A cladistic and biogeographic analysis of Philotheca (Rutaceae) and allied genera

  title={A cladistic and biogeographic analysis of Philotheca (Rutaceae) and allied genera},
  author={M. Bayly},
This thesis considers the relationships, classification and historical biogeography of the related Australian endemic flowering plant genera Philotlzeca, Eriostemon and Crowea (family Rutaceae, tribe Boronieae). It focuses mostly on relationships within and between these genera, but also considers the relationships of these groups to other members of the tribe Boronieae, particularly the small genera Geleznowia and Drummondita. It includes a brief appraisal of the species-level taxonomy of… Expand

Development of leaves and shoot apex protection in Metrodorea and related species (Rutaceae)
Examination of leaf morphogenesis in Metrodorea and in closely related species finds that the number of leaflets in the studied species is dependent on the late or early determination of the leaf primordium, and that loss of leaflets may have been favoured by the restriction of space available for development within the cavity formed by the pair of united stipules.

The coumarins of Philotheca sensu lato: distribution and systematic significance
An analysis of the distribution of coumarins demonstrate that Geleznowia verrucosa is chemically indistinguishable from many species ofPhilotheca section Philotheca, whereas Philothecas section Erionema is more variable. Expand


Cladistic relationships and biogeographic patterns in the peppermint group of Eucalyptus (informal subseries Amygdalininae, subgenus Monocalyptus) and the description of a new species, E. willisii
A preliminary study of eastern Monocalyptus suggested that the peppermint eucalypts, informal subseries Amygdalininae, form a monophyletic group whose sister taxon is series Pilulares, but it was shown that they are not sister taxa. Expand

An infrageneric classification, based on the cladogram, of Boronia section Valvatae s. Expand
Relationships in the stringybarks, Eucalyptus L'Hérit, informal subgenus Monocalyptus series capitellatae and Olsenianae: phylogenetic hypotheses, biogeography and classification
The stringybarks are endemic to eastern mainland Australia plus Kangaroo Island, but not Tasmania, and the consensus area-cladogram suggests a sequence of seven historical events subdividing an ancestral area into eight smaller ones. Expand
Cladistic and Biogeographic Analysis of Western Australian Species of Eucalyptus L'Hérit., Informal Subgenus Monocalyptus Pryor & Johnson
A comparison with the geological and climatological history points to the Tertiary as the likely time of first speciation within Monocalyptus. Expand
A cladistic analysis of Boronia Sm. and Boronella baill. (Rutaceae)
Two competing hypotheses of cytoevolution in Boronia are evaluated by superimposing them onto the cladogram, and Smith-White's model requires fewer postulated polyploid and aneuploid changes in numbers of chromosome than James' model and is therefore preferred. Expand
Neobyrnesia (Rutaceae): a new genus endemic to Northern Australia
Allied to genera in the sub-tribe Boroniinae sensu Engler (1931), Neobyrnesia is distinguished from other genera of Rutaceae in the Australasian region by the following combination of characters. Expand
A cladistic analysis of the “blue ash” eucalypts found five equally parsimonious trees were found, and a strict consensus tree constructed, based on the consensus cladogram. Expand
Seedling characters and phylogenetic relationships in the informal series Ovatae of Eucalyptus, subgenus Symphyomyrtus
The results suggested that series Ovatae is a paraphyletic group, although one subgroup, approximately equivalent to subseries Ovatinae, is probably monophyletic, and a broader study of section Maidenaria is recommended before taxonomic revision. Expand
Morphometric Analysis of Variation in Geleznowia verrucosa Turcz. (Rutaceae)
Univariate analyses showed the small form exhibited significantly shorter leaves, bracts and sepals than the intermediate populations and the large form as well as more rounded leaves, which supports allozyme evidence that gene flow and introgression is/has occurred within this population. Expand
Genetic diversity in the monospecific Western Australian endemic, Geleznowia verrucosa Turcz. (Rutaceae)
Higher levels of divergence between the intermediate-form populations and increased heterozygosity at the Lap locus suggest that this form is of hybrid origin and has arisen through a series of hybrid events between the small and large forms. Expand
