Common Name Slater's Rhizanthella [Australian Orchid Enthusiast 20th cent.] - Eastern Underground Orchid

Flower Size 1.2" [3 cm]

Found in New South Wales Australia at elevations of 10 to 1000 meters in montane forested habitats on lower western slopes as a miniature sized, warm to cool growing terrestrial with a fleshy, white rhizome with overlapping fleshy bracts that blooms in the spring on an erect, 4 to 6" [10 to 15 cm] long stem carrying numerous overlapping bracts and carrying a flowerhead

"Text by David Banks - The Eastern Underground Orchid (Rhizanthella slateri) was rediscovered at the type site at Alum Mt, Bulahdelah, New South Wales in May 2002. I was shown the plants and here is one of the photos I took of this rediscovery. The plant depicted is still in tight bud, but I will get flower shots in September. This plant is a rare Mycoheterotrophic orchid that lives beneath the soil and only as flowering is aproaching does it just broach the surface beneath the leaf litter, giving rise to a cluster of small tubular flowers. Since this find, five more colonies have been discovered at the Bulahdelah site."
