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.
Grevillea Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville. The species range from prostrate shrubs less than 50 cm tall to trees 35 m tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus "Hakea", the genus gives its name to the subfamily Grevilleoideae.
