| dc.description.abstract | The tribe Pomaderreae (10 genera, c. 240 species) is almost endemic to Australia and defined within Rhamnaceae by the presence of ‘stellate hairs’. This paper is the first to report observations on the leaf-indumentum of 33 species of the tribe with Scanning Electron Microscopy. Apart from simple hairs and papillae, three types of stellate trichomes were observed: fasciculate hairs, appressed stellate hairs and multiradiate hairs (sessile or stalked). The existence of stellate trichomes on the examined species of Pomaderreae was confirmed. Trichomes and indumenta are often variable within genera, as the type of indumentum may be more related to its function. Some groups of species in the genera Cryptandra Sm., Pomaderris Labill. and Stenanthemum Reissek have indumentum characters that seem to be more consistent and might be of value to elucidate relationships between taxa. | |
