Muelleria: An Australian Journal of Botany
new species of Boronia (Rutaceae) endemic in Victoria. Muelleria 8(1): 21-25 (1993).-Two new species of Boronia {B. citrata and B. galbraithiae) endemic in eastern Victoria, are described and illustrated. Their ecology, distribution and conservation status and relationships with other species are discussed.
M.F. Duretto. Taxonomic notes on Boronia species of northwestern Australia, including a revision of the Boronia lanuginosa group (Boronia section Valvatae: Rutaceae). Nuytsia 11(3): 301-346 (1997). The revision of Boronia (Rutaceae) in the Northern Territory, the Kimberley Region of Western Australia, and northwestern Queensland is completed, and a key to all species is provided. The B. lanuginosa Endl. species group is characterized as those species with pinnate leaves, a calyx as large as or larger than the corolla, multiangular stellate hairs, and a pronounced ridge on the micropylar side of the seed. This clade comprises the B. lanuginosa species complex, B. filicifolia A. Cunn. ex Benth., B. pauciflora W. Fitzg. and five newly described species: viz. B. decumbens Duretto, B. minutipinna Duretto, B. kalumburuensis Duretto, B. jucunda Duretto and B. tolerans Duretto. The B. lanuginosa species complex has four available names and was analysed numerically using phenetic methods. Two taxa were identified in the analysis. Boronia artemisiifolia var. wilsonii F. Muell. ex Benth. is raised to specific status while B. affinis R. Br. ex Benth. and B. artemisiifolia F. Muell. are synonymized under B. lanuginosa. Additionally, B. rupicola Duretto is described, and B. filicifolia, B. lanceolata F. Muell., B. lanuginosa and B. pauciflora are lectotypified. Boronia lanuginosa species complex Endlicher (1837) described B. lanuginosa from material that was collected by Ferdinand Bauer and labelled King George's Sound. King George Sound is in southwestern Australia, but Bauer had travelled with Matthew Flinders, on the "Investigator", around northern Australia (see Specht 1958a,b; Wilson 1975). Bentham (1863), who had not seen the type material of B. lanuginosa, applied this name to a southwestern Western Australian species that is found growing around King George Sound (Wilson 1975). Later, Mueller (1859) described B. artemisiifolia (as B. artemisifolia) from material he collected while on Gregory's Northern Australian Expedition. Bentham (1863) used this later name (written as B. artemisiaefolia) in his "Flora Australiensis". Subsequently, and up until 1975, specimens of Boronia from northern Australia that had a dense indumentum, pinnate leaves and a large calyx have been called B. artemisiifolia, with orthographic variation. After studying type material of B. lanuginosa, Wilson (1975) realized Bentham's error and synonymized B. artemisiifolia with B. lanuginosa. He concluded that the type locality of B. lanuginosa was somewhere on the coast of Arnhem Land where Flinders'ship "The Investigator" had travelled on its second voyage. Robert Brown, who was on "The Investigator" with Bauer and Flinders, collected plant specimens from the islands of the Gulf of Carpentaria that are identical to the type material of B. lanuginosa (Wilson pers. comm.), strengthening Wilson's argument. The southwestern Western Australian species that had previously been called B. lanuginosa is now known as B. stricta Bartl. (Wilson 1975). Bentham (1863) described B. affinis, B. filicifolia and B. artemisiifolia var. wilsonii (presently synonymized under B. lanuginosa) from northwestern Australia. The type material of B. affinis ("N. Australia. Islands of the Gulf of Carpentaria, and mainland opposite Groote Eylandt") was collected by Robert Brown while travelling with Matthew Flinders and Ferdinand Bauer on "The Investigator" in 1802-03. The main feature that has been used to distinguish B. affinis from B. lanuginosa is that B. affinis is glabrous or has a sparse indumentum while B. lanuginosa has a dense indumentum. There is much confusion surrounding the application of these two names. Judging from present herbarium records and collections, B. affinis and B. lanuginosa are sympatric in the Northern Territory. Boronia affinis is considered to be rare, possibly endangered, and confined to the Northern Territory (Briggs & Leigh 1988 [not listed in Briggs & Leigh 1996]; Hnatiuk 1990) while B. lanuginosa (as currently circumscribed) is common and widespread from King Sound (WA) to Wollogorang Station (NT) (Figure 1). Boronia lanuginosa has an ontogenetic sequence in leaf development from glabrous leaves, or leaves with a sparse simple and stellate indumentum, to leaves having a dense stellate indumentum, as has been observed in other members of section
A cladistic analysis of Boronia section Valvatae (Rutaceae)
Australian Systematic Botany, 1998
A phylogenetic analysis, using 55 morphological and anatomical characters, of all 58 species of Boronia section Valvatae was completed. On the basis of this analysis B. alata, B. algida and B. edwardsii are removed from section Valvatae and it is proposed that two new sections be erected to accommodate them. Boronia section Valvatae s. str., apart from valvate and persistent petals, is defined by the of presence stellate hairs, valvate sepals and axillary inflorescences. An infrageneric classification, based on the cladogram, of Boronia section Valvatae s. str. is proposed and includes four subsections, nine series and five subseries. Of the four subsections, Ternatatae is endemic to the south-west of Australia, Bowmaniae to Cape York, and Grandisepalae to the ‘Top End’ of the Northern Territory (including north-west Queensland) and the Kimberley Region. Subsection Valvatae is widespread but is predominantly found in the south-east of Australia
The discovery, naming and typification of Bougainvillea spectabilis (Nyctaginaceae)
Willdenowia
The bougainvillea (Bougainvillea spectabilis) was first collected by Philibert Commerson on the Bougainville expedition in Brazil, subsequently by members of the party accompanying Joseph Banks on Cook's first voyage around the globe and later by Frei Velloso. A copper engraving published by Lamarck formed the basis for Willdenow's publication of the name Bougainvillea spectabilis, which is here typified with an epitype in the Museum National d'Histoire NatureIle, Paris. A selective synonymy is given and early records on the introduction of this ornamental climber in Europe are critically analysed.

Boraginaceae s.str. is a subcosmopolitan family of 1600 to 1700 species in around 90 genera, and recent phylogenetic studies indicate that the infrafamilial classification as currently used is highly obsolete. The present study addresses the relationships of the major clades in Boraginaceae s.str. with an emphasis on monophyly of, and relationships between previously recognized clades and the position of various unplaced genera such as Afrotysonia, Anoplocaryum, Brachybotrys, Chionocharis, Craniospermum, Thyrocarpus, and Trigonocaryum using three plastid markers and a taxon sampling with four outgroup and 170 ingroup species from 73 genera. The phylogeny shows high statistical support for most nodes on the backbone and within individual clades. Echiochileae are confirmed as sister to the remainder of Boraginaceae s.str., which, in turn, fall into two well-supported clades, the Boragineae + Lithospermeae and the Cynoglosseae s.l. The latter is highly resolved and includes the Lasiocaryum-clade (Chionocharis, Lasiocaryum, Microcaryum) and the Trichodesmeae (Caccinia, Trichodesma) as sister to the remainder of the group. Rochelieae (formerly the Eritrichieae s.str., also including Eritrichium, Hackelia, and Lappula) form a poorly supported polytomy together with the Mertensia-clade (also including Anoplocaryum, Asperugo, and Memoremea) and the Omphalodesclade. The enigmatic genus Craniospermum (Craniospermeae) is sister to an expanded Myosotideae (also including Brachybotrys, Decalepidanthus, Trigonocaryum, and Trigonotis) and these two clades are in turn sister to the Core-Cynoglosseae, in which Afrotysonia glochidiata and Thyrocarpus sampsonii are included. Core-Cynoglosseae again fall into two pairs of well-supported subclades. The majority of generic placements are now resolved satisfactorily and the remaining phylogenetic questions can be clearly delimited. Based on the extensive phylogenetic data now available we propose a new infrafamilial classification into three subfamilies and 11 tribes, representing a consensus among the participating authors, according to which major clades are renamed.
Boronia keysii Taxon Profile and Habitat Map, June 2014
SEQ Catchments habitat mapping methodology produces the known and possible spatial extent and importance of Boronia keysii habitat within the Southeast Queensland bioregion. The approach relies on statistical analysis of preferred habitats and landscape criteria for the species. The resultant GIS Modelling is evaluated by expert review and further validated through ground-truthing and correlated with additional species records. This method aims to overcome bias's and gaps in species observations and provides a defensible, robust and precautionary approach to habitat mapping.
Australian Systematic Botany, 2012
Harrya is described as a new genus ofBoletaceae to accommodate Boletus chromapes, a pink-capped bolete with a finely scabrous stipe adorned with pink scabers, a chrome yellow base and a reddish-brown spore deposit. Phylogenetic analyses oflarge-subunit rDNA and translation elongation factor 1 a confirmed Harrya as a unique generic lineage with two species, one of which is newly described (H. a triceps). Some Chinese taxa were recently placed in a separate genus, Zangia, supported by both morphology and molecular data. Multiple accessions from Queensland, Australia, support the synonymy of at least three species in a separate Australian clade in the new genus, Australopilus. The truffle-like Royoungia is also supported as a separate lineage in this clade ofboletes. Even though it lacks stipe characters, it possesses the deep, bright yellow to orange pigments in the peridium. Additional collections from Zambia and Thailand represent independent lineages of uncertain phylogenetic placement in the Chromapes complex, but sampling is insufficient for formal description of new species. Specimens from Java referable to Tylopilus pernanus appear to be a sister group of the Harrya lineage.
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.
