Abstract
Studies on the morphology and cytology of two species, Aspilia africana and Spilanthes costata B. family Asteraceae, were conducted. The departmental botanical garden served as the source for the many specimens used.
The following was done cytological study, which includes mitosis and meiosis; tests showed that it was not possible to successfully confirm the chromosomal numbers of the two specimens. Epidermal morphology results showed that both specimens had anomocytic stomata and were amphistomatic. The average specimen height, as well as the average length and breadth of the leads, were determined and reported. Fertility in pollen was noticed
