| − | The subsurface architecture of these terrestrial wild orchids consists of a [[rhizome]] structure, from which emanate [[tuber]]s. The rhizome extracts nutrients from fungal intermediates and may also store some of these nutrients. A basal rosette of leaves develops from the tuber at the surface of the soil, each of the two or three leaves being [[lanceolate]] in shape.<ref name="Morgan">Morgan & Ackerman, Lindleyana 5:205–211 (1990)</ref> Each leaf ranges from 10 to 15 centimeters in length and 20 to35 millimeters in width. Leaves of younger plants are often more diminutive in size.
