Abutilon oxycarpum is a soft-woody shrub growing up to 2 m tall, found naturally on rocky hill slopes as well as creek banks in dry sclerophyll woodlands and forests and sometimes in rainforest, in all states of Australia with the exception of Tasmania. In NSW, it grows on the coastal, tablelands and western slopes, with most of its distribution north of Sydney (but also extending down the south.
The leaves are heart-shaped, to 7 cm long and 2.5 cm wide, with fairly obvious veins and with a velvety texture. The leaf margins are toothed and slightly hairy and the stems are hairy. Some of the hairs are stellate (star-shaped – a typical feature of this plant (Hibiscus) family).
Solitary yellow flowers are produced, to about 15 mm in diameter, occurring at different times in each state or territory.
Fruits are star-shaped about 8 mm in diameter, consisting of mericarps which split apart, each having a long sharp awn, clothed in stellate hairs.
Grows in full sun to partial shade on a wide range of soils.
Flowers attract bees and butterflies.
From seed or stem cuttings.
Two varieties are known and are sometimes separated on the leaf shape and indumentum. However, these are not currently recognised in NSW.
Can be often mistaken for a weed due to it leaf shape and texture and overall appearance.
Most Malvaceae members regenerate from seed after fire and after heavy rain.
Abutilon – a word derived from Arabic meaning “mulberry” or possibly “maple”.
oxycarpum – from the Gk. oksis (oξσύς) meaning acute (sharp) and carpum – Latin for fruit – referring to the sharp awns on the mericarps.
Not known to be threatened in the wild.
