Abstract

Gastrochilus xizangensis, a new species of Gastrochilus from Xizang, China, is described and illustrated based on morphological characters and DNA evidence. Morphological comparisons indicate that the new species G. xizangensis is highly similar to G. raraensis , G. deltoglossus and G. setosus, from which it differs by its lip with two ridges ranging from spur into central part, ridges with dense short hairs, lip margins membranous and white, sparsely with short hairs.

Abstract

A new species, Uncifera motuoensis (Orchidaceae: Epidedroideae: Aeridinae) from Xizang Autonomous Region, China is described and illustrated with detailed photos and scientific illustration. Detailed morphological comparisons indicate that U. motouensis is similar to U. obtusifolia, but differs in having entire mid-lobe of lip, narrower leaf blade and wider pollinarium stipe. For the identification, a key to the known seven species of Uncifera is presented.

Diagnosis: Uncifera motuoensis is similar to U. obtusifolia Lindl. (1958), but differs in having an entire mid-lobe of lip (vs. trilobe), narrower leaves (linearoblong vs. obliquely oblong) and wider pollinarium stipe wings (leglike vs. cuplike at closing) (Table 1).

Etymology: The species epithet is named after the type locality, Motuo County.

[Botany • 2023] Kuhlhasseltia motuoensis (Orchidaceae: Orchidoideae: Cranichideae) • A New Species from Xizang, China

Kuhlhasseltia motuoensis  

in Ye, Li, Tian, Lin et Jin, 2023. 

DOI: 10.11646/phytotaxa.626.2.9

There are about 11 species of Kuhlhasseltias around the world, including two species found in China. The difference between Kuhlhasseltia motuoensis and other species of Kuhlhasseltia is obvious. The middle part of the lip of the new one is yellow, with two rows of toothed protrusions on each side of its outer edge. Small lobes on the front lip are nearly circular, and there are green spots between the two lobes.

A research team has discovered a new species of orchid in Metog county of the Xizang autonomous region.

The team confirmed that the species, found in August, is new. It was named Kuhlhasseltia motuoensis — "motuo" being the Mandarin name of the county in where it was discovered. The survey result was published in the Journal of the International Association for Plant Taxonomy.

According to Jin Xiaohua, a researcher at the Chinese Academy of Sciences' Institute of Botany, the latest survey shows that there is only one wild population of Kuhlhasseltia motuoensis, with approximately 25 plants, that has been discovered.

Located at the foot of the Himalayas, Metog is a global biodiversity hot spot because of its altitude, which spans many different climate and vegetation zones, Metog has a unique and rich ecosystem, and is favorable to the growth of orchids.

Abstract

Habenaria qinghaiensis, a new species of Orchidaceae from Qinghai Province, is described and illustrated. Molecular phylogenetic analysis based on nuclear ITS (nrITS) and two plastid (matK and rbcL) DNA markers indicates that H. qinghaiensis belongs to H. josephi group (sect. Diphyllae s.l.). It is morphologically similar to H. josephi and H. tibetica, but differs from the former by having petals shallowly 2-lobed at base, lateral lobes of lip 1.8–2.2 cm long, lip with cushion-like appendage at entrance of spur, and from the latter by having almost glabrous bracts, petals and ovary, lip with cushion-like appendage at entrance of spur, and three stigmas.
