The family Eriocaulaceae is represented only by the genus Eriocaulon L. in Asia. However, the circumscription of the genera and the total number of species in Indochina region remains unclear. An account of the genus in the flora of Cambodia, Laos and Vietnam is in progress. Field collection in central and southern Laos was undertaken between 2010 and 2013. Six hundred specimens from various herbaria, including E, K, P & VNM, have been consulted. The study leads to the recognition of 50 species, including 12 new taxa. Of these, five species of them are found only in CLV. This presentation will highlight all new taxa of Eriocaulon across Cambodia, Laos and Vietnam and will discuss these in the context of current understandings of taxonomic characters. A better knowledge of these studies will help us understand the flora of the region more fully and contribute to global conservation assessments for the family.
