This paper provides descriptions and photographic illustrations for two new species and one new variety; Ophiopogon brevicaulis from N. Vietnam, Rohdea subcaudata from central Laos, and O. dracaenoides var. pleianthus from N. Vietnam. Five species are recorded as new to the flora of Vietnam; O. peliosanthoides, O. pingbienensis, O. reversus, O. xylorrhizus, and Peliosanthes pachystachya, two of which, O. peliosanthoides and O. pingbienensis, are illustrated. Data on the distribution and illustrations of O. intermedius in Vietnam are also provided, as the species there has not yet been sufficiently known.
