Diurideae is a tribe of orchid in the subfamily Orchidoideae. The tribe has a centre of diversity in Australia, with occasional dispersals to New Zealand, New Calendonia, Papua New Guinea, and Malesia. [1][2]
The tribe is estimated to have originated in the Eocene (c. 52Ma), with a crown age of c. 46 Ma. [1] The tribe is known for an unusually high number of species which engage in sexually deceptive pollination, particularly in the subtribes Caladeniinae and Drakaeinae.[2][3] Additionally, members of the Diurideae appear to have a high degree of fungal symbiont specificity, with orchid species partnering with an average of only one to two fungal species. [1][4]
Genera
Diurideae contains about 40 accepted genera.[5] Chase et al. (2015) accepted the following genera.[5] Some have since been combined.
