Dendrobium macranthum

A lowland epiphytic Dendrobium of the south-west Pacific, found in Vanuatu, New Caledonia, the Santa Cruz Islands and Wallis and Futuna, and described by Achille Richard in 1834. It grows in primary forest near sea level, so it wants warm, humid, bright conditions all year. Detailed ecological information on the species is scarce.
