New and noteworthy species of Ophiopogon and Peliosanthes (Asparagaceae) from Laos, Vietnam and Thailand

Abstract

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.

Peliosanthes maheswariana D.Borah, N.Tanaka & Taram, sp. nov. (Asparagaceae), from Arunachal Pradesh, NE India, and P. sinica new to India

“…Recently, many new taxa of this genus have been described especially from eastern Indochina (e.g. Tanaka & Kalyuzhny 2020; Averyanov et al 2021; Nguyen et al 2021; Vislobokov et al 2022) and northeastern India. From the latter region, nine species and one variety have been reported as new since 2017 (Roy et al 2017, 2020; Tanaka 2018, 2019; Borah et al 2020; Odyuo et al 2020; Taram et al 2020).…”
