Due to the time and energy required to extract resources from 15 morphologically complex flowers, these plant species potentially compete for pollinators with co- 16 flowering plants that have more easily accessible resources. A widespread floral mechanism 17 restricting access to pollen is the presence of tubular anthers that open through small pores or slits 18 (poricidal anthers). Some bees have evolved the capacity to remove pollen from poricidal anthers 19 using vibrations, giving rise to the phenomenon of buzz-pollination. These bee vibrations that are 20 produced for pollen extraction are presumably energetically costly, and to date, few studies have 21 investigated whether buzz-pollinated flowers may be at a disadvantage when competing for 22 pollinators’ attention with plant species that present unrestricted pollen resources. -

University Systematics of the Relhaniinae (Asteraceae- Gnaphalieae) in southern Africa: geography and evolution in an endemic Cape plant lineage. Nicola Georgina Bergh Town Thesis presented for theCape Degree of DOCTOR OF ofPHILOSOPHY in the Department of Botany UNIVERSITY OF CAPE TOWN University May 2009 Town Cape of University ii ABSTRACT The Greater Cape Floristic Region (GCFR) houses a flora unique for its diversity and high endemicity. A large amount of the diversity is housed in just a few lineages, presumed to have radiated in the region. For many of these lineages there is no robust phylogenetic hypothesis of relationships, and few Cape plants have been examined for the spatial distribution of their population genetic variation. Such studies are especially relevant for the Cape where high rates of species diversification and the ongoing maintenance of species proliferation is hypothesised. Subtribe Relhaniinae of the daisy tribe Gnaphalieae is one such little-studied lineage. The taxonomic circumscription of this subtribe, the biogeography of its early diversification and its relationships to other members of the Gnaphalieae are elucidated by means of a dated phylogenetic hypothesis. Molecular DNA sequence data from both chloroplast and nuclear genomes are used to reconstruct evolutionary history using parsimony and Bayesian tools for phylogeny estimation. -

SUMMARY Developmental constraints have been proposed different characteristics of microsporogenesis, only cell to interfere with natural selection in limiting the available wall formation appeared as constrained. We show that set of potential adaptations. Whereas this concept has constraints may also result from biases in the correlated long been debated on theoretical grounds, it has been occurrence of developmental steps (e.g., lack of successive investigated empirically only in a few studies. In this article, cytokinesis when wall formation is centripetal). We document we evaluate the importance of developmental constraints such biases and their potential outcomes, notably the during microsporogenesis (male meiosis in plants), with an establishment of intermediate stages, which allow emphasis on phylogenetic patterns in Asparagales. Different development to bypass such constraints. These insights are developmental constraints were tested by character discussed with regard to potential selection on pollen reshuffling or by simulated distributions. Among the morphology.

III IV Acknowledgements It has been an exciting journey working with the most beautiful plant genus of this world. There are many people I would like to thank for being a part of this journey. First and foremost, I want to thank my wonderful supervisors for all their help and support over the past two years. I could not have had a better team. My main supervisor, Charlotte - for your enthusiasm, knowledge, support and the most amazing field trips. In the 1970’s, before I was even born, Inger (and colleagues) worked with Scadoxus, which set the stage for this master thesis. I would like to thank Inger for being my additional supervisor and ultimately giving me this opportunity, and helping me understand more of Scadoxus morphology. Anne – for helping with the analyses, and especially for the incredibly helpful checking of spelling, grammatical errors and also helping me discourse my occasionally overwhelming results. Prof. Clemence Zimudzi and Dr. Tesfaye Awas – for fantastic field work experiences in Zimbabwe and Ethiopia, respectively. I would also like to thank the little kids in Ethiopia who helped us find Scadoxus specimens in places we never would have found without them. -
