Balanophora tobiracola Makino

Family: Balanophoraceae
English: Balanophor (sp)
Japanese: キイレツチトリモチ (喜入土鳥餅) [Kiretsu Tsuchitorimochi]

Quite different from the other two balaophors in Yakushima, this native parasitic plant of south Japan bears both male and female that are quite obvious upon inspection.
