Aspidistra nikitensis is described and illustrated as a new species from Gia Lai province of Vietnam. The new species possesses linear leaves and trimerous flowers with a mushroom-shaped pistil. In these features, the new species is morphologically similar to A. hainanensis species complex but differs in its convex stigma with projections. In stigma structure, A. nikitensis resembles A. longanensis but differs in shape of leaves and flower merism.

Peliosanthes oksanae is described and illustrated as a new species from eastern Thailand. It is most similar to P. gracilipes known from northern and southwestern Thailand and northwestern Laos, from which it differs mainly by the shorter flowering stem, flowers borne singly or binately in the axils of the bracts and almost free oblong filaments not forming a typical corona. We briefly discuss taxonomic relationships between P. oksanae and two similar species, P. gracilipes and P. caesia. It is notable that especially P. oksanae and P. gracilipes are close in floral characters to Ophiopogon. We also report P. triandra, which was described from southern Cambodia, as new to Thailand. Both P. triandra and P. oksanae occurred in the same habitat.

Peliosanthes luteoviridis is described and illustrated as a new species from southern Vietnam (Dong Nai Province, Cat Tien National Park). It is most similar to P. macrostegia in having stamens forming a hemispheric corona and a pistil somewhat abruptly narrowing to a conoid style, but differs mainly in dense inflorescence, terete peduncle, entirely yellowish green flowers and somewhat thin-textured translucent perigone.
