Description
Summary:The names Werneria melanandra and W. pygmophylla are transferred to the genus Senecio . They belong to the group of the discoid caespitose Andean Senecio , specifically to the subgroup with blackish anthers and style branches and whitish corollas. The recognition of S. digitatus as a distinct species is also discussed. Within the framework of the mentioned group, the names S. casapaltensis and S. macrorrhizus are lectotypified, S. humillimus var. melanolepis is neotypified, an epitype is designated for the name W. melanandra , and nine new synonyms are proposed. An updated comprehensive dichotomous key including all discoid caespitose Senecio species from Bolivia and Peru is provided.
