Description
Plants in the genus Asterolasia are erect or prostrate shrubs. They have simple leaves arranged alternately along the stems, and are simple with smooth edges. The flowers are bisexual and have five sepals, five petals and ten to twenty-five stamens. The sepals, petals and stamens are all free from each other, the stamens slightly shorter than the petals. There are five carpels fused at the base, sometimes to the tip usually with a small beak with the styles fused to each other with a shield-shaped stigma. The fruit is composed of up to five follicle and the dull, black seeds are released explosively.
Taxonomy
The genus Asterolasia was first formally described in 1854 by Ferdinand von Mueller in Transactions of the Philosophical Society of Victoria.
