| Following the revision of Peninsular Malaysian Begonia, a project that involved extensive fieldwork, we now have sufficient data to assess their conservation status. Out of 54 taxa, 48 are endemic to Peninsular Malaysia. No fewer than 30 taxa are known from fewer than five localities; 24 taxa are Critically Endangered (CR), 3 are Endangered (EN) while 4 are Vulnerable (VU). One taxon is Extinct (EX), the 22 remaining are Near Threatened (NT), Least Concern (LC) and Data Deficient (DD). We discuss how the assessment was carried out and the implications for the long-term conservation of Begonia. The most significant conservation measure proposed here is the gazettement of limestone hills as totally protected areas. |

| Based on distributional data of 40 species of Peiratinae, historical relationships of five Amazonian areas (Paranaense, Atlantic, Pacific, Amazonian, and Cerrado) and two Chacoan areas (Chaco and Caatinga), were investigated through a parsimony analysis of endemicity (PAE). The resulting area cladogram indicates the following sequence of area fragmentation: (Cerrado (Caatinga (Chaco, ((Pacific, Amazonian), (Atlantic, Paranaense))))). It is proposed that these results reflect the gradual development of a diagonal of open formations (Chaco-Cerrado-Caatinga), which separated the former continuous tropical forest into two parts, namely, northwestern (Pacific plus Amazonian) and southeastern (Paranaense plus Atlantic). |
