Interspecific hybridization of Banksia hookeriana and Banksia prionotes was investigated via pollen tube growth, seed set, morphological measurements, and analysis of RAPD polymorphisms. Pollen tube growth to the ovary was observed following selfing and crossing pollination of each species and following interspecific hybridization to B. hookeriana as the female parent, but not in the reciprocal cross. All crosses resulted in seed set, except for self-pollination of B. prionotes and… Expand
Interspecific and Intergeneric Pistil-Pollen Compatibility of Banksia coccinea (Proteaceae)
TLDR
Results indicate a close relationship between Banksia and Dryandra, which are sister genera in the tribe Banksiae, family Proteaceae, and pollen-tube compatability in the lower style indicated that B. coccinea has a closer affinity to the section Oncostylis, than the section Banksia where it is currently placed.

Population-specific gender-biased hybridization between Dryopteris intermedia and D. carthusiana: evidence from chloroplast DNA.
TLDR
Analysis of Dryopteris Xtriploidea hybrids found differences in the chloroplast genome distinguishing the two parental species were discovered in the sequence of the trnL region following amplification by polymerase chain reaction (PCR), allowing rapid identification of the donor of the chlorOPlast genome, and therefore the maternal parent of each hybrid. Expand
Anthropogenic disturbance promotes hybridization between Banksia species by altering their biology
TLDR
It is concluded that anthropogenic disturbance promotes hybridization through increasing opportunities for gene flow by reducing interpopulation separation, increasing gamete production and, especially, promoting coflowering. Expand
Molecular analysis of interspecific and intergeneric relationships of Banksia using RAPDs and non-coding chloroplast DNA sequences
TLDR
The results indicate that interspecific and intergeneric hybridisation with genus Dryandra and subgenus Banksia may be possible routes for improvement of the commercial species B. coccinea. Expand
Detecting hybridization in mixed populations ofRhinanthus minor andRhinanthus angustifolius
TLDR
The development and use of species-specific RAPD and ISSR markers allowed the detection of hybrid individuals not always distinguishable with morphological characters, and showed traces of past hybridization and introgression. Expand
Contrasting impacts of pollen and seed dispersal on spatial genetic structure in the bird-pollinated Banksia hookeriana
TLDR
Paternity is assigned to quantify effective pollen dispersal over 9 years of mating, this to seed dispersal and their effects on fine-scale spatial genetic structure are examined, within the bird-pollinated shrub Banksia hookeriana (Proteaceae). Expand
Insect flower visitors, foraging behaviour and their effectiveness as pollinators of Persoonia virgata R. Br. (Proteaceae)
TLDR
No significant difference in fruit set was found between control flowers and cross-pollinated flowers, indicating that flower visitors of P. virgata were efficient vectors of cross-pollen from plant to plant. Expand
Temporal patterns of genetic variation across a 9‐year‐old aerial seed bank of the shrub Banksia hookeriana (Proteaceae)
TLDR
Variable fire frequencies have only limited potential to influence the amount of genetic variation stored within the seed bank of B. hookeriana, and results suggest that viability of seeds decreased with age, such that the viability of 9‐year-old seeds was half that of 2‐year‐old seeds. Expand
Long‐distance seed dispersal in a metapopulation of Banksia hookeriana inferred from a population allocation analysis of amplified fragment length polymorphism data
TLDR
The extent of long‐distance interpopulation seed dispersal observed provides a basis for explaining the survival of populations of the fire‐killed B. hookeriana in a landscape experiencing frequent fire, where local extinctions and recolonizations may be a regular occurrence. Expand
Genetic connectivity and inter-population seed dispersal of Banksia hookeriana at the landscape scale.
TLDR
The results show that genetic structure in an apparently strongly spatially structured landscape is not solely dependent on landscape structure, and that many physically defined geographical populations were genetic mosaics. Expand

Honeyeaters and the Pollination Biology of Banksia prionotes (Proteaceae)
TLDR
Despite the small size and isolation of the population studied, the resultant level of follicle formation per infructescence, and percentage seed set, are greater than for most other Banksia species for which data are available. Expand
Self-incompatibility, protandry, pollen production and pollen longevity in Banksia menziesii
TLDR
Results indicate that B. menziesii requires pollen vectors to produce seed and suggest that pollinators may have influenced the evolution of the reproductive traits that were examined. Expand

TLDR
Three western North American plant groups containing florally isolated species that hybridize are examined in relation to these predictions, and the evidence in the three groups is generally in agreement with the hypothesis. Expand
Seed Bank Dynamics of Three Co-Occurring Banksias in South Coastal Western Australia: the Role of Plant Age, Cockatoos, Senescence and Interfire Establishment.
TLDR
Seed bank dynamics of three co-occurring, non-sprouting Banksia species in patch-burnt scrub-heath (aged 10 and 21 years) were studied in the southern sandplains of Western Australia, finding that seed storage per year increased exponentially with plant age in B. coccinea and a quadratic function, peaking at 16 years, best described seed storage.

Pollen Presenter and Pollen Morphology of Banksia L.f. (Proteaceae)
TLDR
There was a higher level of between species and between group consistency in pollen grain than in pollen presenter structure, which has implications for both the interspecific fertility relationships and taxonomy of the genus Banksia. Expand
Pistil Structure of Banksia menziesii R.Br. (Proteaceae) in Relation to Fertility
TLDR
The morphology and histochemistry of the pistil of Banksia menziesii were studied to determine whether the observed low fertility of the species has a structural basis, and there was no variation in pistil structure which would explain the observedLow fertility. Expand
Comparative size, fecundity and ecophysiology of roadside plants of Banksia hookeriana
TLDR
The crowns of roadside plants of Banksia hookeriana were on average 2.34 times larger than their non-edge counterparts for a range of ages at five sites, apparently due to greater access to water, lower pre-dawn xylem tensions and diurnal leaf temperatures and mineral nutrients. Expand

TLDR
RAPD markers were used to assess the relationship among species, cultivars and hybrids of lilacs and it was felt that RAPD markers will be very useful for assessing the origin of cultivar and hybrid of many plant species. Expand

Inflorescence colour showed wide variation in both species, with red and pink being the dominant colours in B. coccinea and B. menziesii respectively. Expand
