Determined to be Oberonia leytensis, not Oberonia mindorensis (July 2021) with the help of Dr. Daniel Geiger; this flower has the characteristics of O. leytensis: O. leytensis has a strong V-shaped callus on the center of the lip, which is absent in O. mindorensis; O. leytensis has erose, square margins of the epichile, where O. mindorensis margins are rounded and entire; O. leytensis typically has orange coloration, whereas O. mindorensis is usually yellow; this is a good match to the line drawing and photo in the IOSPE.
