Species diversity, ecology and evolution in a primitive Angiosperm genus:Hibbertia (Dilleniaceae)

Among the approximately 130 species ofHibbertia found in Australia, there are tall shrubs, low or trailing shrubs and vines bearing a diversity of leaves as to shape and venation pattern. Flowers are solitary, in leafy cymes or in false spikes, and display various gradual and abrupt transitions from vegetative to reproductive appendages. In the androecium, stamen number is highly variable both between and within species. Some sections have radial symmetry, others bilateral symmetry of the… Expand

Figures from this paper

Sympatric species of Hibbertia (Dilleniaceae) vary in dormancy break and germination requirements: implications for classifying morphophysiological dormancy in Mediterranean biomes.
Embryos grew during winter, but future studies need to resolve the role of cold versus warm stratification by using constant temperature regimes, and modifications to the current seed-dormancy classification system may need consideration. Expand
Developmental evidence for stamen number reductionin populations of Hibbertia fasciculata (Dilleniaceae)
General observations and comparative studies suggest that this population-based reduction series in stamen number reflects a locally successful trend towards smaller organs throughout the plant body together with a shift in pollination ecology. Expand
Notes on Hibbertia (Dilleniaceae) 5. H. melhanioides and H. tomentosa groups from tropical Australia.
Fifty-two species and many infraspecific taxa are described (52 as new), keyed out and placed into two groups and nine subgroups based on an assessment of the gross morphology anditure of Hibbertia §Tomentosae Benth. Expand
Remarks on karyological differentiation patterns in tropical woody plants
Karyomorphology suggests a new systematic arrangement for the Laurales, a new circumscription of theCymbopetalum tribe (Annonaceae), and a placement of theCochlospermaceae/Bixaceae in theViolales. Expand
Self-isolation and insect pollination in the primitive angiosperms: New evaluations of older hypotheses
A review of the literature, compiled over the past 40 years suggests new directions for theories discussing the evolution of reproductive isolation and entomophily in angiosperms. Data on breedingExpand
Notes on Hibbertia subg. Hemistemma (Dilleniaceae) 9. The eastern Australian H. vestita group, including H. pedunculata and H. serpyllifolia
The distributions of the species range from near Hobart in Tasmania to tropical Queensland, north of Rockhampton, and a key and full descriptions of all recognised taxa as well as selected illustrations are provided. Expand
The pollination biology ofHibbertia stricta (Dilleniaceae)
The pollination biology of H. stricta is compared with otherHibbertia spp. Expand
Bee-pollination inHibbertia fasciculata (Dilleniaceae)
The pollination biology of H. fasciculata is assessed in relation to the known radiation of bee-pollinated flowers in the genusHibbertia, and within the Dilleniaceae s. Expand
The Branching Stamens of Ricinus and the Homologies of the Angiosperm Stamen Fascicle
The nature of the highly unusual branched stamen of Ricinus communis is reevaluate, specifically whether it represents a telomic shoot‐derived (axial) structure or a classical foliar‐derived stamen that is compound or fascicled. Expand
Phylogenetics of Dilleniaceae Using Sequence Data from Four Plastid Loci (rbcL, infA, rps4, rpl16 Intron)

Ancestral‐state reconstructions of six morphological characters of both biological and taxonomic significance within Dilleniaceae suggest hypotheses of polarity or lability for each that differ substantially from those based on evolutionary trends. Expand


Myrmecochorous plants in Australia and their dispersal by ants
Field experinfents and observations indicate that c. 1500 species, representing 87 genera and 24 families, of Australian vascular plants are myrmecochorous, i.e. regularly dispersed by ants becauseExpand
The conclusion is drawn that arils are probably neither especially primitive nor homologous in all angiosperms, because such convergences already occur within one single order–an order which is generally considered, moreover, to be particularly primitive. Expand
Evolutionary Recall in Hypericum (Guttiferae)
Summary Evidence is adduced that the ‘hypogynous bodies’ found in two unrelated sections of Hypericum are, at the same time, ‘new’ organs in Hypericum and yet homologous with sterile stamen faciclesExpand
