Flower yellow or yellow green, with dark brown or purplish spots. Sepals similar, oblanceolate, 6.8-7.0 × 3.2-3.5 mm, base contracted, apex obtuse. Petals oblanceolate, 6.2-6.5 × 2.3-2.5 mm, apex obtuse.

Now that fresh material has been collected in north Myanmar, a detailed description of the species, including the leaf and flower colour, leaf apex shape and features of pollinia, anther cap and rostellum, are provided here. Morphologically, it is closely related to G. pechei in having the sub-triangular epichile of the lip and hypochile of the lip laterally not compressed. However, it can be easily distinguished from the latter by the small stature of the plant (leaves less than 15 cm), green or yellow green flowers, oblanceolate sepals and petals, epichile triangular without central cushion (Kuntze 1891; Rao 1992).</p> </div>	https://treatment.plazi.org/id/795AA3DAA5C75522A7DF5B43DCF792E9	Public Domain	No known copyright restrictions apply.

Natma Taung (Mt.Victoria) National Park, 2900 m a.s.l., epiphyte on the trunk of Alpine Rhododendron forests, 30 Apr 2017, Yun-Hong Tan M1271 (HITBC!).</p> <p>Note.</p> <p>Only a single specimen and illustration of this species previously existed, on which the original description was based (Das and Chanda 1988). Foliar and floral characteristics were not described in sufficient detail in the original description, due to the extremely poor state of the preserved specimen and it was not possible to conduct a detailed study on this species. Now that fresh material has become available, a detailed description of the species has been provided here. On the basis of the long and pendulous stem, G. corymbosus can be placed in section Microphyllae (Tsi 1996). This species exhibits great variation between populations in leaf shape from falcate-lanceolate to oblong (Figure 2 C). Morphologically, it shows a close affinity to G. distichus (Lindley) Kuntze, but differs from the latter by having much shorter (less than 15 cm) and stout stem, apex of leaf unequally 2-lobed without awns, inflorescences corymb with 4-6-flowers, epichile of lip with a slightly diamond shaped central cushion, margin entire or slightly denticulate, emarginate at apex (Das and Chanda 1988; Chen et al. 2009).</p> </div>	https://treatment.plazi.org/id/0D30E0A88B7B57989BBA9AC0F91ED2E2	Public Domain	No known copyright restrictions apply.

Here in the manuscript, we have confirmed the occurrence of this species in north Myanmar in the Naungmeng town, Putao county, Kachin state. It was growing epiphytically on the trunk of riparian trees in tropical rainforest which is dominated by Dipterocarpus obtusifolius Teijsm. ex Miq. (Dipterocarpaceae).</p> <p>Additional specimens examined.</p> <p>MYANMAR. Kachin State. Putao County, Naungmeng town, tropical forest, 700-800 m a.s.l., epiphyte on the trunk of riparian trees, 8 August 2017, Qiang Liu 470 (HITBC!).</p> <p>Note.</p> <p>Gastrochilus pechei was only known from the type specimen until recently and, because this specimen was poorly preserved and severely shrunk, the key morphological characters of this species, such as flower colour and shape, were hard to interpret. As far as we can tell, there had been no subsequent collections of this species since 1889. Now that fresh material has become available, a detailed description of the species, including the plant and flower characters and information of distributed location, habitat and altitude, can be provided here. Morphologically, it shows a close affinity to G. obliquus, G. somai and G. arunachalensis. However, it differs from G. obliquus by having the slightly irregularly erose margin on the epichile, apex of epichile acute and subglobose hypochile (significantly lacerate or erose on epichile margin, apex of epichile obtuse and subglobose-cucullate and laterally compressed hypochile in G. obliquus) (Chen et al. 2009); from G. somai, it can be differentiated on being a large plant (leaves 15-20 × 3.5-4.5 cm), yellow sepals and petals and white labellum, all densely covered with purplish spots (smaller plant (3.5-4.2 × 1.2-1.7 cm), yellow-green sepals and petals without purplish spots and white labellum with yellow blotch on the centre of the epichile in G. somai) (Jin et al. 2010); from G. arunachalensis, by having spathulate sepals and petals, sub-triangular epichile with central cushion and subglobose hypochile (oblanceolate sepals and petals, triangular epichile without central cushion and cupular hypochile in G. arunachalensis) (Rao 1992).</p> <p>Discussion.</p> <p>The orchid flora of Myanmar is highly diverse but poorly known due to very few comprehensive studies. According to our current knowledge, about 800 orchid species are distributed in Myanmar (Kurzweil and Lwin 2014), but this is probably an underestimate. Many new distribution records and new species have been published in the last few years (Aung et al. 2017; Liu et al. 2017, 2018; Yang et al. 2017; Aung and Jin 2018, Zhou et al. 2018).</p> <p>Although the genus of Gastrochius is small, it is easy to be confused with other taxa of Aeridinae when it is without flowers and is also difficult to be identified within species even during the flowering period. So, many species may be misidentified as other taxa. Meanwhile, Myanmar lies in southeast Asia, with the northern part bordering with southwest China and India and the southern part connecting with Thailand, all of these regions being rich in species of Gastrochilus. Therefore, we believe that more and more species of Gastrochilu s will be found when undertaking further field investigations and systematic studies.</p> </div>	https://treatment.plazi.org/id/BDDBE059794C56D1B8DC09F6F985599B	Public Domain	No known copyright restrictions apply.
