Habenaria myriotricha was first named by
Kraenzl in 1893,caled Habenaria medusa.How-
ever,the taxonomy of Habenaria myriotricha ali-
ance was confused(Kurzweil,2009).Here we fol-
low current opinion about this species.Kew’s
World Checklist of Monocotyledons(http://www.
kew.org/wcsp/ monocots/),Schuiteman et al.
(2008)and Cavestro(2007)consider the two taxa
as conspecific.The specimens from Yunnan repre-
sented the first record of this species in China.
Habenaria myriotricha is related to Habenaria
medioflexaTurril(Lang,1999),but differs from
the latter by its reflexed lateral sepals and lip often
with some red rusty spots at the base.
