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.
Erica Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
