Western Australia's Incredible Underground Orchid
Rhizanthella gardneri is a cute, quirky and critically endangered orchid that lives all its life underground. It even blooms underground, making it virtually unique amongst plants.
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.
Now, with less than 50 individuals left in the wild, scientists have made a timely and remarkable discovery about its genome.

Re: Western australia's incredible underground orchid
Als deze plant helemaal onder de grond zit, maakt dat 'm nogal lastig om te vinden. Dus... hoe weten ze dat er minder dan 50 exemplaren van in het wild zijn? 't is niet dat je ze nu al van 10 Km afstand ziet liggen.

Re: Western australia's incredible underground orchid
Goeie vraag. Als hij bloeit steken de topjes van de bloembladen uit het zand om zo een opening in het zand te maken. Zoals op de foto.
