- G. W. A. Nyakairu, C. Koeberl, H. Kurzweil
- Geology
- 20 August 2001
Kaolin from the Buwambo deposit, located about 27 km north of Kampala (Uganda), has been analyzed for its mineralogical and chemical composition. The kaolin is derived from granite of the basement,… Expand

- Plant Systematics and Evolution
- 1 September 1993
The seed morphology of 151 species of Southern AfricanOrchidoideae (Orchideae andDiseae; sensuDressler 1981) was studied by means of scanning electron microscopy. Two different seed types were found.… Expand
