    2010-3-26 · Introduction. The rare underground orchid Rhizanthella gardneri is an obligately mycoheterotrophic orchid that lacks the ability to photosynthesize. Even during flowering, R. gardneri is entirely subterranean, a feature unique amongst known mycoheterotrophic orchids (Leake, 1994). R. gardneri also lacks roots and so has limited independent access to nutrient resources (Dixon & Pate, The Drift How do you get liquid nitrogen ,The Drift How do you get liquid nitrogen underground?
