Cladistic Biogeography

The contributions of Nancy Burbidge and Leon Croizat to an understanding of Australian phytogeography are summarised and compared. The focus of systematics on relationship and nodes of cladograms is outlined as the basis of modern cladistic biogeography. It is argued that development of explicit analytical methods for the discovery of general area cladograms has been hindered by lack of recognition of geographic paralogy—evidenced by duplication or overlap in geographic distribution of taxa related at a node in a cladogram. A new method, subtree analysis, which recognises and eliminates paralagous nodes, and often inconsistencies, is illustrated with examples from the Australian flora. General patterns are congruent with conclusions of Burbidge and Croizat. Paper Presented as the 1996 Nancy Burbridge Memorial Lecture.

AbstractThe broad brush strokes of Dorothy Cottrell's paintings in the National Library of Australia mark her as a modernist artist, although not one who painted the burgeoning Sydney Harbour Bridge or bright still-life paintings of Australian flora. Rather, she captured the dun surrounds of Ularunda Station, the remote Queensland property to which she moved in 1920 after attending art school in Sydney. At Ularunda, Cottrell eloped with the bookkeeper to Dunk Island, where they stayed with nature writer E.J. Banfield, then relocated to Sydney. In 1924 they returned to Ularunda and Cottrell swapped her paintbrush for a pen, writing The Singing Gold. After advice from Mary Gilmore, whom her mother accosted in a pub, Cottrell send it to the Ladies Home Journal in America. It was snapped up immediately, optioned for a film and found a publisher in England, who described it as ‘a great Australian book, and a world book’. Gilmore added, ‘As an advertisement for Australia, it will go far — the Ladies Home Journal is read all over the world’. Cottrell herself also went far, emigrating to America, where she wrote The Silent Reefs, set in the Caribbean. Cottrell's creative, intellectual and physical peregrinations — all undertaken in a wheelchair after she contracted polio at age five — show how the local references the international, and vice versa. Through an analysis of the life and writing of this now little-known Queensland author, this essay reflects the regional and transnational elements of modernism as outlined in Neal Alexander and James Moran's Regional Modernisms, illuminating how a crack-shot with a rifle once took Queensland to the world.

Morphological Differences

The current paper presents molecular data from three chloroplast markers (atpB–rbcL spacer, trnG G2 intron, trnL–trnF intron and spacer); morphological data, and geographic data to support the recognition of nine species belonging to Radula subg. Odontoradula in Australasia. R. ocellata, the subgeneric type from the Wet Tropics bioregion, is maintained as distinct from its sister species, R. pulchella, from south-eastern Australian rainforests; both species are Australian endemics. Reinstatement of R. allisonii from synonymy, under R. retroflexa, is supported by molecular data and morphological characters, including the absence of triradiate trigones on leaf-lobe cell walls, the apex of lobules on primary shoots not being turned outwards, the oblong-elliptic female bracts, and the perianths having a pronounced wing. Reinstatement of R. weymouthiana, from synonymy under R. retroflexa, is also supported by molecular data and morphological characters, including the presence of a single low dome-shaped papilla over each leaf-lobe cell, and the large imbricate lobules on primary shoots. R. weymouthiana occurs in Tasmania and New Zealand, whereas R. allisonii is a New Zealand endemic. Australian R. retroflexa exhibits differentiation into epiphytic and rheophytic morphs, interpreted as ecotypes. Australian individuals, comprising both epiphytic and rheophytic morphs, are monophyletic and nested within a clade containing individuals from other regions. R. novae-hollandiae is newly reported for the New Zealand Botanical Region, from Raoul Island in the Kermadecs. R. novae-hollandiae exhibits decoupling of morphological and molecular divergence, with Australian individuals forming two clades reflecting geography (a Wet Tropics bioregion clade and a south-eastern Rainforest clade). These clades exhibit equivalent levels of molecular divergence, as observed in R. pulchella and R. ocellata, but no morphological differences. Similar levels of molecular divergence were observed in trans-Tasman populations of R. tasmanica. The New Zealand endemic, R. plicata, is excluded from the Australian flora, and R. cuspidata replaces R. dentifolia for the New Zealand endemic species formerly known by both names.

In this paper, nomenclatural issues concerning nine Amaranthus taxa in the Australian flora are clarified. Lectotypes are designated for names of three currently accepted species (A. interruptus R.Br., A. rhombeus R.Br. and A. undulatus R.Br.) and two names now being considered to be taxonomic synonyms (A. lineatus R.Br. and A. macrocarpus var. pallidus Benth.). The earlier ‘holotype’ citations for the taxonomic synonym A. incurvatus Timeroy ex Gren. & Godr. and the currently accepted species A. quitensis Kunth are here considered effective lectotypifications. The holotype material for the nomenclatural synonym A. mitchellii var. grandiflorus J.M.Black is clarified. A neotype is designated for A. pallidiflorus var. viridiflorus Thell. (now considered to be a taxonomic synonym).

Sectional Classification

A molecular phylogeny, morphological descriptions, species lists and a key to the sections of Croton L. (Euphorbiaceae) recognised for Australia are presented. The molecular phylogenetic results supported the recognition of six sections, to account for the 29 native Australian species. The monophyly of each of these sections was highly supported in the Bayesian and maximum-likelihood analyses of nuclear ITS and plastid trnL–F DNA sequences, whereas their relationships to each other and to other groups were less well resolved. Croton may represent one, two or three separate arrivals to Australia, with support for hypotheses of subsequent dispersals from Australia to Pacific islands and to Asia. Croton sections Argyrati, Arnhemici, Caudati, Dockrilliorum and Insulares are newly described. Croton section Gymnocroton Baill., previously placed in synonymy, is again recognised. Croton armstrongii S.Moore is excluded from the Australian flora.

Ten taxa of marine diatoms from SE. or NE. Australia are described or redescribed, and their characters are supplemented by fine-structural and developmental data. One genus (Pseudoguinardia von Stosch), one species (Pseudoguinardia recta von Stosch), and two varieties (Odontella retiformis var. trigona von Stosch and Haslea gigantea var. tennis von Stosch) are newly described. Six other taxa [Coscinodiscus alboranii Pavillard, C. concinniformis Simonsen, Dactyliosolen blavyanus (Peragallo) Hasle, Rhizosolenia phuketensis Sundstrom, Haslea gigantea (Hustedt) Simonsen, and H. wawrikae (Hustedt) Simonsen] are new to the Australian flora. Gross and fine-structural characters are added to the descriptions of the world-wide and common R. stolterfothii (Stolterfoth) Peragallo and of the non-Australian Odontella retiformis var. retiformis von Stosch in order to bring them on a level of detail sufficient for their comparison with R. phuketensis or the new variety, respectively. The new species, although overlooked up to now, as well as C. alboranii and probably R. phuketensis, seem to be distributed world-wide in warmer neritic waters.
