The Ghost Orchid
The Ghost Orchid Epipogium aphyllum is an extremely rare species found in a very small number of sites within the UK. The plant feeds by parasitising fungi, rather than through photosynthesis and as a result is largely colourless, hence its name. It was deemed extinct in 2005 but a new specimen was found in 2009 and was later collected after being eaten through by a slug. The National Museum Wales Herbarium has seven specimens of this orchid, five courtesy of marauding slugs.
The specimen pictured was also cut down by a slug but this is even more rare, because of the way it has been preserved. This specimen was collected in 1982 and placed into a solution of formalin. The specimen arrived on my desk last week and I have since provided new labels, a new jar and it is now in a new preserving fluid of 10% DMDM Hydantoin and 0.5% glycerol increase its longevity and improve visual clarity. By preserving this specimen in fluid its 3 dimensional morphology is clearly demonstrated and the fluid gives it an even more ghostly appearance.
