This internship is focused on the revision of the Malesian species of Excoecaria (euphorbiaceae).
Probably Excoecaria has 6 species in Malesia, which need revision. One species, E. agallocha, the only one with only alternate leaves, is only growing in the mangrove or close to salt water, while all other species (usually) have opposite leaves. The flowers are very reduced (see drawings). Typical are the solitary flowers on long pedicels. One species, E. oppositifolius, is sometimes seen as a very broad, diverse species, sometimes it is split up in various species. The genus has to be revised for treatment in Flora Malesiana and a preliminary revision is present.
Objectives and goals
The project is targeted at determining the species of Excoecaria that occur in Malesia and their variation.
The project aims to publish the results in a journal, on the Euphorbiaceae website and finally in Flora Malesiana.
