Two new species of rare parasitic orchids have been discovered in the Yanbaru forests of Japan, providing some fascinating insights into the diversity of this hugely varied family.
Kenji Suetsugu, Associate Professor at Kobe University of Graduate School of Science, recently published detailed descriptions of the species in the online journal, Phytotaxa.
Perhaps the most fascinating aspect of this discovery is that the two species described, Gastrodia nipponicoides and Gastrodia okinawensis, do not photosynthesise at all! They belong to a group of plants called myco-heterotrophs, which derive some or all of their nutrition from parasitising fungi.
Parasitic orchids are not unheard of, but they are incredibly illusive species because they only appear above ground very briefly when in flower.

parasitic or saprophitic ?
Hi Chris,
Biologically-speaking, a saprophytic organism is one that lives on decaying organic matter. These orchids are true parasites because they derive all of their nutrition from parasitising fungi (fungi which live on decaying organic matter!). They are more accurately called myco-heterotrophs in biological jargon for this reason.
