Journal of Tropical and Subtropical Botany
The genus, Phreatia, is about 190 species,
distributed from Sri Lanka and mainland Asia,
through SE Asia, to Australia, New Guinea, and the
Pacific islands, most species occurring in Indonesia
and New Guinea[1]. This genus is characterized by
having mentum, lip often with a basal claw attached
to the end of column foot, base concave or saccate,
and 8 waxy pollinia in 2 groups of 4, attached by a
narrow caudicle to a small viscidium[1–5].
Oberonia is a genus of about 150 – 200 species,
centered in tropical S and SE Asia but extending to
tropical Africa, Madagascar, the Mascarene Islands,
the Philippines, New Guinea, NE Australia, and the
SW Pacific islands across to Tahiti[6]. This genus is
characterized by its fleshy leaves, small flowers often
in whorls, petals often narrower than sepals, and four
waxy pollinia cohering in 2 unequally sized pairs[4–7].
Recently, during our botanical trips to Xizang
(Tibet) and Yunnan, two little known species of these
two genera from China were discovered.

摘要： 报道了中国兰科二新记录种：小馥兰(Phreatia elegans Lindl.)，其主要特征是萼囊囊状，花梗和子房波状弯曲，唇瓣有爪与
蕊柱足相连，唇盘有毛；镰叶鸢尾兰(Oberonia falcata King et Pantl.)与 O. angustifolia Lindl. 类似，但本种的唇瓣明显三裂，中裂

Abstract: Phreatia elegans Lindl. and Oberonia falcata King et Pantl., two new records of Orchidaceae from
China, are reported. Phreatia elegans is characterized by its saccate mentum, slightly curved pedicel and ovary,
clawed lip with hairy disc; Oberonia falcata resembles O. angustifolia in having well-developed stems, but differs
from it by having clearly 3-lobed lip, bifid middle lobe.
Key words: Phreatia elegans; Oberonia falcata; Orchidaceae; New record; China

many flowered, with 3 – 5 tubular sheaths. Bracts
lanceolate, 3 – 5 mm long. Flowers white. Pedicel
and ovary slightly curved, 3 mm long. Dorsal sepal
broadly ovate, 1-veined, ca. 2 mm long, 1 mm wide;
lateral sepals oblique, triangular, 1-veined, ca. 2 mm
long, 1.7 mm wide; petals 1-veined, ovate, ca. 1.5 mm
long, 1 mm wide; lip clawed, disc semi-orbicular,
hairy, 2.5 mm long, 1.5 mm wide; mentum saccate,
1 mm long; column truncate, with two horns at apex,
1 mm long.
There are 5 (2 endemic) species of Phreatia
in China besides this species[1]. Phreatia elegans is
a distinct species and readily distinguished from its
relatives by having more or less pseduobulbous stems,
clawed and hary lip, truncate column with two horns
at apex.
Distribution: China, India, Indonesia.
China: Xizang, Motou, Beibeng, 1100 m，in
the tropical forest. 2010 – 08 – 05, STET 2136 (PE!).
Conservation Status: Although Phreatia
elegans is widespread from India to Indonesia, there
are very few records in the field. Thus, we temporarily
consider this species as DD according to IUCN Red
list Categories and Criteria[8].

Fig. 2.
Epiphytic plant. Stem 10 – 15 cm long. Leaves
laterally compressed, linear-lanceolate, falcata,
acuminate, 4 cm long, 2 mm wide, sheathing but not
jointed at base. Inflorescence 10 – 11 cm long, densely
many flowered. Flowers greenish white. Bracts
lanceolate, longer than ovary and pedicel, margins
wavy and dentate. Ovary and pedicel 2 mm long.
Dorsal sepal ovate, slightly concave; lateral sepals
ovate, slightly oblique and concave, 0.8 mm long,
0.5 mm wide; petals oblong, apex truncate, 0.7 mm
long, 0.2 mm wide; lip oblong, 3-lobed, 1.5 mm long,
0.9 mm wide; side-lobes falcata, 0.2 mm long; mid-
lobe bifurcate, lobelets 0.4 mm long, acute; column
0.3 mm long; anther cap oblong, apex acute.
There are 34 (11 endemic) species of Oberonia
in China including this species[3]. Oberonia falcata
resembles O. angustifolia Lindl. in having well-
developed stems, but differs from it by having clearly
3-lobed lip, bifid middle lobe[2,9].
O. falcata, in fact O. japonica, was mistakly
recorded in Taiwan[10], and there are no more exact
informations about this species growing in Taiwan.
Distribution: China, Bhutan, Cambodia, India,
Thailand, Vietnam.
China: Yunnan, Gongshan, epiphytic on tree
along the river, 1400 m, DLJ-ET (Dulongjiang
Expedition Team) 0834 (PE!); Jin X. H. 9584 (PE!).
Conservation Status: This species is endemic
in the subtropical forest and grows under the nature
forest. However, due to the growing population in
this region, subtropical forest is decreasing greatly.
Therefore, we consider this species as ‘Critically
Endangered’(CR), according to IUCN Red List
Categories and Criteria[8].
