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".
Polytrichum Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that cover a cosmopolitan distribution. (Less common vernacular names include bird wheat and pigeon wheat.)
