An earlier type designation for a Philippine taxon of the tribe Guettardeae to Timonius pachyphyllus Merr. is found to be erroneous, because the specimen designated is inconsistent with the original material as it clearly represent a different species. To clarify the application of the name T. pachyphyllus, it is thus lectotypified here with a specimen housed in the Museum national d'Histoire naturelle, Herbier national de Paris (P).
