The uew geuus is luore or less related to Gastrodia, Aphijllorclds, Epi- 

 pogon aud Gahra, in its leafless liabit. It is, however, closely alUed to 

 Clieirostijlis in the garaophyUous perianth, deeply sinuate rosteUum, sectUe 

 pollinia, one or two armed coluraual appendages and stigraatic tissue at the 

 base on each side of the rosteUmn. But it cUifers frora it by the aphyUous 

 liabit, and by the nearly included long eutire labeUura with uo cUstiuctiou 

 of a blade and claw and with uo sweUing at the base.
