Table 3. Morphological comparisons between Polyalthia evecta -3 [= P. esanensis Wiya, Damth. & Chaowasku sp. nov.], P. evecta -4 [= P. acuminatissima Wiya, Damth. & Chaowasku sp. nov.], P. evecta -2 [= true P. evecta (Pierre) Finet & Gagnep.] and P. chantaranothaii Bunchalee & Chalermglin. Data for the true P. evecta are from Pierre (1881) and personal observations; data for P. chantaranothaii are from Bunchalee et al. (2021b) and personal observations.
