A morphological study of herbarium and field-collected specimens, using phenetic techniques of agglomerative classification, ordination and minimum spanning trees, and covering the geographic range of the Holly Grevillea, G.�ilicifolia (R.Br.) R.Br. sensu lato, has resulted in the recognition of three species and four subspecies. The taxa are based on leaf form, noted by previous authors to be highly variable between populations. The taxa recognised here are G.�ilicifolia, G.�ilicifolia subsp. ilicifolia (typical, kite-shaped leaf form), G.�ilicifolia subsp. lobata (F.Muell.) T.L.Downing comb. et stat. nov. (oak-shaped leaf form), G.�dilatata (R.Br.) T.L.Downing comb. et stat. nov. (fan-shaped leaf form), G.�angustiloba (F.Muell.) T.L.Downing comb. et stat. nov., G.�angustiloba subsp. angustiloba (narrow-lobed leaf form) and G.�angustiloba subsp. wirregaensis T.L.Downing subsp. nov. (very narrow-lobed leaf form). The rank of subspecies is used where there are some intermediate plants between forms. Grevillea ilicifolia subsp. ilicifolia is the most widespread taxon and occurs in South Australia, western Victoria and in two localities in New South Wales. Grevillea angustiloba subsp. wirregaensis has the most restricted range, occurring in semi-arid regions near Wirrega in South Australia. Grevillea dilatata is largely endemic to Kangaroo Island, South Australia.

Phylogenetic and morphological analyses, male morphology, and hybrid crossing indicate that a population from Wardang Island, South Australia, is distinct from the monophyletic series of populations of Aedes (Halaedes) australis (Erichson) 1842 from Victoria, Tasmania, New South Wales, and New Zealand. The name Aedes (Halaedes) wardangensis has been assigned to the new species. Phylogenetic analysis of DNA sequences from the cytochrome oxidase II and internal transcribed spacer loci support the resurrection of Aedes (Halaedes) ashworthi Edwards, 1921 (Brust and Mahon, 1997). Aedes ashworthi is known only from Western Australia and was found to be infertile when crossed with Ae. wardangensis from South Australia and Ae. australis from New Zealand. The hybrid of Ae. australis from New South Wales × Ae. australis from New Zealand was fertile for three generations, documenting these as conspecific.

In south-eastern Australia banding of M. schreibersii has been concentrated in four areas: north-eastern New South Wales, south-eastern New South Wales, south-eastern Victoria, and south-western Victoria and south-eastern South Australia. The present paper analyses 2083 reported movements. Only 17 of these are from one of the four areas to another with the longest movement being 810 miles. Biologically and geographically separate populations of M. schreibersii are recognized in both north-eastern and south-eastern New South Wales. Each population has its basis in dependence upon a specific nursery site which is used annually by nearly all adult females in that population. Boundaries of population ranges in New South Wales are considered to be prominent features of physiography (i.e. divides). Bats move between population ranges less often than they move within population ranges. This cannot be explained solely in terms of the distances separating roosts. Available movement records from Victoria and South Australia are consistent with the pattern described for New South Wales. Two biologically recognizable populations (i.e, different birth periods) occur in south-western Victoria and south-eastern South Australia but these may have overlapping ranges. Only one nursery colony of M. schreibersii is known from south-eastern Victoria. On present evidence it remains possible that the apparent integrity of the population associated with this nursery is merely a consequence of distance from other areas of banding activity. Detailed analyses of movements in bats may provide direct evidence as to the kinds of cues by which a given species navigates. Thus the physiographic basis described for population ranges in New South Wales is consistent with the view that M. schreibersii may orientate to waterways or divides or both. The probability that there are area differences in the subtlety or nature of navigational cues is implied by the different physiographic circumstances of south-western Victoria and south-eastern South Australia. It is suggested that knowledge of population range boundaries may aid planning of meaningful homing experiments.

Silicified leaf impressions attributed to the tribe Banksieae (Proteaceae) are reported from a new Tertiary macroflora from near Glen Helen, Northern Territory and from the Miocene Stuart Creek macroflora, northern South Australia. The fossil leaf material is described and placed in Banksieaeformis Hill & Christophel. Banksieaeformis serratus sp. nov. is very similar in gross morphology to the extant Banksia baueri R.Br. and B. serrata L.f. and is therefore representative of a leaf type in Banksia that is widespread geographically and climatically within Australia and that is unknown in Dryandra or other genera of the Banksieae. The leaf material from Stuart Creek and Woomera represents the lobed leaf form typical of Paleogene macrofloras from southern Australia, but one species,B. langii sp. nov., is closely similar in gross form to Banksieaephyllum taylorii R.J.Carpenter, G.J.Jordan & R.S.Hill et al. from the Late Paleocene of New South Wales and similarly may be sclerophyllous. Also reported are impressions of Banksia infructescences, or ‘seed cones’, in Neogene sediments near Marree and Woomera, South Australia. These fossils demonstrate the presence of Banksiinae in central Australia in the mid-Tertiary, potentially indicating the former existence of linking corridors between now widely separated populations of Banksia.

Specimens of Phebalium glandulosum Hook. subsp. glandulosum representing the entire geographic range of the subspecies were examined for morphological and anatomical variation. Phenetic patterns were identified with the pattern analysis package PATN, and three distinct groups were identified. One group consists of plants from inland areas of New South Wales, north-western Victoria, and the Yorke and Eyre Peninsulas of South Australia; a second group consists of plants collected from alongside the Snowy River in eastern Victoria and south-eastern New South Wales; and a third group consists of plants from Queensland and northern New South Wales. The climate analysis program BIOCLIM was used to compare climate variables across the geographic range, and showed clear climatic separation in support of the phenetic analysis. The three groups are formally recognised here as distinct subspecies. Plants from Queensland and the Bourke region of northern New South Wales belong to the typical subspecies; plants from north-western Victoria, central New South Wales, and the Yorke and Eyre Peninsulas of South Australia form a cohesive assemblage and are recognised as a new subspecies P. glandulosum subsp. macrocalyx; and plants from the Snowy River in far eastern Victoria and the Southern Tablelands of New South Wales form a distinct and isolated group recognised as a new subspecies P. glandulosum subsp. riparium. These new subspecies are formally described, and an identification key and summaries distinguishing all six subspecies of P. glandulosum are presented.

THE pre Holocene-Late Pleistocene record of Phascolarctos in Australia is extremely meagre. There are at least two, possibly three extinct species of Phascolarctos in addition to the extant Phascolarctos cinereus (Black 1999). P. yorkensis (syn. Cundokoala yorkensis; Black and Archer 1997) is known from the Early Pliocene Curramulka Local Fauna, South Australia (SA), and the Late Pleistocene Wellington Caves Local Fauna, New South Wales (Archer et al. 1997; Pledge 1992). P. stirtoni occurs in the Late Pleistocene Cement Mills Local Fauna, Queensland, and is known only from a partial maxilla containing P3-M2 (Bartholomai 1968, 1977). Phascolarctos material from the mid- Pleistocene Victoria Fossil Cave and Spring Cave, Naracoorte, SA, have also been referred to P. cf. stirtoni but remain undescribed (Reed and Bourne 2000; Moriarty et al. 2000). P. maris is known from a single lower molar from the Early Pliocene Sunlands Local Fauna, SA (Pledge 1987). Black (1999) cast doubt on its validity, suggesting its features may fall within the intraspecific variation of P. stirtoni. If P. maris is referable to P. stirtoni it is another South Australian instance of this species, and extends its range back to the Early Pliocene. The new phascolarctid material documented here is from the early Pleistocene Nelson Bay Local Fauna, Portland, Victoria (141o 35? E; 38o 36? S). It is therefore an important additional southern occurrence of a species larger than the living P. cinereus, and is the only pre- Late Pleistocene record of the Phascolarctidae in Victoria.

The densities of red and grey kangaroos in western Victoria and south-eastern South Australia were assessed by aerial survey. Much of the 133000-km2 area surveyed was farmed intensively for wheat and sheep but a significant proportion was largely unaltered mallee woodland or mallee heath. Of the total area, 85% had a density of less than one kangaroo per square kilometre, and 32% had a density of less than 0.01 km-2, values considerably lower than those reported for pastoral areas in New South Wales and South Australia. Low densities in settled areas are attributed to intensive agricultural practices, small landholdings and lack of tree cover. Low densities in mallee may be due to the lack of palatable grasses and the absence of permanent watering points.

A New Species

Following a morphometric and cladistic analysis of the Daviesia ulicifolia Andrews group (Chandler and Crisp 1997), a new species, D. sejugata, is described. It occurs disjunctly in eastern Tasmania and southern Yorke Peninsula, South Australia, and is closely related to D. arthropoda F.Muell., differing in a generally more robust habit, thicker fleshy phyllodes, and larger flowers. Even with this species removed from D. ulicifolia, the latter varies considerably over a wide geographic, edaphic and altitudinal range. Daviesia ulicifolia is divided into six subspecies based on distinct phenetic and phylogenetic groups delimited in the earlier study. These are subsp. aridicola (glaucous plants in arid regions), subsp. incarnata (reddish-flowered plants in the Mt Lofty Range, South Australia), subsp. ruscifolia (plants with ovate-acuminate leaves and orange flowers in Victoria and southern New South Wales (NSW), often at high altitude), subsp. stenophylla (a narrow-leaved form in northern NSW and Queensland), subsp. pilligensis (ovate-leaved plants on sandy soil in western NSW), and subsp. ulicifolia (a paraphyletic residual from south-eastern states).

Morphological Differences

Anguina paludicola sp. n. is described from Polypogon monspeliensis from southeastern South Australia and Lachnagrostis filiformis from northern New South Wales, following an examination of nematode populations by allozyme electrophoresis and morphological analysis. Genetic differences were consistent with those expected from conspecific allopatric populations and were based on geography rather than host. Morphological differences between nematodes from P. monspeliensis and L. filiformis were inconsistent and varied between different gall types on the same host plant. The new species is characterised by adults with irregular and variable tail termini, which appear lobed; females may have a process of vestigial ovary extending from the post uterine sac towards the tail; males are dorsally curved with a single reflexed testis; and the haploid chromosome complement is n=18.

AbstractAn entomological radar was used to observe insect flight activity at a coastal locality in north-western Tasmania during the spring of 1973. Insects were regularly observed to take off at dusk, and local movements from nearby islands were detected on several occasions. Large-scale southward movements of insects across Bass Strait were also observed and were found to be associated with the warm anticyclonic airflows which occur ahead of a cold front. Light-trap catches indicated that the insects were noctuid moths, with Persectania ewingii (Westw.), Heliothis punctiger Wllgr. and Agrotis munda Wlk. dominant. The movements appear to have originated mainly in Victoria and south-eastern South Australia, but it is tentatively suggested that the ultimate source of the moths was in the region stretching westwards from north-western Victoria and south-western New South Wales towards the shores of the Spencer Gulf, South Australia.

The present paper completes a revision of the endemic Australian genus Cassinia R.Br. Cassinia subgenus Achromolaena comprises two sections, namely, section Achromolaena of seven species (C. laevis, C. arcuata, C. uncata, C. tenuifolia, C. collina, C. subtropica, and C. quinquefaria), and Cassinia section Siftonia, which contains two species (C. sifton and C. theodorii). Cassinia laevis is divided into western (C. laevis subsp. laevis) and eastern (C. laevis subsp. rosmarinifolia (A.Cunn.) Orchard, comb. et stat. nov.) taxa. Examination of the type of C. arcuata showed that this name is synonymous with C. paniculata, and applies to a relatively rare taxon with whitish capitula arranged in short erect compact panicles, and found in Western Australia, the midlands of South Australia, western Victoria and (formerly) south-western New South Wales. Furthermore, it belongs to section Achromolaena. The taxon with red to brown capitula, widespread throughout south-eastern Australia, which until now has been (incorrectly) known as C. arcuata (Sifton bush) is distinct, but lacks a published name. The name Cassinia sifton Orchard, sp. nov. is here proposed for this taxon. An unfortunate outcome of this discovery is that the sectional name Cassinia section Arcuatae, with C. arcuata as type, becomes synonymous with section Achromolaena. The new name Cassinia section Siftonia is proposed to accommodate Sifton bush (C. sifton) and its narrowly endemic sister species C. theodorii. A summary of the whole genus is provided, with keys to all taxa. Three former subspecies of C. macrocephala are raised to species rank (C. petrapendula (Orchard) Orchard, C. storyi (Orchard) Orchard, C. tenuis (Orchard) Orchard), and it is suggested that C. furtiva Orchard may be conspecific with C. straminea (Benth.) Orchard.
