Abstract: Habenaria chlorina E. C. Parish & Rchb. f. (Orchidaceae)ꎬ a newly recorded
speciesꎬ is reported from China for the first time. The species is characterized by its floral
bract with marginal short hairs. It is similar to H. acuifera and H. linguellaꎬ but differs by its
spur having no ridge rising in front of the entrance.
Key words: Habenaria chlorinaꎻ Orchidaceaeꎻ Newly recordedꎻ China
    Habenaria Willd. ( Orchidaceaeꎬ Orchidi ̄
nae) is one of the largest genera of terrestrial or ̄
chids. It is well represented in both the New and
Old World tropics and subtropicsꎬ with a few
species extending into temperate areasꎬ particu ̄
larly in eastern Asia[1] . The principle centers of
diversity of Habenaria are in Brazilꎬ southern and
central Africaꎬ and east Asia[2-4]ꎬ and the genus
is currently estimated to comprise 876 species[5] .
Habenaria is represented by 58 species in
China[6-11] . Habenaria chlorinaꎬ described belowꎬ
is a newly recorded species from China.

ridge rising in front of the entrance. In additionꎬ
the floral bract with marginal short hairs is an
obvious unique characteristic compared with other
species in the genus Habenaria[12] . According to
the illustration from the type specimenꎬ the shape
of the pollinium is ellipse and the caudicle is linear
and curved upwardꎬ which might be incorrect
(Fig􀆰1: G). We anatomized the flowers and certified
that the shape of the pollinium was obovate ̄
oblong and the caudicle was nearly oblong and
slenderꎬ which was the same as the illustration
from the genus Habenaria in Thailand[3](Fig􀆰1: F).
Problematicallyꎬ no holotype was assigned
by the author when the first specimen of this spe ̄
cies was publishedꎬ but was taken from two
specimens collected from K (Parish C.S.P.ꎬ 124
and Parish C.S.P.ꎬ 245 as the type speci ̄
men) [13] . According to the rules of the Interna ̄
tional Code of Nomenclature for Algaeꎬ Fungi
and Plantsꎬ either of these two specimens could
be the syntype but no one had the work to assign
one specimen from syntype as the lectotype.
Accordinglyꎬ in this paperꎬ we assigned the
specimen of Parish C.S.P.ꎬ 245 (Kꎬ type) as the
lectotype.
