“…The compilation of and comparison with previously published preliminary assessments 6,13,27,28,[30][31][32][34][35][36][38][39][40][41][42][43][44][45][46] indicate numerous changes of assigned threat categories in the current assessments (Fig. 3).…”

“…Collections from this field work have clarified distributions of numerous species that were originally described from very limited material, e.g. Begonia ozotothrix was described from a few collections from limestone forest on the eastern arm of Central Sulawesi 31 , but is now known to be widespread on the island (EOO > 84,000 km 2 ) and to also occur on granite and alluvial substrates (Supplementary Information Table 3 ); B. flacca was only known from a few historical collections 35 , but is now known to be widespread in Southeast Sulawesi (EOO > 16,000 km 2 ); B. hooveriana was described from a single, strongly disturbed urban locality 33 , but is now known to have an EOO of more than 10,000 km 2 . This indicates that the current collection density allows to effectively identify taxa that are more widespread on the island.…”

Species conservation assessments using the criteria outlined by the International Union for the Conservation of Nature Red List can be compromised by limited data availability. Species-rich tropical plant taxa with numerous microendemics are particularly problematic. This study focusses on the Begonia flora of the Indonesian island of Sulawesi, comprised of 65 herbaceous species mainly found in rainforest habitats. Sixty-two species are Sulawesi endemics, including 20 species restricted to limestone karst landscapes. Forty-eight species are represented by fewer than 10 herbarium collections. Here, we outline and discuss an approach that, despite these data limitations, allows meaningful conservation assessments by integrating analyses of occurrences, data primarily based on remote sensing approaches, including forest landscape integrity, forest cover loss, and land cover, and extent of suitable habitat estimation. The results indicate that most Sulawesi Begonia species are narrow endemics whose rainforest habitats have substantially deteriorated in the last two decades: 27 species are assessed as Critically Endangered, 24 as Endangered, six as Vulnerable, five as Least Concern, and three species are Data Deficient. Conservation action, including extension of the protected area network in Sulawesi with emphasis on areas of old-growth forest and limestone karst landscapes, and strengthening of ex-situ living collections, is recommended.

The diversity of the Begonia flora of the southwestern arm of Sulawesi and the adjacent Selayar Islands, South Sulawesi province, Indonesia, is reassessed, and distribution maps, provisional IUCN conservation category assessments, and an identification key to 14 recognised species are provided. One new species from the Selayar Islands, Begonia enoplocampa, is described and a photo plate is presented. This species is the first record of Begonia section Jackia in South Sulawesi province. Newly available material allowed a reassessment of the morphological variability of several species that were originally described from very limited material. Resulting revised descriptions and photo plates of Begonia comestibilis, B. hooveriana, B. ozotothrix, B. prionota and B. siccacaudata are presented. Begonia hooveriana is lectotypified.
