According to the latest taxonomic study of Pavetta L. in Thailand, 14 species and two varieties are recognised. However, this work was based mainly on morphological data and included some species with considerable morphological variation. Therefore, the taxonomic status of some species and infraspecific taxa is still uncertain and a re-evaluation is needed for clarification. This study focuses on whether the two varieties of P. Tomentosa Roxb. ex Sm., P. tomentosa var. tomentosa and P. tomentosa var. glabrescens (Kurz) Bremek., are sufficiently distinct, as they are distinguished only by the degree of pubescence on various parts, with unclear boundaries between character states. To clarify the status of these taxa, we compared the leaf epidermis of representative individuals of P.tomentosa with different degrees of leaf hairiness using a peeling technique. The results revealed that P. Tomentosa var. tomentosa and P. tomentosa var. glabrescens have similar leaf epidermal anatomy. No leaf epidermal anatomical characters were found that clearly support the recognition and separation of the two varieties.
