| Sumatra and Peninsular Malaysia are both part of Sundaland together with Borneo and Java. Vegetation studies by Laumonier (1990, 1997) show the Sumatra flora is most similar to that of the Peninsula (sharing 49% of species) compared with those of Borneo (45%) or Java (37%). From the literature, opinions about the Sumatran flora seem contradictory. On the one hand, Van Steenis (1987) noted the peculiarity of the low number of endemic genera in Sumatra, 13, compared with 24 in Peninsular Malaysia (Johns, 1995). On the other hand, Sumatra boasts one of the two Malesian endemic families, the Pentastemonaceae, while the Peninsula has none. |

| The morphology and leaf anatomy of Myxopyrum is described and a key to the species is given. Of the 15 species previously described four species and two subspecies are recognised: M. nervosum Bl. (synonyms M. horsfieldii, M. zippelii) with one subspecies coriaceum (Bl.) Kiew (synonym M. ellipticum), M. ovatum Hill (synonyms M. macrolobum, M. cordatum, M. philippinensis), M. pierrei Gagnep. (synonym M. hainanense) and M. smilacifolium Bl. (synonym M. serrulatum) with one subspecies confertum (Kerr) Kiew. Myxopyrum enerve Steen. is Chionanthus enerve (Steen.) Kiew. Descriptions for the extra-Malesian species, M. smilacifolium, is given. |

| 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. |
