Discussion on the Taxonomic Status of Epipogium sessanum
The taxonomic status of Epipogium sessanum was discussed.By field observations and a critical survey of the literature and specimens in herbaria,it was found that E.sessanum and E.roseum had obvious differences in the flower.It is suggested E.sessanum to be reinstated as a distinct species,and a new Chinese name"zang nan hu she lan"is proposed.
