全 文 ：During the botanical investigation in Nabanhe
River Watershed National Nature Reserve of Yunnan
Province in 2011, a species of Aneoctochilus was
found. It bloomed in Feb. 2012 in greenhouse of
East China Normal University. Based on a careful
morphological examination, it was identified as
Aneoctochilus lylei Rolfe ex Downie, a new record to
Chinese flora[1–7].
The genus Anoectochilus Blume (Goodyerinae,
Cranichideae, Orchidaceae)[1], excluding Odontochilus
Bulme containing about 30 terrestrial Orchids is
distributed from India and the east Himalayas, through
south and southeast Asia to Australia and the southwest
Pacific islands. There are 11 species (7 endemic) in
China[2]. It is characterized by the ornate foliage, two
stigma lobes, spur of labellum with a septum and two
calli[3].

Abstract: Anoectochilus lylei Rolfe ex Downie is newly reported to Chinese flora. The detailed morphological
descriptions and photoes are also provided. This species is characterized by the white “Y”-shaped lips, epichiles
lobes linear-oblong, mesochile with 1–3 short irregular denticles and the spur with 2 peltate calli inside.

brown with pale apexes; dorsal sepal ovate, 6–7 mm
long; lateral sepals ovate-oblong, 7–11 mm long,
shortly acute. Petals obovate, as long as dorsal sepal,
strongly oblique, adhering closely to dorsal sepal to
forming a hood. Labellum Y-shaped, spurred, white,
15–22 mm long; epichile bilobed, lobes diverge an
acute angle, lanceolate, tapering, 8–10 mm long, 1.2–
3 mm wide; mesochile with short claw, along flanges
slightly erose or with 1–3 short irregular denticles;
hypochile quadrate with 2 green oblong spots in
the central area, 2 mm long; spur cylindric, directed
parallel with ovary, 4–5 mm long, with 2 large peltate

calli inside. Column 3–5 mm long, at front with 2 sub-
triangular, acute wings, not entering to the spur and
short bifid rostellum. Stigma 2， at lateral side. Anther
cap ovate acuminate, reddish-brown, 4 mm by 3 mm.
Pollinia 2, obliquely clavated, yellow, 4 mm long,
attached to a solitary viscidium. Ovary with pedicle
10–16 mm long, 2 mm diameter. Fl. Nov.–Feb.
Distribution: China (Yunnan); Vietnam (Dak
Nong, Gia Lai, Khanh Hoa, Kon Tum, Lam Dong,
Quang Tri); Thailand (Mê Awn, Salaeng Haeng-Thung
Samo, Nam Phrom)[5,7].
Anoectochilus lylei usually lives in closed humid
broad-leaved forests on silicate soils and has been
recorded to be native to Vietnam and Thailand. The
locality in Nabanhe River Watershed National Nature
Reserve, Jinghong, Yunnan, is quite similar in climate
and geography to those of neighboring Vietnam and
Thailand and shows Typical Asian distribution[8].
Etymology: We choose this Chinese name
according to the transliteration of its specific epithet as
well as the breathtaking beauty of the buds and flowers.
Specimens examined: China: Yunnan Province,
Jinghong, Nabanhe River Watershed National Nature
Reserve. Jul. 9th 2011, Hu Chao B21 (HSNU).
Thailand: Mê Awn, east of Chiengmai 750 m, Jan.
1912, Kerr 297 (K, Photo!).
Taxonomic discussion: Anoectochilus lylei
is similar with A. roxbughii but can be easily
distinguished in having lanceolate to broadly-lanceolate
shaped epichile lobes, fewer and shorter denticles along
the mesochile claw and earlier flowering phase. A. lylei
also shows close resemblance with A. brevilabris, but
differs in having narrowly-cylindrical and longer (more
than 4 mm) spur, 4–5 times as long as broad epichile
lobes and also insignificant denticles on epichile[5].
Conservation status: Anoectochilus lylei is rare
in the wild (3 individuals as we discovered). According
to the IUCN Red List Categories and Criteria[9], A. lylei
should be treated as Critically Endangered (CR). The
species of Anoectochilus are indoor ornamental plants
known as ‘Jewel orchids’ because of their attractive
foliar venation. Some of them have long been used as
valuable ingredients in traditional Chinese medicines,
such as A. roxburghii and A. formosanus[10]. Though
there is no medical use of Anoectochilus lylei reported
until now but considering its ornamental value and
sparse distribution, the environmental protection seems
to be urgent.
