Begonia tabonensis is an endemic species of Begonia discovered in Tabon Cave, Lipuun Point, Municipality of Quezo, in Palawan, Philippines.[1][2] This species resembles B. mindorensis Merr., widely ovate and uniformly green leaves, and inflorescence with sessile glands. However the two species differs on several characteristics: Begonia tabonensis have shorter petioles(10 cm long), smaller leaves(4-8 x 4–6.4 cm); deciduous, chartaceous, glabrous or very sparsely glandular bracts; and slightly pointed, crescent-shaped ovary wing; whereas, B. mindorensis have longer petioles(25 cm long), larger leaves(10-15 x 6-10 cm); persistent, coriaceous, densely glandular bracts; and acute, triangular ovary wing.[2]
