The Botany Bay bearded greenhood is a terrestrial orchid growing only in Kamay Botany Bay National Park on the Kurnell Peninsula of New South Wales. This species is found on moist flat sites on sandy soils and in association with coastal heath dominated by Melaleuca nodosa (pricklyleaf paperbark) and Baeckea imbricata (a shrub). The Botany Bay bearded greenhood occurs in small localised populations, often within the heath where the canopy allows filtered light to reach the ground. Flowering typically occurs from August to September. This species is threatened by too frequent fires and long fire intervals as well as by habitat degradation related to unrestricted access.
