Abstract:Habenaria vidua E.C.Parish &Rchb.f(Orchidaceae)is reported from China for the first time.The spe-
cies is characterized by its special habitat on limestone.It differs from the H.tonkinensis Seidenfaden by its green lat-
eral sepals and lip,and the side-lobes of lip sticking up.

摘 要:报道了中国云南兰科植物一新记录种,岩生玉凤花(Habenaria vidua E.C.Parish &Rchb.f)。该种主
要特点是生长在腐殖质比较丰富的石灰岩缝隙中,不同于属内其它物种。在植株和花部特征相似于丛叶玉凤花
H.tonkinensis,但侧萼片与唇瓣绿色、唇瓣侧裂片明显上举而区别于后者。

  Habenaria Wild.(Orchidaceae)is one of the lar-
gest genera of terrestrial orchids,wel represented in
both the new and old world tropics and subtropics,
with a few species extending into temperate areas,par-
ticularly in eastern Asia(Pridgeon et al.,2001).The
main centers of diversity of the genus are in Brazil,
southern and central Africa,and East Asia(Kurzweil
& Weber,1992).Current counts estimate the number
of Habenaria species at about 835(Govaerts et al.,
2010).In China,Habenaria is represented about 56
species(Chen &Cribb,2009;Wang &Wang,2010;Liu
et al.,2012),and the folowing described species is a
new record of Habenariafrom China.

long,(7-10)×(0.8-1.5)mm;lateral lobes pointing
upwards,linear to oblong,(12-15)×(0.8-1)mm;
spur cylindric,to 20-30mm,much longer than ovary.

Habenaria vidua was first named by Seidenfaden
in 1977,and he deemed that the long rachis arrived 10
-15cm was the key character difered from other spe-
cies(Seidefaden,1997).But,Kurzweil did not agree
with his view,and pointed out that the rachis was most
commonly shorter than this(Kurzweil,2009).This
species unlike any others of Habenaria with its unusu-
al habitat on limestone rocks,the characteristic lip
shape with the midlobe reflexed under the flower and
the lip side-lobes sticking up.
