This specimen was collected in Malayisa.The micro-undulatum clade is restricted to the western expanses of the geographical range of Mitthyridium. It is found in Peninsular Malaysia west to islands of the Pacfic Ocean, specifically the Seychelles and the Comoros. It is often found on trees like coconut palms below 300 m. The clade's closest relative is obtusifolium, its Pacific Ocean counterpart that is far more restricted in geographic range.
