[10] The name "Rhizanthes" is derived from the Ancient Greek words rhiza meaning "root"[11]:666 and anthos meaning "flower". Jack had found the first subterranean flowering plant. Last year, using radioactive tracers, scientists at The University of Western Australia showed that the orchid gets all its nutrients by parasitising fungi associated with the roots of broom bush, a woody shrub of the WA outback. So we set up infra-red cameras in Bulahdelah as part of the bypass project to find out what animals might disperse the seeds of the underground orchid. \:^'E;k.f--pk RRH T}(s However, we do not guarantee individual replies due to the high volume of messages.
