Two new species, Ophiopogon dolichocaulis and O. trigonantherus (Asparagaceae), from northern Vietnam

Abstract

Two new species of Ophiopogon, O. dolichocaulis from Son La Province and O. trigonantherus from Cao Bang Province in northern Vietnam, are described and illustrated. The former is similar to O. chingii, while the latter is similar to O. rupestris and O. dracaenoides. This paper not only details their taxonomic features and relationships to similar species but also provides ecological data on their habitats and phenology.

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).…”
