A weedy plant known for its tiny sharp-needled seeds. It appears with small feathery leaves reminiscent of parsley, with an exposed upward-pointing rosette of seeds in a pod nestled at the branch junctions. Eventually small bright flowers appear if the plant is allowed to develop. Those familiar with the plant may also know it as "bindi patches", which can't be walked on barefoot. Dogs and cats are no less affected and tend to avoid areas where they have encountered it.

Originally native to South America, the plant is now well established in many places around the world, including Australia, New Zealand, Hawaii, California, and several other states in the United States. It is mainly found in parks and ovals, though it has also become an invasive species in lawns in the southeast USA.
