Collecting expeditions carried out in the Zamboanga Peninsula of western
Mindanao led to the rediscovery of Thottea philippinensis ,
previously known only by a single collection made 93 years ago in the
Philippines. Thus, in this paper, we provide descriptions, comments on
the affinities among closely related species, an updated geographical
distribution, habitat information, conservation assessment, and the
first-ever published photos of living T. philippinensis in the
wild. Additionally, we include notes on confirming the occurrence ofT. tomentosa in the Philippine archipelago.
