New nomenclatural and taxonomic adjustments in Dracaena (Asparagaceae)

Abstract

Recent molecular phylogenetic studies showed that the genus Sansevieria (excluding S. sambiranensis) forms a monophyletic clade nested within the paraphyletic genus Dracaena. Consequently, the genus Sansevieria was sunk into the genus Dracaena and new combinations were published to accommodate the transfer of taxa from Sansevieria into Dracaena. Since the inclusion of Sansevieria into Dracaena, new taxa have been published in Sansevieria. This paper presents fourteen name changes including twelve new combinations in Dracaena and two rank adjustments, one new synonym, and one lectotypification aiming at further standardisation of the taxonomy of Dracaena.

An exopolysaccharide-producing novel Agrobacterium pusense strain JAS1 isolated from snake plant enhances plant growth and soil water retention

“…Sansevieria as a genus (maintained in the manuscript hereafter; although very recently sunken into genus Dracaena 45 ), comprises slow-growing succulent plants, commonly referred to as ‘snake plants’ within the family Asparagaceae and include around 70 species of the principally considered ornamentals native to South Africa, South Asia, and Madagascar. They are shade tolerant, can withstand arid, semi-arid, high salt soils, and grow mostly through stolons 46 .…”
