Eight new species of Hymenochilus from Australia are described and illustrated. Six of the new species have affinities to (and are here compared with) H. cycnocephalus: H. anemophilus, H. calcicola, H. cymbellus, H. longipes, H. nemoralis and H. pachylus. Hymenochilus anemophilus is shorter (2–8 cm), with dark green strongly veined rosette leaves, crowded dark green flowers, oblong to obovate labellum lamina and, a broader blunter beak on the labellum appendage; H. calcicola is shorter (3–12 cm), crowded green flowers with prominent dark green stripes, ovate petals with a strongly developed basal flange on the anterior side and narrow elliptic labellum lamina with a broad pointed beak on the labellum appendage; H. cymbellus differs by its sparser basal rosette with narrower rosette leaves, thinner scapes, flowers with distinct darker green stripes and shallowly saccate lateral sepals that narrow inwards to a distinctly pointed apex; H. longipes differs by its thin-textured rosette leaves, widely spaced darker green flowers with darker green veins, elliptic-obovate labellum lamina and a longer labellum basal appendage which protrudes prominently from the flower in side view; H. nemoralis has longer rosette leaves, thicker scape and darker green flowers with prominent narrow dark green stripes; H. pachylus has thicker rosette leaves, taller, thicker scape, flowers prominently striped, elliptic-obovate labellum lamina and labellum appendage with a short thick beak. Two of the new species have affinities (and are here compared) with H. muticus: H. pagophilus and H. pisinnus. Hymenochilus pagophilus differs by its moderately crowded to crowded flowers, broader, shinier flowers and rectangular-obovate labellum and H. pisinnus differs by its smaller rosette with smaller, narrower leaves, thinner scape, smaller flowers, that are often on long pedicels, shorter, shallowly saccate lateral sepals, smaller rhomboid petals and, smaller obovate labellum. In addition, Hymenochilus cycnocephalus and H. muticus, are characterised in the strict sense with full descriptions, distribution, and habitat.
本报告描述了来自澳大利亚的 8 个新 Hymenochilus 物种，并附有插图。其中 6 个新种与 H. cycnocephalus 有亲缘关系（在此与之进行比较）：H. anemophilus、H. calcicola、H. cymbellus、H. longipes、H. nemoralis 和 H. pachylus。Hmenochilus anemophilus 较短（2-8 厘米），叶片呈深绿色，叶脉密集，花深绿色，唇瓣长圆形至倒卵形，唇瓣附属物上有较宽的喙。calcicola 较短（3-12 厘米），密集的绿色花朵上有突出的深绿色条纹，卵形花瓣前侧有发达的基部凸缘，唇瓣薄片狭椭圆形，唇瓣附属物上有宽尖的喙；H.cymbellus 的不同之处在于其基部莲座丛较稀疏，莲座丛叶较窄，花葶较细，花朵有明显的深绿色条纹，侧萼片呈浅囊状，向内收窄，先端明显变尖；H.longipes 的不同之处在于它的莲座丛叶质地较薄，深绿色花朵间距较大，叶脉呈深绿色，唇瓣薄片呈椭圆状倒卵形，唇瓣基部附属物较长，从侧面看会明显突出于花朵；H.H. pachylus 的莲座丛叶更厚，花葶更高、更粗，花上有明显的条纹，唇瓣薄片呈椭圆状倒卵形，唇瓣附属物有短粗的喙。其中两个新种与 H. muticus 有亲缘关系（在此进行比较）：H. pagophilus 和 H. pisinnus。H. pisinnus 的不同之处在于其莲座丛较小，叶片较小，较窄，花葶较薄，花朵较小，通常长在长花梗上，侧萼片较短，呈浅囊状，花瓣较小，倒卵形唇瓣较小。此外，Hymenochilus cycnocephalus 和 H. muticus 也有严格意义上的特征描述、分布和栖息地。

A new species of Pleurothallis from subsection Macrophyllae-Fasciculatae is described and illustrated. The new species is compared with Pleurothallis folsomii from Panama. Pleurothallis celsia is most similar to a group of species with small, yellow flowers but it can be recognized mainly by its lip, which is widely ovate, the surface and margin pilose and papillate, and the base of the glenion densely vesiculose.

Colombia is a major biodiversity hotspot, having one of the richest orchid floras in the world. The country spans over a million square kilometers of land, hosting a multitude of different ecosystems thanks to the complexity of its mountainous systems and influences from neighboring countries in Central and South America, as well as the Atlantic and Pacific coastlines. Prior studies found an estimated 3591–4270 species of orchids occurring in Colombia, making it the most species-rich plant family in the country. About 35% of those orchids are members of the Pleurothallidinae subtribe, the largest group in the family and also that with the highest rate of species discovery. Here we record 1862 species of pleurothallids for the country, a significant increase from the 1286–1529 range estimated just a few years ago. We expect Pleurothallidinae to represent close to half the Colombian orchid flora. Colombia hosts roughly one third of all currently known taxa in the subtribe, and close to 60% of these species are found nowhere else in the world. These are clear indicators that the country is a highly important center of pleurothallid diversity and a key target for their conservation. The most species rich genera in the country are Stelis (521 species), Lepanthes (377 species), Pleurothallis (248 species) and Masdevallia (171 species). Country-level distribution is given for each accepted species. The closest floristic affinity is found with Ecuador, with which Colombia shares over 76% of the non-endemic Pleurothallidinae species, followed in the distance by Venezuela and Peru with just above one quarter of the non-endemics being shared. Numerous new country records are presented in the catalogue, many of which are illustrated with color photographs. We provide a full list of homotypic synonyms for each accepted taxon, as well as an annotated list of excluded taxa and newly proposed synonyms. Heterotypic synonyms are not listed, unless they are based on Colombian material. Typification for each accepted species is presented, with lectotypes, neotypes and epitypes being selected whenever necessary and available, as well as information regarding published illustrations.

Karl Reiche (1860–1929), a German botanist, came to Chile in 1889 as a professor at the Lyceum in the city of Constitución. He was attracted by the country’s climate and its traditional friendliness to German immigrants. A few years later, in 1897, Federico Phillippi, Director of the Museo Nacional de Historia Natural, welcomed Reiche as the new Head of the Botanical Section, a position he held until 1910. During his 21 years in Chile, Reiche worked intensively on the Chilean flora and was a prolific writer. Besides six volumes of the Estudios críticos de la Flora de Chile (1896–1911), several editions of Reiche’s Plant Geography of Chile were published (1907, 1934–1937, 2013), a magnificent essay on Chiles’ Orchidaceae, Orchidaceae Chilensis (1910, reprint 2007), and several other minor works. On Reiche’s suggestion, The Museo Nacional engaged Friedrich Kraenzlin (1847–1934) to write a treatment of the orchids of the Southern Cone that was published in 1904 as the second volume of Orchidacearum Genera et Species, a work that was widely criticized by many botanists, beginning with Reiche himself.

Pinalia elata is an attractive endemic species of Peninsular Malaysia, known from only six localities within the Titiwangsa mountain range where it is confined to montane vegetation. However, four of these localities are now threatened by anthropogenic factors, raising concerns about the ongoing survival of this endemic species in the wild. Despite efforts to understand the conservation status of Malaysian orchid species, there remains much work to be done, particularly for endemic species confined to remote and mountainous areas. Therefore, this paper provides a detailed morphological description, photographic illustrations for easy identification of the species, and a conservation assessment based on the IUCN Classification Criteria. Morphologically, P. elata can be easily distinguished from the other Pinalia species in Peninsular Malaysia by its erect inflorescences with well-spaced, closed flowers along the apical half, subtended by prominently large purplish-brown bracts. The flowers resemble buds with the labellum hidden by the petals and sepals. A preliminary risk-of-extinction assessment categorizes P. elata as critically endangered, CR A2acd C2a(i) D, according to the IUCN Red List Categories and Criteria.

We describe and illustrate a new species of Masdevallia from the Andean-Amazonian foothills of Caquetá, Colombia. Masdevallia leonor-baeziana belongs to Masdevallia subsect. Saltatrices, within the M. constricta group. It is most similar to M. constricta, but it can be distinguished by the shorter sepals and sepaline tails that do not surpass the tube length, and the shorter, sigmoid-ovate lip.

In an expedition of 341 plots across a large elevation (1,100-3,880 m) and spatial gradient (~270 km) in the eastern cordillera we found a new species of the genus Lepanthes in Santuario de Fauna y Flora de Iguaque, Boyaca, Colombia. We propose L. bachue as a new species. It is most similar to L. papallactae but it can be distinguished by its proliferous plants (vs. non proliferous), the petals with the upper lobe 2.5 mm long, the lower lobe 4.5 mm long, larger than the upper one, and the margins fimbriate (vs. lobes subequal, 4.5 mm long and shortly pubescent) and the lip with the blades oblong, sub-sigmoid, adnate to the middle of the column with a short oblong, bifid, yellow appendix hiding in the middle (vs. blades narrowly elliptical-oblong, connate to the column above the middle with a recurved, pedunculate, biglandular appendix). Our large elevational and geographical sampling suggest that the species is geographically restricted and have high habitat specialization, thus urging to protect its natural habitat and population.
作者在哥伦比亚Boyaca地区的Santuario de Fauna y Flora de Iguaque地区对东部科迪勒拉地区341个样地进行了高海拔(1100 ~ 3880 m)和高空间梯度(~270 km)的考察，发现了Lepanthes属的一个新种。我们提出L. bachue为新种。最类似于l . papallactae但它可以区分其发芽的植物(与非增生),上部叶的花瓣长2.5毫米,下叶长4.5毫米,比上一个,状和利润率(与叶几乎相等的,长4.5毫米,青春期的不久)与叶片长圆形,唇sub-sigmoid,贴生的中间列的长圆形,短裂,黄色附录藏在中间(与叶片勉强elliptical-oblong,合生于中间以上的柱具一弯曲的，有花序梗，大叶附属物)。大量的海拔和地理采样表明，该物种在地理上受到限制，生境专业化程度高，因此迫切需要保护其自然栖息地和种群。
