If Serissa is a genus of a flowering plant, what is Westringia a genus of?
Serissa Serissa is a genus of flowering plants in the family Rubiaceae, containing only one species, Serissa japonica. It is native to open sub-tropical woodlands and wet meadows in southeast Asia, from India, and China to Japan. It is commonly called the snowrose, tree of a thousand stars, or Japanese boxthorn; and was formerly called Serissa foetida. 'Foetida' referres to the unpleasant, vomit-like, odour that the trees give off if their leaves are pruned or bruised.
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.
