If Serissa is a genus of a flowering plant, what is Westringia a genus of?
Westringia Westringia is a genus of Australian shrubs. As with other members of the mint family their upper petal (or lip) is divided into two lobes. There are four stamens - the upper two are fertile while the lower two are reduced to staminodes. The leaves are in whorls of 3 or 4.
Senegalia Senegalia (from Senegal and "Acacia senegal" ) is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Mimosoideae. Until 2005, its species were considered members of "Acacia." The genus is still considered polyphyletic and will require further division. "Senegalia" can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules.
