Sarcopetalum harveyanum (meaning: Fleshy petals) is common in or near rainforest and is also often found in moist eucalypt forest, chiefly in coastal areas along the eastern seaboard of Australia: from Victoria, through New South Wales, right up into Queensland.
You have to be very lucky to see the tiny flowers of Sarcopetalum harveyanum as they are held on short racemes, 3 to 7cm long, and only last a day or so. The flowers are very, very tiny, with petals about 3 mm long – and they pop straight out from the trunk of the vine, generally on the old wood. The old wood of this vine is usually high in the canopy of the rainforest hence the difficulty in spotting the tiny flowers.
They are odd in the way they can pop out of the ground or an old stalk where there are no leaves, or anything else to give you a clue as to the name of the vine.
