Abstract: Morphological comparisons indicate that Tainia emeiensis (K. Y. Lang) Z. H. Tsi, previously recorded
as endemic to Sichuan, China is conspecific with T. macrantha Hook. f. and reduced as a heterotypic synonym.
Key words: New synonym; Orchidaceae; Tainia; Tainia emeiensis; Tainia macrantha
Tainia Blume is an orchid genus in the subfamily
Epidendroideae, tribe Collabieae[1]. There are about
30 species, distributed from India, Sri Lanka and the
Himalayan region, north to China, Japan, south from
SE Asia to New Guinea and the Pacific islands[2]. In
his revised monograph, Turner[3] regarded Ania Lindl.
and Mischobulbum Schltr. distinct from Tainia based on
morphology. Despite that, most of these species have
long been treated under Tainia s.l. including Ania,
and sometimes also including Mischobulbum[1–2,4–5].
In the most recent classification based on molecular
phylogeny[6–9], Ania was separated from Tainia s.l.
and re-established. Currently only 22 of these were
previously recognized species, the rest being proposed
as species of Ania.
Whilst examining herbarium collections of this
genus for a revision of Tainia and its allies, the types of
T. emeiensis (K. Y. Lang) Z. H. Tsi and T. macrantha
Hook. f. were found morphologically very similar
(Fig. 1). Lang[10] reported Mischobulbum emeiense
based solely on type specimens collected from Emei Shan
(Mount Emei) in central Sichuan Province, China. Then
Tsi[5] transferred M. emeiense to Tainia. In the original
description, the author specified it differs from T.
macrantha in having rounded leaf base, bigger sterile
bract, less and smaller flowers, and scarcely or slightly
lobed lip. These characters, however, are not sufficient
to recognize T. emeiensis as a species distinct from T.
macranthe. It should be noted that the holotype of T.
emeiensis was collected while the flowers were still in
第5期 493翟俊文等：兰科带唇兰属一新异名
bud. After dissecting fresh flowers of T. macrantha,
we confirmed that the shorter inflorescence, larger
sterile bracts, smaller flowers, and not conspicuous
lateral lobes of lip are all coincident with those of
flowers of T. macrantha in bud.
Other than the type specimens, no additional
specimen of this species has ever been collected
until recently it was found in Gulin Xian, Sichuan
Province. Not surprisingly, the species differs from
the original description in its larger flowers and

494 第23卷热带亚热带植物学报
conspicuous lateral lobes of lip. Moreover, based on
further investigations of herbarium specimens, we
concluded that the shape of the leaf base, as well as
the floral characteristics of T. emeiensis falls well
within the variation range of T. macrantha, e.g., some
individuals are subrounded in their leaf base, while
some others are cuneate or truncate; inflorescence
3-flowered, also 6-flowered. It becomes evident that
the two species are conspecific and T. emeiensis is
therefore treated as a synonym of T. macrantha.
