New And Noteworthy Species Of Ophiopogon And Peliosanthes (Asparagaceae) From Laos, Vietnam And Thailand

We describe and illustrate Ophiopogon robustus and Peliosanthes rubra from northern Laos and P. convallarioides from central Vietnam as species new to science. Ophiopogon robustus is close to O. platyphyllus from southern China, P. rubra is similar to P. densiflora from Laos and P. convallarioides is close to P. argenteostriata from Laos and Vietnam. We reduce P. lucida described from northern Vietnam to P. dasystachys. Finally, we record and illustrate P. campanulata from Thailand, and provide new data on the distribution of P. teta in Laos and Vietnam.
