The Balanophoraceae (from the inflorescence which appears to be covered by barnacles) are a subtropical to tropicalfamily of obligate parasiticflowering plants, notable for their unusual development and obscure affinities. The family consist of 17 genera and around 50 species. The plants are normally found in moist inland forests growing on tree roots and have an aboveground inflorescence with the overall appearance of a fungus, composed of numerous minute flowers. The inflorescences develop inside the tuberous underground part of the plant, before rupturing it and surfacing. The plants are monoecious, or dioecious, and the fruits are indehiscent drupes or nuts. The underground portion, which attaches itself to the host, looks like a tuber, and is not a proper root system. The plants contain no chlorophyll. Balanophora means "bearing an acorn" (shape of the female inflorescence).
