Rhytidosporum is a genus of flowering plants within the family Pittosporaceae.[1][2] The type species is Rhytidosporum procumbens (Hook.) F.Muell.[3]
Description

Rhytidosporum species are generally small herbs, or low shrubs, with alternate leaves which are often toothed at the apex.[2] The flowers are small, generally solitary, and occur both in the axils and terminally.[2] The five equal petals are white often tinged with red.[2] The anthers shed their pollen longitudinally.[2] The capsule is stalkless, with generally two locules.[2] The seeds are dry, wrinkled and wingless.[2]

There are five species, which are endemic to Australia:[1][4]
