“…Species were assessed by staff members at Papua New Guinea Forest Research Institute, who were able to include their own knowledge and expertise in assessments as well as information from additional sources. These sources included notes from Herbarium records at LAE or from GBIF; species entries in Trees of Papua New Guinea (Conn & Damas, 2006); primary literature and online resources such as Useful Tropical Plants (Fern, 2014) and Lesser Used Species pages (tropicaltimber.info, 2022). Threats were often identified from the assessor's knowledge of the local region and additional evidence was provided from Global Forest Watch (World Resources Institute, 2022) and GoogleEarth (2019+).…”

Papua New Guinea has a diverse tree flora. Now for the first time we know that 460 (36%) of its endemic tree species are threatened with extinction in the wild. These trees require immediate conservation action, through a variety of methods. Protection of trees is essential in Papua New Guinea as many people across the country rely on them for their livelihoods. Additionally, the extinction of these species would mean the loss of unique biodiversity. With the majority of forest cover still remaining in Papua New Guinea, it presents an almost unique opportunity to save tree diversity at a large scale and should therefore be at the forefront of the conservation agenda. Summary• Papua New Guinea is one of the world's most tree diverse countries, with over 1,200 endemic tree species. However, forests within the country face a range of threats but the impact of these threats on individual tree species has yet to be studied. Without identifying which species are threatened, where they are and their major threats it is not possible to effectively prioritise conservation actions for the trees of Papua New Guinea.

“…The most comprehensive account pertinent to New Guinean Syzygium, by Hartley and Perry (1973), enumerated 138 species with many taxa unaccounted for, listed at the end of their monograph. Many novelties subsequently have since been discovered and described for New Guinea (see Conn and Damas 2015;Hambali et al 2017;Snow 2010;Takeuchi 2002Takeuchi , 2015, mainly from Papua New Guinea. Recently, a comprehensive specialist-verified checklist of New Guinean vascular plants enumerated 207 Syzygium species, the largest tree genus recorded for the island (Cámara-Leret et al 2020).…”

“…More collecting trips were conducted in surrounding areas, either during the same period or on separate explorations in 2018, and no other morphologically similar individual has been encountered. A thorough herbarium study of collections at BM, BO, CNS, K, MAN, and SING (herbarium abbreviations follow Thiers 2020-continuously updated), as well as surveys on published literature of New Guinean Syzygium (Conn and Damas 2015;Diels 1922;Greeves 1923;Hartley and Craven 1977;Hartley and Perry 1973;Merrill and Perry 1942;Ridley 1916;Snow and Craven 2010;Takeuchi 2002Takeuchi , 2015Warburg 1891) accompanied by type examinations, failed to match the Oransbari taxon to any of the named Syzygium taxa for New Guinea. Hence, we concluded that the Oransbari taxon is an undescribed species closely related to Syzygium longipes (Diels) Merr.…”

Syzygium oransbariense Mustaqim, Y.W.Low & Heatubun (Myrtaceae) is here formally described. This species is found in the lowlands on the eastern flank of the Arfak Mountains, Bird’s Head Peninsula, western New Guinea. The species is similar to Syzygium longipes (Diels) Merr. & L.M.Perry but differs based on a set of diagnostic morphological characters. Species description, distribution, a preliminary conservation status assessment, and notes on the new species are presented here.

Syzygium (Myrtaceae): Monographing a taxonomic giant via 22 coordinated regional revisions

Syzygium Gaertn. is the largest woody genus of flowering plants in the world. Unpublished but extensive recent herbarium surveys suggest 1200‒1800 species distributed throughout the Old World tropics and subtropics (Table 1). Until recently, Syzygium exemplified a recurring taxonomic impediment among megadiverse genera, wherein few taxonomists worked on the group in any sustained manner, a majority of the herbarium specimens remained undetermined or misidentified, few if any attempts were made to look at the genus globally, and limited or no molecular studies were available to provide a predictive phylogenetic context of the genus. The situation with Syzygium has slowly begun to change as allied genera have been absorbed into the genus (Biffin et al., 2006; Craven & Biffin, 2010), and predictive phylogenetically-based infrageneric classifications are emerging. Taxonomic outputs on Syzygium also have been increasing across its range with the description of new species, resolution of nomenclatural and typification issues, and some regional revisions being initiated or updated. However, virtually all regional treatments (which some areas lack) need urgent revision because they are severely outdated, have limited molecular sampling and are error-ridden. We are coordinating a genus-wide taxonomic update of Syzygium through a series of 22 regional revisions, including 9 in the Flora Malesiana region (Figure 1). Each treatment will include a phylogenetic framework with species descriptions, type information, synonymy, distributions, ecological notes, and keys. Field images (Figure 2) and/or line drawings will be included with the goal of every species being illustrated. This working group has been formed to encourage a coordinated effort to document this unwieldy taxonomic giant and regional botanists working on the group are encouraged to be involved. A robust taxonomy of the genus is a prerequisite for testing the many complex questions about evolution and ecology that Syzygium could help address.
