Scanning Microscopy


Scanning electron microscopy was used to conduct a micromorphological study of testae of the seeds of 18 species of Rafnia Thunb. (Fam. Fabaceae, Sub-family Papilionoideae). The testa patterns revealed diagnostic taxonomic features which proved useful in the construction of a key for the identification of the various Rafnia species. Comparisons between air-dried freshly collected, and long-term stored herbarium specimens revealed that testa patterns remained consistent and valid for taxonomic purposes.
