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.
Banksia rufa subsp. flavescens Banksia rufa" subsp. "flavescens is a subspecies of "Banksia rufa". It was known as Dryandra ferruginea" subsp. "flavescens until 2007, when Austin Mast and Kevin Thiele sunk all "Dryandra" into "Banksia". Since the name "Banksia ferruginea" had already been used, Mast and Thiele had to choose a new specific epithet for "D. ferruginea" and hence for this subspecies of it. As with other members of "Banksia" ser. "Dryandra", it is endemic to the South West Botanical Province of Western Australia.
