Two new species of Miersia and their phylogenetic placements alongside the recently described M.putaendensis (Gilliesieae, Allioideae, Amaryllidaceae)

Abstract

Two new species of the Chilean endemic genus Miersia (Gilliesieae, Allioideae, Amaryllidaceae) are described, M.stellata and M.raucoana, alongside morphological descriptions, a distribution map, illustrations, conservation status assessments, and an updated key to all species of Miersia. Additionally, phylogenetic analyses of DNA sequences were performed to inquire into the evolutionary affinities of both new species and the recently described, M.putaendensis, within the tribe Gilliesieae.

Keywords: Alliaceae; Central Chile; IUCN; phylogeny; taxonomy.
