Six new species, Ophiopogon fruticulosus Aver., N.Tanaka & K.S.Nguyen, sp. nov., O. petraeus Aver. & N.Tanaka, sp. nov., Peliosanthes densiflora Aver. & N.Tanaka, sp. nov., P. hexagona Aver., N.Tanaka & K.S.Nguyen, sp. nov., P. lucida Aver., N.Tanaka & K.S.Nguyen sp. nov. and Tupistra breviscapa Aver. & N.Tanaka, sp. nov. (Asparagaceae) discovered in Laos or Vietnam are described and illustrated. Ophiopogon bockianus Diels is newly recorded for the flora of Vietnam. Ophiopogon mairei H.Lév. is regarded as a synonym of O. bockianus. The name Ophiopogon hayatae (N.Tanaka) N.Tanaka, Aver. & T.Koyama, comb. nov., stat. nov. is proposed as a new nomenclatural combination and status. Except for O. bockianus (= O. mairei), the other seven species here reported are endemic either to Vietnam (five species) or Laos (two species).
