[Botany • 2022] Lycoris longifolia (Amaryllidaceae) • Phylogenomic and Morphological Evidence reveal A New Species of Spider Lily from Sichuan, China


Lycoris longifolia L.H.Lou, 

in Lou, Ma, Jin, Wang, ... et Liu, 2022. 
 
Abstract
Lycoris longifolia, a new species from China, was described and illustrated here. Our phylogenomic evidence based on whole plastomes strongly supported the separate phylogenetic position of this new species, and morphologically it could also be distinguished by its long leaves with a distinct purplish-red midrib on the abaxial surface.

Keywords: Lycoris, morphological, phylogenomics, whole plastome

 Lycoris longifolia L.H.Lou, sp. nov.
 Chinese name: 长叶石蒜  

Diagnosis: Most similar to L. aurea but differs from it by markedly longer leaves, abaxially with a distinct purplish-red midrib.
 
Etymology: The specific epithet alludes to length of leaf blades, a diagnostic character.

Distribution: This new species has been narrowly discovered in Ya’an, Sichuan, China. Some localities of Southwestern China have been poorly discovered, and a comprehensive floristic investigation will help elucidate the germplasm resources.
