Abstract

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 of T. tomentosa in the Philippine archipelago.
