Thrixspermum Loureiro (1790: 519) View in CoL . Type species: Thrixspermum centipeda Lour.

Dendrocolla Blume (1825: 286) View in CoL . Type species: Dendrocolla hystrix Blume.

Orsidice Reichenbach (1854: 93) View in CoL . Type species: Not designated.

Cylindrochilus Thwaites (1861: 307) . Type species: Cylindrochilus pulchellus Thwaites.

Ridleya View in CoL (Hook.f.) Pfitzer (1900: 16). Type species: Ridleya notabilis (Hook.f.) Pfitzer.

Cordiglottis Smith (1922: 95) View in CoL Type species: Cordiglottis westenenkii J.J.Sm. View in CoL

Cheirorchis Carr (1932: 40) View in CoL Type species: Cheirorchis breviscapa Carr.

Thylacis Gagnepain (1932: 599) View in CoL . Type species: Not designated.

Cordiglottis View in CoL was separated from Thrixspermum View in CoL based on its ‘non-saccate lip, long bent column, the nearly equal pollinia and the large stigma’ ( Smith 1922) and terete or laterally flattened leaves. However, the discovery of new Cordiglottis species made differences in floral characters appear less reliable; in addition, several Thrixspermum species with terete leaves are now known. Hence, a distinction based on morphological characters is difficult to maintain. Moreover, our molecular systematic studies found Cordiglottis View in CoL deeply nested in Thrixspermum View in CoL . With our current knowledge of the genus, Cordiglottis View in CoL cannot be kept separate unless Thrixspermum View in CoL is split into several smaller genera. We prefer, however, a more broadly circumscribed Thrixspermum View in CoL ( Fig. 1F View FIGURE 1 ). All species have ephemeral flowers, often lasting only a few hours.
