Pelseria is a monotypic genus of flowering plants in the sunflower family, Asteraceae, belonging to the tribe Senecioneae.[3] It was established in 2026 by segregating the species formerly known as Senecio otites from the genus Senecio.[3][4]
Description
[edit]Plants of Pelseria are perennial herbs exhibiting large leaves that are conspicuous petiole, and stipules that possess auricles.[3] The morphology of the style features a subconvex tips that have short sweeping-hairs and resembling those from the genera Dendrophorbium and Hoehnephytum.[3]
Species
[edit]The genus contains a single species:[5]
Pelseria otites (Kunze ex DC.) S.E.Freire & Urtubey[1] – the type species of the genus, previously classified as Senecio otites Kunze ex DC.
Etymology
[edit]The genus name Pelseria honors Professor Pieter B. Pelser, a Dutch botanist at the University of Canterbury in New Zealand.[4] Dr. Pelser is recognized for his contributions to the phylogeny and taxonomy of the tribe Senecioneae,[3][4] and is an acknowledged plant biologist of the Philippines through the Co's Digital Flora of the Philippines website.[4]
Distribution and habitat
[edit]Pelseria is known only to southern South America, occurring in southern Argentina and Chile at elevations ranging from 600 to 1,300 meters.[3][4]
Phylogeny
[edit]Molecular evidence from nuclear and plastid DNA sequences places Pelseria in a clade with Graphistylis dichroa, Hoehnephytum trixoides, Dendrophorbium bomanii, and Arbelaezaster ellsworthii.[3] This phylogenetic position supports its segregation from Senecio.[3]
