Many Cypriot plant species are threatened with extinction, urging conservation action. This study aims to assess the progress made so far in the ex situ conservation of threatened plants of the flora of Cyprus, to identify gaps and to set priorities for future activities. The criteria taken into account for the analysis were: (1) IUCN threat category; (2) regional responsibility; (3) legal responsibility; (4) number of known locations; (5) number of known locations with ex situ conservation; (6) number of accessions of unknown collecting location; and (7) occurrence within protected areas. In total, 158 of the 263 threatened taxa (60.08%) have at least one accession in conservation. The percentage of locations from which there are accessions conserved, compared to the total number of known locations is low (24.20%). Only 17.49% of the threatened taxa have accessions conserved from all known locations and are, therefore, effectively conserved ex situ. The percentage of threatened taxa conserved ex situ is lower than the target of 75%, set by the Global Strategy for Plant Conservation (GSPC) Target 8 (CBD 2012), urging additional conservation action. A priority list of threatened species has been established, which can be used as a tool for future planning of conservation activities.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"31 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139506791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aulomyrcia (Myrtaceae) is described and illustrated. Myrcia bahiensis Gaem & Mazine can be distinguished from all its congeners by large leaf blades bearing longitudinal, curved marks that indicate a plicate ptyxis, in combination with glabrous inflorescences, inconspicuous bracts, large flower buds, and a ‘hyper-hypanthium’ floral developmental pathway. Within the Marlierea group, vegetative morphological traits of Myrcia bahiensis most resemble those of Myrcia sucrei, whereas its reproductive organ morphology recalls M. neoregeliana. However, M. sucrei has densely tomentose inflorescences and showy bracts while M. neoregeliana has smaller leaves without longitudinal marks, indicating a planate ptyxis. Myrcia bahiensis is known from only one collection made in the cacao region of southern Bahia, Brazil. Due to a lack of reliable geographical distribution information, the new taxon is provisionally assessed as Data Deficient according to the IUCN criteria. An identification key for all species of the Marlierea group occurring in the Atlantic Forest of Bahia state is provided.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"10 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139507023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple phylogenetic inferences using molecular data recover the genus as sister to a clade comprising mycoheterotrophic Thismiaceae and the photosynthetic family Taccaceae, contrary to earlier placements of Afrothismia and Thismiaceae within Burmanniaceae. Morphological support for separating Afrothismia from the rest of Thismiaceae has depended on the zygomorphic flowers of Afrothismia (although some species of Thismia are also zygomorphic), and their clusters of root tubers, each with a terminal rootlet. The number of described species of Afrothismia has recently increased from four to 16, with seven more species as yet undescribed; these discoveries have added morphological characters that support its distinction from Thismiaceae. Most notably, the ovary in Afrothismia has a single stalked placenta, and circumscissile fruits from which seeds are exserted by placental elevation (vs in Thismiaceae, three placentas, a deliquescing fruit lid, and seeds not exserted). Afrothismia stamens are inserted in the lower part of the floral tube, where they are attached to the stigma, and individual flowers are subtended by a single large dorsal bract. In contrast, in Thismiaceae, stamens are inserted at the mouth of the tube, free of and distant from the stigma, and each flower is subtended by a loose whorl of (2 –) 3 (– 4) bracts. Here we formally characterise Afrothismiaceae and review what is known of its development, seed germination, interactions with mycorrhizal Glomeromycota, biogeography, phylogeny and pollination biology. All but one (Afrothismia insignis; Vulnerable) of the 13 species assessed on the IUCN Red List of Threatened Species are either Endangered or Critically Endangered; one species (A. pachyantha) is considered extinct.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"21 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138543661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
