The list of common names for this species is hopelessly numerous. They include: Hairy Pittosporum, Yellow Pittosporum, Rough-fruit Pittosporum, Revolute Pittosporum, Lemon-fruit Pittosporum and Brisbane Laurel. I’ll just stick to Pittosporum revolutum!
Pittosporums are quite easy to tell to genus due to their ‘pseudo’-whorled leaves. This one I have here has the look of P. revolutum because of what I imagine is a leathery look to the leaves, and fruits are the best confirmatory feature – this species has rough fruits, a feature that distinguishes it from other similar species here. Otherwise, it may be easy to mistake other species such as P. ferrugineum and P. venulosum for this one. The yellow flowers are very ornamental.
