Abstract
Medinilla calanasan is here described as a new species from Calanasan in Apayao Province in northern Luzon (Philippines). It is morphologically distinct from all other known Medinilla species in having horn-like protrusions at the base of the leaf lamina. Morphological similarities with M. clementis Merr. and M. dolichophylla Merr. suggest that M. calanasan may be a member of the M. magnifica-alliance.
