Which genus has more species, Astilbe or Pittosporum ?
Pittosporum Pittosporum ( or ) is a genus of about 200 species of flowering plants in the family Pittosporaceae. The genus is probably Gondwanan in origin; its present range extends from Australasia, Oceania, eastern Asia and some parts of Africa. "Citriobatus" is usually included here, but might be a distinct (though closely related) genus. They are commonly known as pittosporums or, more ambiguously, "cheesewoods".
Pittosporum tobira Pittosporum tobira is a species of flowering plant in the Pittosporum family known by several common names, including Australian laurel, Japanese pittosporum, mock orange and Japanese cheesewood. It is native to Japan, China, and Korea, but it is used throughout the world as an ornamental plant in landscaping and as cut foliage.
