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.
Burkea africana The Wild syringa ("Burkea africana"; Bambara: "Siri" ) is a deciduous, medium-sized, spreading, flat-topped tree belonging to the family Caesalpiniaceae. The genus was named in honour of Joseph Burke, the botanist and collector.
