The genus Odontochilus Blume belongs to subfamily Orchidoideae，Orchidaceae［1］． There are about 40 spe-
cies recorded worldwide． They range across the Himalayas and northern India，extend to southeast Asia in north-
ern Japan，east to the southwest of the Pacific Islands;11 species in China［1］． The Odontochilus elwesii C． B．
Clarke ex J． D． Hook was the only species recorded in Odontochilus genus in Fujian Province［2］． In September
22，2009，Odontochilus poilanei (Gagnep．)Ormerod was found for the first time in Tianbaoyan National Nature
Ｒeserve． It was a newly recorded species of Orchidaceae in Fujian Province．

1．2 Morphological characteristics
Saprophytic herb，12 － 15 cm tall． Ｒhizome stout，short，fleshy，yellowish white． Stem erect，stout，pur-
plish red，leafless． Ｒaceme 3 － 7 cm long，several to more than 10-flowered，with pubescent on the rachis;flo-
ral bracts ovate，purplish red，outer surface pubescent，apex acuminate． Flowers erect，not resupinate;sepals
purplish red with pubescent on the outer surface;petals purplish red，linear lanceolate，1-veined，apex acute;
labellum deep yellow，T-shaped，somewhat Y-shaped with apical part conspicuously incised-erose at margin，
claw 8 mm long;hypochile slightly dilated，concave-saccate，aseptate，containing 2 sessile，domed calli at the
base;gynandrium short，with 2 sub-square，lamellate wings;anther ovoid，ca． 2．5 mm，apex acuminate;ros-
tellum erect，furcately 2-lobed (Fig． 1)． Flowering period:September． Fruit was not seen．
1．3 Geographical distribution and habitat
This species has been found in China，Japan，Thailand，and Vietnam until now［1，3 － 4］． China:Motuo
County，Tibet;Baishuiling Tropical Forest Ｒeserve，Hainan;Hekou County，Yunnan;Yuanbao，Guan-
gxi［1，5 － 6］;and Tianbaoyan National Nature Ｒeserve in Fujian Province． The natural habitat of this species is
wet，so it often grows under evergreen broad-leaved forest in its new found habitat in Fujian Province with alti-
tude 763 m，latitude N 25°5651． 11，longitude E 117°330． 96 ． The voucher specimens were preserved in
Herbarium of Fujian Agriculture and Forestry University． Number:090922113，Gatherer:Shi-pin Chen，Time:
Sep． 22，2009． There are also other orchids distributing around the habitat of Odontochilus poilanei，such as
Anoectochilus setaceus，Cleisostoma paniculatum，Goodyera velutina，Hetaeria abbreviatus etc．

2 Discussion
2．1 Taxonomic treatment
It has been contentious about which genus the Odontochilus poilanei belongs to Chamaegastrodia Makino ＆
F． Maekawa is charactered by leafless，holomycotrophic，lip usually 3-partiteand T-shaped，or rarely entire，
ovate with unlobed apex，and column stout，ventrally with 2 triangular-falcate appendages (wings)toward a-
pex［1］． Ormerod［7］ delineated Odontochilus poilanei was a leafless member of Odontochilus Blume rather than a
true member of Chamaegastrodia［8］，because its flowers had a relatively large，long clawed lip and a pair of ven-
tral appendages beneath the stigma，showing a closer relationship to some species of Odontochilus，such as O． el-
wesii C． B． Clarke ex f． Hook．，than to those of Chamaegastrodia． Tian et al［6］ firstly described Ch． nanlingensis
H． Z． Tian ＆ F． W． Xing in 2008． They indicated that it was similar to Ch． poilanei (Gagnepain)Seidenfaden ＆
A． N． Ｒao，with Ch． nanlingensis having smaller flowers，a yellow lip without a pair of elongate introrse lobules at
the epichile lobe，a slightly erose margin，and much smaller dorsal sepals and petals． Hu et al［5］ reported
Chamaegastrodia as a newly genus recorded in Hainan Province represented by Ch． poilanei (Gagnep．)Seidenf．

Ming-he Li et al:Odontochilus poilanei (Gagnep．)Ormerod，a newly
recorded species of Orchidaceae from Fujian Province
et． A． N． Ｒao． Hsu et al［9］ stated briefly that Ch． nanlingensis H． Z． Tian ＆ F． W． Xing had the characteristics
that pointed out by Ormerod． They also proposed Odontochilus guangdongensis T． C． Hsu ＆ S． W． Chung as a
new name for Chamaegastrodia nanlingensis H． Z． Tian ＆ F． W． Xing，because the name Odontochilus nanlingen-
sis (L． P． Siu ＆ K． Y． Lang)Ormerod already existed［1］，but O． guangdongensis T． C． Hsu ＆ S． W． was substi-
tuted by O． guangdongensis S． C． Chen，S． W． Gale ＆ P． J． Cribb in Flora of China［1］．
2．2 Future directions
Chen et al［1］ supported the view that Chamaegastrodia poilanei and Ch． nanlingensis should belong to Odon-
tochilus on the basis of the similar of lip and gynandrium in Flora of China，which was proposed by Ormerod and
Hsu． Meanwhile，Chen et al［1］ also stated briefly that leafless and saprophytic were one of the important charac-
teristics of Chamaegastrodia，which was also accepted by Tian et al and Hu et al． The cytology and molecular bi-
ology should be done in the further researches to make clear the genetic relationship between Chamaegastrodia
and Odontochilus as well as which genera O． poilanei and its sibling species O． guangdongensis should belong to．
3 Conclusion
According to the conclusion of Ormerods research，the species newly recorded in Fujian Province was pub-
lished after the name of Odontochilus poilanei (Gagnep．)Ormerod．
