Ardisia sharoniae Manjato, Ravololoman.& Razakamal. and A. vohimenensis Manjato, Ravololoman. & Razakamal. (Primulaceae) are described as new species from southeastern Madagascar, the former from the Ankarabolava and Agnakatrika forests (Atsimo-Atsinanana Region) and the latter from the Vohimena range (Anosy Region). They differ from the four currently recognized Malagasy species of Ardisia Sw. by their leaves with serrate margins and their striking angulate twigs. The two new species differ from one another in several characters of their leaves, inflorescences, and fruits. An illustration and a distribution map are provided for each species. Preliminary assessments of the risk of extinction following the IUCN Red List categories and criteria indicate that both are Endangered. An identification key to the seven species of Ardisia occurring in Madagascar is presented.

Odontochilusputaoensis, a new species of Orchidaceae, is described and illustrated from Putao Township, Kachin State, Myanmar.Odontochilusputaoensisis close toO.duplex, but can be easily distinguished from the latter by having a light yellow lip, a bisaccate hypochile with a small, erect, blade-like and emarginate callus within each sac, a mesochile with a pair of dentate-pectinate flanges and a bilobed epichile with a pair of widely diverging lobes that are erect and concave. An identification key to the Southeast Asian species ofOdontochilusand colour photographs ofO.putaoensisare provided. A preliminary conservation assessment according to the IUCN Red List Categories and Criteria is given for the new species.

Allium shahinii, a new species of Allium sect. Scorodon, is described and illustrated from Erzincan Province, Eastern Turkey. It is a narrowly distributed geophyte growing on siliceous screes of warm exposure in mountain ranges of the nemoral and thermophilous deciduous woodland zone, showing close morphological relationships mainly with A. moschatum, A. stocksianum, A. spirophyllum, A. circumflexum but it is clearly differentiated due to perigon, outer tunic, indumentum, leaf and scape characteristics. In this study, diagnostic characters, description, taxonomic comments, photographs, distribution map, detailed illustration, the conservation status of A. shahinii and identification key are provided for A. shahinii and related taxa. According to IUCN Red List Categories and Criteria, A. shahinii is assessed here as a Critically Endangered (CR) species.

Gastrochilus dulongjiangensis, a new species from Gaoligongshan National Natural Reserve, Yunnan, China, is described here. It is morphologically similar to G. pseudodistichus and G. fuscopunctatus, but can be distinguished from them by having the orbicular epichile, hypochile as wide as epichile and fusiform pollinia. A preliminary risk-of-extinction assessment shows that the new species should be regarded as Data Deficient (DD) according to the IUCN Red List Categories and Criteria.

Abstract—A new species with verrucose fruits and relatively large leaves, Eugenia antilahimenae, is described from the northeast of Madagascar. It is known from the protected areas of Makira and Masoala in lowland rainforests west and north of the Baie d'Antongil. We provide a detailed description of the species, illustration, a table comparing morphologically similar taxa, and preliminary assessment of the risk of extinction following the IUCN Red List Categories and Criteria, which indicates a status of “Least Concern.”
