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.
Lagunaria Lagunaria is a monotypic genus in the family Malvaceae. It is an Australian plant endemic to Lord Howe Island, Norfolk Island and parts of coastal Queensland. It has been introduced to many parts of the world. The genus was named for its resemblance to the earlier genus "Laguna" Cav., which was named in honour of Andrés Laguna, a Spanish botanist and a physician to Pope Julius III.
