nundle area (Tamworth district) on the Northern Tablelands of New South Wales. The species is related to A. correifolia (A.Juss.) Benth. and A. hexapetala (A.Juss.) Druce and can be distinguished from these by leaf, inflorescence and floral characters. The ecology and conservation status of A. beckersii are discussed and a key to Asterolasia for eastern Australia is provided. Orme and Duretto Conservation status: In 2004, this species was determined to be Endangered under Schedule 1 of the New South Wales Threatened Species Conservation Act 1995; it is not listed under Federal legislation. Plants are known to occur in Tuggolo Creek and Back River Nature Reserves, Tuggolo State Forest and the area above Dungowan Dam which is managed by local government and under some protection as a water catchment area (Fig. 1). After visits to each of the three sites, the extent of each population was found to be small, and where population size data was recorded with herbarium specimens, it was noted to be between one and 20 individuals. Etymology: The epithet honours Doug Beckers (NSW National Parks and Wildlife officer) for discovering the species. Key to the species and subspecies of Asterolasia found in eastern Australia (SA, Vic., NSW, Qld) Note: Of the taxa found in eastern Australia only A. asteriscophora subsp. albiflora (E Vic.; couplet 6), A. muricata (SA; couplet 1), A. phebalioides (SA, W Vic.; couplet 13) do not occur in NSW. All Western Australian species have 1-4 carpels and a key to these species is provided by Wilson (2013). The couplets leading to the subspecies of A. trymalioides are based on the key of McDougall et al. (2016).
Phytotaxa, 2014
Possession of hooked, distinctively discolorous styles, a broadly flabellate common bract subtending each flower pair, and a lignotuber place a putative new species, Banksia sp. Jervis Bay, in the B. spinulosa complex. Phenetic analysis of individuals from all named taxa in the B. spinulosa complex, including B. sp. Jervis Bay, based on leaf, floral, seed and bract characters support recognition of this species, which is described here as Banksia vincentia M.L.Stimpson & P.H.Weston. Known only from fourteen individuals, B. vincentia is distinguished by its semi-prostrate habit, with basally prostrate, distally ascending branches from the lignotuber, and distinctive perianth colouring. Its geographical location and ecological niche also separate it from its most similar congeners.
