Owing to shortage of time, this most precious element in the life of a taxonomist, nearly two years have elapsed since the last number (10) appeared (Febr. 1953). It should not be understood that our interest in editing this Bulletin has waned; we still regard it as a useful bond between Flora Malesiana Foundation, its collaborators, and its sympathizers. It also aims to chronicle some selected miscellaneous news to many people in Malaysia who are far from libraries or have only limited facilities to keep informed about progress. It tries to assemble data on activities of botanical work in the wide sense performed in the Malaysian area. Much work that is done in the field or is going on in establishments of forestry and botany in the Malaysian tropics is often locally known or published in technical reports which hardly reach the scientific botanic world. There is, hence, a field of mutual interest which this Bulletin tries to cover.
