Notes

What has been understood as I. ovalis in numerous floras of SE. Asia and Malesia, belongs partly to other species of the genus, mainly to I. cirrhosa TURCZ., I. philippinensis MERR. and I. vitiginea HANCE.
I. ovalis Bl. was mentioned by and for New Guinea (Morobe Distr., once found by WARBURG), but the specimen is lost and its identity remains uncertain. There is no recent record of Iodes from New Guinea.
