Article
Waterfall Bluff, in Eastern Mpondoland (Eastern Cape Province, South Africa), is a recently excavated archaeological site with deposits spanning Marine Isotope Stage (MIS) 3 to the Middle Holocene. Here, we present preliminary results of a multi-proxy palaeoenvironmental study combining macro-botanical remains, charcoal, phytoliths, pollen and plan...
Article
This paper presents the first insight into the interpretation of the wood charcoal from the Holocene layers of Wonderwerk Cave. Situated in the Northern Cape Province in the arid interior of South Africa, the site provides a unique and valuable chronological record of past environmental fluctuations and responding human behavioural adaptations span...

Ndondondwane in KwaZulu-Natal, South Africa, is an Early Iron Age site of a single, short-term occupation within the time period A.D. 750 to A.D. 950. This makes it a unique and ideal site to study cultural and social settlement organisation in this region. The site has been extensively excavated for archaeological research and a vast assemblage of...
Article
Anthers containing pollen grains of Barleria obtusa at various stages of development were examined to investigate pollen wall ontogeny. Whole anthers containing pollen grains were viewed with a light microscope, firstly to identify stages of pollen grain development and secondly to assess the state of the tapetum. Developing pollen grains were sect...
Article
The external pollen morphology of Justicia is diverse and offers a wealth of characters currently used for classifying species. The pollen morphology of 12 species of Justicia and six species from five closely related genera was investigated using a focused ion beam-scanning electron microscope (FIB-SEM). This method allows for three dimensional ex...
Article
External pollen grain morphology has been widely used in the taxonomy and systematics of flowering plants, especially the Acanthaceae which are noted for pollen diversity. However internal pollen wall features have received far less attention due to the difficulty of examining the wall structure. Advancing technology in the field of microscopy has...

Pollen grain morphology has been widely used in the classification of the Acanthaceae, where external pollen wall features have proved useful in determining relationships between taxa. Although detailed information has been accumulated using light microscopy, transmission electron microscopy and scanning electron microscopy (SEM) techniques, intern...
