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".
Sooty mold Sooty mold is a collective term for different Ascomycete fungi, which includes many genera, commonly "Cladosporium" and "Alternaria". It grows on plants and their fruit, but also environmental objects, like fences, garden furniture, stones, even cars. The mold benefits from either a sugary exudate produced by the plant or fruit, or if the plant is infested by honeydew-secreting insects or sap suckers.
