Flora Malesiana

Flora Malesiana is a multi-volume flora describing the vascular plants of Malesia (the biogeographical region consisting of Indonesia, Malaysia, Singapore, Brunei, the Philippines, and Papua New Guinea), published by the National Herbarium of the Netherlands since 1950. It currently consists of 204 full treatments, covering about 20% of a total of approximately 40,000 species.

Main series
Flora Malesiana is divided into two main series: I. Seed plants and ''II. Pteridophytes''. Later volumes include CD-ROMs with additional multimedia content such as interactive keys.

Digitalization
In 2010 an initiative was taken to make all of the contents of Flora Malesiana available though a website, as a so-called e-flora (the 'e' standing for 'electronic' or 'enhanced'). This initiative was taken because (1) the overall progress of Flora Malesiana in terms of the number of species covered is too slow (about 80% of all species in Malesia still need to be treated) to make a timely contribution towards sustainability and conservation, and (2) several volumes of Flora Malesiana are out-of-print.
