Two new species of Bulbophyllum, B. barcelonae and B. pelseri are described here from the Pantabangan-Carranglan Watershed Forest Reserve, Luzon Island, Philippines. Bulbophyllum barcelonae resembles B. charisae, but differs by having smaller vegetative parts, ovate petals with a rounded apex, and a labellum with two ridges that are strongly angled outwards the adaxial surface, rounded proximal crests, and a canaliculate abaxial surface. Bulbophyllum pelseri resembles B. aureobrunneum but differs by having caducous sheath covering the pseudobulbs, punctulate leaf surface, shorter leaves, absence of transverse callus in median portion of labellum, median portion with short, rounded ridge, rounded apex, and triangular stelidia. These discoveries increase to 207, the known species of Bulbophyllum in the Philippines.
