Eastern underground orchid Rhizanthella slateri
Confined to small patches in eastern Australia, bizarrely, this cryptic, endangered species completely lacks chlorophyll, relying on its fungal partner for nourishment. The seed of this genus is unusual among Australian orchids, as it is carried in a berry-like fruit, in contrast to the dust-like seed of others. The flowers are thought to be pollinated by fungal gnats and the seed is eaten and distributed by bandicoots.
