Barbosella-orbicularis-2023-05-11 *SITF confirms this plant is Barbosella orbicularis (May 2023).
The flower size is correct at .3 cm and the leaves are sub-orbicular, which matches the description for this species. The article, "New Species and Records of Orchidaceae from Costa Rica" in Lankesteriana by Bogarin, Karremans & Pupulin contain the description and drawing of B. orbicularis which matches this plant. The species is easily recognized by its creeping habit and rounded, smooth, overlapping leaves and tri-lobed lip; in the Award Description, the judges described the lip as having two structures, which they termed "incurved lobules", which could be interpreted as keels. Supporting matching photos may be found in the IOSPE, OW and orchidroots.com.
