Biology:Pelseria
Pelseria is a monotypic genus of flowering plants in the sunflower family, Asteraceae, belonging to the tribe Senecioneae.[1] It was established in 2026 by segregating the species formerly known as Senecio otites from the genus Senecio.[1][2]
Description
Plants of Pelseria are perennial herbs exhibiting large leaves that are conspicuous petiole, and stipules that possess auricles.[1] The morphology of the style features a subconvex tips that have short sweeping-hairs and resembling those from the genera Dendrophorbium and Hoehnephytum.[1]
Species
The genus contains a single species:[3]
Pelseria otites (Kunze ex DC.) S.E.Freire & Urtubey[4] – the type species of the genus, previously classified as Senecio otites Kunze ex DC.
Etymology
The genus name Pelseria honors Professor Pieter B. Pelser, a Dutch botanist at the University of Canterbury in New Zealand.[2] Dr. Pelser is recognized for his contributions to the phylogeny and taxonomy of the tribe Senecioneae,[1][2] and is an acknowledged plant biologist of the Philippines through the Co's Digital Flora of the Philippines website.[2]
Distribution and habitat
Pelseria is known only to southern South America, occurring in southern Argentina and Chile at elevations ranging from 600 to 1,300 meters.[1][2]
Phylogeny
Molecular evidence from nuclear and plastid DNA sequences places Pelseria in a clade with Graphistylis dichroa, Hoehnephytum trixoides, Dendrophorbium bomanii, and Arbelaezaster ellsworthii.[1] This phylogenetic position supports its segregation from Senecio.[1]
