Balanophora is a genus of parasitic flowering plants in the family Balanophoraceae distributed from tropical Africa and Madagascar, through South and Southeast Asia, Japan, Queensland and the islands of the western Pacific.[2][3][4] There are over 20 accepted species.[1] Many species emit an odour which possibly attracts pollinators in the same way that pollinators are attracted to Rafflesia.[5] The tiny flowers produce some of the smallest seeds known, weighing as little as 7 micrograms each.[6]
Taxonomy
[edit | edit source]The genus was first described in 1775 by Johann Reinhold Forster and his son Georg Forster in Characteres Generum Plantarum.[7][8] The name is derived from the ancient Greek words balanos (βάλανος), meaning "acorn" and pherein (φέρειν), meaning "to carry".[9]

Ecology
[edit | edit source]Balanophora yuwanensis, "often considered the same species as B. yakushimensis", is thought to provide the endangered dark-furred Amami rabbit (Pentalagus furnessi) of the Ryukyu Archipelago with vegetative tissues as a reward for seed dispersal. Previously, it had been a mystery how seeds of B. yuwanensis were dispersed.[11][12]
Use
[edit | edit source]Balanophora species are used in folk medicine in many Asian cultures.[4] For example, in Taiwan and China, Balanophora is known as she-gu (snake-fungus) and in Thailand as hoh-ra-tao-su-nak. In both cases, the plant is used to treat a variety of ailments and has various ritual purposes. The tubers of Balanophora are rich in a wax-like substance which is used in Java as a fuel for torches.[5][13]
