RESUMEN
Following ongoing ecological research on the tree diversity of the Indonesian island of Sulawesi, we describe five new species of Syzygium. These are the first descriptions of Syzygium species from the island since Blume (1850, Jambosa celebica and J. cornifolia), highlighting the significant lack of taxonomic research on the genus for the region. The five species proposed as new are Syzygium balgooyisp. nov., Syzygium contiguumsp. nov., Syzygium devogeliisp. nov., Syzygium eymaesp. nov., and Syzygium galanthumsp. nov. All species are illustrated and information on their distribution, ecology, and conservation status is given.
RESUMEN
A new species of Syzygium Gaertn. (Myrtaceae), Syzygiumpyneei Byng, V. Florens & Baider, is described from Mondrain Reserve on the island of Mauritius. This species is endemic to the island and differs from any other species by its combination of cauliflory, relatively large flowers, light green to cream hypanthium, light pink stamens, short thick petioles, coriaceous leaves and round, cuneate or sub-cordate to cordate leaf bases. Syzygiumpyneei Byng, V. Florens & Baider is known from only two individuals from the type locality and merits the conservation status of Critically Endangered (CR C2a(i,ii); D).
