New taxa and taxonomic notes in Aspidistra (Convallariaceae s.s.) of Laos and Vietnam

Abstract

This paper continues the publication of newly obtained results from a continuing taxonomic investigation of the genus Aspidistra in Laos and Vietnam. It includes diagnoses of two new species, A. medusa Aver., K. S. Nguyen & Tillich and A. triquetra Aver., Son, Tillich & K. S. Nguyen and amended descriptions of A. khangii Aver. et Tillich and A. locii Arnautov & Bogner previously only known from incomplete material. A lectotype of A. locii is proposed. Color illustrations, new or updated data on morphology, ecology, phenology, tentative relationships, distribution and conservation status are provided for all the mentioned taxa.

New taxa and new records in Aspidistra (Convallariaceae s.s.) of Laos and Vietnam

“…Available data indicate eastern Indochina as the largest center of species diversity of this genus. The most recent results of investigations in this area have been summarized in a series of recent publications (Averyanov and Tillich , , Averyanov et al , , , b, , b, Vislobokov 2015, , Vislobokov et al , , Nguyen et al , , Nuraliev et al , Tillich et al , Tillich and Averyanov ). Meanwhile, the diversity of the genus is still far from well known and understood.…”

New species of Aspidistra (Convallariaceae s.s.) in the flora of Vietnam

“…Presently, more than a hundred species, which represent at least 70–75% of the currently known taxa, are found in this region. Though many species have been discovered during last years (Averyanov and Tillich 2016, 2017, Averyanov et al 2016, 2017, 2018a, b2018b, 2019a, b2019b, Vislobokov 2016, Vislobokov et al 2016, 2017, 2019, Nguyen et al 2017, 2020, Nuraliev et al 2017, Tillich et al 2017, Tillich and Averyanov 2018) our knowledge on species composition and distribution of many species in this area remains incomplete. The data reported in this paper provide new additional information obtained during fieldwork and garden observations in 2016–2020.…”
