Rediscovery of Thottea philippinensis(Aristolochiaceae) from Naga‐Kabasalan Protected Landscape, Zamboanga Sibugay including the confirmation on the occurrence ofT. tomentosain the Philippines

Abstract

Collecting expeditions carried out in the Zamboanga Peninsula of western Mindanao (Philippines) led to the rediscovery of Thottea philippinensis, previously known only by a single collection made 93 years ago. Here we provide an extended description, 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, the occurrence of T. tomentosa in the Philippine archipelago is confirmed.
