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.

“…

According to Escobar (2012), there are two kinds of floral appendages around the staminal tube or urn in Miersia: 1) the upper pair of appendages are of staminal origin and 2) the four lateral appendages, one pair on each side of the staminal tube, are of tepaliferous origin. Consequently, mentions to "tepaliferous appendages" in diagnoses, descriptions, identification key and figure captions of our recent article (García et al 2022) should be changed to "floral appendages", to denote the mixed nature of those structures in most species of Miersia.
