Abstract

A new species of blueberry, Vaccinium coarctatum M.N.Tamayo & Fernando, from the dwarf forest on ultramafic soil of Dinagat Island, Philippines, is described. It closely resembles Vaccinium hamiguitanense P.W.Fritsch but is distinct from that species in having a longer inflorescence, shorter pedicels, longer and persistent bracteoles, white-hirsutulous calyx lobes, and shorter anther spurs. This discovery brings the number of Vaccinium species known from the Philippines to 41. A key to the small-leaved Vaccinium in the Philippines is provided.
