Gallery: The most poisonous plants in Australia
They may seem innocuous, but some plants can be deadly. Here are some of the most poisonous in Australia.
Black bean (Castanospermum australe)
Native to Queensland and New South Wales, the black bean, or 'Moreton Bay chestnut', thrives in moist soil along river banks and mountainsides in coastal rainforests and is considered a valuable source of timber.
Between March and May, it produces large pods filled with toxic seeds that weigh roughly 30g each. Ingesting the seeds can cause vomiting and diarrhoea and can be serious if medical attention is not sought.
