Note.

The original material cited in the protologue comprises the type collection and a paratype, Picheansoonthon & Phokham 150711-1 (BKF, n.v.), collected in the same place as the type, on 15 Jul 2011. The first author travelled towards the GPS coordinates given in the protologue, stopping at the nearest village to ask whether anyone remembered the Thai collectors who had visited the area in 2011. The villagers did remember and were able to give directions to the type locality. O. Insisiengmay OI-2 was collected at the type locality and matches the description in the protologue. It is designated here as the neotype.
