Plants of this genus are commonly referred to as hyacinth orchids.〔 ==Description== The species are perennial terrestrial herbs or herbaceous climbers/epiphytes.〔 Many species, particularly in eastern Australia are leafless mycoheterotrophs. Others have medium-sized to very large leaves that are parallel-veined and with entire margins.〔 Flowers are arranged in a raceme with very few or up to 50 flowers. These may be fragrant or odourless, are white, pink, purple, yellow or green, often with spots or blotches.〔 The labellum is three-lobed.〔 Each of the flowers have two pollinia that are supported on two stipes.〔 Dehiscent capsules, produced after flowering, hold the seed which is released when they split longitudinally along six seams.〔 Between 30 and 500 seeds are produced per capsule.〔
