Vaccinium sulawesiense Mustaqim & P.W.Fritsch, a newly discovered species endemic to Sulawesi, Indonesia, is described. This species is similar to V. simulans Sleumer but differs in having an acuminate leaf apex, larger floral organs, and an absence of trichomes in the upper half of the inner surface of corolla and disk. This species is known from two specimens, one from a mid-montane rainforest in Mamasa Regency, Sulawesi Barat Province, and the other from Poso Regency, Sulawesi Tengah Province. An updated list of the 17 known Vaccinium species in Sulawesi is also provided.
